The waste treatment process includes, for example, as shown in FIG. 1, a discharge process P1, a collection and transportation process P2, a storage process P3, and a disposal process P4.
The discharge step P1 is a step in which, for example, a remodeling business operator (one example of a recycle business operator) who has received an order from a customer for a building remodeling business discharges the waste generated by the remodeling work. Here, this renovation business operator develops a business in a franchise format, and has a headquarters as a discharge business operator and a member store. However, the emission business may not be a franchise-type business and may be a single business. Therefore, hereinafter, the renovation company may be simply referred to as an “emission company” without distinguishing between the headquarters and the member stores.

The collecting and transporting step P2 is a step in which a collecting and transporting company collects and transports waste and transports it to a predetermined storage location.

The storage process P3 is a process in which the storage company stores the waste in the storage facility. Note that the storage company may be included in the above-mentioned collection/transportation company in the storage process P3, since a work of collecting and transporting waste may occur as necessary in this storage process P3.

The disposal process P4 is a process in which the disposal company disposes the waste. Note that the disposal company may be included in the above-mentioned collection/transportation company in the disposal process P4, since a work of collecting and transporting waste may occur as necessary in this disposal process P4.

As shown in FIG. 2, the waste treatment management system 10 includes waste discharger terminals C1 and C2, a collection transporter terminal MD, and a waste treatment management server SVG, and manages waste treatment based on an electronic manifest. it can. The discharge company terminals C1 and C2, the collection and transportation company terminal MD, and the waste treatment management server SVG are connected to each other via the Internet (an example of a network) N.
Here, the Internet N is connected to an electronic manifest system (JWNET server SVJ) operated by the Japan Industrial Waste Treatment Promotion Center (hereinafter referred to as “information processing center”). That is, the information processing center (JWNET server SVJ) can be accessed from each of the discharge company terminals C1 and C2, the collection and transportation company terminal MD, and the waste processing management server SVG.

The discharge company terminals C1 and C2 are terminals operated by the above-mentioned reform company. The discharging company terminal C1 and the discharging company terminal C2 are, for example, computers installed at the locations of the headquarters and member stores, respectively.
In the waste treatment management system 10, the member store may perform the operation or work performed by the head office instead, or the head office may perform the operation or work performed by the member store instead.

The collection and transportation company terminal MD is a terminal operated by the collection and transportation company, and is, for example, a mobile terminal carried by a person in charge of the collection and transportation company. This mobile terminal has a camera and a GPS function.
The collection and transportation company terminal MD may be any computer as long as it can be connected to the Internet N, and may be a computer installed at the location of the collection and transportation company. Further, a plurality of collection/transportation carrier terminals MD may exist for one collection/transportation carrier.

The waste treatment management server SVG is a server operated by a management company that manages the treatment of waste.
As shown in FIG. 3, the waste treatment management server SVG includes a storage unit 202, a trader selection unit 203, a delivery confirmation information transmission unit 204, a position information confirmation unit 205, an update unit 206, and first to fifth condition determination units. It has 208a to 208e and a contract creating means 210.
Each of these means is realized by the waste treatment management server SVG by a program executed by the waste treatment management server SVG.

The storage unit 202 has, for example, a hard disk drive device, and as shown in FIG. 4, can store delivery confirmation information, temporary registration information, a database of collection and transportation companies, processing fee information, and transportation destination location information.
The delivery confirmation information includes at least information described on the delivery confirmation slip in the electronic manifest system, and includes first information, second information, and third information.

The first information is information provided by the waste discharger accessing the waste treatment management server SVG. For example, the manifest number, the customer name (reform requester name), the zip code of the customer's house, and the waste. Address of the customer's house (collection location of waste), delivery construction slip number, planned discharge date, work process date, remodeling type, registration cooperation company (substantially based on the request of the remodeling company) It includes information on the renovation company that performs building renovation work, collection conditions, and waste emission forecasts. The collection condition is information such as the type of collection vehicle, the presence/absence of special collection that needs to be carried out or carried by two people, and the planned discharge amount of waste.
The second information is information provided by the trader selection means 203 or the management company, which will be described later, and is, for example, the name and location of the collection and transportation company.
The third information is information provided by the collection and transportation company accessing the waste treatment management server SVG. For example, the date of delivery, the discharge amount of each waste item, the packing form, and the waste amount. Information such as the location of the transportation destination (disposal site, etc.), waste disposal method, vehicle number, vehicle name, etc.

The temporary registration information is at least information including manifest information and information of a plurality of photographs with position information including position information of the shooting location where the waste was shot.
The manifest information is information registered in the electronic manifest system, and is configured based on the delivery confirmation information.
The plurality of photographs with position information are a photograph P1 of waste taken by the collection and transportation company at the collection destination and a photograph P2 of waste taken at the transportation destination, respectively. The position information of the shooting location acquired using GPS is associated with each of the photographs P1 and P2.

The collection and transportation company database is a database in which a plurality of collection and transportation companies are registered. Information (names, locations, etc.) of a plurality of collection and transportation companies is registered in this database. In addition, each collection and transportation company registered in this database is a highly reliable company that has been examined by the management company to meet predetermined criteria.

The processing fee information is information on the fee for processing the waste set by each of the plurality of collection and transportation companies. The treatment fee is set by each collection and transportation company accessing the waste treatment management server SVG.
The processing fee consists of collection and transportation costs, disposal costs, industrial waste tax, and additional fees (costs such as the distance to the waste collection destination and the burden of loading work).

The transportation destination location information is information on the location of the transportation destination where the collection and transportation company transports the waste, and is preset by the management company. The location of the transportation destination is, for example, the location of the disposal site.

The trader selection means 203 processes the waste based on the location of the collection destination of the waste (address of the customer's house), the location of the collection transporter, and the processing fee information of each collection transporter stored in the storage means 202. You can calculate the charge and select the collection and transportation company with the lowest processing charge.

The delivery confirmation information transmitting means 204 can transmit the delivery confirmation information to the collection and transportation company terminal MD via the Internet N.

The position information confirmation unit 205 detects that the position included in the information of the photo P1 is within a preset distance range from the information of the location of the collection destination, and the position included in the information of the photo P2 is from the information of the location of the transportation destination. It can be confirmed that the distance is within the preset distance. The range of this distance is stored in the storage unit 202.

The update unit 206 can update the manifest information stored in the storage unit 202 based on the latest manifest information registered in the electronic manifest system. The updating unit 206 can update the manifest information for each predetermined period.

The first condition judging means 208a can judge whether the first condition is satisfied. The first condition is that the position included in the information of the photo P1 is within a preset distance from the information of the location of the collection destination included in the delivery confirmation information, and the position included in the information of the photo P2 is That is, it is within the range of a preset distance from the delivery confirmation information or the location information of the delivery destination included in the delivery destination location information.
Therefore, when the above-mentioned position information confirmation means 205 confirms that the position information associated with the photographs P1 and P2 of the waste is within the range of the preset distance from the locations of the collection destination and the transportation destination, respectively. The first condition determination unit 208a determines that the first condition is satisfied.

The second condition determining means 208b can determine whether the second condition is satisfied. The second condition is that the amount of waste obtained from each of the photographs P1 and P2 and the amount of waste input by the collection and transportation company via the terminal of the collection and transportation company match. It should be noted that the term “match” here does not mean a match in a strict sense. That is, “match” means “substantial match” in which a predetermined degree of mismatch is allowed (hereinafter the same).
The amount of waste is obtained from each of the photographs P1 and P2 by using, for example, AR (Augmented Reality).

The third condition determining unit 208c can determine whether the third condition is satisfied. The third condition is that the waste recorded in the photo P1 and the waste recorded in the photo P2 are the same as the type of waste input by the collection and transportation company via the terminal of the collection and transportation company. is there. It should be noted that the term “identical” here does not mean the same in a strict sense. That is, “identical” means “substantially identical” in which a predetermined degree of disparity is allowed (hereinafter, the same).
The types of the waste recorded in the photograph P1 and the waste recorded in the photograph P2 are obtained by image processing using, for example, AI (Artificial Intelligence).

The fourth condition determining means 208d can determine whether or not the fourth condition is satisfied. The fourth condition is that the manifest information configured based on the delivery confirmation information is main-registered in the electronic manifest system.
The fourth condition determining unit 208d monitors that the manifest information is main-registered in the electronic manifest system, and determines that the fourth condition is satisfied when the main registration is performed.

The fifth condition determining means 208e can determine whether the fifth condition is satisfied. The fifth condition is that the discharge business operator or the management business operator approves the collection and transportation company to execute the settlement process.
The fifth condition determining unit 208e monitors that the discharging business operator or the management business company approves the execution of the settlement process, and when the approval is made, determines that the fifth condition is satisfied.

The contract creating means 210 can create a smart contract for the block chains BC1a, BC1b, BC1c, BC1d, BC1e, BC2, and BC3 that have been built in advance.
The contract creating means 210 will be described later.

Next, a waste treatment management method using the waste treatment management system 10 (excluding settlement processing for a collection and transportation company) will be described with reference to FIG. It should be noted that, if possible, the steps shown below may be executed in reverse order or in parallel.

(Step S1)
The discharging company (headquarters or member store) acquires the manifest number in the electronic manifest. The manifest number can be obtained by utilizing the reservation registration provided by the information processing center.
On the other hand, the contract creating unit 210 creates a contract (smart contract) having predetermined conditions and predetermined contents for waste processing corresponding to the acquired manifest number. The specific contents of the smart contract will be described later.
The contract does not have to be created in step S1 and may be created in step S2, step S3, or step S4. The created contract will be registered in the blockchain at an appropriate timing.

(Step S2)
The discharger receives an order from a customer for renovation work. When the details of the reform work are clarified and it is determined that the waste generated by this reform work needs to be treated, the discharge business operator (member store) uses the discharge business operator terminal C2 (see FIG. 2). Then, the first information (see FIG. 4) other than the manifest number included in the delivery confirmation information is registered in the waste processing management server SVG.
The waste management is started by the registration of the first information included in the delivery confirmation information.

(Step S3)

The company selection means 203 (see FIG. 3) of the waste treatment management server SVG selects a collection and transportation company.
In this step S3, the management company manually confirms the delivery confirmation information (see FIG. 4), and based on the delivery confirmation information, it is appropriate for the collection and transportation of the waste from a plurality of collection and transportation companies. You may choose a different collection and transportation company.
Thereafter, the selected collection hauler is arranged.
In addition, since the second information included in the delivery confirmation information is confirmed by this step, the management company registers the second information in the waste treatment management server SVG (see FIG. 2).

(Step S4)
The selected collection and transportation company acquires and confirms the delivery confirmation information stored in the storage means 202 (see FIG. 3) of the waste treatment management server SVG. In detail, the delivery confirmation information transmitting means 204 (see FIG. 3) of the waste treatment management server SVG transmits the delivery confirmation information (see FIG. 4) based on the request from the collection and transportation company.
Next, the collection and transportation company transmits the acquired delivery confirmation information to a remodeling company (a company that substantially carries out the remodeling work of the building based on the request of the remodeling business operator) by using, for example, FAX. The reformer who received the FAX confirms the delivery confirmation information and, for example, when there is a change in the scheduled discharge date, notifies the collection and transportation company of the change.

Next, when the renovation work is performed by the renovation company and the waste is discharged, the collection and transportation company goes to the waste discharge site on the scheduled discharge date included in the delivery confirmation information and collects the waste.
At the waste collection site (collection destination), the collection and transportation company photographs the discharged waste P1 using the collection and transportation company terminal MD (see FIG. 2). This photograph P1 includes the position information acquired at the time of photographing by GPS. After transporting the collected waste, the collection and transportation company uses the collection and transportation company terminal MD to take a picture P2 of the waste at the disposal site of the transportation destination. This photograph P2 also includes the position information acquired at the time of photographing by GPS.
After that, the collection and transportation company uses the collection and transportation company terminal MD to discharge the discharge amount of each waste item and the third information and photographs P1 and P2 included in the delivery confirmation information of the waste and the like (Fig. 4). (Refer) to the waste treatment management server SVG for registration.

The timing of transmitting the third information included in the delivery confirmation information and the photographs P1 and P2 may be arbitrary, and may be sequentially transmitted instead of being transmitted collectively.
Further, when the collection and transportation company terminal MD (see FIG. 2) is a computer installed at the location of the collection and transportation company, the third information and the photographs P1 and P2 may be transmitted using this computer. ..
In this way, the photographs P1 and P2 of the waste with location information taken by the collection and transportation company at the collection destination and the transportation destination are registered, so that the collection and transportation company does not actually carry the waste. Nevertheless, the fraudulent appearance of being transported is suppressed and the process of processing industrial waste is made transparent.

(Step S5)
The first to third condition determining means 208a to 208c respectively determine the success or failure of the first to third conditions based on the third information and the photographs P1 and P2 transmitted from the collection and transportation company terminal MD.
When the first to third condition determining means 208a to 208c determine that the first to third conditions are satisfied, the next step S6 is executed.

(Step S6)
The management company main-registers the manifest information included in the temporary registration information in the electronic manifest system. At that time, the management company transmits the manifest information to the electronic manifest system by the EDI method.
When the manifest information is main-registered, the fourth condition determining means 208d determines that the fourth condition is satisfied, and the next step S7 is executed.

(Step S7)
Each collection and transportation company reports to the electronic manifest system that the transportation of waste has been completed.
Specifically, the collection and transportation company directly accesses the JWNET server SVJ and registers the collection date and the disposal completion date of the waste by using the Web method. Since the commonly used Web method is used for registration, the collection and transportation company can report that the transportation of waste has been completed without hesitation about the operation method.
If a change is required, the fixed quantity of waste is also registered.

However, the waste collection date and the disposal completion date registered in step S7 can be registered in the previous step S6. That is, when the management company knows the waste collection date and the disposal completion date before step S6 is executed, the management company uses the EDI method to collect the waste collection date and the waste information together with the manifest information. The disposal completion date may be registered in the JWNET server SVJ. When the collection date and the disposal completion date of the waste are registered in the previous step S6, the execution of this step S7 is omitted and the next step S8 is executed.

(Step S8)
The updating unit 206 (see FIG. 3) of the waste processing management server SVG updates the manifest information stored in the storage unit 202 based on the latest manifest information registered in the electronic manifest system. The update is executed every predetermined period.

(Step S9)
The discharger confirms the temporary registration information (manifest information and photographs P1 and P2) registered in the waste treatment management server SVG in step S4. If there is no problem in the temporary registration information, the discharger approves the collection and transportation company to execute the settlement process on the waste treatment management server SVG.
Upon approval, the fifth condition determining means 208e determines that the fifth condition is satisfied.

