[0002] With the rapid development of renewable energy generation technology, green certificates and carbon emission rights trading systems have been widely used as market instruments to encourage the use of green energy and limit carbon emissions. Green certificates, also known as green electricity certificates, are digital certificates issued by an independent third party under state leadership. They uniquely identify each megawatt-hour of renewable energy (excluding hydropower) generated and serve as a proof of renewable energy consumption. Carbon emission rights are legally granted to companies to emit a certain amount of carbon dioxide, including voluntary emission reductions and carbon emission quotas certified by China.

[0003] Since the transactions of green certificates and carbon emission rights involve many trading parties, such as renewable energy management centers, supervisory agencies, and numerous sellers and buyers, and the amount involved in the transactions of green certificates and carbon emission rights is relatively large, the security requirements for the transaction process and transaction data of green certificates and carbon emission rights are very high.

[0029] Example 1

[0030] Figure 1 This is a flowchart of a transaction processing method provided by the first embodiment of the present invention. This embodiment is applicable to improving the security of the transaction process and transaction data in green certificates and carbon emission rights transactions. The method can be executed by a transaction processing platform, which can be a platform built on the blockchain and implemented by software and / or hardware. It can generally be directly integrated into the electronic device that executes this method. The electronic device can be a terminal device or a server device. The embodiment of the present invention does not limit the type of electronic device that executes the transaction processing method. Specifically, Figure 1 As shown, the transaction processing method may specifically include the following steps:

[0031] S110: Obtain first user information of a first user, and determine green certificate information or carbon emission rights information of the first user based on the first user information.

[0032] The first user may be the seller in a transaction involving green certificates and carbon emission rights. For example, the first user may be a renewable energy power generation unit or a fossil energy power generation unit, etc., though this is not a limitation in the present embodiment. It is understood that the first user may be the seller of green certificates or the seller of carbon emission rights. Furthermore, there may be one or more first users, and the multiple first users may include both green certificate sellers and carbon emission rights sellers.

[0033] Among them, the first user information can be the information of the selling user in the green certificate and carbon emission rights transaction.

[0034] Specifically, the first user information may include the user information provided by the first user when registering on the transaction processing platform. For example, the first user information may include power generation data of renewable energy power generation units and fossil energy power generation units, carbon emissions data of fossil energy power generation units, etc., although this embodiment of the present application is not limited thereto.

[0035] Specifically, the first user information may also include the first user's asset information in the transaction processing platform. For example, the first user information may include green certificate balance data, carbon emission rights balance data, currency balance data, account address information, etc., which is not limited in this embodiment of the present application.

[0036] Among them, the green certificate information can be information related to the green certificate, for example, it can include green certificate identifier information, green certificate timestamp information, green certificate file data or green certificate quota data, etc., and the embodiments of the present application do not limit this.

[0037] Among them, carbon emission rights information can be information related to carbon emission rights, for example, it can include carbon emission rights identifier information, carbon emission rights timestamp information, carbon emission rights file data or carbon emission rights quota data, etc., and the embodiments of the present application do not limit this.

[0038] In this embodiment of the present invention, the transaction processing platform may obtain the first user's first user information to determine the first user's green certificate information or carbon emission rights information based on the first user information. It is understood that before the transaction processing platform obtains the first user's first user information, the first user may fill in registration information on the transaction processing platform and complete registration.

[0039] S120. Generate a green certificate token or carbon emission rights token corresponding to the first user based on the green certificate information or carbon emission rights information of the first user.

[0040] Among them, a green certificate token can be a token that can identify a green certificate. A carbon emission rights token can be a token that can identify carbon emission rights. Specifically, the token can be a non-fungible token (NFT). A non-fungible token is an encrypted digital asset based on blockchain technology. It is indivisible, non-fungible, and unique. Each NFT token represents ownership of a specific digital or physical asset and has a unique identity and metadata.

[0041] It is understandable that different users have different green certificate tokens corresponding to them, and different users also have different carbon emission rights tokens corresponding to them.

