A peer-to-peer (P2P) network structure is used to connect, and they can be computer devices with network functions, such as personal computers, notebook computers and servers, etc. The blockchain network B can be Ethernet Ethereum (Etherum, ETH) or other similar blockchain networks.

The trading platform 1 is one of the several node hosts, and the trading platform 1 can be an online trading platform such as OpenSea, Lootex, OurSong, Binance or Nifty Gateway, but not limited thereto. The trading platform 1 is used for deploying a smart contract (Smart Contract) to the blockchain network B. The smart contract includes several ownership certificates corresponding to several physical assets, and the several physical assets are respectively in the real world. several trees, the trading platform 1 forms the several ownership certificates by tokenizing the several trees. In this embodiment, each of the ownership certificates belongs to a non-fungible token (Non-Fungible Token). , NFT), and the smart contract is compatible with the ERC-721 non-fungible token standard. Among them, the technology of tokenization of physical assets belongs to the common knowledge in the field of this creation, and will not be repeated here.

The leasing platform 2 is coupled to the trading platform 1, and has a creation module 21, a database module 22 and an allocation module 23, wherein the creation module 21 is used to create and send the smart contract to the transaction Platform 1, and used to apply for a first wallet. In this way, the leasing platform 2 can purchase virtual currencies such as ether through the first account, and store the purchased ether in the first wallet to perform transactions such as creating and purchasing the several ownership certificates, and The plurality of ownership certificates are stored, sent and received with the first wallet.

Specifically, the first wallet belongs to a Cryptocurrency Wallet, which records a public key used to represent a Wallet Address and a private key used to prove ownership. Furthermore, the public key and the key are both generated by hashing and encoding, for example, hashing may be performed by SHA-256 or RIPEMD-160, and encoding may be performed by Base56Check, but not limited thereto.

The creation module 21 can also set the issued quantity of each of the ownership certificates and decide to issue them on the blockchain network B. In this embodiment, the issued quantity of each of the ownership certificates is set to one. Preferably, the creation module 21 can also set the ownership certificate to have a serial number or no serial number, which can be understood by those with ordinary knowledge in the field of creation.

The database module 22 is used for storing a certificate list, and the certificate list is used to record the life cycle of the tree corresponding to each ownership certificate and its carbon dioxide absorption and profit sharing amount. In this embodiment, the life cycle of the tree is The cycle is divided into reproductive period, semi-adult period, adult period and old age period, and the corresponding carbon dioxide absorption amount and profit share amount can be shown in the following table for example:

Table: List of Credentials The life cycle carbon dioxide absorption Profit distribution amount certificate of use Certificate of Ownership 1 semi-adult 10kg/year 2500 yuan/year first wallet address Certificate of Ownership 2 adulthood 12kg/year 3000 yuan/year Second wallet address Certificate of Ownership 3 Breeding Season 6kg/year 1500 yuan/year first wallet address Certificate of Ownership 4 old age 8.5kg/year 2125 yuan/year Second wallet address Certificate of Ownership 5 adulthood 12kg/year 3000 yuan/year first wallet address

The distribution module 23 is electrically connected to the creation module 21 and the database module 22, and is used for obtaining a carbon dioxide emission amount according to a carbon footprint calculation, and then selects at least one carbon dioxide emission amount from the database module 22 according to the carbon dioxide emission amount A certificate of title, the sum of the carbon dioxide absorption of the at least one certificate of ownership is not less than the carbon dioxide emission, so as to generate a certificate combination. The distribution module 23 sends the certificate combination to the electronic device 3 for the user to which the electronic device 3 belongs to confirm at least one ownership certificate to be purchased.

The electronic device 3 is coupled to the rental platform 2. In this embodiment, the electronic device 3 is a computer device with network function, such as a personal computer, a smart phone, a notebook computer, and the like. The electronic device 3 has a second wallet, and sends the carbon footprint to the rental platform 2 to obtain and display the certificate combination. The electronic device 3 sends a transaction request to the rental platform 2, so that the rental platform 2 uses the smart contract to generate at least one usage right certificate relative to the at least one ownership certificate, and redeploys the smart contract through the trading platform 1 In the blockchain network B, and transferring the at least one usage right certificate to the second wallet, that is, the at least one usage right certificate is transferred from the rental platform 2 to the user.