(Step S10)
The discharger refers to the manifest information (see FIG. 4) of the waste treatment management server SVG via the discharger terminal C1 or the discharger terminal C2 (see FIG. 2) to determine the waste treatment status. I can confirm.

Next, the settlement system 50 (see FIG. 2) used by the waste treatment management system 10 will be described.
The payment system 50 is a system that uses a block chain network BC (see FIG. 2) including a block chain group BC1, a block chain BC2, and a block chain BC3 shown in FIG. 6, and the initial bill recorded on the block chain. If the amount is revised, you can settle with the revised billing amount.
The blockchain is preferably a consortium type blockchain in which a plurality of specified businesses can participate.

The block chain group BC1 is composed of a plurality of block chains BC1a, BC1b, BC1c, BC1d, BC1e, BC1f, and records information to be managed in the above-mentioned waste treatment management.
In each block chain, a block is generated and information is recorded for each case specified by the manifest number. When the information is modified, the modified information is added to each block.

The block chain BC1a (an example of a calculation reference registration block chain) has a manifest number for identifying a case, a unit price of waste processing cost (information included in the processing fee information stored in the storage unit 202, Information on the calculation criteria that affects the amount of money) and information on the deadline for billing will be recorded as a block for each case.
In the block chain BC1b, the first information (see FIG. 4) of the delivery confirmation information including the manifest number is recorded as a block for each case.

In the block chain BC1c, the manifest number for identifying a case and the second information of the delivery confirmation information (see FIG. 4) are recorded as a block for each case.
In the block chain BC1d (an example of a calculation standard registration block chain), the manifest number for identifying a case and the third information of the delivery confirmation information (see FIG. 4) are recorded as a block for each case.
The manifest information (see FIG. 4) is recorded as a block for each case in the block chain BC1e.
The updated manifest information updated in step S8 is recorded as a block for each case in the block chain BC1f.

In the block chain BC2 (an example of a billing amount accumulating block chain), a manifest number for identifying each case and a charge amount of the case are recorded. When the billed amount is modified, the revised billed amount is recorded for each block.
For example, in FIG. 6, the following contents are recorded in each block of the block chain BC2.
1. Block with block height #00001 (1) Manifest number that identifies the case 001 (2) Charge amount 7,000 yen for the case 001 Note that the charge amount 7,000 yen recorded in this block is the last closing date Has already been billed (processed) when has passed.
2. 2. Block with height #00002 (1) Manifest number that identifies case 002 (2) Charge amount of case 002 10,000 yen 3. 3. Block with height #00003 (1) Manifest number that identifies case 003 (2) Charge amount of case 003 6,000 yen 4. Block with height #00004 (1) Manifest number that identifies case 001 (2) Charge amount of case 001 10,000 yen 5. 5. Block with height #00005 (1) Manifest number that identifies the case 004 (2) Billing amount 8,000 yen for the case 004 6. Block with block height #00006 (1) Manifest number for identifying case 005 (2) Charge amount 5,000 yen for case 005 7. Block with block height #00007 (1) Manifest number that identifies case 006 (2) Charge amount of case 006 JPY 9,000 8. Block with block height #00008 (1) Manifest number that identifies case 002 (2) Charge amount 12,000 yen after modification of case 002 9. Block of block height #000009 (1) Manifest number that identifies case 001 (2) Charge amount 5,000 yen after modification of case 001

In the block chain BC3 (an example of a block chain for registering the transferred amount), the transferred amount is recorded for each case. The transferred amount is the liquidation amount when the billed amount is corrected. Further, the height (information for specifying the block) of the final block (the block generated last) of the block chain BC2 is recorded for each case.
For example, in FIG. 6, the following contents are recorded in each block of the block chain BC3.
1. Block with block height #00001 (1) Manifest number that identifies case 001 (2) Transfer amount 7,000 yen that has been transferred after the last closing date of case 001 (3) Blockchain BC2 at the time of the previous transfer Final block height for matter 001 #00001
2. Block height #00002 (1) Manifest number that identifies case 002 (2) Transfer amount of case 002 12,000 yen (3) Final block height for case 002 of block chain BC2 at the time of transfer # 00008
3. Block height #00003 (1) Manifest number that identifies the case 003 (2) Transfer amount of the case 003 JPY 6,000 (3) Height of the final block for the case 003 of the blockchain BC2 at the time of transfer # 0000 3
4. Block height #00004 (1) Manifest number that identifies the case 001 (2) Clearing amount of the case 001-2,000 yen (3) Height of the final block for the case 001 of the block chain BC2 at the time of transfer # 0000 9

The payment system 50 includes the waste processing management server SVG and the nodes N1 and N2 described above, and uses the block chain group BC1 and the block chains BC2 and BC3 described above.

As shown in FIG. 7, the waste treatment management server SVG has an estimation/contract information management means 220, a business consignment management means 222, a business performance management means 224, and the above-mentioned contract creation means 210.

The estimate/contract information management means 220 can manage information relating to the calculation standard of the billed amount or the estimated amount in the waste treatment. The quotation/contract information management unit 220 stores the information in the storage unit 202 (see FIG. 4) after obtaining the approval from the discharger when the information is registered or changed by the collection and transportation company.
The business consignment management means 222 (see FIG. 7) can manage the delivery confirmation information. The business consignment management means 222, like the quotation/contract information management means 220, stores the information after receiving approval from the discharge business operator when the information is registered or changed by the collection and transportation company. (See 4).
The work record management means 224 (see FIG. 7) can manage record information such as the actual amount of waste discharged. Similar to the estimate/contract information management unit 220, the business performance management unit 224 stores the information after receiving the approval from the discharge business operator when the information is registered or changed by the collection and transportation company. (See 4).

The contract creating means 210 can create the first to third smart contracts with predetermined conditions and predetermined contents.
The first smart contract is that the predetermined condition is that any one of the information recorded in the block chains BC1a to BC1f is modified in the storage unit 202 of the waste treatment management server SVG, and the predetermined condition is determined in advance. What is done is to record the modified information in the corresponding block chains BC1a to BC1f of the block chain group BC1. Note that in FIG. 6, the predetermined conditions and contents are described only for the block chain BC1a, and are omitted for the block chains BC1b to BC1f.
In the second smart contract, the predetermined condition is that the information is added to any of the block chains BC1a to BC1f and the predetermined condition is satisfied, and the predetermined content corresponds to the block chain BC2. It is to record the billed amount of the case.
The third smart contract is that the predetermined condition is that the billing deadline has passed, and the predetermined content is the charge amount or the charge amount for each case based on the recorded contents of the block chain BC2 and the block chain BC3. It is to calculate the settlement amount, and record the amount of money transferred successfully and the height of the final block relating to the transferred matter recorded in the block chain BC2. The predetermined condition is not limited to the expiration of the billing closing date, and may be any condition.

The nodes N1 and N2 are, for example, nodes operated by a collection and transportation company, a financial institution, or the like. The number of nodes is not limited to two, and may be a node operated by a pre-authorized storage company or disposal company, if necessary.

Next, a payment method by the payment system 50 will be described. It should be noted that, if possible, the steps shown below may be executed in reverse order or in parallel. Further, this payment method is realized by a payment program executed by a distributed computing system including a plurality of nodes.

(Step P1)
A block chain group BC1, a block chain BC2 and a block chain BC3 are constructed.

(Step P2)
The contract creating means 210 (see FIG. 7) creates the above-mentioned first to third smart contracts.

(Step P3)
In order for the collection and transportation company to revise the calculation standards (for example, information on the unit price of waste treatment cost and the amount of waste discharged by item) that affect the amount charged to the discharger (an example of the requestee) When the revised calculation standard is registered in the waste treatment management server SVG, the quotation/contract information management means 220, the business consignment management means 222 or the business performance management means 224 that manages the corresponding information prompts the emission business operator for approval. ..
When the discharger approves the correction of the information, the corresponding estimate/contract information management means 220, business consignment management means 222 or business performance management means 224 stores the corrected information in the storage means 202 (see FIG. 4). ..

(Step P4)
In the previous step P3, when the modified information is stored in the storage unit 202, the condition of the first smart contract is satisfied, and the modified information is registered for each block in the corresponding block chains BC1a to BC1f.
For example, when the unit price of the disposal cost of the waste stored in the storage unit 202 (an information included in the processing charge information stored in the storage unit 202, which is an example of a calculation standard affecting the billing amount) is corrected. , The condition of the first smart contract is satisfied, and the modified unit price (an example of the modified calculation standard) is recorded for each block in the block chain BC1a.
In addition, for example, when the discharge amount of each item of waste stored in the storage unit 202 (an example of a calculation standard that affects the billed amount) is corrected, the condition of the first smart contract is satisfied, and the corrected discharge is performed. The quantity (an example of the modified calculation standard) is recorded for each block in the block chain BC1d.
That is, each time the first smart contract modifies the calculation standard for the amount charged to the claimant, the modified calculation standard is converted to the block chain BC1a or the block chain BC1d (an example of the calculation standard registration block chain). It will be recorded as the revised calculation standard.
Since the modified calculation standard is recorded in the block chain by the first smart contract, the recording means for recording the modified calculation standard in the block chain is realized by the first smart contract.

(Step P5)
In the previous step P4, when information is recorded in any of the block chains BC1a to BC1f and the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billing amount of the corresponding case is recalculated, and the block chain The corrected billing amount is recorded for each block in BC2.
For example, when the unit price of the modified processing cost is recorded in the block chain BC1a, the condition of the second smart contract is satisfied, and the billed amount of the relevant case is recalculated based on the modified unit price of the processing cost. The corrected billing amount is recorded for each block in the block chain BC2.
That is, the modified billing amount calculated based on the modified calculation standard by the second smart contract is recorded in the billing amount accumulating block chain BC2 (an example of the billing amount accumulating block chain).

(Step P6)
When the deadline for billing has passed, the conditions for the third smart contract are met, and the remittance amount is calculated based on the recalculated billing amount and the height of the final block of the cleared case that is recorded in the blockchain BC2. Then, the transfer means (not shown) executes a process of transferring the amount of money for clearing.
That is, the third smart contract calculates and clears the settlement amount for clearing the billed amount based on the revised billed amount.
After that, when it is confirmed that the transfer is successful, the amount transferred to the block chain BC3 and the height of the final block of the cleared applicable case recorded in the block chain BC2 are recorded.

As described above, according to the settlement method by the settlement system 50, at least all the modified calculation standards affecting the billed amount are recorded in the blockchain, and the billed amount is settled based on the modified calculation standard recorded in the blockchain. Therefore, even if the blockchain, which is difficult to tamper (correct), is used, if the initial billing amount is revised, the revised billing amount can be settled.

Next, regarding the settlement method after step P3, the collecting and transporting company collects and transports the waste of wood (processing unit price 100 yen/kg) for the case 001 shown in FIG. 6, and discharges 7,000 yen for 70 kg. A description will be given of a specific example in the case where the user has made a mistake and has corrected the discharge amount in the situation where the payment has already been made, but the input amount of 100 kg was erroneously input, so that it was necessary to correct the discharge amount to the original 50 kg.
In this specific example, the closing date is the end of the month.

Since the collection and transportation company noticed that the discharge amount of 70 kg was incorrect for the billing of the last month, if the discharge amount information (third information of the delivery confirmation information) is corrected from 70 kg to 100 kg, the business performance management means 224 prompts the emission business operator for approval.
When the discharger approves the correction of the information, the job performance management means 224 stores the corrected information in the storage means 202 (step P3).

Then, since the third information of the delivery confirmation condition is corrected in the waste treatment management server SVG, the condition of the first smart contract is satisfied, and the corrected information on the amount of discharged wood (100 kg) is obtained. The included third information is recorded as the block BLCa in the block chain BC1d (step P4).

The information (100 kg) of the modified wood emission amount is recorded in the block chain BC1d, and when the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billed amount for the case 001 is the modified third value. The re-calculated amount of 10,000 yen is recorded on the block chain BC2 as a block of height #00004 after being recalculated based on the information of (step P5).
In the blockchain BC2, the block (height #00001) related to the matter 001 is recorded as the billed amount (processed) of the last month, and the block (height #00001) related to the matter 002 is recorded as the billed amount (unprocessed) of this month. (00002) and the block (height #00003) related to the case 003 are already recorded.

After that, when he noticed that the discharge amount of 100 kg was an erroneous input, and the collector/collector corrects the information on the discharge amount of the waste wood (the third information of the delivery confirmation information) from 100 kg to 50 kg, the business performance management means 224 prompts the emission business operator for approval.
When the discharger approves the correction of the information, the job performance management means 224 stores the corrected information in the storage means 202 (step P3).

Then, since the third information of the delivery confirmation condition is corrected in the waste treatment management server SVG, the condition of the first smart contract is satisfied, and the information of the amount of discharged wood (50 kg) after the correction is obtained. The included third information is recorded as the block BLCd in the block chain BC1d (step P4).
It is to be noted that, until the step P4 is executed, in the block chain BC1d, the block BLCa, the block BLCb regarding the case 002, and the block BLCc regarding the case 005 are sequentially recorded.

The information (50 kg) of the modified wood emission amount is recorded in the block chain BC1d, and when the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billing amount for the case 001 is modified to the third condition. The billing amount of 5,000 yen after recalculation based on the information is corrected and recorded in the block chain BC2 as a block of height #00009 (step P5).
By the time the step P5 is executed, the block chain BC2 has a block (height #00005) related to the case 004, a block (height #00006) related to the case 005, and a block (height #00006) related to the case 006. (00007) and a block (height #00008) related to the case 002 are sequentially added.

When the billing deadline has passed, the conditions of the third smart contract are satisfied, and the recalculated billing amount of 5,000 yen and the deposited billing amount of 7,000 yen (see the block of block #BC01 height #00001) The difference of -2,000 yen is calculated as the liquidation amount, and -2,000 yen is transferred to the claimant. That is, 2,000 yen is returned to the demandee (step P6).

Here, the calculation of the settlement amount is 1) the billed amounts recorded in the block heights #00001, #00004, and #00009 related to the case 001 of the block chain BC2, and 2) the case processed last month of the block chain BC3, respectively. It is performed based on the height #00001 of the final block (information indicating the processed block recorded in the block chain BC2) recorded in the block of height #00001 related to 001.