[0042] In an embodiment of the present invention, after determining the first user's green certificate information based on the first user's information, the transaction processing platform may generate a green certificate token corresponding to the first user based on the first user's green certificate information. Alternatively, after determining the first user's carbon emission rights information based on the first user's information, the transaction processing platform may generate a carbon emission rights token corresponding to the first user based on the first user's carbon emission rights information.

[0043] S130. Based on the green certificate token or carbon emission rights token, a green certificate transaction or a carbon emission rights transaction is conducted between the first user and the second user.

[0044] The second user can be the purchaser of a green certificate and carbon emission rights transaction. For example, the second user can be a government agency, an enterprise, a high-energy-consuming enterprise, an energy company such as the State Grid Corporation of China, etc., but this embodiment of the application does not limit this. It is understood that the second user can be the purchaser of a green certificate or the purchaser of carbon emission rights.

[0045] Green Certificate trading involves trading green certificates. Specifically, one green certificate is equivalent to 1,000 kWh of renewable energy electricity, meaning one green certificate is obtained for every 1,000 kWh of renewable energy electricity produced. Carbon emission rights trading involves trading carbon emission rights. Specifically, one carbon emission right is equivalent to the right to emit one ton of carbon dioxide equivalent greenhouse gases.

[0046] In an embodiment of the present invention, after the transaction processing platform generates a green certificate token or carbon emission rights token corresponding to the first user based on the green certificate information or carbon emission rights information of the first user, it can conduct green certificate transactions or carbon emission rights transactions between the first user and the second user based on the green certificate token or carbon emission rights token.

[0047] The technical solution of this embodiment obtains the first user information of the first user, and determines the green certificate information or carbon emission rights information of the first user based on the first user information, so as to generate a green certificate token or carbon emission rights token corresponding to the first user based on the green certificate information or carbon emission rights information of the first user, thereby conducting green certificate transactions or carbon emission rights transactions between the first user and the second user based on the green certificate token or carbon emission rights token, which solves the problem that the transaction process and transaction data in the existing green certificate and carbon emission rights transactions are relatively poor in security, resulting in the inability to meet the transaction security requirements of green certificates and carbon emission rights, and can improve the security of the transaction process and transaction data in the green certificate and carbon emission rights transactions, thereby meeting the transaction security requirements of green certificates and carbon emission rights.

[0048] Example 2

[0049] Figure 2 This is a flow chart of a transaction processing method provided by the second embodiment of the present invention. This embodiment further refines the above technical solutions and provides a variety of specific optional implementation methods. The technical solution in this embodiment can be combined with the various optional solutions in one or more of the above embodiments. Figure 2 As shown, the method may include the following steps:

[0050] S210: Obtain first user information of a first user, and determine green certificate information or carbon emission rights information of the first user based on the first user information.

[0051] Optionally, green certificate information may include green certificate quota data. Carbon emission rights information may include carbon emission rights quota data. Green certificate quotas, also known as the Renewable Portfolio System (RPS), refer to requirements imposed on entities responsible for quotas (i.e., primary users), requiring them to produce renewable energy green electricity or purchase green certificates.

[0052] Optionally, determining the green certificate information or carbon emission rights information of the first user based on the first user information may include: determining the current quota period; determining the green certificate quota data or carbon emission rights quota data of the first user in the current quota period based on the first user information.

[0053] Among them, the quota period can be the usage period corresponding to the quota of the green certificate or carbon emission right. It is understandable that the quota of the green certificate or carbon emission right is valid within the quota period, and the quota of the green certificate or carbon emission right is invalid after the quota period. For example, the quota period can be one year or two years, etc., which is not limited in this embodiment of the present application. The current quota period can be the quota period corresponding to the green certificate or carbon emission right currently being traded.

[0054] Specifically, after obtaining the first user information of the first user, the transaction processing platform can further determine the current quota period, and determine the green certificate quota data or carbon emission quota data of the first user in the current quota period based on the first user information.

[0055] Optionally, before determining the green certificate quota data of the first user in the current quota period, it is also possible to determine whether the calculated green certificate quota data meets the quota constraint conditions; if the green certificate quota data meets the quota constraint conditions, the calculated green certificate quota data can be determined as the green certificate quota data of the first user in the current quota period.

