The service providing API can be easily introduced by using the private lodging API.

(Recording device 6)
As shown in FIG. 3, the recording device 6 includes a block chain 61 that records ledger information. Note that the recording device 6 may be constituted by a server or may be constituted by an IPFS (InterPlanetary File System) which is a distributed file system. The ledger information is exemplified by order information, payment information, secret key information, device information, and token management information.

  The order contract information includes a store wallet address, a customer wallet address, a support organization wallet address, the number of deposit tokens, a reservation, a price, and a service charge. Note that the order contract information may include information on “reservation” and “order”. The settlement information is exemplified by the order number, the actual number of stays, and the number of consumed tokens. Examples of the secret key information include an order number, a device ID, a secret key type, secret key data, an application start time, and an application end time. The device information includes a device ID, a device MAC address, and a store wallet address.

(Recording device 6: block chain 61)
The blockchain 61 distributes data to a plurality of distributed computers, applies encryption technology and P2P (peer-to-peer) network technology, and manages and operates a specific organization or company. This is a technology that prevents data tampering, has high fault tolerance, and enables automatic transactions by configuring a "centralized" distributed network. In other words, the block chain 61 makes it difficult to falsify the ledger information by sequentially connecting ledger information, which is transaction data, in the form of an information block using a hash value in the form of a chain.

  More specifically, the block chain 61 includes transaction data, a hash value of a previous information block, a nonce value, and the like in each information block. Here, the “transaction data” is data indicating some transaction information such as a remittance amount or a sender. The “hash value of the previous block” and the “nonce value” are data for writing transaction data to the network of the block chain. The nonce value is a value when a hash value calculated from transaction information to be recorded in an information block by a hash function satisfies a predetermined condition.

  The blockchain 61 employs a consensus algorithm that generates information blocks such as POW [Proof Of Work], POS [Proof Of Stake], DPoS (Delegated Proof of Stake).

  Consensus algorithms, such as POW and POS, record the ledger information associated with a new procedure by mining each distributed computer, and record the results that most computers agree to have the correct contents in each form. Thereby, the contents of the agreed ledger information stored in each computer are made the same. Then, when a nonce to be written to the information block is obtained by mining, the process of writing a new information block to the network is repeated, so that ledger information is sequentially recorded in the form of an information block. I have.

  Here, "mining" is a process of finding a nonce. In POW, a mining incentive is secured by rewarding a person (minor) who first finds a nonce. On the other hand, POS issues interest as a reward according to the number of virtual currency possessions, so that mining is automatically performed with interest.

  DPoS selects (delegates) by voting those who will further approve transactions from among those who hold cryptocurrencies, and the elected people will approve transactions on behalf of the holders, and the results will be obtained there Rewards are distributed to those who vote. According to the DPoS having such a configuration, by limiting approvers in advance, it is possible to reduce the number of approvals required for transaction approval and increase transaction speed.

  In the block chain 61, information blocks may be sequentially generated by an architecture based on an acyclic directed graph structure. For example, the blockchain 61 may employ another distributed ledger architecture such as a DAG (Directed acyclic graph).

(Recording device 6: block chain 61: main chain 611, sub-chain 612)
The block chain 61 has a main chain 611 and a sub-chain 612 that sequentially generate information blocks including ledger information. The sub-chain 612 generates an information block at a generation speed higher than the generation speed of the information block in the main chain 611. The reason for this is that the sub-chain 612 does not depend on the block generation of the main chain 611 by being anchored to the main chain 611.

  The side chain 612 is made accessible to the payment system 11 and the smart device 4, and records and reads out general payment information in the payment system 11 and the smart device 4. On the other hand, the main chain 611 can record and read out basic information such as assets. A two-ways peg method in which data is linked between the main chain 611 and the sub-chain 612 may be adopted. Further, ERC20 may be adopted instead of the two-ways peg method.