If the transfer is successful, the settlement amount of −2,000 yen transferred to the block chain BC3 is recorded. Further, the height #000009 of the last block of the case 001 recorded in the block chain BC2 is recorded and used in the next calculation of the settlement amount. That is, in the block height #00009 of the block chain BC3, the settlement amount of −2,000 yen and the block height #00009 are recorded.
As described above, in this specific example, since the original charge of 5,000 yen was billed at 7,000 yen, a process of returning the difference of 2,000 is performed.

As described above, according to the settlement method by the settlement system 50, it is possible to provide the transparency of the billing cost and the convenience that it can be corrected later.

Explaining from another perspective, the settlement system 50 records the modified calculation standard as the modified calculation standard in the calculation standard registration blockchain every time the calculation standard of the amount charged to the discharger is modified. And a clearing means for calculating and clearing a clearing amount for clearing the billed amount based on the revised calculation standard. Of the recording means and the settlement means, at least the recording means is realized by a smart contract created by the contract creating means included in the waste processing management server.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and changes in conditions and the like without departing from the gist are all within the scope of application of the present invention.
The settlement system (settlement method) is not applied to settlement of billing costs for waste disposal, but can be applied to settlement of billing costs for any treatment.

The waste treatment process includes, for example, as shown in FIG. 1, a discharge process P1, a collection and transportation process P2, a storage process P3, and a disposal process P4.
The discharge step P1 is a step in which, for example, a remodeling business operator (one example of a recycle business operator) who has received an order from a customer for a building remodeling business discharges the waste generated by the remodeling work. Here, this renovation business operator develops a business in a franchise format, and has a headquarters as a discharge business operator and a member store. However, the emission business may not be a franchise-type business and may be a single business. Therefore, hereinafter, the renovation company may be simply referred to as an “emission company” without distinguishing between the headquarters and the member stores.

The collecting and transporting step P2 is a step in which a collecting and transporting company collects and transports waste and transports it to a predetermined storage location.

The storage process P3 is a process in which the storage company stores the waste in the storage facility. Note that the storage company may be included in the above-mentioned collection/transportation company in the storage process P3, since a work of collecting and transporting waste may occur as necessary in this storage process P3.

The disposal process P4 is a process in which the disposal company disposes the waste. Note that the disposal company may be included in the above-mentioned collection/transportation company in the disposal process P4, since a work of collecting and transporting waste may occur as necessary in this disposal process P4.

Here, the Internet N is connected to an electronic manifest system (JWNET server SVJ) operated by the Japan Industrial Waste Treatment Promotion Center (hereinafter referred to as “information processing center”). That is, the information processing center (JWNET server SVJ) can be accessed from each of the discharge company terminals C1 and C2, the collection and transportation company terminal MD, and the waste processing management server SVG.

The discharge company terminals C1 and C2 are terminals operated by the above-mentioned reform company. The discharging company terminal C1 and the discharging company terminal C2 are, for example, computers installed at the locations of the headquarters and member stores, respectively.
In the waste treatment management system 10, the member store may perform the operation or work performed by the head office instead, or the head office may perform the operation or work performed by the member store instead.

The collection and transportation company terminal MD is a terminal operated by the collection and transportation company, and is, for example, a mobile terminal carried by a person in charge of the collection and transportation company. This mobile terminal has a camera and a GPS function.
The collection and transportation company terminal MD may be any computer as long as it can be connected to the Internet N, and may be a computer installed at the location of the collection and transportation company. Further, a plurality of collection/transportation carrier terminals MD may exist for one collection/transportation carrier.

The waste treatment management server SVG is a server operated by a management company that manages the treatment of waste.
As shown in FIG. 3, the waste treatment management server SVG includes a storage unit 202, a trader selection unit 203, a delivery confirmation information transmission unit 204, a position information confirmation unit 205, an update unit 206, and first to fifth condition determination units. It has 208a to 208e and a contract creating means 210.
Each of these means is realized by the waste treatment management server SVG by a program executed by the waste treatment management server SVG.

The storage unit 202 has, for example, a hard disk drive device, and as shown in FIG. 4, can store delivery confirmation information, temporary registration information, a database of collection and transportation companies, processing fee information, and transportation destination location information.
The delivery confirmation information includes at least information described on the delivery confirmation slip in the electronic manifest system, and includes first information, second information, and third information.

The first information is information provided by the waste discharger accessing the waste treatment management server SVG. For example, the manifest number, the customer name (reform requester name), the zip code of the customer's house, and the waste. Address of the customer's house (collection location of waste), delivery construction slip number, planned discharge date, work process date, remodeling type, registration cooperation company (substantially based on the request of the remodeling company) It includes information on the renovation company that performs building renovation work, collection conditions, and waste emission forecasts. The collection condition is information such as the type of collection vehicle, the presence/absence of special collection that needs to be carried out or carried by two people, and the planned discharge amount of waste.
The second information is information provided by the trader selection means 203 or the management company, which will be described later, and is, for example, the name and location of the collection and transportation company.
The third information is information provided by the collection and transportation company accessing the waste treatment management server SVG. For example, the date of delivery, the discharge amount of each waste item, the packing form, and the waste amount. Information such as the location of the transportation destination (disposal site, etc.), waste disposal method, vehicle number, vehicle name, etc.

The temporary registration information is at least information including manifest information and information of a plurality of photographs with position information including position information of the shooting location where the waste was shot.
The manifest information is information registered in the electronic manifest system, and is configured based on the delivery confirmation information.
The plurality of photographs with position information are a photograph P1 of waste taken by the collection and transportation company at the collection destination and a photograph P2 of waste taken at the transportation destination, respectively. The position information of the shooting location acquired using GPS is associated with each of the photographs P1 and P2.

The collection and transportation company database is a database in which a plurality of collection and transportation companies are registered. Information (names, locations, etc.) of a plurality of collection and transportation companies is registered in this database. In addition, each collection and transportation company registered in this database is a highly reliable company that has been examined by the management company to meet predetermined criteria.

The processing fee information is information on the fee for processing the waste set by each of the plurality of collection and transportation companies. The treatment fee is set by each collection and transportation company accessing the waste treatment management server SVG.
The processing fee consists of collection and transportation costs, disposal costs, industrial waste tax, and additional fees (costs such as the distance to the waste collection destination and the burden of loading work).

The transportation destination location information is information on the location of the transportation destination where the collection and transportation company transports the waste, and is preset by the management company. The location of the transportation destination is, for example, the location of the disposal site.

The trader selection means 203 processes the waste based on the location of the collection destination of the waste (address of the customer's house), the location of the collection transporter, and the processing fee information of each collection transporter stored in the storage means 202. You can calculate the charge and select the collection and transportation company with the lowest processing charge.

The delivery confirmation information transmitting means 204 can transmit the delivery confirmation information to the collection and transportation company terminal MD via the Internet N.

The position information confirmation unit 205 detects that the position included in the information of the photo P1 is within a preset distance range from the information of the location of the collection destination, and the position included in the information of the photo P2 is from the information of the location of the transportation destination. It can be confirmed that the distance is within the preset distance. The range of this distance is stored in the storage unit 202.

The update unit 206 can update the manifest information stored in the storage unit 202 based on the latest manifest information registered in the electronic manifest system. The updating unit 206 can update the manifest information for each predetermined period.

The first condition is that the position included in the information of the photo P1 is within a preset distance from the information of the location of the collection destination included in the delivery confirmation information, and the position included in the information of the photo P2 is That is, it is within the range of a preset distance from the delivery confirmation information or the location information of the delivery destination included in the delivery destination location information.
Therefore, when the above-mentioned position information confirmation means 205 confirms that the position information associated with the photographs P1 and P2 of the waste is within the range of the preset distance from the locations of the collection destination and the transportation destination, respectively. The first condition determination unit 208a determines that the first condition is satisfied.

The second condition determining means 208b can determine whether the second condition is satisfied. The second condition is that the amount of waste obtained from each of the photographs P1 and P2 and the amount of waste input by the collection and transportation company via the terminal of the collection and transportation company match. It should be noted that the term “match” here does not mean a match in a strict sense. That is, “match” means “substantial match” in which a predetermined degree of mismatch is allowed (hereinafter the same).
The amount of waste is obtained from each of the photographs P1 and P2 by using, for example, AR (Augmented Reality).

The third condition determining unit 208c can determine whether the third condition is satisfied. The third condition is that the waste recorded in the photo P1 and the waste recorded in the photo P2 are the same as the type of waste input by the collection and transportation company via the terminal of the collection and transportation company. is there. It should be noted that the term “identical” here does not mean the same in a strict sense. That is, “identical” means “substantially identical” in which a predetermined degree of disparity is allowed (hereinafter, the same).
The types of the waste recorded in the photograph P1 and the waste recorded in the photograph P2 are obtained by image processing using, for example, AI (Artificial Intelligence).

The fourth condition determining means 208d can determine whether or not the fourth condition is satisfied. The fourth condition is that the manifest information configured based on the delivery confirmation information is main-registered in the electronic manifest system.

The fifth condition determining means 208e can determine whether the fifth condition is satisfied. The fifth condition is that the discharge business operator or the management business operator approves the collection and transportation company to execute the settlement process.
The fifth condition determining unit 208e monitors that the discharging business operator or the management business company approves the execution of the settlement process, and when the approval is made, determines that the fifth condition is satisfied.

The contract creating means 210 can create a smart contract for the block chains BC1a, BC1b, BC1c, BC1d, BC1e, BC2, and BC3 that have been built in advance.
The contract creating means 210 will be described later.

Next, a waste treatment management method using the waste treatment management system 10 (excluding settlement processing for a collection and transportation company) will be described with reference to FIG. It should be noted that, if possible, the steps shown below may be executed in reverse order or in parallel.

(Step S1)
The discharging company (headquarters or member store) acquires the manifest number in the electronic manifest. The manifest number can be obtained by utilizing the reservation registration provided by the information processing center.
On the other hand, the contract creating unit 210 creates a contract (smart contract) having predetermined conditions and predetermined contents for waste processing corresponding to the acquired manifest number. The specific contents of the smart contract will be described later.
The contract does not have to be created in step S1 and may be created in step S2, step S3, or step S4. The created contract will be registered in the blockchain at an appropriate timing.

(Step S2)
The discharger receives an order from a customer for renovation work. When the details of the reform work are clarified and it is determined that the waste generated by this reform work needs to be treated, the discharge business operator (member store) uses the discharge business operator terminal C2 (see FIG. 2). Then, the first information (see FIG. 4) other than the manifest number included in the delivery confirmation information is registered in the waste processing management server SVG.
The waste management is started by the registration of the first information included in the delivery confirmation information.

(Step S3)

The company selection means 203 (see FIG. 3) of the waste treatment management server SVG selects a collection and transportation company.
In this step S3, the management company manually confirms the delivery confirmation information (see FIG. 4), and based on the delivery confirmation information, it is appropriate for the collection and transportation of the waste from a plurality of collection and transportation companies. You may choose a different collection and transportation company.
Thereafter, the selected collection hauler is arranged.
In addition, since the second information included in the delivery confirmation information is confirmed by this step, the management company registers the second information in the waste treatment management server SVG (see FIG. 2).

(Step S4)
The selected collection and transportation company acquires and confirms the delivery confirmation information stored in the storage means 202 (see FIG. 3) of the waste treatment management server SVG. In detail, the delivery confirmation information transmitting means 204 (see FIG. 3) of the waste treatment management server SVG transmits the delivery confirmation information (see FIG. 4) based on the request from the collection and transportation company.
Next, the collection and transportation company transmits the acquired delivery confirmation information to a remodeling company (a company that substantially carries out the remodeling work of the building based on the request of the remodeling business operator) by using, for example, FAX. The reformer who received the FAX confirms the delivery confirmation information and, for example, when there is a change in the scheduled discharge date, notifies the collection and transportation company of the change.

Next, when the renovation work is performed by the renovation company and the waste is discharged, the collection and transportation company goes to the waste discharge site on the scheduled discharge date included in the delivery confirmation information and collects the waste.
At the waste collection site (collection destination), the collection and transportation company photographs the discharged waste P1 using the collection and transportation company terminal MD (see FIG. 2). This photograph P1 includes the position information acquired at the time of photographing by GPS. After transporting the collected waste, the collection and transportation company uses the collection and transportation company terminal MD to take a picture P2 of the waste at the disposal site of the transportation destination. This photograph P2 also includes the position information acquired at the time of photographing by GPS.
After that, the collection and transportation company uses the collection and transportation company terminal MD to discharge the discharge amount of each waste item and the third information and photographs P1 and P2 included in the delivery confirmation information of the waste and the like (Fig. 4). (Refer) to the waste treatment management server SVG for registration.

The timing of transmitting the third information included in the delivery confirmation information and the photographs P1 and P2 may be arbitrary, and may be sequentially transmitted instead of being transmitted collectively.
Further, when the collection and transportation company terminal MD (see FIG. 2) is a computer installed at the location of the collection and transportation company, the third information and the photographs P1 and P2 may be transmitted using this computer. ..
In this way, the photographs P1 and P2 of the waste with location information taken by the collection and transportation company at the collection destination and the transportation destination are registered, so that the collection and transportation company does not actually carry the waste. Nevertheless, the fraudulent appearance of being transported is suppressed and the process of processing industrial waste is made transparent.

(Step S5)
The first to third condition determining means 208a to 208c respectively determine the success or failure of the first to third conditions based on the third information and the photographs P1 and P2 transmitted from the collection and transportation company terminal MD.
When the first to third condition determining means 208a to 208c determine that the first to third conditions are satisfied, the next step S6 is executed.

(Step S6)
The management company main-registers the manifest information included in the temporary registration information in the electronic manifest system. At that time, the management company transmits the manifest information to the electronic manifest system by the EDI method.
When the manifest information is main-registered, the fourth condition determining means 208d determines that the fourth condition is satisfied, and the next step S7 is executed.

(Step S7)
Each collection and transportation company reports to the electronic manifest system that the transportation of waste has been completed.
Specifically, the collection and transportation company directly accesses the JWNET server SVJ and registers the collection date and the disposal completion date of the waste by using the Web method. Since the commonly used Web method is used for registration, the collection and transportation company can report that the transportation of waste has been completed without hesitation about the operation method.
If a change is required, the fixed quantity of waste is also registered.

However, the waste collection date and the disposal completion date registered in step S7 can be registered in the previous step S6. That is, when the management company knows the waste collection date and the disposal completion date before step S6 is executed, the management company uses the EDI method to collect the waste collection date and the waste information together with the manifest information. The disposal completion date may be registered in the JWNET server SJ. When the collection date and the disposal completion date of the waste are registered in the previous step S6, the execution of this step S7 is omitted and the next step S8 is executed.