[0056] Specifically, the quota constraint condition can be determined based on the following formula:

[0057]

[0058] in, Indicates the green electricity production of all renewable energy power generation units in the current quota period; Indicates the electricity generation of all units in the current quota period; represents the green electricity production of the i-th renewable energy generation unit in the current quota period; represents the power generation of the jth fossil energy power generation unit in the current quota period; m represents the number of renewable energy power generation units; n represents the number of fossil energy power generation units.

[0059] Optionally, determining the green certificate quota data of the first user in the current quota period based on the first user information may include: when the first user is a renewable energy power generation unit, determining the green certificate quota data of the first user in the current quota period based on the green electricity production of the first user in the current quota period and the output standard parameters of the first user.

[0060] Specifically, according to the green electricity production of the first user in the current quota period and the output standard parameters of the first user, the green certificate quota data of the first user in the current quota period is determined based on the following formula:

[0061]

[0062] in, represents the green certificate quota data of the i-th renewable energy power generation unit in the current quota period; α represents the output standard parameter of the i-th renewable energy power generation unit in the current quota period; wherein, the output standard parameter is related to the historical power generation data and the predicted values ​​of photovoltaic power generation and wind power generation.

[0063] Optionally, determining the green certificate quota data of the first user in the current quota period based on the first user information may include: when the first user is a fossil energy power generation unit, obtaining the green certificate quota completion information of the first user in the previous quota period from the first user information; when the green certificate quota completion information of the first user's previous quota period is an uncompleted green certificate quota, calculating the green certificate quota data of the first user in the current quota period based on the green certificate quota completion data of the previous quota period, the proportion of green electricity production in the current quota period to power generation, the first power generation data and the installed capacity data; when the green certificate quota completion information of the first user's previous quota period is a completed green certificate quota, calculating the green certificate quota data of the first user in the current quota period based on the proportion of green electricity production in the current quota period to power generation, the first power generation data and the installed capacity data.

[0064] Among them, the green certificate quota completion information may be information on whether the green certificate quota is completed within the quota period.

[0065] Specifically, when the green certificate quota completion information of the first user in the previous quota period is an uncompleted green certificate quota, the green certificate quota data of the first user in the current quota period can be calculated based on the following formula:

[0066]

[0067] Among them, Q l,j represents the installed capacity of the jth fossil energy power generation unit in the previous quota period; j represents the proportion of green certificate quota completed by the jth fossil energy power generation unit in the previous quota cycle; where λ j The larger the value, the higher the unfulfilled quota of the fossil energy power generation unit; θ g Indicates the adjustment parameter of green certificate quota.

[0068] Specifically, when the green certificate quota completion information of the first user in the previous quota period is the completion of the green certificate quota, the green certificate quota data of the first user in the current quota period can be calculated based on the following formula:

[0069]

[0070] Specifically, B can be installed capacity data; R can be the proportion of green electricity production to power generation in the current quota period; C can be the green certificate quota completion data of the first user in the previous quota period; It may be the first power generation amount data.

[0071] Optionally, determining the carbon emission quota data of the first user in the current quota period based on the first user information may include: when the first user is a fossil energy power generation unit, obtaining the carbon emission quota excess information of the first user in the previous quota period from the first user information; when the carbon emission quota excess information of the first user in the previous quota period is that the carbon emission quota is not exceeded, calculating the carbon emission quota data of the first user in the current quota period based on the first power generation data and the installed capacity data; when the carbon emission quota excess information of the first user in the previous quota period is that the carbon emission quota is exceeded, calculating the carbon emission quota data of the first user in the current quota period based on the carbon emission quota excess data of the previous quota period, the second power generation data and the installed capacity data.

[0072] The carbon emission rights quota excess information may be information on whether the carbon emission rights quota is exceeded within the quota period.

[0073] Specifically, when the carbon emission quota excess information of the first user in the previous quota period is that the carbon emission quota has not been exceeded, the carbon emission quota data of the first user in the current quota period can be calculated based on the following formula:

[0074]

[0075] in, represents the carbon emission quota data of the jth fossil energy power generation unit in the current quota period; d represents the conversion coefficient between the power generation and carbon emissions of the fossil energy power generation unit.