  The two-ways peg method has the following functions. Specifically, a function of transferring the original currency of the main chain 611 (for example, bitcoin) from the main chain 611 to the sub-chain 612, and a function of transferring only the original currency of the main chain 111 from the sub-chain 612 to the main chain 611. When the currency flow is from the main chain 611 to the sub-chain 612, the function of disabling the original currency of the main chain 611 by the transferred currency and the currency flow from the sub-chain 612 to the main chain 611 In the case of, the function of unlocking the original currency of the main chain 611 by the amount of the transferred currency, and extinguishing the original currency existing in the sub-chain 612 is provided.

  The sub-chain 612 is made accessible to the network communication unit 321 of the smart lock device 3. This allows the sub-chain 612 to record ledger information associated with the unlocking of the smart lock device 3 at a higher speed than the main chain 611. It is possible to unlock the smart lock device 3 in a short time. In other words, the blockchain 61 with the sub-chain 612 responds to the request to open the “key” now, under the idea that the actual payment confirmation may be a little later if the credit is secured. , And a high degree of reliability is secured by the block chain of the sub-chain 612 itself.

(Recording device 6: block chain 61: main chain 611, sub-chain 612: operation)
4, the operation of the block chain 61 including the main chain 611 and the sub chain 612 will be described in detail.

  When the smart lock device 3 detects the smart device 4 (S11), the smart lock device 3 requests transmission of the user ID (S12), and the smart device 4 transmits the user ID (S13). Then, the smart lock device 3 releases the sub-chain 612 corresponding to the user ID (S14). That is, ledger information corresponding to the user ID is received from the main chain 611 (S15), asset information and user information are acquired from the ledger information (S16), and the user information is recorded in the sub-chain 612 (S17).

  Thereafter, the smart lock device 3 determines whether or not the unlock condition is satisfied based on the asset information, the user information, the credit information, the key information, and the like (S18). If the result of the unlocking determination is not proper (S19: NO), the smart device 4 outputs the improper information by voice or screen display (S20). On the other hand, if the result of the unlock determination is proper (S19: YES), the asset information and the user information are updated (S21), and the updated asset information is recorded in the main chain 611 (S23). The ledger information including the user information is recorded in the sub-chain 612 (S22).

  At this time, the sub-chain 612 does not depend on the block generation of the main chain 611 by being anchored to the main chain 611. As a result, since the sub-chain 612 generates blocks at a higher speed than the main chain 611, ledger information including user information is determined in a short time (S24). As a result, the smart lock device 3 that has detected the determination of the ledger information in the sub-chain 612 executes unlocking of the smart device 4 (S25 and S26). Thereafter, the asset information is determined by generating an information block in the main chain 611 (S27).

(Application example 1 of smart lock device 3)
Next, an application example of the smart lock device 3 will be described. A private night property in which the smart lock device 3 is introduced can easily issue a one-time key in conjunction with reservation on the private night platform. A guest who uses a private lodging can enter and leave only with the smart device 4 having his or her private key, or with a passcode only if permitted by the host. Also, the guest who has authenticated himself in the series of secret key acquisition processes can easily and easily perform the check-in process of any linked private lodging platform. This will be specifically described as follows.

  FIG. 5 shows an application example in which unlocking by the block chain 61 is performed by micropayment. For example, it is a case where the smart lock device 3 is attached to a general house. Specifically, the advance charge by the owner or the user is recorded in the main chain 611 of the block chain 61. Then, the owner and the user use the smart device 4 to immediately unlock the smart lock device 3 by settlement of the sub-chain 612. In this case, it is possible to unlock the smart lock device 3 using the block chain 61 without a central authority and to pay necessary expenses.

  FIG. 6 shows an application example in which a blockchain 61 provides a key to a trusted third party. For example, there are cases of private lodging, real estate preview, key lending to relatives, and the like. Specifically, the owner sets the use conditions (use fee, use period, number of uses, use time, etc.) based on the use contract with the user, and the service providing information processing apparatus 5 uses the main chain 611. To record. Thereafter, when the user performs an unlocking operation of the smart lock device 33 using the smart device 4, the unlocking is immediately performed by the sub-chain 612. Also, when the contract expires at the timing when the use information such as the use period and the number of uses reaches the use condition, and when the contract is used even after the contract expires, a warning of the contract expiration and stop of unlocking are set in the smart device 4. Is done. In this application example, the smart device 4 can easily provide a key valid for a certain period of time to a third party, for example, a guest in a private residence, which the key owner can trust.