(Step S8)
The updating unit 206 (see FIG. 3) of the waste processing management server SVG updates the manifest information stored in the storage unit 202 based on the latest manifest information registered in the electronic manifest system. The update is executed every predetermined period.

(Step S9)
The discharger confirms the temporary registration information (manifest information and photographs P1 and P2) registered in the waste treatment management server SVG in step S4. If there is no problem in the temporary registration information, the discharger approves the collection and transportation company to execute the settlement process on the waste treatment management server SVG.
Upon approval, the fifth condition determining means 208e determines that the fifth condition is satisfied.

(Step S10)
The discharger refers to the manifest information (see FIG. 4) of the waste treatment management server SVG via the discharger terminal C1 or the discharger terminal C2 (see FIG. 2) to determine the waste treatment status. I can confirm.

Next, the settlement system 50 (see FIG. 2) used by the waste treatment management system 10 will be described.
The payment system 50 is a system that uses a block chain network BC (see FIG. 2) including a block chain group BC1, a block chain BC2, and a block chain BC3 shown in FIG. 6, and the initial bill recorded on the block chain. If the amount is revised, you can settle with the revised billing amount.
The blockchain is preferably a consortium type blockchain in which a plurality of specified businesses can participate.

The block chain group BC1 is composed of a plurality of block chains BC1a, BC1b, BC1c, BC1d, BC1e, BC1f, and records information to be managed in the above-mentioned waste treatment management.
In each block chain, a block is generated and information is recorded for each case specified by the manifest number. When the information is modified, the modified information is added to each block.

The block chain BC1a (an example of a calculation reference registration block chain) has a manifest number for identifying a case, a unit price of waste processing cost (information included in the processing fee information stored in the storage unit 202, Information on the calculation criteria that affects the amount of money) and information on the deadline for billing will be recorded as a block for each case.
In the block chain BC1b, the first information (see FIG. 4) of the delivery confirmation information including the manifest number is recorded as a block for each case.

In the block chain BC1c, the manifest number for identifying a case and the second information of the delivery confirmation information (see FIG. 4) are recorded as a block for each case.
In the block chain BC1d (an example of a calculation standard registration block chain), the manifest number for identifying a case and the third information of the delivery confirmation information (see FIG. 4) are recorded as a block for each case.
The manifest information (see FIG. 4) is recorded as a block for each case in the block chain BC1e.
The updated manifest information updated in step S8 is recorded as a block for each case in the block chain BC1f.

In the block chain BC2 (an example of a billing amount accumulating block chain), a manifest number for identifying each case and a charge amount of the case are recorded. When the billed amount is modified, the revised billed amount is recorded for each block.
For example, in FIG. 6, the following contents are recorded in each block of the block chain BC2.
1. Block with block height #00001 (1) Manifest number that identifies the case 001 (2) Charge amount 7,000 yen for the case 001 Note that the charge amount 7,000 yen recorded in this block is the last closing date Has already been billed (processed) when has passed.
2. 2. Block with height #00002 (1) Manifest number that identifies case 002 (2) Charge amount of case 002 10,000 yen 3. 3. Block with height #00003 (1) Manifest number that identifies case 003 (2) Charge amount of case 003 6,000 yen 4. Block with height #00004 (1) Manifest number that identifies case 001 (2) Charge amount of case 001 10,000 yen 5. 5. Block with height #00005 (1) Manifest number that identifies the case 004 (2) Billing amount 8,000 yen for the case 004 6. Block with block height #00006 (1) Manifest number for identifying case 005 (2) Charge amount 5,000 yen for case 005 7. Block with block height #00007 (1) Manifest number that identifies case 006 (2) Charge amount of case 006 9,000 yen Block with block height #00008 (1) Manifest number that identifies case 002 (2) Charge amount 12,000 yen after modification of case 002 9. Block of block height #000009 (1) Manifest number that identifies case 001 (2) Charge amount 5,000 yen after modification of case 001

In the block chain BC3 (an example of a block chain for registered transfer amount), the transferred amount is recorded for each case. This transferred amount is the liquidation amount if the billed amount is corrected. Further, the height (information for identifying the block) of the final block (the block generated last) of the block chain BC2 is recorded for each case.
For example, in FIG. 6, the following contents are recorded in each block of the block chain BC3.
1. Block with block height #00001 (1) Manifest number that identifies case 001 (2) Transfer amount 7,000 yen that has been transferred after the last closing date of case 001 (3) Blockchain BC2 at the time of the previous transfer Final block height for matter 001 #00001
2. Block height #00002 (1) Manifest number that identifies case 002 (2) Transfer amount of case 002 12,000 yen (3) Final block height for case 002 of block chain BC2 at the time of transfer # 00008
3. Block height #00003 (1) Manifest number that identifies case 003 (2) Transfer amount 6,000 yen for case 003 (3) Height of final block for case 003 in block chain BC2 at the time of transfer # 0000 3
4. Block height #00004 (1) Manifest number that identifies case 001 (2) Clearing amount of case 001-2,000 yen (3) Height of final block for case 001 of block chain BC2 at the time of transfer # 0000 9

The payment system 50 includes the waste processing management server SVG and the nodes N1 and N2 described above, and uses the block chain group BC1 and the block chains BC2 and BC3 described above.

As shown in FIG. 7, the waste treatment management server SVG has an estimation/contract information management means 220, a business consignment management means 222, a business performance management means 224, and the above-mentioned contract creation means 210.

The estimate/contract information management means 220 can manage information relating to the calculation standard of the billed amount or the estimated amount in the waste treatment. The quotation/contract information management unit 220 stores the information in the storage unit 202 (see FIG. 4) after obtaining the approval from the discharger when the information is registered or changed by the collection and transportation company.
The business consignment management means 222 (see FIG. 7) can manage the delivery confirmation information. The business consignment management means 222, like the quotation/contract information management means 220, stores the information after receiving approval from the discharge business operator when the information is registered or changed by the collection and transportation company. (See 4).
The work record management means 224 (see FIG. 7) can manage record information such as the actual amount of waste discharged. Similar to the estimate/contract information management unit 220, the business performance management unit 224 stores the information after receiving the approval from the discharge business operator when the information is registered or changed by the collection and transportation company. (See 4).

The contract creating means 210 can create the first to third smart contracts with predetermined conditions and predetermined contents.
The first smart contract is that the predetermined condition is that any one of the information recorded in the block chains BC1a to BC1f is modified in the storage unit 202 of the waste treatment management server SVG, and the predetermined condition is determined in advance. What is done is to record the modified information in the corresponding block chains BC1a to BC1f of the block chain group BC1. Note that in FIG. 6, the predetermined conditions and contents are described only for the block chain BC1a, and are omitted for the block chains BC1b to BC1f.
In the second smart contract, the predetermined condition is that the information is added to any of the block chains BC1a to BC1f and the predetermined condition is satisfied, and the predetermined content corresponds to the block chain BC2. It is to record the billed amount of the case.
The third smart contract is that the predetermined condition is that the billing deadline has passed, and the predetermined content is the charge amount or the charge amount for each case based on the recorded contents of the block chain BC2 and the block chain BC3. It is to calculate the settlement amount, and record the amount of money transferred successfully and the height of the final block relating to the transferred matter recorded in the block chain BC2. The predetermined condition is not limited to the expiration of the billing closing date, and may be any condition.

The nodes N1 and N2 are, for example, nodes operated by a collection and transportation company, a financial institution, or the like. The number of nodes is not limited to two, and may be a node operated by a pre-authorized storage company or disposal company, if necessary.

Next, a payment method by the payment system 50 will be described. It should be noted that, if possible, the steps shown below may be executed in reverse order or in parallel. Further, this payment method is realized by a payment program executed by a distributed computing system including a plurality of nodes.

(Step P1)
A block chain group BC1, a block chain BC2 and a block chain BC3 are constructed.

(Step P2)
The contract creating means 210 (see FIG. 7) creates the above-mentioned first to third smart contracts.

(Step P3)
In order for the collection and transportation company to revise the calculation standards (for example, information on the unit price of waste treatment cost and the amount of waste discharged by item) that affect the amount charged to the discharger (an example of the requestee) When the revised calculation standard is registered in the waste treatment management server SVG, the quotation/contract information management means 220, the business consignment management means 222 or the business performance management means 224 that manages the corresponding information prompts the emission business operator for approval. ..
When the discharger approves the correction of the information, the corresponding estimate/contract information management means 220, business consignment management means 222 or business performance management means 224 stores the corrected information in the storage means 202 (see FIG. 4). ..

(Step P4)
In the previous step P3, when the modified information is stored in the storage unit 202, the condition of the first smart contract is satisfied, and the modified information is registered for each block in the corresponding block chains BC1a to BC1f.
For example, when the unit price of the disposal cost of the waste stored in the storage unit 202 (an information included in the processing charge information stored in the storage unit 202, which is an example of a calculation standard affecting the billing amount) is corrected. , The condition of the first smart contract is satisfied, and the modified unit price (an example of the modified calculation standard) is recorded for each block in the block chain BC1a.
In addition, for example, when the discharge amount of each item of waste stored in the storage unit 202 (an example of a calculation standard that affects the billed amount) is corrected, the condition of the first smart contract is satisfied, and the corrected discharge is performed. The quantity (an example of the modified calculation standard) is recorded for each block in the block chain BC1d.
That is, each time the first smart contract modifies the calculation standard for the amount charged to the claimant, the modified calculation standard is converted to the block chain BC1a or the block chain BC1d (an example of the calculation standard registration block chain). It will be recorded as the revised calculation standard.
Since the modified calculation standard is recorded in the block chain by the first smart contract, the recording means for recording the modified calculation standard in the block chain is realized by the first smart contract.

(Step P5)
In the previous step P4, when information is recorded in any of the block chains BC1a to BC1f and the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billing amount of the corresponding case is recalculated, and the block chain The corrected billing amount is recorded for each block in BC2.
For example, when the unit price of the modified processing cost is recorded in the block chain BC1a, the condition of the second smart contract is satisfied, and the billed amount of the relevant case is recalculated based on the modified unit price of the processing cost. The corrected billing amount is recorded for each block in the block chain BC2.
That is, the modified billing amount calculated based on the modified calculation standard by the second smart contract is recorded in the billing amount accumulating block chain BC2 (an example of the billing amount accumulating block chain).

(Step P6)
When the deadline for billing has passed, the conditions for the third smart contract are met, and the remittance amount is calculated based on the recalculated billing amount and the height of the final block of the cleared case that is recorded in the blockchain BC2. Then, the transfer means (not shown) executes a process of transferring the amount of money for clearing.
That is, the third smart contract calculates and clears the settlement amount for clearing the billed amount based on the revised billed amount.
After that, when it is confirmed that the transfer is successful, the amount transferred to the block chain BC3 and the height of the final block of the cleared applicable case recorded in the block chain BC2 are recorded.

As described above, according to the settlement method by the settlement system 50, at least all the modified calculation standards affecting the billed amount are recorded in the blockchain, and the billed amount is settled based on the modified calculation standard recorded in the blockchain. Therefore, even if the blockchain, which is difficult to tamper (correct), is used, if the initial billing amount is revised, the revised billing amount can be settled.

Next, regarding the settlement method after step P3, the collecting and transporting company collects and transports the waste of wood (processing unit price 100 yen/kg) for the case 001 shown in FIG. 6, and discharges 7,000 yen for 70 kg. A description will be given of a specific example in the case where the user has made a mistake and has corrected the discharge amount in the situation where the payment has already been made, but the input amount of 100 kg was erroneously input, so that the original correction amount of 50 kg was required.
In this specific example, the closing date is the end of the month.

Since the collection and transportation company noticed that the discharge amount of 70 kg was incorrect for the billing of the last month, if the discharge amount information (third information of the delivery confirmation information) is corrected from 70 kg to 100 kg, the business performance management means 224 prompts the emission business operator for approval.
When the discharger approves the correction of the information, the job performance management means 224 stores the corrected information in the storage means 202 (step P3).

Then, since the third information of the delivery confirmation condition is corrected in the waste treatment management server SVG, the condition of the first smart contract is satisfied, and the corrected information on the amount of discharged wood (100 kg) is obtained. The included third information is recorded as the block BLCa in the block chain BC1d (step P4).

The information (100 kg) of the modified wood emission amount is recorded in the block chain BC1d, and when the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billed amount for the case 001 is the modified third value. The re-calculated amount of 10,000 yen is recorded on the block chain BC2 as a block of height #00004 after being recalculated based on the information of (step P5).
In the blockchain BC2, the block (height #00001) related to the matter 001 is recorded as the billed amount (processed) of the last month, and the block (height #00001) related to the matter 002 is recorded as the billed amount (unprocessed) of this month. (00002) and the block (height #00003) related to the case 003 are already recorded.

After that, when he noticed that the discharge amount of 100 kg was an erroneous input, and the collector/collector corrects the information on the discharge amount of the waste wood (the third information of the delivery confirmation information) from 100 kg to 50 kg, the business performance management means 224 prompts the emission business operator for approval.
When the discharger approves the correction of the information, the job performance management means 224 stores the corrected information in the storage means 202 (step P3).

Then, since the third information of the delivery confirmation condition is corrected in the waste treatment management server SVG, the condition of the first smart contract is satisfied, and the information of the amount of discharged wood (50 kg) after the correction is obtained. The included third information is recorded as the block BLCd in the block chain BC1d (step P4).
It is to be noted that, until the step P4 is executed, in the block chain BC1d, the block BLCa, the block BLCb regarding the case 002, and the block BLCc regarding the case 005 are sequentially recorded.

The information (50 kg) of the modified wood emission amount is recorded in the block chain BC1d, and when the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billing amount for the case 001 is modified to the third condition. The billing amount of 5,000 yen after recalculation based on the information is corrected and recorded in the block chain BC2 as a block of height #00009 (step P5).
By the time the step P5 is executed, the block chain BC2 has a block (height #00005) related to the case 004, a block (height #00006) related to the case 005, and a block (height #00006) related to the case 006. (00007) and a block (height #00008) related to the case 002 are sequentially added.

When the billing deadline has passed, the conditions of the third smart contract are satisfied, and the recalculated billing amount of 5,000 yen and the deposited billing amount of 7,000 yen (see the block of block #BC01 height #00001) The difference of -2,000 yen is calculated as the liquidation amount, and -2,000 yen is transferred to the claimant. That is, 2,000 yen is returned to the demandee (step P6).