[0076] Specifically, when the carbon emission quota excess information of the first user in the previous quota period is exceeding the carbon emission quota, the carbon emission quota data of the first user in the current quota period can be calculated based on the following formula:

[0077]

[0078] Among them, μ jrepresents the proportion of carbon emission quota completed by the jth fossil energy power generation unit in the previous quota cycle; θ c represents the adjustment parameter of carbon emission quota, θ c It is related to the actual carbon emissions of fossil energy power generation units; Indicates the power generation of all fossil energy power generation units in the current quota period.

[0079] Specifically, D can be the carbon emission quota excess data of the previous quota cycle; It may be the second power generation amount data.

[0080] It is understood that, in the transaction processing platform, after determining the first user's green certificate quota data or carbon emission rights quota data in the current quota cycle, the renewable energy management center can distribute the quota to the first user through the transaction processing platform. The renewable energy management center is the institution that manages renewable energy-related affairs.

[0081] S221. Determine the green certificate identifier, green certificate timestamp, and green certificate file data corresponding to the first user based on the green certificate information of the first user.

[0082] The green certificate identifier may be information that uniquely identifies the green certificate. The green certificate timestamp may be information about the time at which the green certificate can be used. The green certificate file data may be data within the green certificate file. For example, the green certificate file data may include the certificate number, issuance date, validity period, company name, organization code, address, project name, project number, installed capacity, grid connection time, etc., which are not limited in the embodiments of the present application.

[0083] Specifically, the transaction processing platform can directly obtain the green certificate identifier, green certificate timestamp, and green certificate file data from the green certificate information. It is understood that after determining the green certificate quota data of the first user in the current quota period, the transaction processing platform can determine the green certificate information corresponding to the first user based on the green certificate quota data.

[0084] S222. Calculate the green certificate hash digest corresponding to the first user based on the green certificate identifier, the green certificate timestamp, and the green certificate file data.

[0085] The green certificate hash summary may be a hash summary corresponding to the green certificate file.

[0086] Optionally, before calculating the green certificate hash summary corresponding to the first user based on the green certificate identifier, the green certificate timestamp and the green certificate file data, it may also include: determining a target hash function; wherein the target hash function is a collision-resistant hash function.

[0087] The target hash function may be a hash function used to calculate the hash summary of the green certificate. For example, the target hash function may be H:{0,1} * →Z p Among them, Z p It can be a finite field, and p can be the prime order of the finite field.

[0088] Optionally, calculating the green certificate hash summary corresponding to the first user based on the green certificate identifier, green certificate timestamp and green certificate file data may include: calculating the green certificate hash summary corresponding to the first user based on the green certificate identifier, green certificate timestamp and green certificate file data based on the target hash function.

[0089] Specifically, the green certificate hash digest corresponding to the first user can be calculated based on the following formula:

[0090] h gc =H(ID gc ||T gc ||Data gc )

[0091] Among them, h gc Indicates the green certificate hash summary; ID gc Indicates the green certificate identifier; T gc Indicates the green certificate timestamp; Data gc Indicates green certificate file data.

[0092] S223. Determine the green certificate digital signature corresponding to the first user.

[0093] Among them, the green certificate digital signature can be the digital signature corresponding to the green certificate document.

[0095] The target finite field may be a finite field corresponding to the target hash function. For example, the target hash function H: {0, 1} * →Z p Z in p Can be a target finite field.

[0096] Specifically, the target elliptic curve can be a non-singular elliptic curve. For example, the target elliptic curve can be expressed as: 2 =x 3 +ax+b; where a and b are numbers in the target finite field and satisfy 4a 2 +27b 3 ≠0.

[0097] The target base point may be a point on the target elliptic curve, and the sampled data may be data obtained by random sampling in the target finite field.

[0098] Specifically, the target coordinate point can be determined based on the formula (x, y) = k·G, where (x, y) is the target coordinate point; k is the sampling data; and G is the target base point.