Please refer to the above table, the ownership of the plurality of use right certificates corresponding to the plurality of ownership certificates, the default value is that they belong to the rental platform 2, and the plurality of use right certificates are initially stored in the first wallet, which means That is, in the certificate list, the usage right certificate of each ownership certificate is preset as the wallet address of the first wallet (eg, the first wallet address). Furthermore, the transaction request may include the certificate combination and the wallet address of the second wallet. After receiving the transaction request, the leasing platform 2 may combine the wallet address of the second wallet (eg, the second wallet address) with the wallet address of the second wallet. The corresponding at least one usage right certificate is recorded in the certificate list of the database module 22 .

On the other hand, the profit amount obtained by the operator of the leasing platform 2 by leasing the trees can be distributed according to the investment ratio of the user of the electronic device 3 . Specifically, the distribution module 23 obtains the distribution amount relative to the at least one usage right certificate, converts the distribution amount into an equivalent virtual currency, and sends it to the second wallet. Preferably, the distribution module 23 can set a profit sharing period (for example: 1 year), and only send virtual currency equivalent to the profit sharing amount to the second wallet on the settlement date of the profit sharing period.

It is worth noting that during the period of holding the at least one usage right certificate, the user can sell the at least one usage right certificate at any time to obtain greater benefits. For example, the user believes that the amount of profit obtained from the at least one use right certificate in the next few years is lower than the amount that can be obtained by selling the at least one use right certificate, so the user sells the at least one use right certificate to others. However, in the certificate list of the database module 22, if the wallet address corresponding to the at least one usage right certificate is not updated, the distribution amount relative to the at least one usage right certificate cannot be sent to the at least one usage right certificate. The wallet of the latest owner of at least one usage right certificate.

In order to solve the above problem, the at least one usage right certificate is sold to the user of another electronic device 3 through the trading platform 1, and after the transaction between the two users is completed, the user of the other electronic device 3 must pass The belonging electronic device 3 logs into the rental platform 2, and sends the wallet address of a third wallet belonging to the rental platform 2 to update the wallet address corresponding to the at least one usage right certificate, that is, the certificate The wallet address of the second wallet in the list is modified to the wallet address of the third wallet. Thereby, the distribution module 23 can surely send the distributed amount to the wallet of the user who currently has the at least one usage right certificate.

Furthermore, the allocation module 23 can also set a holding period (for example: 3 years) for each of the usage rights certificates, and send a subscription notice to the electronic device 3 on the expiry date of the holding period. The electronic device 3 returns an approval message to the rental platform 2, which means that the user of the electronic device 3 is willing to buy the tree held by the at least one usage right certificate, and the rental platform 2 sends a transaction message to the rental platform 2. The electronic device 3, the transaction message includes the first wallet and a purchase amount, so that the user can trade the virtual currency of the purchase amount to the first wallet through the electronic device 3. After the first wallet of the leasing platform 2 receives the virtual currency corresponding to the purchase amount, it sends the ownership certificate relative to the at least one usage right certificate to the second wallet through the trading platform 1 to complete the transaction. Thereby, the user can choose to keep the at least one usage right certificate, or sell the at least one usage right certificate to other people through the trading platform 1 to obtain greater benefits.

On the other hand, if the electronic device 3 returns a disapproval message to the rental platform 2, that is, the user is unwilling to buy the tree with the at least one use right certificate, the at least one use right certificate The certificate can be automatically transferred from the second wallet to the first wallet through the trading platform 1 on the expiry date of the holding period.

As mentioned above, the virtual currency-based transaction management system of this creation can cast several trees in the real world through the trading platform into the several ownership certificates, and use the leasing platform to communicate with those who need to implement carbon neutrality. The company conducts transactions to provide at least one certificate of use right corresponding to the relative number of trees that meet the carbon dioxide emissions generated by the company's carbon footprint, and the operator of the leasing platform obtains by leasing the number of trees. The profit amount can be distributed according to the investment ratio of the company. In this way, the virtual currency-based transaction management system of this creation can ensure that consumers who purchase certificates have the right to use and/or ownership of the trees corresponding to the certificates, and can obtain the corresponding profit sharing effect.
