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 further include a total issued quantity of the plurality of units. The 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 fixed amount, management team, management fees, etc. The content information may further 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.

The above-mentioned 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. In the future, the pass can be queried, updated, and even traded.

Figure 6 shows the 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 The 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 supply-side device 70 and a demand-side device 80 . In this embodiment, the plant asset trading system 5 can cooperate with the plant asset management system 1 of the first embodiment to form a plant asset management and trading system.

The trading platform 60 is used to provide the supplier (ie, the seller or owner) of the token. ) and the demand-side (buyer) token sales information and token historical transaction price information, or transaction matching information and token market price information. The trading platform 60 may be a node 101 in the blockchain network 100 , but is not limited thereto, 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 they 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, where the sales information 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 transaction platform 60. However, this is not a limitation. The supplier device 70 can also be connected to the blockchain network 100. It can be a node 101 in the blockchain network 100. When the issuer device 30 or the owner device 40 wants to sell tokens and connects to the trading platform 60 to set the sales information, the issuer device 30 or the owner device 40 becomes the The supplier device 70 is described. 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 transaction platform 60 to set a transaction request. The demand-side device 80 may be, for example, a mobile device, a computer, a workstation, a server, or a cloud host. In this embodiment, the demand-side device 80 is independent of the blockchain network 100 and can be connected to the blockchain network 100 through the transaction platform 60. However, this is not a limitation. The demand-side device 80 can also be connected to the blockchain network 100. It can 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 demander device 70 is defined as a second wallet.

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 supply side and the demand side from the management platform 10 .

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

The sales information is then published. The way of publishing the sales information may be, for example, that the supplier device 70 publishes the sales information on the trading platform 60 , or the trading platform 60 actively publishes the sales information after the management node 20 verifies that it is correct. sales information, or the supplier publishes the sales information on its own, such as on social networking sites or using communication software.

Step S25: Set a transaction request to conduct a transaction. In this embodiment, the demander logs in to the transaction platform 60 with the account of the demander device 80 and sets the transaction request and signs it with his private key, and then sends it to the management by the transaction platform 60 Node 20. The management node 20 verifies the transaction request with the corresponding public key, and notifies the transaction platform 60 to conduct the transaction after the verification is correct. 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 device 80 connects to the transaction platform 60 to query and publish the sales information. The trading platform 60 obtains the content information and sales information of the token from the management node 20 and sends them to the demander device 80 . The demand side examines the token being sold, its content information and the sales price to decide whether to purchase it.

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

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. The financial service host 90 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. account. The financial service host 90 generates transfer information after the financial transfer of the transaction is completed, and transmits the transfer information to the transaction platform 60 . After receiving the transfer information, the trading platform 60 sends a transaction completion message to the management node 20, indicating that the transaction has been completed. The transaction completion message may be a token transfer request.

Step S26: After the transaction is completed, generate a transaction information, the transaction information includes the transaction token, the transaction price, a supplier information and an owner information; and perform a token transfer step to transfer the transaction The token is transferred to the demander.

In this embodiment, after receiving the transaction completion message from the trading platform 60, the management node 20 generates the transaction information, and performs the token transfer step based on 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 multiple 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 distribution of the multiple nodes in the blockchain network 100 Formula Ledger 101a.

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

In the token transfer step, this embodiment also includes transferring one or more carbon rights tokens corresponding to the traded tokens from the first wallet of the supply-side device 70 to the second wallet of the demand-side device 80, thereby , the demander not only obtains the plant’s certificate, but also obtains a corresponding number of carbon rights certificates.

In addition, after the demander obtains the token, it can also become a supplier and then sell the token. By performing the above steps S24 to 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 carbon rights certificates, then in the above step S15, the financial service host 90 does not need to provide financial transfer services, and the transfer of carbon rights certificates can be directly used. to complete the transaction. More specifically, in step S15, the demander operates the demander device 80 to transfer at least part of the carbon right tokens in the second wallet to the first wallet, where the carbon right tokens transferred are related to the plant. The price of the token to be sold is equivalent to that of the token. After the carbon right token is transferred, the supplier device 70 or the supplier device 70 generates a transfer information and sends it to the trading platform 60, and the trading platform 60 sends a transaction completion message to the management node 20. .

Therefore, the demander can use the carbon rights certificate it owns as the currency of transaction to purchase plant certificates.