  FIG. 7 is an application example in the case of cooperating with the reservation accommodation system (PMS) and the OTA (Online Travel Agent) in the application examples of FIG. 5 and FIG. 6, and enables a guest to enter the room more smoothly. In this case, by linking with the public key, the guest can enter and exit with the public key. In addition, a mechanism that simplifies the check-in process by checking whether the person who visits the facility on the same day as the passport information authenticated in advance and the same day is provided by a camera that links the key application and the smart lock device 3 Is done.

  Specifically, an electronic key can be received by a series of processes described below. Process (1) Make a reservation (public key cooperation using a public number such as a passport number or a driver's license number). Process (2) Cooperation of reservation information is performed. Process (3) The reservation is confirmed. Processing (4) Requests a ticket issuance (input: public key room ID, output: password). Process (5) Link the reservation result (including the password). Process (6) Inquire the reservation result (including the password). Process (7) Receive an electronic key.

(Distributed space rental exchange)
Next, when a space rental business is developed using the blockchain 61 of the recording device 6, a distributed space of an economic model in which a participant obtains a profit and a price is stabilized by the circulation (exchange) of a token which is a virtual currency. The rental exchange will be described.

  As shown in FIG. 9A, in the tokens that are distributed in the market, when the blockchain fund stores the tokens in the token pool (B1) and the guest (user) and the property owner start buying and selling and exchanging the tokens (B2 · B3). ), A token exchange between the blockchain fund, the guest and the property owner is executed at the virtual currency exchange (B4).

  Further, the blockchain fund has a token pool for the property owner (B5), and the property owner is given a token from the token pool for the property owner as a reward for introducing the smart lock device 3 (B6). ). When the guest pays a token to the property owner to use the property (B7, B8), the token is returned from the property owner to the guest for reuse (B9, 10).

  If the guest sells the token and settles it in cash currency (B11) when the token rises, the token falls (B12). On the other hand, if the guest purchases the token and settles it with the token (B13) when the token drops, the token increases (BS14).

  In addition, blockchain funds also have a token pool that encourages miners (B15). Thus, when the guest and the property owner mine, the token is obtained from the token pool as a reward (B16, B17).

  Note that, in order to stabilize the price of the token, trading may be performed in the procedure shown in FIG. 9B. Specifically, when the guest (user) and the property owner start buying and selling and exchanging tokens (B22, B23), the transaction between the blockchain fund and the virtual currency exchange is executed (B24).

  The blockchain fund acquires the transaction price of the token (B25). If the transaction price is lower than the assumed lower limit (reference value-predetermined value) (B26: YES), the token is purchased from the virtual currency exchange (B26). B27) Increase the value by reducing the circulation amount of the virtual currency. On the other hand, if the transaction price is higher than the assumed upper limit value (reference value + predetermined value) (B28: YES), a token is issued (B29), and the value is reduced by increasing the circulation amount of the virtual currency.

  In addition, the supply of virtual currency in the space rental business will be adjusted according to the market value of space and assets in cash currency (legal currency) using the AI algorithm of the “Real Estate Pegged Supply Mechanism (REPPS)” Is preferred. In this case, the volatility between the virtual currency and the cash currency (legal currency) can be reduced.

  To explain `` real estate pegged supply mechanism (REPPS) '' concretely, when designing a token that is a virtual currency, if the token quantity and its market capitalization and the total value of what you can buy with the token are the same, the price of the token will be Under the assumption of stability, we examined under what conditions the optimal amount of tokens could be calculated. As a result, in the sharing business using tokens, starting from the classic macroeconomic equation, the optimal token supply under the condition that the tokens are pegged to the real currency and the token circulation speed does not fluctuate greatly with time It is concluded that the amount is represented by the total amount of the assets being shared.

