The present invention is related to plant asset management; in particular, it refers to a plant asset management method, a plant asset management system, a plant asset trading method and a plant asset trading system for managing plant assets using blockchain technology.

The development of science and technology has brought many conveniences to human life. However, the concentration of greenhouse gases produced by exhaust gas emitted by factories and vehicles has also increased. Greenhouse gases mainly include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. Greenhouse gases will cause global warming, leading to global climate change, and have a considerable impact on the ecology and environment. At present, all countries in the world are committed to reducing greenhouse gas emissions.

Carbon dioxide is the most abundant greenhouse gas, and can be converted into oxygen through photosynthesis by plants. However, with the increase in population and the need for residential or industrial use, many lands that originally grew plants, such as forests and grasslands, have been destroyed by humans and converted into residential or industrial land, resulting in the current plants on Earth being insufficient to consume the large amount of carbon dioxide.

Although carbon dioxide can be consumed by planting large numbers of plants, the technology to manage the plants as assets has yet to be developed.

In view of this, the purpose of the present invention is to provide a plant asset management method and a plant asset management system that can treat planted plants as digital assets.

In order to explain the present invention more clearly, a preferred embodiment is given and described in detail with diagrams. Please refer to FIG1, which shows a plant asset management system 1 used in the plant asset management method of the first preferred embodiment of the present invention. The plant asset management system 1 operates in conjunction with a blockchain network 100. The blockchain network 100 includes a plurality of nodes 101. The plant asset management system 1 includes a management platform 10, a management node 20, and an issuer device 30.

The management platform 10 and the management node 20 may be, for example, a computer, a workstation, a server, or a cloud host. The issuer device 30 may be, for example, a mobile device, a computer, a workstation, a server, or a cloud host.

The management platform 10 is connected to the blockchain network 100 and is used to provide the issuer of the token with the content information of the token. The management platform 10 can be a node in the blockchain network 100, but is not limited to this and may not be a node in the blockchain network 100. The management platform 10 provides token owners with smart contracts corresponding to the tokens for management.

The management node 20 is a node 101 in the blockchain network 100. The management node 20 deploys a smart contract corresponding to the token for each node 101 in the blockchain network 100. The smart contract contains the management restrictions of the corresponding token. The management restrictions of the smart contract may include: 1. Query the content information of the token; 2. The token owner can add and update the content information of the token; 3. The authorized third party can add, query and update a part of the content information of the token (such as a change information); 4. The owner can transfer and destroy the token he owns; 5. The authorized third party can transfer the token to the new owner and set the transfer quantity. In practice, the smart contract can also be designed to provide other appropriate management functions.

The issuer device 30 is operated by the token issuer and can be connected to the management platform 10 to set the content information of the token on the management platform 10 for issuance. In this embodiment, the issuer device 30 is independent of the blockchain network 100 and can be connected to the blockchain network 100 through the management platform 10, but it is not limited to this. The issuer device 30 can also be a node 101 in the blockchain network 100.

The plant asset management system 1 further includes an owner device 40, which is operated by the token owner and can be connected to the management platform 10 to interact with the smart contract corresponding to the token to manage the owned token. The owner device 40 can be, for example, a mobile device, a computer, a workstation, a server, or a cloud host. In this embodiment, the owner device 40 is independent of the blockchain network 100 and can be connected to the blockchain network 100 through the management platform 10, but it is not limited to this. The owner device 40 can also be a node 101 in the blockchain network 100.

The plant asset management method of this embodiment includes the following steps as shown in Figure 2:

Step S11: Divide a plurality of plants in at least one plant planting area into a plurality of units. In this embodiment, the plants are trees, but are not limited thereto, and may also be plants capable of photosynthesis such as bamboo and grass. The plants in the planting area may also be a mixture of different plants.

The plant planting area is located in a region, and the trees planted in the plant planting area can be a single tree species or a mixture of multiple different tree species. In one embodiment, the plants in multiple plant planting areas can be collectively divided into multiple units, and these plant planting areas can be located in the same region, or in different regions, or even in different countries.

In addition, when dividing, the volume, number of trees, and area of the planting area can be used to divide the units. In this embodiment, the volume (or timber volume) of the trees is used to divide the units. For example, the total volume of multiple trees in at least one plant planting area is measured, and then the total volume is divided into multiple units. Preferably, the total volume of multiple trees of the same tree species is divided into multiple units, for example, each unit is 1 cubic meter, but not limited to this, and each unit can also be 2 cubic meters or more. Each unit can be called a volume unit or a timber unit

In one embodiment, when dividing by the number of trees, each unit has one tree, but it is not limited to this, and each unit may have more than 2 trees.

In one embodiment, when the planting area is divided by area, each unit is the number of trees in a specific planting area, and the specific planting area may be, for example, 1 square meter, or more than 2 square meters.