Here, the calculation of the settlement amount is 1) the billed amounts recorded in the block heights #00001, #00004, and #00009 related to the case 001 of the block chain BC2, and 2) the case processed last month of the block chain BC3, respectively. It is performed based on the height #00001 of the final block (information indicating the processed block recorded in the block chain BC2) recorded in the block of height #00001 related to 001.

If the transfer is successful, the settlement amount of −2,000 yen transferred to the block chain BC3 is recorded. Further, the height #000009 of the last block of the case 001 recorded in the block chain BC2 is recorded and used in the next calculation of the settlement amount. That is, in the block height #00009 of the block chain BC3, the settlement amount of −2,000 yen and the block height #00009 are recorded.
As described above, in this specific example, since the original charge of 5,000 yen was billed at 7,000 yen, a process of returning the difference of 2,000 is performed.

As described above, according to the settlement method by the settlement system 50, it is possible to provide the transparency of the billing cost and the convenience that it can be corrected later.

Explaining from another perspective, the settlement system 50 records the modified calculation standard as the modified calculation standard in the calculation standard registration blockchain every time the calculation standard of the amount charged to the discharger is modified. And a clearing means for calculating and clearing a clearing amount for clearing the billed amount based on the revised calculation standard. Of the recording means and the settlement means, at least the recording means is realized by a smart contract created by the contract creating means included in the waste processing management server.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and changes in conditions and the like without departing from the gist are all within the scope of application of the present invention.
The settlement system (settlement method) is not applied to settlement of billing costs for waste disposal, but can be applied to settlement of billing costs for any treatment.

The waste treatment process includes, for example, as shown in FIG. 1, a discharge process P1, a collection and transportation process P2, a storage process P3, and a disposal process P4.
The discharge step P1 is a step in which, for example, a remodeling business operator (one example of a recycle business operator) who has received an order from a customer for a building remodeling business discharges the waste generated by the remodeling work. Here, this renovation business operator develops a business in a franchise format, and has a headquarters as a discharge business operator and a member store. However, the emission business may not be a franchise-type business and may be a single business. Therefore, hereinafter, the renovation company may be simply referred to as an “emission company” without distinguishing between the headquarters and the member stores.

The collecting and transporting step P2 is a step in which a collecting and transporting company collects and transports waste and transports it to a predetermined storage location.

The storage process P3 is a process in which the storage company stores the waste in the storage facility. Note that the storage company may be included in the above-mentioned collection/transportation company in the storage process P3, since a work of collecting and transporting waste may occur as necessary in this storage process P3.

The disposal process P4 is a process in which the disposal company disposes the waste.

In addition, each collection and transportation company registered in this database is a highly reliable company that has been examined by the management company to meet predetermined criteria.

The processing fee information is information on the fee for processing the waste set by each of the plurality of collection and transportation companies. The treatment fee is set by each collection and transportation company accessing the waste treatment management server SVG.
The processing fee consists of collection and transportation costs, disposal costs, industrial waste tax, and additional fees (costs such as the distance to the waste collection destination and the burden of loading work).

The transportation destination location information is information on the location of the transportation destination where the collection and transportation company transports the waste, and is preset by the management company. The location of the transportation destination is, for example, the location of the disposal site.

The trader selection means 203 processes the waste based on the location of the collection destination of the waste (address of the customer's house), the location of the collection transporter, and the processing fee information of each collection transporter stored in the storage means 202. You can calculate the charge and select the collection and transportation company with the lowest processing charge.

The delivery confirmation information transmitting means 204 can transmit the delivery confirmation information to the collection and transportation company terminal MD via the Internet N.

The position information confirmation unit 205 detects that the position included in the information of the photo P1 is within a preset distance range from the information of the location of the collection destination, and the position included in the information of the photo P2 is from the information of the location of the transportation destination. It can be confirmed that the distance is within the preset distance. The range of this distance is stored in the storage unit 202.

The update unit 206 can update the manifest information stored in the storage unit 202 based on the latest manifest information registered in the electronic manifest system. The updating unit 206 can update the manifest information for each predetermined period.

The first condition judging means 208a can judge whether the first condition is satisfied. The first condition is that the position included in the information of the photo P1 is within a preset distance from the information of the location of the collection destination included in the delivery confirmation information, and the position included in the information of the photo P2 is That is, it is within the range of a preset distance from the delivery confirmation information or the location information of the delivery destination included in the delivery destination location information.
Therefore, when the above-mentioned position information confirmation means 205 confirms that the position information associated with the photographs P1 and P2 of the waste is within the range of the preset distance from the locations of the collection destination and the transportation destination, respectively. The first condition determination unit 208a determines that the first condition is satisfied.

The second condition determining means 208b can determine whether the second condition is satisfied. The second condition is that the amount of waste obtained from each of the photographs P1 and P2 and the amount of waste input by the collection and transportation company via the terminal of the collection and transportation company match. It should be noted that the term “match” here does not mean a match in a strict sense. That is, “match” means “substantial match” in which a predetermined degree of mismatch is allowed (hereinafter the same).
The amount of waste is obtained from each of the photographs P1 and P2 by using, for example, AR (Augmented Reality).

The third condition determining unit 208c can determine whether the third condition is satisfied. The third condition is that the waste recorded in the photo P1 and the waste recorded in the photo P2 are the same as the type of waste input by the collection and transportation company via the terminal of the collection and transportation company. is there. It should be noted that the term “identical” here does not mean the same in a strict sense. That is, “identical” means “substantially identical” in which a predetermined degree of disparity is allowed (hereinafter, the same).
The types of the waste recorded in the photograph P1 and the waste recorded in the photograph P2 are obtained by image processing using, for example, AI (Artificial Intelligence).

The fourth condition determining means 208d can determine whether or not the fourth condition is satisfied. The fourth condition is that the manifest information configured based on the delivery confirmation information is main-registered in the electronic manifest system.
The fourth condition determining unit 208d monitors that the manifest information is main-registered in the electronic manifest system, and determines that the fourth condition is satisfied when the main registration is performed.

The fifth condition determining means 208e can determine whether the fifth condition is satisfied. The fifth condition is that the discharge business operator or the management business operator approves the collection and transportation company to execute the settlement process.
The fifth condition determining unit 208e monitors that the discharging business operator or the management business company approves the execution of the settlement process, and when the approval is made, determines that the fifth condition is satisfied.

The contract creating means 210 can create a smart contract for the block chains BC1a, BC1b, BC1c, BC1d, BC1e, BC2, and BC3 that have been built in advance.
The contract creating means 210 will be described later.

Next, a waste treatment management method using the waste treatment management system 10 (excluding settlement processing for a collection and transportation company) will be described with reference to FIG. It should be noted that, if possible, the steps shown below may be executed in reverse order or in parallel.

(Step S1)
The discharging company (headquarters or member store) acquires the manifest number in the electronic manifest. The manifest number can be obtained by utilizing the reservation registration provided by the information processing center.
On the other hand, the contract creating unit 210 creates a contract (smart contract) having predetermined conditions and predetermined contents for waste processing corresponding to the acquired manifest number. The specific contents of the smart contract will be described later.
The contract does not have to be created in step S1 and may be created in step S2, step S3, or step S4. The created contract will be registered in the blockchain at an appropriate timing.

(Step S2)
The discharger receives an order from a customer for renovation work. When the details of the reform work are clarified and it is determined that the waste generated by this reform work needs to be treated, the discharge business operator (member store) uses the discharge business operator terminal C2 (see FIG. 2). Then, the first information (see FIG. 4) other than the manifest number included in the delivery confirmation information is registered in the waste processing management server SVG.
The waste management is started by the registration of the first information included in the delivery confirmation information.

(Step S3)

The company selection means 203 (see FIG. 3) of the waste treatment management server SVG selects a collection and transportation company.
In this step S3, the management company manually confirms the delivery confirmation information (see FIG. 4), and based on the delivery confirmation information, it is appropriate for the collection and transportation of the waste from a plurality of collection and transportation companies. You may choose a different collection and transportation company.
Thereafter, the selected collection hauler is arranged.
In addition, since the second information included in the delivery confirmation information is confirmed by this step, the management company registers the second information in the waste treatment management server SVG (see FIG. 2).

(Step S4)
The selected collection and transportation company acquires and confirms the delivery confirmation information stored in the storage means 202 (see FIG. 3) of the waste treatment management server SVG. In detail, the delivery confirmation information transmitting means 204 (see FIG. 3) of the waste treatment management server SVG transmits the delivery confirmation information (see FIG. 4) based on the request from the collection and transportation company.
Next, the collection and transportation company transmits the acquired delivery confirmation information to a remodeling company (a company that substantially carries out the remodeling work of the building based on the request of the remodeling business operator) by using, for example, FAX. The reformer who received the FAX confirms the delivery confirmation information and, for example, when there is a change in the scheduled discharge date, notifies the collection and transportation company of the change.

Next, when the renovation work is performed by the renovation company and the waste is discharged, the collection and transportation company goes to the waste discharge site on the scheduled discharge date included in the delivery confirmation information and collects the waste.
At the waste collection site (collection destination), the collection and transportation company photographs the discharged waste P1 using the collection and transportation company terminal MD (see FIG. 2). This photograph P1 includes the position information acquired at the time of photographing by GPS. After transporting the collected waste, the collection and transportation company uses the collection and transportation company terminal MD to take a picture P2 of the waste at the disposal site of the transportation destination. This photograph P2 also includes the position information acquired at the time of photographing by GPS.
After that, the collection and transportation company uses the collection and transportation company terminal MD to discharge the discharge amount of each waste item and the third information and photographs P1 and P2 included in the delivery confirmation information of the waste and the like (Fig. 4). (Refer) to the waste treatment management server SVG for registration.

The timing of transmitting the third information included in the delivery confirmation information and the photographs P1 and P2 may be arbitrary, and may be sequentially transmitted instead of being transmitted collectively.
Further, when the collection and transportation company terminal MD (see FIG. 2) is a computer installed at the location of the collection and transportation company, the third information and the photographs P1 and P2 may be transmitted using this computer. ..
In this way, the photographs P1 and P2 of the waste with location information taken by the collection and transportation company at the collection destination and the transportation destination are registered, so that the collection and transportation company does not actually carry the waste. Nevertheless, the fraudulent appearance of being transported is suppressed and the process of processing industrial waste is made transparent.

(Step S5)
The first to third condition determining means 208a to 208c respectively determine the success or failure of the first to third conditions based on the third information and the photographs P1 and P2 transmitted from the collection and transportation company terminal MD.
When the first to third condition determining means 208a to 208c determine that the first to third conditions are satisfied, the next step S6 is executed.

(Step S6)
The management company main-registers the manifest information included in the temporary registration information in the electronic manifest system. At that time, the management company transmits the manifest information to the electronic manifest system by the EDI method.
When the manifest information is main-registered, the fourth condition determining means 208d determines that the fourth condition is satisfied, and the next step S7 is executed.

(Step S7)
Each collection and transportation company reports to the electronic manifest system that the transportation of waste has been completed.
Specifically, the collection and transportation company directly accesses the JWNET server SVJ and registers the collection date and the disposal completion date of the waste by using the Web method. Since the commonly used Web method is used for registration, the collection and transportation company can report that the transportation of waste has been completed without hesitation about the operation method.
If a change is required, the fixed quantity of waste is also registered.

However, the waste collection date and the disposal completion date registered in step S7 can be registered in the previous step S6. That is, when the management company knows the waste collection date and the disposal completion date before step S6 is executed, the management company uses the EDI method to collect the waste collection date and the waste information together with the manifest information. The disposal completion date may be registered in the JWNET server SJ. When the collection date and the disposal completion date of the waste are registered in the previous step S6, the execution of this step S7 is omitted and the next step S8 is executed.

(Step S8)
The updating unit 206 (see FIG. 3) of the waste processing management server SVG updates the manifest information stored in the storage unit 202 based on the latest manifest information registered in the electronic manifest system. The update is executed every predetermined period.

(Step S9)
The discharger confirms the temporary registration information (manifest information and photographs P1 and P2) registered in the waste treatment management server SVG in step S4. If there is no problem in the temporary registration information, the discharger approves the collection and transportation company to execute the settlement process on the waste treatment management server SVG.
Upon approval, the fifth condition determining means 208e determines that the fifth condition is satisfied.

(Step S10)
The discharger refers to the manifest information (see FIG. 4) of the waste treatment management server SVG via the discharger terminal C1 or the discharger terminal C2 (see FIG. 2) to determine the waste treatment status. I can confirm.

Next, the settlement system 50 (see FIG. 2) used by the waste treatment management system 10 will be described.
The payment system 50 is a system that uses a block chain network BC (see FIG. 2) including a block chain group BC1, a block chain BC2, and a block chain BC3 shown in FIG. 6, and the initial bill recorded on the block chain. If the amount is revised, you can settle with the revised billing amount.
The blockchain is preferably a consortium type blockchain in which a plurality of specified businesses can participate.

The block chain group BC1 is composed of a plurality of block chains BC1a, BC1b, BC1c, BC1d, BC1e, BC1f, and records information to be managed in the above-mentioned waste treatment management.
In each block chain, a block is generated and information is recorded for each case specified by the manifest number. When the information is modified, the modified information is added to each block.

The block chain BC1a (an example of a calculation reference registration block chain) has a manifest number for identifying a case, a unit price of waste processing cost (information included in the processing fee information stored in the storage unit 202, Information on the calculation criteria that affects the amount of money) and information on the deadline for billing will be recorded as a block for each case.
In the block chain BC1b, the first information (see FIG. 4) of the delivery confirmation information including the manifest number is recorded as a block for each case.

In the block chain BC1c, the manifest number for identifying a case and the second information of the delivery confirmation information (see FIG. 4) are recorded as a block for each case.
In the block chain BC1d (an example of a calculation standard registration block chain), the manifest number for identifying a case and the third information of the delivery confirmation information (see FIG. 4) are recorded as a block for each case.
The manifest information (see FIG. 4) is recorded as a block for each case in the block chain BC1e.
The updated manifest information updated in step S8 is recorded as a block for each case in the block chain BC1f.