  In order to find the optimal supply of tokens, the monetary quantity theory (Fisher's exchange equation) is first expressed as follows.

Note that, in the monetary quantity theory (Fisher's exchange equation), the total purchase price and the total sales price of the entire economy match. Further, the following expression is made using the overall price level P and the individual relative prices P _{i, real} .

  Here, M (money amount) and Q (total amount of assets contributing to the network = total amount of rental space) are factors to be optimized. In designing the token, if P is pegged to real currency and the volume of distribution V is assumed to be a relatively constant value without incentive for users to trade frequently,

  Equation 4 is derived because M and Q are in a proportional relationship.

  Equation 4 shows that the appropriate token supply can be derived from the situation of the rental space being traded. Therefore, the optimal token supply amount according to each market situation is as follows.

  If the blockchain fund controls the supply of tokens (virtual currency) based on the algorithm based on the "Real Estate Pegged Supply Mechanism (REPPS)" above, reducing the volatility between tokens and cash currency (legal currency) Can be.

  In the above description of the decentralized space rental exchange, for convenience of explanation, the explanation was made with the guest (user), the property owner, the virtual currency exchange, and the blockchain fund as the main actors, but actually, the guest owns Smart device 4, service providing information processing device 5 owned by the property owner, virtual currency exchange exchange server, blockchain fund fund information processing device and pool server automatically make judgments and execute processing. Is what you do.

(Decentralized space rental exchange: specific configuration)
In the distributed space rental exchange, the unlocking operation of the smart lock device 3 that can be unlocked by wireless communication is performed by the smart device 4, and the ledger information accompanying the unlocking operation is recorded in the blockchain 61 using virtual currency (token). It is executed in a virtual currency distribution system for business use.

  The virtual currency distribution system includes a fund information processing device. The fund information processing device includes a distribution value acquisition unit that acquires a distribution value when virtual currency is exchanged for cash currency, a comparison unit that compares the distribution value with a reference value, and a virtual currency based on a comparison result in the comparison unit. And a fund control unit that purchases and issues virtual currency so as to bring the distribution value of the transaction closer to the reference value. That is, the fund control unit reduces the circulation amount of the virtual currency by purchasing the virtual currency when the value of the virtual currency is low, and issues the virtual currency by issuing the virtual currency when the value of the virtual currency is high. Increase the amount of currency circulation.

  In addition, the virtual currency distribution system has a service providing information processing device 5. The service providing information processing device 5 includes a virtual currency receiving unit that receives payment of virtual currency from the smart device 4, a cash currency receiving unit that receives payment of cash currency from the smart device 4, and payment of virtual currency or cash currency. And an unlocking operation unit for unlocking the smart lock device 3 by using the smart lock device 3 when at least a part of the virtual currency paid to the accepting unit is unlocked by the virtual currency. And a refund unit. The function of each unit in the service providing information processing apparatus 5 is provided by the API providing server 21 in FIG.

  Thereby, the virtual currency distribution system enables the unlocking of the smart lock device 3 by using either the virtual currency or the cash currency, and at the time of unlocking by the virtual currency, refunds at least a portion to the smart lock device 3. It is possible to promote the circulation of virtual currencies and stabilize the value of virtual currencies. It should be noted that the virtual currency distribution system may be arranged such that even when unlocking with cash currency, at least a part is refunded to the smart lock device 3 to reduce the price.

  Furthermore, in the virtual currency distribution system, when the value of the virtual currency increases, the smart device 4 exchanges the virtual currency for cash and pays the cash to the cash currency receiving unit. And a virtual currency payment unit for paying the virtual currency to the virtual currency receiving unit when the value decreases. As a result, unlocking of the smart lock device 3 is enabled by using either the virtual currency or the cash currency, and at the time of unlocking by the virtual currency, at least a part is refunded to the smart lock device 3. By exchanging the virtual currency for cash currency and unlocking the smart lock device 3 when the value of the virtual currency increases, circulation of the virtual currency can be promoted and the value of the virtual currency can be stabilized.