Step S12: deploy a smart contract on the blockchain network 100, and establish content information of at least one token through the smart contract and issue the token, wherein the token corresponds to one or more units divided in step S11. The content information includes the owner information of the token, the number of units corresponding to the token (i.e. the number of units held), and the information of the plants corresponding to the units. The content information may further include the total issuance quantity of these units. The information of the plants may be, for example, the market price of the tree species and the unit corresponding to the token, and may also include the age of the tree, the planting area, the planting quantity, the carbon fixation amount, the management team, the management fee, etc. The content information may also include variable information, which includes annual planting environment records, quantitative growth data (i.e. plant growth data), increase or decrease in carbon fixation, current market price, etc. When issuing a token, the issuer can set the owner of the token to be himself or others.

For example, the token corresponds to one unit, but not limited to more than 2 units, for example, one token corresponds to 10 units.

In this embodiment, the issuer and owner of the token respectively register with the management node 20 to obtain an account and generate a private key and a public key corresponding to the account. The private key of the issuer is held by the issuer, and the public key of the issuer is sent to all nodes. The private key of the owner is held by the owner, and the public key of the owner is sent to all nodes 101. For example, you can register with the management node 20 through the management platform 10, or directly connect to the management node to register.

The issuer logs into the management platform 10 with its account through the issuer device 30 to set the content information of the token, and the issuer device 30 signs an issuance request with a private key and transmits the issuance request to the management platform 10.

The management platform 10 receives the issuance request and the content information, and transmits the issuance request and the content information from the issuer device 30 to the management node 20. The management node 20 verifies the issuance request with the corresponding public key, and after the verification is correct, deploys the smart contract of the corresponding token and issues the corresponding token according to the content information.

Step S13: Add the at least one token and its content information to the distributed ledger 101a of the nodes 101 in the blockchain network 100.

In this embodiment, the management node 20 adds or updates the smart contract, token and its content information to the distributed ledger 101a of each node 101 in the blockchain network 100.

Through the above steps, the issuance of plant tokens is completed, turning physical plants into digital assets.

The above description uses the issuance of one token as an example. In other embodiments, multiple tokens can also be issued through the smart contract.

Afterwards, a query step and/or an update step may be optionally performed.

The query step includes the following steps: a query device sets a token query condition, and the query device sends a query request to the management node 20 according to the token query condition; the management node 20 queries the smart contract according to the token query condition, and sends the query result to the query device.

In this embodiment, the query device can be any node 101 on the blockchain network 100 or other devices, such as the owner device 40 or the issuer device 30.

Taking the query device as an example, the owner device 40, the token owner logs into the management platform 10 with his account to set the token query condition, which can be any one or more information in the content information. The owner device 40 (query device) signs the query request with a private key and sends it to the management platform 10. The query request includes the token query condition. The management platform 10 receives the query request and sends it to the management node 20. The management node verifies the query request with the corresponding public key, and after verification, performs a query according to the token query condition through a smart contract, and transmits the query result to the owner device 40 through the management platform 10. For example, the token query condition is to query the owner information in the content information of the token, and the query result is the token and its content information that meets the owner information.

If the queried token is owned by the token owner, the owner device 40 can interact with the smart contract corresponding to the owned token to manage the owned token, such as updating the content information of the token.

Taking the issuer device 30 as an example, the querying steps are the same, except that the private key used for signing and the public key used for verification are different. Similarly, if the queried token is owned by the issuer, the issuer device 30 can also interact with the smart contract corresponding to the token to manage the token.

If the query device is any node 101 on the blockchain network 100, the query device communicates directly with the management node 20 without sending the query request and query result through the management platform 10.

The update step includes the following steps: an update device sets the new content information of the at least one token and sends an update request to the management node 20. The management node 20 updates the new content information of the at least one token to the distributed ledger 101a of the nodes 101 through the smart contract.

In this embodiment, the update device can be any node 101 on the blockchain network 100 or other devices, such as the owner device 40 or the issuer device 30.

Taking the issuer device 30 as an example, the token issuer uses the issuer device 30 to log in to the management platform 10 with its account to set the new content information of the token to be updated, so as to change any one or more of the content information. The issuer device 30 (update device) signs the update request with a private key and sends it to the management platform 10. The update request includes the new content information of the token to be updated. The management platform 10 receives the update request and sends it to the management node 20. The management node 20 verifies the update request with the corresponding public key, and after the verification is correct, updates the new content information of the token to the distributed ledger 101a of the nodes 101 on the blockchain network 100 through a smart contract. The management node 20 then transmits the updated result to the issuer device 30 via the management platform 10.

Taking the owner device 40 as an example, the updating steps are the same, except that the private key used for signing and the public key used for verification are different.

If the update device is any node 101 on the blockchain network 100, the update device communicates directly with the management node 20 without sending the update request and update result through the management platform 10.