[0099] Specifically, the number of elements of the target finite field can be the target finite field Z p The target value can be determined based on the formula r = x mod p; where r is the target value; x is the horizontal coordinate data of the target coordinate point; p is the target finite field Z p prime order of .

[0100] The target public key information may be the public key published on the transaction processing platform.

[0101] Specifically, the target private key information can be determined based on the formula pk=sk·G; wherein pk is the target public key information, sk is the target private key information, and G is the target base point.

[0102] Specifically, according to the sampled data, the green certificate hash summary, the target value, the target private key information, and the number of elements, the green certificate digital signature corresponding to the first user is determined based on the following formula:

[0103]

[0104] Among them, Sig gc Digital signature for green certificate.

[0105] S224. Determine the first target file according to the green certificate file data, the green certificate identifier, the green certificate timestamp, the user address information of the first user, the green certificate hash summary, and the green certificate digital signature.

[0106] The first target file may be a file for generating a green certificate token. Specifically, the first target file may be a Json file.

[0107] Specifically, the transaction processing platform can combine the green certificate file data, green certificate identifier, green certificate timestamp, user address information of the first user, green certificate hash summary and green certificate digital signature into a Json file, which is also the first target file.

[0108] S225. Generate a green certificate token corresponding to the first user based on the first target file and the user address information of the first user.

[0109] It is understandable that the number of Green Certificate Tokens corresponding to the first user is the same as the number of Green Certificate quotas corresponding to the first user. That is, assuming that the first user's Green Certificate quota is 5, the number of Green Certificate Tokens of the first user is also 5.

[0110] Optionally, generating a green certificate token corresponding to the first user based on the first target file and the user address information of the first user may include: storing the first target file in an IPFS (InterPlanetary File System) server, and determining the hash address of the first target file stored in the IPFS server; determining the green certificate token metadata identifier corresponding to the first user based on the hash address of the first target file stored in the IPFS server; and generating a green certificate token corresponding to the first user based on the green certificate token identifier and the user address information.

[0111] Among them, the hash address of the first target file stored in the IPFS server can be used to verify whether the data in the IPFS has been tampered with.

[0112] Specifically, determining the green certificate token metadata identifier corresponding to the first user based on the hash address of the first target file stored in the IPFS server may include determining the hash address of the first target file stored in the IPFS server as the green certificate token metadata identifier corresponding to the first user.

[0113] Optionally, the transaction processing method provided in this embodiment may further include: determining a smart contract; wherein the smart contract may include: a green certificate trading smart contract based on a green certificate token; specifically, the green certificate trading smart contract may include a token generation function.

[0114] Specifically, the transaction processing platform can generate a green certificate token corresponding to the first user based on the green certificate token metadata identifier and user address information based on the token generation function in the green certificate transaction smart contract.

[0115] S231. Determine the carbon emission rights identifier, carbon emission rights timestamp, and carbon emission rights file data corresponding to the first user based on the carbon emission rights information of the first user.

[0116] The carbon emission rights identifier may be information that uniquely identifies a carbon emission right. The carbon emission rights timestamp may be information about the time at which the carbon emission rights can be used. The carbon emission rights file data may be data within the carbon emission rights file. For example, the carbon emission rights file data may include the quota number, issuance time, validity period, company name, organization code, industry classification, etc., although this is not limited in the present embodiment.

[0117] Specifically, the transaction processing platform can directly obtain the carbon emission rights identifier, carbon emission rights timestamp, and carbon emission rights file data from the carbon emission rights information. It is understood that after determining the first user's carbon emission rights quota data for the current quota period, the transaction processing platform can determine the carbon emission rights information corresponding to the first user based on the carbon emission rights quota data.

[0118] S232. Calculate the carbon emission right hash summary corresponding to the first user based on the carbon emission right identifier, the carbon emission right timestamp, and the carbon emission right file data.

[0119] The carbon emission rights hash summary may be a hash summary corresponding to the carbon emission rights file.

[0121] Specifically, the target hash function is the same as the target hash function determined in step S222 before calculating the green certificate hash summary corresponding to the first user based on the green certificate identifier, green certificate timestamp and green certificate file data, and is not repeated here.