In the block chain BC2 (an example of a billing amount accumulating block chain), a manifest number for identifying each case and a charge amount of the case are recorded. When the billed amount is modified, the revised billed amount is recorded for each block.
For example, in FIG. 6, the following contents are recorded in each block of the block chain BC2.
1. Block with block height #00001 (1) Manifest number that identifies the case 001 (2) Charge amount 7,000 yen for the case 001 Note that the charge amount 7,000 yen recorded in this block is the last closing date Has already been billed (processed) when has passed.
2. 2. Block with height #00002 (1) Manifest number that identifies case 002 (2) Charge amount of case 002 10,000 yen 3. 3. Block with height #00003 (1) Manifest number that identifies case 003 (2) Charge amount of case 003 6,000 yen 4. Block with height #00004 (1) Manifest number that identifies case 001 (2) Charge amount of case 001 10,000 yen 5. 5. Block with height #00005 (1) Manifest number that identifies the case 004 (2) Billing amount 8,000 yen for the case 004 6. Block with block height #00006 (1) Manifest number for identifying case 005 (2) Charge amount 5,000 yen for case 005 7. Block with block height #00007 (1) Manifest number that identifies case 006 (2) Charge amount of case 006 JPY 9,000 8. Block with block height #00008 (1) Manifest number that identifies case 002 (2) Charge amount 12,000 yen after modification of case 002 9. Block of block height #000009 (1) Manifest number that identifies case 001 (2) Charge amount 5,000 yen after modification of case 001

In the block chain BC3 (an example of a block chain for registering the transferred amount), the transferred amount is recorded for each case. The transferred amount is the liquidation amount when the billed amount is corrected. Further, the height (information for specifying the block) of the final block (the block generated last) of the block chain BC2 is recorded for each case.
For example, in FIG. 6, the following contents are recorded in each block of the block chain BC3.
1. Block with block height #00001 (1) Manifest number that identifies case 001 (2) Transfer amount 7,000 yen that has been transferred after the last closing date of case 001 (3) Blockchain BC2 at the time of the previous transfer Final block height for matter 001 #00001
2. Block height #00002 (1) Manifest number that identifies case 002 (2) Transfer amount of case 002 12,000 yen (3) Final block height for case 002 of block chain BC2 at the time of transfer # 00008
3. Block height #00003 (1) Manifest number that identifies the case 003 (2) Transfer amount of the case 003 JPY 6,000 (3) Height of the final block for the case 003 of the blockchain BC2 at the time of transfer # 0000 3
4. Block height #00004 (1) Manifest number that identifies the case 001 (2) Clearing amount of the case 001-2,000 yen (3) Height of the final block for the case 001 of the block chain BC2 at the time of transfer # 0000 9

The payment system 50 includes the waste processing management server SVG and the nodes N1 and N2 described above, and uses the block chain group BC1 and the block chains BC2 and BC3 described above.

As shown in FIG. 7, the waste treatment management server SVG has an estimation/contract information management means 220, a business consignment management means 222, a business performance management means 224, and the above-mentioned contract creation means 210.

The estimate/contract information management means 220 can manage information relating to the calculation standard of the billed amount or the estimated amount in the waste treatment. The quotation/contract information management unit 220 stores the information in the storage unit 202 (see FIG. 4) after obtaining the approval from the discharger when the information is registered or changed by the collection and transportation company.
The business consignment management means 222 (see FIG. 7) can manage the delivery confirmation information. The business consignment management means 222, like the quotation/contract information management means 220, stores the information after receiving approval from the discharge business operator when the information is registered or changed by the collection and transportation company. (See 4).
The work record management means 224 (see FIG. 7) can manage record information such as the actual amount of waste discharged. Similar to the estimate/contract information management unit 220, the business performance management unit 224 stores the information after receiving the approval from the discharge business operator when the information is registered or changed by the collection and transportation company. (See 4).

The contract creating means 210 can create the first to third smart contracts with predetermined conditions and predetermined contents.
The first smart contract is that the predetermined condition is that any one of the information recorded in the block chains BC1a to BC1f is modified in the storage unit 202 of the waste treatment management server SVG, and the predetermined condition is determined in advance. What is done is to record the modified information in the corresponding block chains BC1a to BC1f of the block chain group BC1. Note that in FIG. 6, the predetermined conditions and contents are described only for the block chain BC1a, and are omitted for the block chains BC1b to BC1f.
In the second smart contract, the predetermined condition is that the information is added to any of the block chains BC1a to BC1f and the predetermined condition is satisfied, and the predetermined content corresponds to the block chain BC2. It is to record the billed amount of the case.
The third smart contract is that the predetermined condition is that the billing deadline has passed, and the predetermined content is the charge amount or the charge amount for each case based on the recorded contents of the block chain BC2 and the block chain BC3. It is to calculate the settlement amount, and record the amount of money transferred successfully and the height of the final block relating to the transferred matter recorded in the block chain BC2. The predetermined condition is not limited to the expiration of the billing closing date, and may be any condition.

The nodes N1 and N2 are, for example, nodes operated by a collection and transportation company, a financial institution, or the like. The number of nodes is not limited to two, and may be a node operated by a pre-authorized storage company or disposal company, if necessary.

Next, a payment method by the payment system 50 will be described. It should be noted that, if possible, the steps shown below may be executed in reverse order or in parallel. Further, this payment method is realized by a payment program executed by a distributed computing system including a plurality of nodes.

(Step P1)
A block chain group BC1, a block chain BC2 and a block chain BC3 are constructed.

(Step P2)
The contract creating means 210 (see FIG. 7) creates the above-mentioned first to third smart contracts.

(Step P3)
In order for the collection and transportation company to revise the calculation standards (for example, information on the unit price of waste treatment cost and the amount of waste discharged by item) that affect the amount charged to the discharger (an example of the requestee) When the revised calculation standard is registered in the waste treatment management server SVG, the quotation/contract information management means 220, the business consignment management means 222 or the business performance management means 224 that manages the corresponding information prompts the emission business operator for approval. ..
When the discharger approves the correction of the information, the corresponding estimate/contract information management means 220, business consignment management means 222 or business performance management means 224 stores the corrected information in the storage means 202 (see FIG. 4). ..

(Step P4)
In the previous step P3, when the modified information is stored in the storage unit 202, the condition of the first smart contract is satisfied, and the modified information is registered for each block in the corresponding block chains BC1a to BC1f.
For example, when the unit price of the disposal cost of the waste stored in the storage unit 202 (an information included in the processing charge information stored in the storage unit 202, which is an example of a calculation standard affecting the billing amount) is corrected. , The condition of the first smart contract is satisfied, and the modified unit price (an example of the modified calculation standard) is recorded for each block in the block chain BC1a.
In addition, for example, when the discharge amount of each item of waste stored in the storage unit 202 (an example of a calculation standard that affects the billed amount) is corrected, the condition of the first smart contract is satisfied, and the corrected discharge is performed. The quantity (an example of the modified calculation standard) is recorded for each block in the block chain BC1d.
That is, each time the first smart contract modifies the calculation standard for the amount charged to the claimant, the modified calculation standard is converted to the block chain BC1a or the block chain BC1d (an example of the calculation standard registration block chain). It will be recorded as the revised calculation standard.
Since the modified calculation standard is recorded in the block chain by the first smart contract, the recording means for recording the modified calculation standard in the block chain is realized by the first smart contract.

(Step P5)
In the previous step P4, when information is recorded in any of the block chains BC1a to BC1f and the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billing amount of the corresponding case is recalculated, and the block chain The corrected billing amount is recorded for each block in BC2.
For example, when the unit price of the modified processing cost is recorded in the block chain BC1a, the condition of the second smart contract is satisfied, and the billed amount of the relevant case is recalculated based on the modified unit price of the processing cost. The corrected billing amount is recorded for each block in the block chain BC2.
That is, the modified billing amount calculated based on the modified calculation standard by the second smart contract is recorded in the billing amount accumulating block chain BC2 (an example of the billing amount accumulating block chain).

(Step P6)
When the deadline for billing has passed, the conditions for the third smart contract are met, and the remittance amount is calculated based on the recalculated billing amount and the height of the final block of the cleared case that is recorded in the blockchain BC2. Then, the transfer means (not shown) executes a process of transferring the amount of money for clearing.
That is, the third smart contract calculates and clears the settlement amount for clearing the billed amount based on the revised billed amount.
After that, when it is confirmed that the transfer is successful, the amount transferred to the block chain BC3 and the height of the final block of the cleared applicable case recorded in the block chain BC2 are recorded.

As described above, according to the settlement method by the settlement system 50, at least all the modified calculation standards affecting the billed amount are recorded in the blockchain, and the billed amount is settled based on the modified calculation standard recorded in the blockchain. Therefore, even if the blockchain, which is difficult to tamper (correct), is used, if the initial billing amount is revised, the revised billing amount can be settled.

Next, regarding the settlement method after step P3, the collecting and transporting company collects and transports the waste of wood (processing unit price 100 yen/kg) for the case 001 shown in FIG. 6, and discharges 7,000 yen for 70 kg. A description will be given of a specific example in the case where the user has made a mistake and has corrected the discharge amount in the situation where the payment has already been made, but the input amount of 100 kg was erroneously input, so that the original correction amount of 50 kg was required.
In this specific example, the closing date is the end of the month.

Since the collection and transportation company noticed that the discharge amount of 70 kg was incorrect for the billing of the last month, if the discharge amount information (third information of the delivery confirmation information) is corrected from 70 kg to 100 kg, the business performance management means 224 prompts the emission business operator for approval.
When the discharger approves the correction of the information, the job performance management means 224 stores the corrected information in the storage means 202 (step P3).

Then, since the third information of the delivery confirmation condition is corrected in the waste treatment management server SVG, the condition of the first smart contract is satisfied, and the corrected information on the amount of discharged wood (100 kg) is obtained. The included third information is recorded as the block BLCa in the block chain BC1d (step P4).

The information (100 kg) of the modified wood emission amount is recorded in the block chain BC1d, and when the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billed amount for the case 001 is the modified third value. The re-calculated amount of 10,000 yen is recorded on the block chain BC2 as a block of height #00004 after being recalculated based on the information of (step P5).
In the blockchain BC2, the block (height #00001) related to the matter 001 is recorded as the billed amount (processed) of the last month, and the block (height #00001) related to the matter 002 is recorded as the billed amount (unprocessed) of this month. (00002) and the block (height #00003) related to the case 003 are already recorded.

After that, when he noticed that the discharge amount of 100 kg was an erroneous input, and the collector/collector corrects the information on the discharge amount of the waste wood (the third information of the delivery confirmation information) from 100 kg to 50 kg, the business performance management means 224 prompts the emission business operator for approval.
When the discharger approves the correction of the information, the job performance management means 224 stores the corrected information in the storage means 202 (step P3).

Then, since the third information of the delivery confirmation condition is corrected in the waste treatment management server SVG, the condition of the first smart contract is satisfied, and the information of the amount of discharged wood (50 kg) after the correction is obtained. The included third information is recorded as the block BLCd in the block chain BC1d (step P4).
It is to be noted that, until the step P4 is executed, in the block chain BC1d, the block BLCa, the block BLCb regarding the case 002, and the block BLCc regarding the case 005 are sequentially recorded.

The information (50 kg) of the modified wood emission amount is recorded in the block chain BC1d, and when the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billing amount for the case 001 is modified to the third condition. The billing amount of 5,000 yen after recalculation based on the information is corrected and recorded in the block chain BC2 as a block of height #00009 (step P5).
By the time the step P5 is executed, the block chain BC2 has a block (height #00005) related to the case 004, a block (height #00006) related to the case 005, and a block (height #00006) related to the case 006. (00007) and a block (height #00008) related to the case 002 are sequentially added.

When the billing deadline has passed, the conditions of the third smart contract are satisfied, and the recalculated billing amount of 5,000 yen and the deposited billing amount of 7,000 yen (see the block of block #BC01 height #00001) The difference of -2,000 yen is calculated as the liquidation amount, and -2,000 yen is transferred to the claimant. That is, 2,000 yen is returned to the demandee (step P6).

Here, the calculation of the settlement amount is 1) the billed amounts recorded in the block heights #00001, #00004, and #00009 related to the matter 001 of the block chain BC2, and 2) the matter processed last month of the block chain BC3, respectively. It is performed based on the height #00001 of the final block (information indicating the processed block recorded in the block chain BC2) recorded in the block of height #00001 related to 001.

If the transfer is successful, the settlement amount of −2,000 yen transferred to the block chain BC3 is recorded. Further, the height #000009 of the last block of the case 001 recorded in the block chain BC2 is recorded and used in the next calculation of the settlement amount. That is, in the block height #00009 of the block chain BC3, the settlement amount of −2,000 yen and the block height #00009 are recorded.
As described above, in this specific example, since the original charge of 5,000 yen was billed at 7,000 yen, a process of returning the difference of 2,000 is performed.

As described above, according to the settlement method by the settlement system 50, it is possible to provide the transparency of the billing cost and the convenience that it can be corrected later.

Explaining from another perspective, the settlement system 50 records the modified calculation standard as the modified calculation standard in the calculation standard registration blockchain every time the calculation standard of the amount charged to the discharger is modified. And a clearing means for calculating and clearing a clearing amount for clearing the billed amount based on the revised calculation standard. Of the recording means and the settlement means, at least the recording means is realized by a smart contract created by the contract creating means included in the waste processing management server.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and changes in conditions and the like without departing from the gist are all within the scope of application of the present invention.
The settlement system (settlement method) is not applied to settlement of billing costs for waste disposal, but can be applied to settlement of billing costs for any treatment.

The payment system according to the embodiment of the present invention is applied to, for example, the payment of billing costs related to the treatment of wastes managed by the waste treatment management system 10.
First, the management of waste treatment by the waste treatment management system 10 will be described.
The waste treatment process includes, for example, as shown in FIG. 1, a discharge process P1, a collection and transportation process P2, a storage process P3, and a disposal process P4.
The discharge step P1 is a step in which, for example, a remodeling business operator (one example of a recycle business operator) who has received an order from a customer for a building remodeling business discharges the waste generated by the remodeling work. Here, this renovation business operator develops a business in a franchise format, and has a headquarters as a discharge business operator and a member store. However, the emission business may not be a franchise-type business and may be a single business. Therefore, hereinafter, the renovation company may be simply referred to as an “emission company” without distinguishing between the headquarters and the member stores.

The collecting and transporting step P2 is a step in which a collecting and transporting company collects and transports waste and transports it to a predetermined storage location.

The storage process P3 is a process in which the storage company stores the waste in the storage facility. Note that the storage company may be included in the above-mentioned collection/transportation company in the storage process P3, since a work of collecting and transporting waste may occur as necessary in this storage process P3.

The disposal process P4 is a process in which the disposal company disposes the waste. Note that the disposal company may be included in the above-mentioned collection/transportation company in the disposal process P4, since a work of collecting and transporting waste may occur as necessary in this disposal process P4.