In the above-mentioned fifth preferred embodiment, the transaction between the supplier and the demander is in the form of off-take as an example. Hereinafter, a plant asset trading method according to the sixth preferred embodiment is provided, which is based on matchmaking. way to conduct transactions. The sixth preferred implementation of the present invention has substantially 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 number of units corresponding to the token to be sold, and the number of units to be sold. s price.

Step S25: The transaction request set by the demand-side device 80 on the trading platform 60 includes a purchase information. The purchase information includes the token to be purchased, the number of units to be purchased and the number of units to be purchased. s price. The trading platform 60 performs the transaction based on the sales information and the acquisition information. The trading platform 60 generates transaction matching information and market price information to conduct transactions, such as bidding transactions. After the transaction is completed, the transaction 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 carbon rights certificates, then in the above step S25, the financial service host 90 does not need to provide financial transfer services, and the transfer of carbon rights certificates can be directly used. to complete the transaction.

Figure 8 shows a plant asset trading system 7 according to the seventh preferred embodiment of the present invention. It has a structure that is substantially the same as that of the fifth embodiment. The difference is that the supply-side device 70 and the demand-side device 80 are respectively the blockchain. A node 101 on the network 100, therefore, does not need to be connected to the blockchain network 100 through a trading platform.

The steps of the plant asset trading method of this embodiment are roughly the same as those of the fifth embodiment, and the differences are:

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

The sales information is then published for viewing by the demand-side device 80 . The method of publishing the sales information may be, for example, the supply-side device 70 connecting to the trading platform 60 and publishing the sales information on the trading platform, or on the management node 20 After verification, the trading platform 60 will actively publish the sales information, or the supplier will publish the sales information on its own.

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

Afterwards, after receiving the transaction completion message from the trading platform, the management node 20 generates the transaction information, and performs the token transfer step based on the transaction information, thereby completing the token transaction.

Figure 9 shows a plant asset management system 8 applied to the plant asset management method of the eighth preferred embodiment of the present invention. It has a structure that is substantially the same as that of the first embodiment, and also includes an update device A0 connected to the management system 8. Platform 10, the update device A0 is connected to the management node 20 through the management platform 10 to set a growth data of the plurality of plants corresponding to each pass.

In this embodiment, the update device A0 is operated by a third-party notary agency. 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, measuring the total volume of trees is used as an example, but it is not limited to this. The update device A0 may be any node 101 on the blockchain network 100 or other devices. The third-party notary institution 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 for registration. . The update device A0 signs the request with the private key, and the management node 20 verifies the request with the public key, which are the same as in the previous embodiments and will not be described again.

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

Step S31: Provide at least one token in the blockchain network 100. 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 one pass is taken as an example, but it is not limited to this, and multiple passes can also be issued. The steps for issuing a token are the same as those in 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 pass through the smart contract, and adds the pass and its content information to the distributed ledger 101a of the multiple nodes in the blockchain network 100. In this embodiment, the change information of the content information records the growth data when the plurality of plants are divided into units. For example, a third-party notary agency provides the growth data to the issuer, and the issuer sets the initial growth data in the change information.

In addition, the issuer device 30 is also connected to the management node 20 and sets an update authority in the smart contract to the update device A0. The update authority allows the update device A0 to set the corresponding token. Growth data of the plurality of plants.

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

In this embodiment, the third-party notary agency measures the growth data of the plants every once in a while, such as one season, half a year, one year, or two years, such as measuring the current total volume of the plants, and the updating device A0 passes the data. The management platform 10 or directly connects to the management node 20 to set the growth data in the smart contract. More specifically, the third-party notary agency logs in to the management platform 10 with its account from the update device A0 to set up the growth data. Determine the growth data corresponding to the content information of the token, and send an update request and growth data to the management node 20. The management node 20 updates the growth data to the decentralized system of the multiple nodes 101 through the smart contract. The ledger 101a, 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 uses the issuer device 30 to connect to the management node 20 through the management platform 10 to query the growth data in the change information of the token, and based on the latest growth data and the previous growth data The growth increment is calculated based on the difference between the two, but is not limited to this. The smart contract can also automatically calculate the growth increment based on the difference between the latest growth data and the previous growth data. The greater the growth increment, the more units can be obtained by subsequent divisions.