The issuer device 30 and the owner device 40 each have a wallet. Each wallet is an example of a wallet address on the blockchain network 100, but is not limited thereto and may also be a cold wallet. The wallet of the issuer device 30 is linked to the tokens owned by the issuer and their content information, and the wallet of the owner device 40 is linked to the tokens owned by the owner and their content information. The issuer and the owner can view the wallets on their respective issuer devices 30 and owner devices 40 to know the tokens they own and their content information.

In addition to issuing plant tokens, a carbon right certification agency may also evaluate the plants in the at least one plant planting area and certify the carbon rights of the plants to convert the plants into a corresponding plurality of carbon right units (i.e., first carbon right units). Then, a plurality of carbon right tokens (i.e., first carbon right tokens) are issued on the blockchain network 100. These first carbon right tokens correspond to these first carbon right units. For example, the issuer device 30 sets a content information of the first carbon right token through the management platform 10. The content information of each first carbon right token includes the quantity and owner of its carbon right unit. For example, the management node 20 issues some first carbon rights tokens through a carbon rights smart contract, and adds these first carbon rights tokens and their content information to the distributed ledger 101a of the nodes 101 in the blockchain network 100. In addition, the wallet of the issuer device 30 is linked to these first carbon rights tokens. The issuer can check the wallet on the issuer device 30 to know the first carbon rights tokens and their content information. In this way, in addition to obtaining the tokens of the plants, the carbon rights derived from the plants can also be obtained.

FIG3 shows a plant asset management system 2 of the second preferred embodiment of the present invention, which has a substantially similar structure to the first embodiment, except that the issuer device 30 and the owner device 40 are each a node 101 on the blockchain network 100, and therefore, there is no need to connect to the blockchain network 100 via the management platform 10.

The plant asset management method of this embodiment is roughly the same as that of the first embodiment, except that in step S12, the issuer sets the content information of the token on the issuer device 30, and after the issuer device 30 signs an issuance request with a private key, the issuance request and the content information are transmitted to the management node 20. The management node 20 verifies the issuance request with the corresponding public key, and after the verification is correct, deploys the corresponding token smart contract and issues the corresponding token according to the content information.

In this way, the plant token can be issued without going through the management platform 10. Similarly, the query step and the update step do not need to go through the management platform 10. In this embodiment, the carbon rights token can also be issued without going through the management platform 10.

FIG4 shows the plant asset management method of the third preferred embodiment of the present invention, which is based on the first embodiment and further includes after step S13:

Step S14: After a period of time, obtain a growth increment of the plants in the at least one plant planting area compared to step S11, and divide the growth increment into one or more units.

In this embodiment, since the plants will continue to grow, the total volume of multiple trees in the plant planting area can be measured in step S11, and then in step S14, after a period of time, such as one season, half a year, or one year, or two years, the total volume of multiple trees in the plant planting area is measured again after the plants grow, so as to obtain the growth increment of the plants compared with step S11, that is, the increase in the total volume. The more the growth increment, the more units are obtained by division, and the division method is synchronized with step S11.

Step S15: Create content information of at least one other token through the smart contract and issue the other token, wherein the other token corresponds to one or more units divided by the growth increment; the content information of the other token includes owner information, the quantity of the unit corresponding to the other token, and information of the plant of the corresponding unit. The content information of the other token is the same as the content information of the token of the first embodiment.

In this embodiment, the issuer logs into the management platform 10 with its account through the issuer device 30 to set the content information of the other token, and the issuer device 30 signs an issuance request with a private key and transmits the issuance request to the management platform 10.

The management platform 10 receives the issuance request and the content information, and transmits the issuance request and the content information from the issuer device 30 to the management node 20. The management node 20 verifies the issuance request with the corresponding public key, and after the verification is correct, deploys the corresponding smart contract and issues the corresponding other token according to the content information.

In practice, the issuer device 30 can also be a node 101 on the blockchain network 100. The issuer sets the content information of the other token on the issuer device 30, and after the issuer device 30 signs the issuance request with a private key, the issuance request and the content information are transmitted to the management node 20. The management node 20 verifies the issuance request with the corresponding public key, and after the verification is correct, deploys the corresponding smart contract and issues the corresponding other token according to the content information. In this way, the other token can be issued without going through the management platform 10.

Step S16: Add the other token and its content information to the distributed ledger 101a of the nodes 101 in the blockchain network 100.

In this embodiment, the management node 20 adds or updates the smart contract, the other token and its content information to the distributed ledger 101a of each node in the blockchain network 100.

Through the above steps, the issuance of tokens after plant growth is completed, and the growth increment of physical plants is transformed into digital assets.