As shown in FIG. 2, the waste treatment management system 10 includes waste discharger terminals C1 and C2, a collection transporter terminal MD, and a waste treatment management server SVG, and manages waste treatment based on an electronic manifest. it can. The discharge company terminals C1 and C2, the collection and transportation company terminal MD, and the waste treatment management server SVG are connected to each other via the Internet (an example of a network) N.
Here, the Internet N is connected to an electronic manifest system (JWNET server SVJ) operated by the Japan Industrial Waste Treatment Promotion Center (hereinafter referred to as “information processing center”). That is, the information processing center (JWNET server SVJ) can be accessed from each of the discharge company terminals C1 and C2, the collection and transportation company terminal MD, and the waste processing management server SVG.

The discharge company terminals C1 and C2 are terminals operated by the above-mentioned reform company. The discharging company terminal C1 and the discharging company terminal C2 are, for example, computers installed at the locations of the headquarters and member stores, respectively.
In the waste treatment management system 10, the member store may perform the operation or work performed by the head office instead, or the head office may perform the operation or work performed by the member store instead.

The collection and transportation company terminal MD is a terminal operated by the collection and transportation company, and is, for example, a mobile terminal carried by a person in charge of the collection and transportation company. This mobile terminal has a camera and a GPS function.
The collection and transportation company terminal MD may be any computer as long as it can be connected to the Internet N, and may be a computer installed at the location of the collection and transportation company. Further, a plurality of collection/transportation carrier terminals MD may exist for one collection/transportation carrier.

The waste treatment management server SVG is a server operated by a management company that manages the treatment of waste.
As shown in FIG. 3, the waste treatment management server SVG includes a storage unit 202, a trader selection unit 203, a delivery confirmation information transmission unit 204, a position information confirmation unit 205, an update unit 206, and first to fifth condition determination units. It has 208a to 208e and a contract creating means 210.
Each of these means is realized by the waste treatment management server SVG by a program executed by the waste treatment management server SVG.

The storage unit 202 has, for example, a hard disk drive device, and as shown in FIG. 4, can store delivery confirmation information, temporary registration information, a database of collection and transportation companies, processing fee information, and transportation destination location information.
The delivery confirmation information includes at least information described on the delivery confirmation slip in the electronic manifest system, and includes first information, second information, and third information.

The first information is information provided by the waste discharger accessing the waste treatment management server SVG. For example, the manifest number, the customer name (reform requester name), the zip code of the customer's house, and the waste. Address of the customer's house (collection location of waste), delivery construction slip number, planned discharge date, work process date, remodeling type, registration cooperation company (substantially based on the request of the remodeling company) It includes information on the renovation company that performs building renovation work, collection conditions, and waste emission forecasts. The collection condition is information such as the type of collection vehicle, the presence/absence of special collection that needs to be carried out or carried by two people, and the planned discharge amount of waste.
The second information is information provided by the trader selection means 203 or the management company, which will be described later, and is, for example, the name and location of the collection and transportation company.
The third information is information provided by the collection and transportation company accessing the waste treatment management server SVG. For example, the date of delivery, the discharge amount of each waste item, the packing form, and the waste amount. Information such as the location of the transportation destination (disposal site, etc.), waste disposal method, vehicle number, vehicle name, etc.

The temporary registration information is at least information including manifest information and information of a plurality of photographs with position information including position information of the shooting location where the waste was shot.
The manifest information is information registered in the electronic manifest system, and is configured based on the delivery confirmation information.
The plurality of photographs with position information are a photograph P1 of waste taken by the collection and transportation company at the collection destination and a photograph P2 of waste taken at the transportation destination, respectively. The position information of the shooting location acquired using GPS is associated with each of the photographs P1 and P2.

The collection and transportation company database is a database in which a plurality of collection and transportation companies are registered. Information (names, locations, etc.) of a plurality of collection and transportation companies is registered in this database. In addition, each collection and transportation company registered in this database is a highly reliable company that has been examined by the management company to meet predetermined criteria.

The processing fee information is information on the fee for processing the waste set by each of the plurality of collection and transportation companies. The treatment fee is set by each collection and transportation company accessing the waste treatment management server SVG.
The processing fee consists of collection and transportation costs, disposal costs, industrial waste tax, and additional fees (costs such as the distance to the waste collection destination and the burden of loading work).

The transportation destination location information is information on the location of the transportation destination where the collection and transportation company transports the waste, and is preset by the management company. The location of the transportation destination is, for example, the location of the disposal site.

The trader selection means 203 processes the waste based on the location of the collection destination of the waste (address of the customer's house), the location of the collection transporter, and the processing fee information of each collection transporter stored in the storage means 202. You can calculate the charge and select the collection and transportation company with the lowest processing charge.

The delivery confirmation information transmitting means 204 can transmit the delivery confirmation information to the collection and transportation company terminal MD via the Internet N.

The position information confirmation unit 205 detects that the position included in the information of the photo P1 is within a preset distance range from the information of the location of the collection destination, and the position included in the information of the photo P2 is from the information of the location of the transportation destination. It can be confirmed that the distance is within the preset distance. The range of this distance is stored in the storage unit 202.

The update unit 206 can update the manifest information stored in the storage unit 202 based on the latest manifest information registered in the electronic manifest system. The updating unit 206 can update the manifest information for each predetermined period.

The first condition judging means 208a can judge whether the first condition is satisfied. The first condition is that the position included in the information of the photo P1 is within a preset distance from the information of the location of the collection destination included in the delivery confirmation information, and the position included in the information of the photo P2 is That is, it is within the range of a preset distance from the delivery confirmation information or the location information of the delivery destination included in the delivery destination location information.
Therefore, when the above-mentioned position information confirmation means 205 confirms that the position information associated with the photographs P1 and P2 of the waste is within the range of the preset distance from the locations of the collection destination and the transportation destination, respectively. The first condition determination unit 208a determines that the first condition is satisfied.

The second condition determining means 208b can determine whether the second condition is satisfied. The second condition is that the amount of waste obtained from each of the photographs P1 and P2 and the amount of waste input by the collection and transportation company via the terminal of the collection and transportation company match. It should be noted that the term “match” here does not mean a match in a strict sense. That is, “match” means “substantial match” in which a predetermined degree of mismatch is allowed (hereinafter the same).
The amount of waste is obtained from each of the photographs P1 and P2 by using, for example, AR (Augmented Reality).

The third condition determining unit 208c can determine whether the third condition is satisfied. The third condition is that the waste recorded in the photo P1 and the waste recorded in the photo P2 are the same as the type of waste input by the collection and transportation company via the terminal of the collection and transportation company. is there. It should be noted that the term “identical” here does not mean the same in a strict sense. That is, “identical” means “substantially identical” in which a predetermined degree of disparity is allowed (hereinafter, the same).
The types of the waste recorded in the photograph P1 and the waste recorded in the photograph P2 are obtained by image processing using, for example, AI (Artificial Intelligence).

The fourth condition determining means 208d can determine whether or not the fourth condition is satisfied. The fourth condition is that the manifest information configured based on the delivery confirmation information is main-registered in the electronic manifest system.
The fourth condition determining unit 208d monitors that the manifest information is main-registered in the electronic manifest system, and determines that the fourth condition is satisfied when the main registration is performed.

The fifth condition determining means 208e can determine whether the fifth condition is satisfied. The fifth condition is that the discharge business operator or the management business operator approves the collection and transportation company to execute the settlement process.
The fifth condition determining unit 208e monitors that the discharging business operator or the management business company approves the execution of the settlement process, and when the approval is made, determines that the fifth condition is satisfied.

The contract creating means 210 can create a smart contract for the block chains BC1a, BC1b, BC1c, BC1d, BC1e, BC2, and BC3 that have been built in advance.
The contract creating means 210 will be described later.

Next, a waste treatment management method using the waste treatment management system 10 (excluding settlement processing for a collection and transportation company) will be described with reference to FIG. It should be noted that, if possible, the steps shown below may be executed in reverse order or in parallel.

(Step S1)
The discharging company (headquarters or member store) acquires the manifest number in the electronic manifest. The manifest number can be obtained by utilizing the reservation registration provided by the information processing center.
On the other hand, the contract creating unit 210 creates a contract (smart contract) having predetermined conditions and predetermined contents for waste processing corresponding to the acquired manifest number. The specific contents of the smart contract will be described later.
The contract does not have to be created in step S1 and may be created in step S2, step S3, or step S4. The created contract will be registered in the blockchain at an appropriate timing.

(Step S2)
The discharger receives an order from a customer for renovation work. When the details of the reform work are clarified and it is determined that the waste generated by this reform work needs to be treated, the discharge business operator (member store) uses the discharge business operator terminal C2 (see FIG. 2). Then, the first information (see FIG. 4) other than the manifest number included in the delivery confirmation information is registered in the waste processing management server SVG.
The waste management is started by the registration of the first information included in the delivery confirmation information.

(Step S3)

The company selection means 203 (see FIG. 3) of the waste treatment management server SVG selects a collection and transportation company.
In this step S3, the management company manually confirms the delivery confirmation information (see FIG. 4), and based on the delivery confirmation information, it is appropriate for the collection and transportation of the waste from a plurality of collection and transportation companies. You may choose a different collection and transportation company.
Thereafter, the selected collection hauler is arranged.
In addition, since the second information included in the delivery confirmation information is confirmed by this step, the management company registers the second information in the waste treatment management server SVG (see FIG. 2).

(Step S4)
The selected collection and transportation company acquires and confirms the delivery confirmation information stored in the storage means 202 (see FIG. 3) of the waste treatment management server SVG. In detail, the delivery confirmation information transmitting means 204 (see FIG. 3) of the waste treatment management server SVG transmits the delivery confirmation information (see FIG. 4) based on the request from the collection and transportation company.
Next, the collection and transportation company transmits the acquired delivery confirmation information to a remodeling company (a company that substantially carries out the remodeling work of the building based on the request of the remodeling business operator) by using, for example, FAX. The reformer who received the FAX confirms the delivery confirmation information and, for example, when there is a change in the scheduled discharge date, notifies the collection and transportation company of the change.

Next, when the renovation work is performed by the renovation company and the waste is discharged, the collection and transportation company goes to the waste discharge site on the scheduled discharge date included in the delivery confirmation information and collects the waste.
At the waste collection site (collection destination), the collection and transportation company photographs the discharged waste P1 using the collection and transportation company terminal MD (see FIG. 2). This photograph P1 includes the position information acquired at the time of photographing by GPS. After transporting the collected waste, the collection and transportation company uses the collection and transportation company terminal MD to take a picture P2 of the waste at the disposal site of the transportation destination. This photograph P2 also includes the position information acquired at the time of photographing by GPS.
After that, the collection and transportation company uses the collection and transportation company terminal MD to discharge the discharge amount of each waste item and the third information and photographs P1 and P2 included in the delivery confirmation information of the waste and the like (Fig. 4). (Refer) to the waste treatment management server SVG for registration.

The timing of transmitting the third information included in the delivery confirmation information and the photographs P1 and P2 may be arbitrary, and may be sequentially transmitted instead of being transmitted collectively.
Further, when the collection and transportation company terminal MD (see FIG. 2) is a computer installed at the location of the collection and transportation company, the third information and the photographs P1 and P2 may be transmitted using this computer. ..
In this way, the photographs P1 and P2 of the waste with location information taken by the collection and transportation company at the collection destination and the transportation destination are registered, so that the collection and transportation company does not actually carry the waste. Nevertheless, the fraudulent appearance of being transported is suppressed and the process of processing industrial waste is made transparent.

(Step S5)
The first to third condition determining means 208a to 208c respectively determine the success or failure of the first to third conditions based on the third information and the photographs P1 and P2 transmitted from the collection and transportation company terminal MD.
When the first to third condition determining means 208a to 208c determine that the first to third conditions are satisfied, the next step S6 is executed.

(Step S6)
The management company main-registers the manifest information included in the temporary registration information in the electronic manifest system. At that time, the management company transmits the manifest information to the electronic manifest system by the EDI method.
When the manifest information is main-registered, the fourth condition determining means 208d determines that the fourth condition is satisfied, and the next step S7 is executed.

(Step S7)
Each collection and transportation company reports to the electronic manifest system that the transportation of waste has been completed.
Specifically, the collection and transportation company directly accesses the JWNET server SVJ and registers the collection date and the disposal completion date of the waste by using the Web method. Since the commonly used Web method is used for registration, the collection and transportation company can report that the transportation of waste has been completed without hesitation about the operation method.
If a change is required, the fixed quantity of waste is also registered.

However, the waste collection date and the disposal completion date registered in step S7 can be registered in the previous step S6. That is, when the management company knows the waste collection date and the disposal completion date before step S6 is executed, the management company uses the EDI method to collect the waste collection date and the waste information together with the manifest information. The disposal completion date may be registered in the JWNET server SJ. When the collection date and the disposal completion date of the waste are registered in the previous step S6, the execution of this step S7 is omitted and the next step S8 is executed.

(Step S8)
The updating unit 206 (see FIG. 3) of the waste processing management server SVG updates the manifest information stored in the storage unit 202 based on the latest manifest information registered in the electronic manifest system. The update is executed every predetermined period.

(Step S9)
The discharger confirms the temporary registration information (manifest information and photographs P1 and P2) registered in the waste treatment management server SVG in step S4. If there is no problem in the temporary registration information, the discharger approves the collection and transportation company to execute the settlement process on the waste treatment management server SVG.
Upon approval, the fifth condition determining means 208e determines that the fifth condition is satisfied.

(Step S10)
The discharger refers to the manifest information (see FIG. 4) of the waste treatment management server SVG via the discharger terminal C1 or the discharger terminal C2 (see FIG. 2) to determine the waste treatment status. I can confirm.

Next, the settlement system 50 (see FIG. 2) used by the waste treatment management system 10 will be described.
The payment system 50 is a system that uses a block chain network BC (see FIG. 2) including a block chain group BC1, a block chain BC2, and a block chain BC3 shown in FIG. 6, and the initial bill recorded on the block chain. If the amount is revised, you can settle with the revised billing amount.
The blockchain is preferably a consortium type blockchain in which a plurality of specified businesses can participate.

The block chain group BC1 is composed of a plurality of block chains BC1a, BC1b, BC1c, BC1d, BC1e, BC1f, and records information to be managed in the above-mentioned waste treatment management.
In each block chain, a block is generated and information is recorded for each case specified by the manifest number. When the information is modified, the modified information is added to each block.