[0122] Optionally, calculating the hash summary of the carbon emission rights corresponding to the first user based on the carbon emission rights identifier, the carbon emission rights timestamp and the carbon emission rights file data may include: calculating the hash summary of the carbon emission rights corresponding to the first user based on the carbon emission rights identifier, the carbon emission rights timestamp and the carbon emission rights file data based on the target hash function.

[0123] Specifically, the carbon emission rights hash summary corresponding to the first user can be calculated based on the following formula:

[0124] h ce =H(ID ce ||T ce ||Data ce )

[0125] Among them, h ce Represents the hash summary of carbon emission rights; ID ce Represents the carbon emission rights identifier; T ceIndicates the carbon emission rights timestamp; Data ce Represents carbon emission rights file data.

[0126] S233: Determine the digital signature of the carbon emission rights corresponding to the first user.

[0127] Among them, the carbon emission rights digital signature can be the digital signature corresponding to the carbon emission rights document.

[0128] Specifically, determining the digital signature of the carbon emission rights corresponding to the first user may include: determining the target finite field, and determining the target elliptic curve in the target finite field; determining the target base point in the target elliptic curve, and determining the sampling data in the target finite field; determining the target coordinate point based on the target base point and the sampling data; wherein the target coordinate point is a coordinate point in the target elliptic curve; determining the number of elements in the target finite field, and determining the target value based on the number of elements and the target coordinate point; determining the target public key information, and determining the target private key information based on the target public key information and the target base point; determining the digital signature of the carbon emission rights corresponding to the first user based on the sampling data, the carbon emission rights hash summary, the target value, the target private key information, and the number of elements.

[0129] Specifically, the carbon emission rights digital signature corresponding to the first user is determined based on the sampled data, the carbon emission rights hash summary, the target value, the target private key information, and the number of elements. This can be determined based on the following formula:

[0130]

[0131] Among them, Sig ce Digitally sign carbon emission rights.

[0132] S234. Determine the second target file according to the carbon emission rights file data, the carbon emission rights identifier, the carbon emission rights timestamp, the user address information of the first user, the carbon emission rights hash summary, and the carbon emission rights digital signature.

[0133] The second target file may be a file for generating carbon emission rights tokens. Specifically, the second target file may be a Json file.

[0134] Specifically, the transaction processing platform can combine the carbon emission rights file data, the carbon emission rights identifier, the carbon emission rights timestamp, the user address information of the first user, the carbon emission rights hash summary and the carbon emission rights digital signature into a Json file, which is also the second target file.

[0135] S235. Generate a carbon emission rights token corresponding to the first user based on the second target file and the user address information of the first user.

[0136] It is understandable that the number of carbon emission rights tokens corresponding to the first user is the same as the number of carbon emission rights quotas corresponding to the first user. That is, assuming that the carbon emission rights quota of the first user is 3, the number of carbon emission rights tokens of the first user is also 3.

[0137] Optionally, generating a carbon emission rights token corresponding to the first user based on the second target file and the user address information of the first user may include: storing the second target file in the IPFS server, and determining the hash address of the second target file stored in the IPFS server; determining the carbon emission rights token metadata identifier corresponding to the first user based on the hash address of the second target file stored in the IPFS server; and generating a carbon emission rights token corresponding to the first user based on the carbon emission rights token identifier and the user address information.

[0138] Among them, the hash address of the second target file stored in the IPFS server can be used to verify whether the data in the IPFS has been tampered with.

[0139] Specifically, determining the carbon emission rights token metadata identifier corresponding to the first user based on the hash address of the second target file stored in the IPFS server may include determining the hash address of the second target file stored in the IPFS server as the carbon emission rights token metadata identifier corresponding to the first user.

[0140] Optionally, the transaction processing method provided in this embodiment may further include: determining a smart contract; wherein the smart contract may include: a carbon emission rights trading smart contract based on a carbon emission rights token; specifically, the carbon emission rights trading smart contract may include a token generation function.

[0141] Exemplarily, the token generation function may be awardItem(player, tokenURI), where player may be user address information, and tokenURI may be a green certificate token metadata identifier or a carbon emission rights token metadata identifier.