In addition, in this embodiment, a carbon right certification agency may also evaluate and certify the carbon rights of the plants grown in the at least one plant planting area. By comparing the carbon rights before plant growth and the carbon rights after growth, the carbon rights corresponding to the growth increment can be obtained, and the growth increment of the plants is converted into a corresponding plurality of carbon right units (i.e., second carbon right units). Then, a plurality of carbon right tokens corresponding to the growth increment (i.e., second carbon right tokens) are issued on the blockchain network 100. These second carbon right tokens correspond to these second carbon right units. For example, the issuer device 30 sets a content information of the second carbon right token through the management platform 10. The content information of each second carbon right token includes the quantity and owner of its second carbon right unit. The management node 20 then issues some second carbon rights tokens through a carbon rights smart contract, and adds these second carbon rights tokens and their content information to the distributed ledgers of the nodes 101 in the blockchain network 100. In addition, the wallet of the issuer device 30 is linked to these second carbon rights tokens. The issuer can check the wallet on the issuer device 30 to know the carbon rights tokens (second carbon rights tokens and/or first carbon rights tokens) it owns and the content information of the carbon rights tokens.

This embodiment can also perform the query step and/or the update step as in the first embodiment to query and/or update the at least one additional token issued incrementally. And the plant asset management method of this embodiment can also be applied to the second embodiment.

In the above, the additional at least one token issued incrementally is taken as an example, but in practice it can be multiple tokens.

FIG5 shows a plant asset management system 4 of the fourth preferred embodiment of the present invention, which is based on the first embodiment. The management platform 10 is further connected to a plant market price public information platform 50, which can be provided by a competent authority for plant management (such as the Forestry Bureau) or a third-party notary agency.

The plant asset management method of this embodiment includes: the management platform 10 obtains the market price of the plants from the plant market price public information platform 50 and calculates the market price of each unit according to the market price of the plants, and records it in the content information of the token. When the token is issued, the market price is recorded in the content information. The issuer can use the issuer device 30 to regularly use the update step to update the market price to the change information in the content information of the token, or authorize it to a third party, and the authorized third party regularly uses the update step to update the market price to the change information of the content information of the token. In this way, it is easier to understand the changes in the market price of the plant corresponding to the token.

The plant management method and plant management system of the present invention can divide plants into multiple units and issue corresponding tokens on the blockchain network, turning the plants in the planting area into digital assets. The tokens can be queried, updated, and even traded later.

FIG6 shows a plant asset trading system 5 used in the plant asset trading method of the fifth preferred embodiment of the present invention. The plant asset trading system 5 also operates in conjunction with the blockchain network 100. The plant asset trading system 5 is substantially the same as the plant asset management system 1 of the first embodiment, and includes the management node 20, a trading platform 60, a supplier device 70, and a demander device 80. In this embodiment, the plant asset trading system 5 can operate in conjunction with the plant asset management system 1 of the first embodiment to form a plant asset management and trading system.

The trading platform 60 can be, for example, a computer, a workstation, a server, or a cloud host. The trading platform 60 is connected to the blockchain network 100 and can be connected to the supplier device 70 and the demander device 80. The trading platform 60 is used to provide the token supplier (i.e., the seller or owner) and the demander (buyer) with the token sales information and the token's historical transaction price information, or transaction matching information and the token's market price information. The trading platform 60 can be a node 101 in the blockchain network 100, but is not limited to this, and may not be a node 101 in the blockchain network 100. In this embodiment, the trading platform 60 and the management platform 10 are located on two hosts respectively, but are not limited to this, and can also be integrated on one host.

The supplier device 70 is operated by the supplier of the token and can be connected to the trading platform 60 to set a sales information, which includes the token to be sold and the price to be sold. In this embodiment, the supplier device 70 is independent of the blockchain network 100 and can be connected to the blockchain network 100 through the trading platform 60, but it is not limited to this. The supplier device 70 can also be a node 101 in the blockchain network 100. When the issuer device 30 or the owner device 40 wants to sell the token and connects to the trading platform 60 to set the sales information, the issuer device 30 or the owner device 40 becomes the supplier device 70. The wallet of the supplier device 70 is defined as a first wallet.

The demander device 80 is operated by the demander of the token and can be connected to the trading platform 60 to set a transaction request. The demander device 80 can be, for example, a mobile device, a computer, a workstation, a server, or a cloud host. In this embodiment, the demander device 80 is independent of the blockchain network 100 and can be connected to the blockchain network 100 through the trading platform 60, but it is not limited to this. The demander device 80 can also be a node 101 in the blockchain network 100. When the issuer device 30 or the owner device 40 wants to purchase a token and connects to the trading platform 60, the issuer device 30 or the owner device 40 becomes the demander device 80. The wallet of the demand-side device 80 is defined as a second wallet.

The plant asset transaction method of this embodiment includes the following steps as shown in Figure 7:

Step S21: Divide a plurality of plants in at least one plant planting area into a plurality of units.