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 at least a part of the growth increment. Divide one or more of said units. The content information of the other token includes the quantity of the corresponding unit of 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, and the issuer device 30 sets the content of the other token. information and transmit the issuance request and the content information to the management node 20 through the management platform 10, and issue another token through the smart contract.

Step S34: 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 101 in the blockchain network 100.

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

In this embodiment, in step S31, a carbon rights certification agency may also evaluate the multiple plants in the at least one plant planting area and certify the carbon rights of the multiple plants as in the first embodiment. , to convert the plurality of plants into corresponding plurality of carbon rights units (i.e., the first carbon rights units). 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 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. The plurality of first carbon rights tokens are linked to the wallet of the issuer device 30 .

After step S32, as in the third embodiment, a carbon rights certification agency may evaluate the multiple plants grown in the at least one plant planting area and certify the carbon rights of the multiple plants, by 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 increments of the multiple plants can be converted into corresponding multiple carbon right units (i.e., the second carbon right unit). Then, a plurality of carbon right certificates (ie, second carbon right certificates) are issued on the blockchain network 100, and the plurality of second carbon right certificates correspond to the plurality of second carbon right units. For example, the management node 20 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 101a of the multiple nodes 101. In step S34, the wallet included in the issuer device 30 links the plurality of second carbon rights tokens.

In practice, the issuer device 30 can also be the node 101 on the blockchain network 100, and can directly transmit the issuance request and the content information to the management node 20, thereby eliminating the need to go through the management platform 10 The other pass can be issued. The update device A0 can also be the node 101 on the blockchain network 100, and can directly transmit the update request and growth data to the management node 20.

Figure 11 shows the plant asset trading system 8a used in the plant asset trading method of this embodiment. It is based on the aforementioned plant asset management system 8, combined with a trading platform 60 similar to the fifth embodiment, and a supplier The difference between the device 70 and the demand-side device 80 is that the issuer device 30 in this embodiment becomes the supply-side device 70 to sell the other token issued corresponding to the growth increment.

The plant asset trading method of this embodiment includes the following steps shown in Figure 12, which is based on the plant asset management method of this embodiment and has the same steps S31 to S34, and also includes:

Step S35: Set a sales information, the sales information 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 perform a transaction.

In addition, this embodiment also 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 price of the transaction, a supplier information and an owner information. ;And perform a pass transfer step;

Among them, the token transfer steps include:

The transaction information is updated to the corresponding content information of the at least one other token, and updated to the distributed ledger 101a of the multiple nodes in the blockchain network.

The contents of the above-mentioned steps S35 to S37 are respectively the same as the steps S24 and S26 of the fifth embodiment. The only difference is that the sales target is the other token, so the steps can be used and will not be described again. In the token transfer step, the corresponding second carbon right token can also 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 matchmaking 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. There is no need to connect to the blockchain network 100 through a trading platform, and steps S35 to S36 can follow steps S24 and S25 in the seventh embodiment.

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

More specifically, step S33 includes updating a change information in the content information of the at least one token in the distributed ledger 101a of the multiple nodes 101 on the blockchain network 100. The change information Contains a quantity of incremental units corresponding to a portion of the growth increment. Establish the content information of the other pass on the blockchain network 100 and issue the other pass, wherein the other pass is one divided corresponding to the growth increment of another part or a plurality of said units.

In the foregoing, 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, and the number of the increment units corresponds to The growth increment of the first part, that is, the smart contract generates the increment of the change information based on the growth increment of the first part and the original number of units of the token. Units, the greater the number of original units of the said token, the more incremental units will be obtained. The management node 20 updates the number of incremental units of the change information of the original token to the distributed ledgers 101a of the multiple nodes 101 through the smart contract. Therefore, the total number of units of the original token is increased. The total unit is the number of token units plus the number of incremental units, so that the token can increase in value as the plant grows.

The other token issued incrementally is the unit divided corresponding to 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. And the issuer device 30 is connected to the management node 20 to create the content information of the at least one other pass in the smart contract and issue the at least one other pass.

Therefore, a part of the growth increment can be converted into incremental units of the original pass, and the issuer of the other part of the growth increment pass can then issue at least one other pass, and the at least one other pass can be subsequently transferred. The sale of certificates allows both the owners and issuers of the original certificates to make profits based on the growth of plants. And the owner and issuer can obtain carbon rights certificates corresponding to the growth increment in the wallets of their respective devices, representing the carbon rights of the plant.

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

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.