The block chain BC1a (an example of a calculation reference registration block chain) has a manifest number for identifying a case, a unit price of waste processing cost (information included in the processing fee information stored in the storage unit 202, Information on the calculation criteria that affects the amount of money) and information on the deadline for billing will be recorded as a block for each case.
In the block chain BC1b, the first information (see FIG. 4) of the delivery confirmation information including the manifest number is recorded as a block for each case.

In the block chain BC1c, the manifest number for identifying a case and the second information of the delivery confirmation information (see FIG. 4) are recorded as a block for each case.
In the block chain BC1d (an example of a calculation standard registration block chain), the manifest number for identifying a case and the third information of the delivery confirmation information (see FIG. 4) are recorded as a block for each case.
The manifest information (see FIG. 4) is recorded as a block for each case in the block chain BC1e.
The updated manifest information updated in step S8 is recorded as a block for each case in the block chain BC1f.

In the block chain BC2 (an example of a billing amount accumulating block chain), a manifest number for identifying each case and a charge amount of the case are recorded. When the billed amount is modified, the revised billed amount is recorded for each block.
For example, in FIG. 6, the following contents are recorded in each block of the block chain BC2.
1. Block with block height #00001 (1) Manifest number that identifies the case 001 (2) Charge amount 7,000 yen for the case 001 Note that the charge amount 7,000 yen recorded in this block is the last closing date Has already been billed (processed) when has passed.
2. 2. Block with height #00002 (1) Manifest number that identifies case 002 (2) Charge amount of case 002 10,000 yen 3. 3. Block with height #00003 (1) Manifest number that identifies case 003 (2) Charge amount of case 003 6,000 yen 4. Block with height #00004 (1) Manifest number that identifies case 001 (2) Charge amount of case 001 10,000 yen 5. 5. Block with height #00005 (1) Manifest number that identifies the case 004 (2) Billing amount 8,000 yen for the case 004 6. Block with block height #00006 (1) Manifest number for identifying case 005 (2) Charge amount 5,000 yen for case 005 7. Block with block height #00007 (1) Manifest number that identifies case 006 (2) Charge amount of case 006 JPY 9,000 8. Block with block height #00008 (1) Manifest number that identifies case 002 (2) Charge amount 12,000 yen after modification of case 002 9. Block of block height #000009 (1) Manifest number that identifies case 001 (2) Charge amount 5,000 yen after modification of case 001

In the block chain BC3 (an example of a block chain for registering the transferred amount), the transferred amount is recorded for each case. The transferred amount is the liquidation amount when the billed amount is corrected. Further, the height (information for specifying the block) of the final block (the block generated last) of the block chain BC2 is recorded for each case.
For example, in FIG. 6, the following contents are recorded in each block of the block chain BC3.
1. Block with block height #00001 (1) Manifest number that identifies case 001 (2) Transfer amount 7,000 yen that has been transferred after the last closing date of case 001 (3) Blockchain BC2 at the time of the previous transfer Final block height for matter 001 #00001
2. Block height #00002 (1) Manifest number that identifies case 002 (2) Transfer amount of case 002 12,000 yen (3) Final block height for case 002 of block chain BC2 at the time of transfer # 00008
3. Block height #00003 (1) Manifest number that identifies the case 003 (2) Transfer amount of the case 003 JPY 6,000 (3) Height of the final block for the case 003 of the blockchain BC2 at the time of transfer # 0000 3
4. Block height #00004 (1) Manifest number that identifies the case 001 (2) Clearing amount of the case 001-2,000 yen (3) Height of the final block for the case 001 of the block chain BC2 at the time of transfer # 0000 9

The payment system 50 includes the waste processing management server SVG and the nodes N1 and N2 described above, and uses the block chain group BC1 and the block chains BC2 and BC3 described above.

As shown in FIG. 7, the waste treatment management server SVG has an estimation/contract information management means 220, a business consignment management means 222, a business performance management means 224, and the above-mentioned contract creation means 210.

The estimate/contract information management means 220 can manage information relating to the calculation standard of the billed amount or the estimated amount in the waste treatment. The quotation/contract information management unit 220 stores the information in the storage unit 202 (see FIG. 4) after obtaining the approval from the discharger when the information is registered or changed by the collection and transportation company.
The business consignment management means 222 (see FIG. 7) can manage the delivery confirmation information. The business consignment management means 222, like the quotation/contract information management means 220, stores the information after receiving approval from the discharge business operator when the information is registered or changed by the collection and transportation company. (See 4).
The work record management means 224 (see FIG. 7) can manage record information such as the actual amount of waste discharged. Similar to the estimate/contract information management unit 220, the business performance management unit 224 stores the information after receiving the approval from the discharge business operator when the information is registered or changed by the collection and transportation company. (See 4).

The contract creating means 210 can create the first to third smart contracts with predetermined conditions and predetermined contents.
The first smart contract is that the predetermined condition is that any one of the information recorded in the block chains BC1a to BC1f is modified in the storage unit 202 of the waste treatment management server SVG, and the predetermined condition is determined in advance. What is done is to record the modified information in the corresponding block chains BC1a to BC1f of the block chain group BC1. Note that in FIG. 6, the predetermined conditions and contents are described only for the block chain BC1a, and are omitted for the block chains BC1b to BC1f.
In the second smart contract, the predetermined condition is that the information is added to any of the block chains BC1a to BC1f and the predetermined condition is satisfied, and the predetermined content corresponds to the block chain BC2. It is to record the billed amount of the case.
The third smart contract is that the predetermined condition is that the billing deadline has passed, and the predetermined content is the charge amount or the charge amount for each case based on the recorded contents of the block chain BC2 and the block chain BC3. It is to calculate the settlement amount, and record the amount of money transferred successfully and the height of the final block relating to the transferred matter recorded in the block chain BC2. The predetermined condition is not limited to the expiration of the billing closing date, and may be any condition.

The nodes N1 and N2 are, for example, nodes operated by a collection and transportation company, a financial institution, or the like. The number of nodes is not limited to two, and may be a node operated by a pre-authorized storage company or disposal company, if necessary.

Next, a payment method by the payment system 50 will be described. It should be noted that, if possible, the steps shown below may be executed in reverse order or in parallel. Further, this payment method is realized by a payment program executed by a distributed computing system including a plurality of nodes.

(Step P1)
A block chain group BC1, a block chain BC2 and a block chain BC3 are constructed.

(Step P2)
The contract creating means 210 (see FIG. 7) creates the above-mentioned first to third smart contracts.

(Step P3)
In order for the collection and transportation company to revise the calculation standards (for example, information on the unit price of waste treatment cost and the amount of waste discharged by item) that affect the amount charged to the discharger (an example of the requestee) When the revised calculation standard is registered in the waste treatment management server SVG, the quotation/contract information management means 220, the business consignment management means 222 or the business performance management means 224 that manages the corresponding information prompts the emission business operator for approval. ..
When the discharger approves the correction of the information, the corresponding estimate/contract information management means 220, business consignment management means 222 or business performance management means 224 stores the corrected information in the storage means 202 (see FIG. 4). ..

(Step P4)
In the previous step P3, when the modified information is stored in the storage unit 202, the condition of the first smart contract is satisfied, and the modified information is registered for each block in the corresponding block chains BC1a to BC1f.
For example, when the unit price of the disposal cost of the waste stored in the storage unit 202 (an information included in the processing charge information stored in the storage unit 202, which is an example of a calculation standard affecting the billing amount) is corrected. , The condition of the first smart contract is satisfied, and the modified unit price (an example of the modified calculation standard) is recorded for each block in the block chain BC1a.
In addition, for example, when the discharge amount of each item of waste stored in the storage unit 202 (an example of a calculation standard that affects the billed amount) is corrected, the condition of the first smart contract is satisfied, and the corrected discharge is performed. The quantity (an example of the modified calculation standard) is recorded for each block in the block chain BC1d.
That is, each time the first smart contract modifies the calculation standard for the amount charged to the claimant, the modified calculation standard is converted to the block chain BC1a or the block chain BC1d (an example of the calculation standard registration block chain). It will be recorded as the revised calculation standard.
Since the modified calculation standard is recorded in the block chain by the first smart contract, the recording means for recording the modified calculation standard in the block chain is realized by the first smart contract.

(Step P5)
In the previous step P4, when information is recorded in any of the block chains BC1a to BC1f and the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billing amount of the corresponding case is recalculated, and the block chain The corrected billing amount is recorded for each block in BC2.
For example, when the unit price of the modified processing cost is recorded in the block chain BC1a, the condition of the second smart contract is satisfied, and the billed amount of the relevant case is recalculated based on the modified unit price of the processing cost. The corrected billing amount is recorded for each block in the block chain BC2.
That is, the modified billing amount calculated based on the modified calculation standard by the second smart contract is recorded in the billing amount accumulating block chain BC2 (an example of the billing amount accumulating block chain).

(Step P6)
When the deadline for billing has passed, the conditions for the third smart contract are met, and the remittance amount is calculated based on the recalculated billing amount and the height of the final block of the cleared case that is recorded in the blockchain BC2. Then, the transfer means (not shown) executes a process of transferring the amount of money for clearing.
That is, the third smart contract calculates and clears the settlement amount for clearing the billed amount based on the revised billed amount.
After that, when it is confirmed that the transfer is successful, the amount transferred to the block chain BC3 and the height of the final block of the cleared applicable case recorded in the block chain BC2 are recorded.

As described above, according to the settlement method by the settlement system 50, at least all the modified calculation standards affecting the billed amount are recorded in the blockchain, and the billed amount is settled based on the modified calculation standard recorded in the blockchain. Therefore, even if the blockchain, which is difficult to tamper (correct), is used, if the initial billing amount is revised, the revised billing amount can be settled.

Next, regarding the settlement method after step P3, the collecting and transporting company collects and transports the waste of wood (processing unit price 100 yen/kg) for the case 001 shown in FIG. 6, and discharges 7,000 yen for 70 kg. A description will be given of a specific example in the case where the user has made a mistake and has corrected the discharge amount in the situation where the payment has already been made, but the input amount of 100 kg was erroneously input, so that the original correction amount of 50 kg was required.
In this specific example, the closing date is the end of the month.

Since the collection and transportation company noticed that the discharge amount of 70 kg was incorrect for the billing of the last month, if the discharge amount information (third information of the delivery confirmation information) is corrected from 70 kg to 100 kg, the business performance management means 224 prompts the emission business operator for approval.
When the discharger approves the correction of the information, the job performance management means 224 stores the corrected information in the storage means 202 (step P3).

Then, since the third information of the delivery confirmation condition is corrected in the waste treatment management server SVG, the condition of the first smart contract is satisfied, and the corrected information on the amount of discharged wood (100 kg) is obtained. The included third information is recorded as the block BLCa in the block chain BC1d (step P4).

The information (100 kg) of the modified wood emission amount is recorded in the block chain BC1d, and when the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billed amount for the case 001 is the modified third value. The re-calculated amount of 10,000 yen is recorded on the block chain BC2 as a block of height #00004 after being recalculated based on the information of (step P5).
In the blockchain BC2, the block (height #00001) related to the matter 001 is recorded as the billed amount (processed) of the last month, and the block (height #00001) related to the matter 002 is recorded as the billed amount (unprocessed) of this month. (00002) and the block (height #00003) related to the case 003 are already recorded.

After that, when he noticed that the discharge amount of 100 kg was an erroneous input, and the collector/collector corrects the information on the discharge amount of the waste wood (the third information of the delivery confirmation information) from 100 kg to 50 kg, the business performance management means 224 prompts the emission business operator for approval.
When the discharger approves the correction of the information, the job performance management means 224 stores the corrected information in the storage means 202 (step P3).

Then, since the third information of the delivery confirmation condition is corrected in the waste treatment management server SVG, the condition of the first smart contract is satisfied, and the information of the amount of discharged wood (50 kg) after the correction is obtained. The included third information is recorded as the block BLCd in the block chain BC1d (step P4).
It is to be noted that, until the step P4 is executed, in the block chain BC1d, the block BLCa, the block BLCb regarding the case 002, and the block BLCc regarding the case 005 are sequentially recorded.

The information (50 kg) of the modified wood emission amount is recorded in the block chain BC1d, and when the predetermined condition is satisfied, the condition of the second smart contract is satisfied, and the billing amount for the case 001 is modified to the third condition. The billing amount of 5,000 yen after recalculation based on the information is corrected and recorded in the block chain BC2 as a block of height #00009 (step P5).
By the time the step P5 is executed, the block chain BC2 has a block (height #00005) related to the case 004, a block (height #00006) related to the case 005, and a block (height #00006) related to the case 006. (00007) and a block (height #00008) related to the case 002 are sequentially added.

When the billing deadline has passed, the conditions of the third smart contract are satisfied, and the recalculated billing amount of 5,000 yen and the deposited billing amount of 7,000 yen (see the block of block #BC01 height #00001) The difference of -2,000 yen is calculated as the liquidation amount, and -2,000 yen is transferred to the claimant. That is, 2,000 yen is returned to the demandee (step P6).

Here, the calculation of the settlement amount is 1) the billed amounts recorded in the block heights #00001, #00004, and #00009 related to the matter 001 of the block chain BC2, and 2) the matter processed last month of the block chain BC3, respectively. It is performed based on the height #00001 of the final block (information indicating the processed block recorded in the block chain BC2) recorded in the block of height #00001 related to 001.

If the transfer is successful, the settlement amount of −2,000 yen transferred to the block chain BC3 is recorded. Further, the height #000009 of the last block of the case 001 recorded in the block chain BC2 is recorded and used in the next calculation of the settlement amount. That is, in the block height #00009 of the block chain BC3, the settlement amount of −2,000 yen and the block height #00009 are recorded.
As described above, in this specific example, since the original charge of 5,000 yen was billed at 7,000 yen, a process of returning the difference of 2,000 is performed.

As described above, according to the settlement method by the settlement system 50, it is possible to provide the transparency of the billing cost and the convenience that it can be corrected later.

Explaining from another perspective, the settlement system 50 records the modified calculation standard as the modified calculation standard in the calculation standard registration blockchain every time the calculation standard of the amount charged to the discharger is modified. And a clearing means for calculating and clearing a clearing amount for clearing the billed amount based on the revised calculation standard. Of the recording means and the settlement means, at least the recording means is realized by a smart contract created by the contract creating means included in the waste processing management server.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and changes in conditions and the like without departing from the gist are all within the scope of application of the present invention.
The settlement system (settlement method) is not applied to settlement of billing costs for waste disposal, but can be applied to settlement of billing costs for any treatment.