Step S22: Create content information of each of a plurality of tokens on a blockchain network 100 and issue the tokens, wherein each token corresponds to one or more units divided in step S21, and each content information includes the quantity of the unit corresponding to each token and the information of the plant of the corresponding unit.

Step S23: Add each of the tokens and its content information to the distributed ledger 101a of the nodes 101 in the blockchain network 100.

In this embodiment, the above steps S21 to S23 are substantially the same as those in the first embodiment, except that this embodiment uses the issuance of multiple tokens as an example, but is not limited thereto and may also be at least one token.

Step S24: Set a sales information, which includes the token to be sold and the price to be sold. In this embodiment, the supplier of the token is the issuer or owner, who has registered an account with the management node 20 and has generated a private key and a public key. The demander also registers with the management node 20 to obtain an account and generates a private key and a public key. For example, you can register with the management node 20 through the management platform 10, or directly connect to the management node 20 to register. The trading platform 60 obtains the account information of the supplier and the demander from the management platform 10.

The supplier device 70 sets the sales information and a transaction restriction in a transaction smart contract through the transaction platform 60 on the management node 20. Specifically, the supplier logs in to the transaction platform 60 with his account through the supplier device 70, sets the sales information and the transaction restriction in the transaction smart contract, and signs it with his private key, which is then transmitted to the management node by the transaction platform 60. The management node 20 verifies the sales information and the transaction restriction with the corresponding public key, and deploys the corresponding token transaction smart contract after verification, and publishes the transaction smart contract to the distributed ledger 101a of the nodes 101 in the blockchain network 100. The transaction restriction may, for example, limit the resale price, the number of resales, the resale feedback ratio, etc., but is not limited to this.

The sales information is then released. The sales information can be released, for example, by the supplier device 70 on the trading platform 60, or by the trading platform 60 actively releasing the sales information after the management node 20 verifies that the sales information is correct, or by the supplier releasing the sales information on its own, such as on a social networking site or using a communication software.

Step S25: Set a transaction request to conduct a transaction. In this embodiment, the demander logs in to the trading platform 60 with its account through the demander device 80 to set the transaction request and signs it with its private key, which is then transmitted to the management node 20 by the trading platform 60. The management node 20 verifies the transaction request with the corresponding public key, and after the verification is correct, notifies the trading platform 60 to conduct the transaction. The management node 20 executes the transaction request through the transaction smart contract. In addition, the transaction smart contract can further determine whether the number of token units is sufficient and/or meets the transaction restrictions. When the number of token units is sufficient and/or meets the transaction restrictions, the transaction is allowed.

In this embodiment, before the demander device 80 sets the transaction request, the demander uses the demander device 80 to connect to the trading platform 60 to query the published sales information. The trading platform 60 obtains the content information and sales information of the token from the management node 20 and transmits them to the demander device 80. The demander checks the sold token, its content information and the selling price to decide whether to purchase it.

In this embodiment, the trading platform 60 can obtain the historical transaction price of the token corresponding to the sales information from the management node 20. If the token has been traded before, its historical transaction price can be obtained and published on the trading platform 60, even the trend of the historical transaction price, or further predicted price. The demand side device 80 connects to the trading platform 60 to query the published historical transaction price, and/or the trading platform transmits the historical transaction price to the demand side device 80 for the demand side to view.

After the demander decides to purchase, the demander device 80 is operated to set the transaction request to conduct the transaction. In this embodiment, the demander conducts the transaction through financial transfer, but it is not limited to this. Specifically, the trading platform 60 is connected to a financial service host 90, which is used to provide financial transfer services. The demander transfers the amount of the demander's account to the supplier's account through the financial service host 90. The financial service host 90 generates a transfer information after the financial transfer of the transaction is completed, and transmits the transfer information to the trading platform 60. After receiving the transfer information, the trading platform 60 transmits a transaction completion message to the management node 20, indicating that the transaction has been completed. The transaction completion message can be a token transfer request.

Step S26: After the transaction is completed, a transaction information is generated, which includes the traded token, the transaction price, a supplier information and an owner information; and a token transfer step is performed to transfer the traded token to the demander.

In this embodiment, after the management node 20 receives the transaction completion message from the trading platform 60, it generates the transaction information and performs the token transfer step according to the transaction information.

The token transfer step includes: updating the transaction information to the content information of the corresponding token, and updating it to the distributed ledger 101a of the nodes 101 in the blockchain network 100. Specifically, the management node 20 updates the transaction information to the content information of the corresponding token through the transaction smart contract, and updates it to the distributed ledger 101a of the nodes in the blockchain network 100.

Through the above steps, in addition to converting physical plants into digital assets, digital assets can also be traded.

In the token transfer step of this embodiment, one or more carbon rights tokens corresponding to the traded tokens are transferred from the first wallet of the supplier device 70 to the second wallet of the demander device 80. In this way, the demander not only obtains the plant tokens, but also obtains the corresponding number of carbon rights tokens.

