The management platform 10 is connected to the blockchain network 100 and is used to provide the issuer of a token (Token) with content information to set the token. The management platform 10 may 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 the token owner with the ability to interact with the smart contract corresponding to the token 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 includes The management restrictions of the corresponding token. The management restrictions of smart contracts may include: 1. Query the content information of the pass; 2. The owner of the pass can add and update the content information of the pass; 3. An authorized third party can access part of the content information of the pass (For example, a change of information) Add, query and update; 4. The owner can transfer and destroy the token he owns; 5. An authorized third party can transfer the token to a new owner and set up the transfer quantity. In practice, smart contracts 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. However, this is not a limitation. The issuer device 30 can also be connected to the blockchain network 100. It can be a node 101 in the blockchain network 100.

The plant asset management system 1 also includes an owner device 40. The owner device 40 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 of the pass. The owner device 40 may 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. However, this is not a limitation. The owner device 40 can also be connected to the blockchain network 100. It can be a node 101 in the blockchain network 100.

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

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

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

In addition, when dividing, the volume, number of trees, and area of the planting area of the plurality of trees can be used to divide the unit into the plurality of units. In this embodiment, the volume (or volume) of trees is divided into multiple 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, Divide the total volume of multiple trees of the same species into multiple units, for example, each unit is 1 cubic meter, but is not limited to this, and each unit can also be more than 2 cubic meters. Each unit may be called a unit of volume or a unit of volume.

In one embodiment, when divided by the number of trees, there is one tree per unit, but it is not limited to this, and there can also be more than 2 trees per unit.

In one embodiment, when divided by the area of the planting area, each unit is the number of trees in a specific planting area, and the specific planting area can 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 is corresponding to the one divided in step S11. one or more units. The content information includes the owner information of the token, the number of units corresponding to the token (that is, the number of units held), and the information of the plants of the corresponding units. The content information may also include a total issued quantity of the plurality of units. Plant information can be, for example, the tree species, the market price of the trees in the unit corresponding to the token, and can also include tree age, planting area, planting quantity, carbon fixation amount, management team, management fees, etc. The content information may also include change information. The change information includes annual planting environment records, quantitative growth data (ie, plant growth data), increases and decreases in carbon fixation, current market prices, etc. When a pass is issued, the issuer can set the owner of the pass to himself or others.

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

In this embodiment, the issuer and owner of the token register in advance with the management node 20 to obtain an account and generate a private key and a public key corresponding to the account. The issuer's private key is held by the issuer, and the issuer The public key is sent to all nodes, the owner's private key is held by the owner, and the owner's public key 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 for registration.

The issuer logs in to the management platform 10 with its account from 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 then sends the issuance request to the Management platform10.

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 verification is correct, deploys the smart contract of the corresponding token and issues the corresponding token based on the content information.

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

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

Through the above steps, the issuance of plant certificates is completed, and physical plants are converted into digital assets.

The foregoing description takes 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 can optionally be performed.

The query step includes the following steps: a query device sets a pass query condition, and the query device sends a query request to the management node 20 according to the pass query condition; the management node 20 uses the smart contract according to the The pass query conditions are used to query, and the query results are sent 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 .

The query device takes the owner device 40 as an example. The token owner logs in to the management platform 10 with its account from the owner device 40 to set the token query conditions. The token query conditions can be any of the content information. or multiple pieces of 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 conditions. The management platform 10 receives the query request and transmits the query request to the management node 20 . The management node verifies the query request with the corresponding public key, and after verification is correct, queries according to the token query conditions through the smart contract, and transmits the query results to the owner device through the management platform 10 40. 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 match the owner information.

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

The query device takes the issuer device 30 as an example. The query steps are also the same. The difference is that the private key used for signature and the public key used for verification are different. Similarly, if the queried token is held by the issuer, the issuer device 30 can also interact with the smart contract corresponding to the token to manage the owned 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 transmitting the query request and query results through the management platform 10.

The update step includes the following steps: setting new content information of the at least one token by an update device, and sending an update request to the management node 20. The management node 20 uses the smart contract to The new content information of the at least one token is updated to the distributed ledger 101a of the multiple nodes 101.

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 .

The update device takes the issuer device 30 as an example. The issuer uses the issuer device 30 to log in to the management platform 10 with its account to set new content information of the token to be updated, so as to change any content information. One or more pieces of 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 new content information of the token to be updated. The management platform 10 receives the update request and transmits the update request to the management node 20 . The management node 20 verifies the update request with the corresponding public key, and after verification is correct, updates the new content information of the token to the multiple nodes 101 on the blockchain network 100 through a smart contract. Decentralized ledger 101a. Then the management node 20 transmits the updated result to the issuer device 30 through the management platform 10 .

The update device takes the owner device 40 as an example. The update steps are also the same. The difference is 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 transmitting 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 takes a wallet address on the blockchain network 100 as an example, but is not limited to this and can also be a cold wallet. The wallet of the issuer device 30 links the token owned by the issuer and its content information, and the wallet of the owner device 40 links the token owned by the owner and its content information. The issuer and owner can check the wallet on their respective issuer device 30 and owner device 40 to learn the tokens they own and their content information.