In addition, after the demander obtains the token, he can also become a supplier and sell the token again, and perform the above steps S24~S26. The original demander device 80 becomes the new supplier device 70.

In one case, if the second wallet of the demand side device 80 has a carbon rights token, then in the above step S15, the financial service host 90 does not need to provide financial transfer services, and the carbon rights token can be directly used to complete the transaction. More specifically, in step S15, the demand side operates the demand side device 80 to transfer at least a portion of the carbon rights tokens in the second wallet to the first wallet, and the carbon rights tokens transferred in the above are equivalent to the price of the plant token to be sold. After the carbon rights token is transferred, the supplier device 70 or the supplier device 70 generates a transfer information and transmits it to the trading platform 60, and the trading platform 60 transmits a transaction completion message to the management node 20.

In this way, the demander can use the carbon rights tokens they own as the currency for transactions to purchase plant tokens.

In the fifth preferred embodiment described above, the transaction between the supplier and the demander is explained by the method of purchase. The following provides a sixth preferred embodiment of the plant asset transaction method, which is a matchmaking method. The sixth preferred embodiment of the present invention has the same steps and system architecture as the fifth embodiment, except that:

Step S24: The supplier device 70 sets a sales information on the management node 20 through the trading platform. The sales information includes the token to be sold, the quantity of units corresponding to the token to be sold, and the price to be sold.

Step S25: The transaction request set by the demand-side device 80 on the trading platform 60 includes a purchase information, which includes the token to be purchased, the quantity of the unit to be purchased, and the price to be purchased. The trading platform 60 conducts the transaction based on the sales information and the purchase information. The trading platform 60 generates transaction matching information and market price information to conduct transactions, such as competitive bidding. After the transaction is completed, the trading platform 60 sends a transaction completion message to the management node 20, indicating that the transaction has been completed.

In this embodiment, if the second wallet of the demand-side device 80 has a carbon rights token, then in the above step S25, the financial service host 90 does not need to provide financial transfer services, and the transaction can be completed directly by transferring the carbon rights token.

FIG8 shows a plant asset trading system 7 of the seventh preferred embodiment of the present invention, which has a structure substantially similar to that of the fifth embodiment, except that the supplier device 70 and the demander device 80 are respectively nodes 101 on the blockchain network 100, and therefore, do not need to be connected to the blockchain network 100 through a trading platform.

The steps of the plant asset transaction method of this embodiment are roughly the same as those of the fifth embodiment, except that:

In step S24, the supplier connects to the management node 20 through the supplier device 70 to set the sales information and the transaction restrictions to the transaction smart contract. The management node 20 publishes the transaction smart contract to the distributed ledger 101a of the nodes 101 in the blockchain network 100.

After that, the sales information is released for the demand side device 80 to view. The way of releasing the sales information can be, for example, the supply side device 70 connects to the trading platform 60 and releases the sales information on the trading platform, or the trading platform 60 actively releases the sales information after the management node 20 verifies that it is correct, or the supply side releases the sales information by itself.

In step S25, the demander sets a transaction request through the demander device 80 and submits the transaction request to the supplier device 70. For example, the demander device 80 signs the transaction request with its private key and transmits it to the management node 20. The management node 20 verifies the transaction request with the corresponding public key and notifies the demander device 80 after the verification is correct. The management node 20 executes the transaction request through the transaction smart contract. After the demander device 80 accepts the transaction request, it signs and confirms it with its private key. After the management node 20 verifies it with the corresponding public key, it notifies the demander device 80 to conduct the transaction. For example, the demander device 80 can connect to the financial service host 90 through the transaction platform 60 and conduct the transaction through financial transfer. The financial service host 90 generates a transfer information after the financial transfer of the transaction is completed, and transmits the transfer information to the trading platform 60. After receiving the transfer information, the trading platform transmits a transaction completion message to the management node 20, indicating that the transaction has been completed.

Afterwards, the management node 20 receives the transaction completion message from the trading platform, generates the transaction information, and performs the token transfer step according to the transaction information, thereby completing the token transaction.

FIG9 shows a plant asset management system 8 used in the plant asset management method of the eighth preferred embodiment of the present invention, which has a structure substantially similar to that of the first embodiment, and further includes an update device A0 connected to the management platform 10. The update device A0 is connected to the management node 20 through the management platform 10 to set the growth data of the plants corresponding to each token.

In this embodiment, the update device A0 is operated by a third-party notary agency, and the update device A0 can be, for example, a mobile device, a computer, a workstation, a server, or a cloud host. The third-party notary agency is responsible for measuring the growth status of plants in the plant planting area to obtain the growth data. In this embodiment, the total volume of trees is measured as an example, but it is not limited to this. The update device A0 can be any node 101 on the blockchain network 100 or other devices. The third-party notary agency first registers with the management node 20 to obtain an account and generates a private key and a public key corresponding to the account. For example, it can register with the management node 20 through the management platform 10, or directly connect to the management node 20 to register. The update device A0 signs the request with a private key, and the management node 20 verifies the request with a public key, which is the same as the above-mentioned embodiments and will not be described in detail later.

The plant asset management method of this embodiment is similar to the third embodiment, and includes the following steps shown in FIG. 10.

Step S31: Provide at least one token in the blockchain network 100, and the distributed ledger 101a of the node 101 of the blockchain network 100 records the at least one token and its content information.

In this embodiment, the issuance of a token is taken as an example, but it is not limited to this, and multiple tokens can also be issued. The steps of issuing a token are the same as those of the first embodiment. The issuer device 30 sets the content information of the token and sends an issuance request to the management node 20 through the management platform 10. The management node 20 issues the token through the smart contract and adds the token and its content information to the distributed ledger 101a of the nodes in the blockchain network 100. In this embodiment, the change information of the content information records the growth data of the plants when they are divided into units. For example, the growth data is given to the issuer by a third-party notary agency, and the issuer sets the initial growth data in the change information.

In addition, the issuer device 30 is further connected to the management node 20 to set an update permission for the update device A0 in the smart contract. The update permission allows the update device A0 to set the growth data of the plants corresponding to the token.

Step S32: Obtain a growth increment of the plants in the plant planting area.

In this embodiment, the third-party notary agency measures the growth data of the plant at regular intervals, such as one season, half a year, one year, or two years, such as measuring the total volume of the current plant, and the update device A0 sets the growth data in the smart contract through the management platform 10 or directly connects to the management node 20. More specifically, the third-party notary agency logs in to the management platform 10 with its account through the update device A0 to set the growth data corresponding to the content information of the token, and sends an update request and growth data to the management node 20. The management node 20 updates the growth data to the distributed ledger 101a of the nodes 101 through the smart contract, and the management node 20 sends a notification message to the issuer device 30 to notify the issuer that the growth data of the token has been updated.

The issuer device 30 is connected to the management node 20 and generates the growth increment according to the growth data and sets the growth increment in the smart contract. More specifically, the issuer connects to the management node 20 through the management platform 10 to query the growth data in the token change information, and calculates the growth increment according to the difference between the latest growth data and the previous growth data, but not limited to this, the smart contract can also automatically calculate the growth increment according to the difference between the latest growth data and the previous growth data. The more growth increments there are, the more units can be obtained in the subsequent division.

Step S33: Create content information of at least one other token on the blockchain network 100 and issue the other token, wherein the other token corresponds to one or more units divided by at least a portion of the growth increment. The content information of the other token includes the quantity of the unit corresponding to the other token and the information of the plant of the corresponding unit.

Step S33 of this embodiment is the same as step S15 of the third embodiment. The issuer divides the growth increment into one or more units. The issuer device 30 sets the content information of the other token and transmits the issuance request and the content information to the management node 20 through the management platform 10, and issues another token through the smart contract.

Step S34: Add the other token and its content information to the distributed ledger 101a of the nodes 101 in the blockchain network 100.

In this embodiment, the management node 20 adds or updates the smart contract, the other token and its content information to the distributed ledger 101a of each node 101 in the blockchain network 100.

Through the above steps, the issuer can issue additional tokens for all growth increments after the plant grows.

In this embodiment, in step S31, a carbon right certification agency can also evaluate and certify the carbon rights of the plants in the at least one plant planting area as in the first embodiment, so as to convert the plants into corresponding multiple carbon right units (i.e., first carbon right units). Then, multiple carbon right tokens (i.e., first carbon right tokens) are issued on the blockchain network 100, and the first carbon right tokens correspond to the first carbon right units. For example, the management node 20 issues the first carbon right tokens through a carbon right smart contract, and adds the first carbon right tokens and their content information to the distributed ledger 101a of the nodes 101 in the blockchain network 100. The wallet of the issuer device 30 is linked to the first carbon right tokens.

After step S32, as in the third embodiment, a carbon right certification agency may evaluate and certify the carbon rights of the plants grown in the at least one plant planting area. By comparing the carbon rights before and after plant growth, the carbon rights corresponding to the growth increment can be obtained, and the growth increments of the plants are converted into a corresponding plurality of carbon right units (i.e., second carbon right units). Then, a plurality of carbon right tokens (i.e., second carbon right tokens) are issued on the blockchain network 100, and these second carbon right tokens correspond to these second carbon right units. For example, the management node 20 issues some second carbon right tokens through a carbon right smart contract, and adds these second carbon right tokens and their content information to the distributed ledger 101a of the nodes 101 in the blockchain network 100. In step S34, the wallet included in the issuer device 30 is linked to the second carbon rights tokens.