In addition to issuing certificates for plants, a carbon rights certification agency may also evaluate and certify the carbon rights of the plurality of plants in the at least one plant planting area, so as to convert the plurality of plants into Plants are converted into corresponding multiple carbon rights units (i.e., the first carbon rights unit). Then, a plurality of carbon right certificates (i.e., first carbon right certificates) are issued on the blockchain network 100, and the plurality of first carbon right certificates correspond to the plurality of first carbon right units, For example, the issuer device 30 sets a piece of content information of the first carbon right token through the management platform 10. The content information of each first carbon right token includes the number and owner of its carbon right unit. For example, the management node 20 issues a plurality of first carbon rights certificates through a carbon rights smart contract, and then adds the plurality of first carbon rights certificates and their content information to the blockchain network 100 The distributed ledger 101a of the multiple nodes 101. In addition, the plurality of first carbon right tokens are linked to the wallet of the issuer device 30 . The issuer can check the wallet on the issuer's device 30 to learn the first carbon rights token it owns and its content information. Therefore, in addition to obtaining plant tokens, you can also obtain plant-derived carbon rights.

Figure 3 shows a plant asset management system 2 according to the second preferred embodiment of the present invention. It has a structure that is substantially the same as that of the first embodiment. The difference is that the issuer device 30 and the owner device 40 are the blocks respectively. A node 101 on the blockchain network 100, therefore, does not need to be connected to the blockchain network 100 through the management platform 10.

The plant asset management method of this embodiment is roughly the same as that of the first embodiment. The difference is that in step S12, the issuer sets the content information of the token on the issuer device 30, and the issuer device 30 signs the certificate with a private key. After the Chapter 1 issuance request is made, the issuance request and the content information are sent to the management node 20 . The management node 20 verifies the issuance request with the corresponding public key, and after verification is correct, deploys the smart contract of the corresponding token and issues the corresponding token based on the content information.

Therefore, plant tokens 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, there is no need to issue carbon rights certificates through the management platform 10.

Figure 4 shows a plant asset management method according to the third preferred embodiment of the present invention. It is based on the first embodiment and after step S13, it also includes:

Step S14: After a period of time, obtain a growth increment of the plurality of 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, one year, or two. Year, after the plants grow, measure the total volume of the multiple trees in the plant planting area again to obtain the growth increment of the multiple plants compared to step S11, that is, the increase in the total volume. The greater the growth increment, the greater the number of units obtained by division. The division method is the same as step S11.

Step S15: Establish content information of at least one other token through the smart contract and issue the other token, wherein the other token is one or more units divided corresponding to the growth increment. ; The content information of the other pass includes owner information, the number of corresponding units of the other pass, and the information of the plants of the corresponding units. The content information of the other pass is the same as the content information of the pass of the first embodiment.

In this embodiment, the issuer uses the issuer device 30 to log in to the management platform 10 with its account to set the content information of the other token, and the issuer device 30 signs an issuance request with a private key. The issuance request is then sent 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 verification is correct, deploys the corresponding smart contract and issues the corresponding other token based on 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 the issuer device 30. After signing the issuance request with the private key, the issuance request and the content information are sent to the management node 20. The management node 20 verifies the issuance request with the corresponding public key, and after verification is correct, deploys the corresponding smart contract and issues the corresponding other token based on the content information. Therefore, 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 multiple 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 the growth of plants is completed, and the growth of physical plants is converted into digital assets.

In addition, in this embodiment, a carbon rights certification agency can also evaluate and certify the carbon rights of the multiple plants after they have grown in the at least one plant planting area, by comparing the carbon rights of the plants before they grow. The carbon rights and the carbon rights after growth can be used to obtain the carbon rights corresponding to the growth increment, and convert the growth increments of the multiple plants into corresponding multiple carbon right units (ie, second carbon right units). Then, a plurality of carbon right certificates corresponding to the growth increment (i.e., second carbon right certificates) are issued on the blockchain network 100. The plurality of second carbon right certificates are corresponding to the plurality of third carbon right certificates. The second carbon right unit, for example, the issuer device 30 sets a piece of content information of the second carbon right token through the management platform 10. The content information of each second carbon right token includes the number of its second carbon right unit, owner. The management node 20 then issues a plurality of second carbon rights certificates through a carbon rights smart contract, and then adds the plurality of second carbon rights certificates and their content information to the blockchain network 100 The distributed ledger of the multiple nodes 101. In addition, the plurality of second carbon right tokens are linked to the wallet of the issuer device 30 . The issuer can check the wallet on the issuer's device 30 to learn the carbon rights tokens (second carbon rights tokens and/or first carbon rights tokens) and the content information of the carbon rights tokens it owns.

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 foregoing, the at least one other token to be issued incrementally is taken as an example, and in practice it can be multiple tokens.

Figure 5 shows a plant asset management system 4 according to the fourth preferred embodiment of the present invention, which is based on the first embodiment. The management platform 10 is also connected to a plant market price public information platform 50. The plant market price public information The platform 50 may be provided, for example, by an authority that manages plants (such as the Forest Service) or a third-party notary agency.

The plant asset management method of this embodiment includes: the management platform 10 obtains the market prices of the plurality of plants from the plant market price public information platform 50 and calculates the divided units according to the market prices of the plurality of plants. The market price is recorded in the content information of the token. When the token is issued, the market price will record the content information. The issuer can regularly use the update step by the issuer device 30 to update the market price to the change information in the content information of the pass, or authorize a third party, and the authorized third party can regularly use the update step to update the market price to the content of the pass. Information about changes in information. Therefore, it is easier to understand the changes in the market price of the plants corresponding to the token.

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

The above are only preferred and feasible embodiments of the present invention. All equivalent changes made by applying the description and patent scope of the present invention should be included in the patent scope of the present invention.