In practice, the issuer device 30 can also be a node 101 on the blockchain network 100, which can directly transmit the issuance request and the content information to the management node 20, thereby issuing the other token without going through the management platform 10. The update device A0 can also be a node 101 on the blockchain network 100, which can directly transmit the update request and growth data to the management node 20.

FIG11 shows a plant asset trading system 8a used in the plant asset trading method of this embodiment, which is based on the aforementioned plant asset management system 8, and is combined with a trading platform 60, a supplier device 70 and a demander device 80 similar to the fifth embodiment, the difference being that the issuer device 30 in this embodiment becomes the supplier device 70, and the other token issued by selling the corresponding growth increment.

The plant asset transaction method of this embodiment includes the following steps as shown in FIG. 12, which is based on the plant asset management method of this embodiment, has the same steps S31~S34, and further includes:

Step S35: Set a sales information, which includes the other token to be sold and the price to be sold; publish the sales information for a transaction.

Step S36: Set a transaction request and conduct a transaction.

In addition, this embodiment further includes step S37: after the transaction is completed, a transaction information is generated, the transaction information includes the at least one other token traded, the transaction price, a supplier information and an owner information; and a token transfer step is performed; wherein the token transfer step includes: updating the transaction information to the corresponding content information of the at least one other token, and updating it to the distributed ledger 101a of the nodes in the blockchain network.

The above steps S35 to S37 are respectively the same as the steps S24 and S26 of the fifth embodiment. The only difference is that the subject of the sale is the other token, so the steps can be used and will not be repeated. In the token transfer step, the corresponding second carbon rights token can be transferred to the wallet of the demand-side device 80 as in the fifth embodiment.

In addition, the transaction of the other token can also be conducted in a matching manner as in the sixth embodiment.

In addition, the issuer device 30 and the demander device 80 of this embodiment can also be a node 101 on the blockchain network 100 respectively. In this way, the plant asset trading method and the plant asset system can be the same as the seventh embodiment, without connecting to the blockchain network 100 through the trading platform, and steps S35~S36 can use steps S24 and S25 in the seventh embodiment.

FIG. 13 shows the plant asset management method of the ninth preferred embodiment of the present invention, which has substantially the same steps as the eighth embodiment and is also applicable to the plant asset management system 8. The difference is that the other token issued in step S33 of this embodiment is a unit divided by the corresponding portion of the growth increment, rather than a unit divided by the entire growth increment.

In more detail, step S33 includes updating a change information in the content information of the at least one token in the distributed ledger 101a of the nodes 101 on the blockchain network 100, wherein the change information includes the quantity of an incremental unit, and the quantity of the incremental unit corresponds to a portion of the growth increment. The content information of the other token is established on the blockchain network 100 and the other token is issued, wherein the other token is one or more of the units divided corresponding to another portion of the growth increment.

In the above, a distribution ratio is set in the smart contract, and the smart contract divides the growth increment into a first part and a second part according to the distribution ratio. The number of the incremental units corresponds to the growth increment of the first part, that is, the smart contract generates the incremental units of the change information based on the growth increment of the first part and the number of the original units of the token. The more the number of the original units of the token, the more incremental units are obtained. The management node 20 updates the number of the incremental units of the change information of the original token to the distributed ledger 101a of the nodes 101 through the smart contract. In this way, the total number of units of the original token is increased, and the total unit is the number of units of the token plus the number of the incremental units, so that the token can increase in value as the plant grows.

The additional token issued in increments corresponds to the unit divided by the growth increment of the second part. That is, the issuer device 30 obtains the growth increment of the second part from the management node 20, and divides the growth increment of the second part into one or more units. The issuer device 30 connects to the management node 20 to establish the content information of the additional at least one token in the smart contract and issue the additional at least one token.

In this way, part of the growth increment can be converted into the incremental unit of the original token, and the issuer of the other part of the growth increment token can reissue at least one more token, and then sell the at least one more token, so that the owner and issuer of the original token can have room to profit according to the growth of the plant. And the owner and issuer can obtain the carbon right token corresponding to the growth increment in the wallet of their respective devices, representing the carbon right of the plant.

In practice, the issuer device 30 can also be a node 101 on the blockchain network 100, which can directly transmit the issuance request and the content information to the management node 20, thereby issuing the other token without going through the management platform 10. The update device A0 can also be a node 101 on the blockchain network 100, which can directly transmit the update request and growth data to the management node 20.

The plant asset trading method of this embodiment is based on the above-mentioned plant asset management method and plant asset management system. The other steps and plant asset trading system are the same as those of the eighth embodiment. The equivalent implementation changes are also the same as those of the eighth embodiment and will not be repeated.

The above is only the preferred feasible embodiment of the present invention. Any equivalent changes made by applying the present invention specification and the scope of patent application should be included in the patent scope of the present invention.