[0142] Specifically, the transaction processing platform can generate a carbon emission rights token corresponding to the first user based on the carbon emission rights token metadata identifier and user address information based on the token generation function in the carbon emission rights trading smart contract.

[0143] It should be noted that the embodiment of the present invention does not limit the order of steps S221 - S225 and steps S231 - S235 , that is, steps S221 - S225 and steps S231 - S235 can be performed simultaneously.

[0144] S240. Based on the green certificate token or carbon emission rights token, a green certificate transaction or a carbon emission rights transaction is conducted between the first user and the second user.

[0145] Optionally, the transaction processing method provided in this embodiment may further include: determining a smart contract; wherein the smart contract may include: a green certificate trading smart contract based on a green certificate token and a carbon emission rights trading smart contract based on a carbon emission rights token; wherein the green certificate trading smart contract or the carbon emission rights trading smart contract may at least include: a quotation function, a queue sorting function and a transaction transfer function.

[0146] Specifically, the bidding function can include a bidding function for a seller user and a bidding function for a buyer user. For example, the bidding function for a seller user can be openConSaler(salerPrice, tokenID); where salerPrice can be the seller's bid, and tokenID can be the seller's green certificate token or carbon emission rights token. The bidding function for a buyer user can be openConBuyer(buyerPrice, buyerNum); where buyerPrice can be the buyer's bid, and buyerNum can be the buyer's purchase quantity.

[0147] Specifically, the queue sorting function may include a queue sorting function for seller users and a queue sorting function for buyer users. Exemplarily, the queue sorting functions may be sortConSalers() and sortConBuyers(). Specifically, the queue sorting function may sort the queues of seller users or buyer users based on the bids in the bid function.

[0148] Specifically, the transaction transfer function can be used to transfer green certificate tokens or carbon emission rights tokens, as well as transfer transaction currency. Exemplarily, the transaction transfer function can be conTrans().

[0149] Optionally, a green certificate transaction or a carbon emission rights transaction between a first user and a second user based on a green certificate token or a carbon emission rights token may include: determining the first transaction token of the first user and the first transaction price corresponding to the first transaction token based on the quotation function in the smart contract; wherein the first transaction token is the green certificate token or carbon emission rights token to be traded by the first user; performing a first verification on the first transaction token according to the transaction request of the second user; if the first verification is passed, transferring the first transaction token to the second user based on the transaction transfer function in the smart contract, and transferring the first transaction amount of the second user to the first user; wherein the first transaction amount is determined by the first transaction price.

[0150] The first transaction price may be the price at which the seller sells the Green Certificate Token or Carbon Emission Rights Token. The first transaction amount may be the amount the buyer purchases the Green Certificate Token or Carbon Emission Rights Token, which is the product of the number of tokens purchased and the price of a single token. For example, assuming the seller sells 5 units of Green Certificate Tokens and the price of each unit of Green Certificate Token (i.e., the first transaction price) is a, then when the buyer purchases 4 units of Green Certificate Tokens, the first transaction amount may be 4a.

[0151] It is understandable that before transferring the first transaction token to the second user, the smart contract address of the second user may be determined so as to transfer the first transaction token to the smart contract address of the second user.

[0152] Among them, the first verification may include token legitimacy verification and time validity verification.

[0153] Specifically, token legitimacy verification can be used to verify the legitimacy of the digital signature of the green certificate or the carbon emission right. Time validity verification can be used to verify the validity of the usage time of the green certificate quota or the carbon emission right quota.

[0154] Specifically, the legitimacy of the green certificate digital signature can be verified based on the following formula:

[0155]

[0156] If the formula r=x ' If modp is established, it can be determined that the green certificate digital signature is legal; otherwise, if the formula r = x ' If modp is not true, it can be determined that the green certificate digital signature is illegal.

[0157] Specifically, the legitimacy of the digital signature of carbon emission rights can be verified based on the following formula:

[0158]

[0159] If the formula r=x ' If modp is established, it can be determined that the digital signature of carbon emission rights is legal; otherwise, if the formula r = x ' If MODP does not hold, it can be determined that the digital signature of carbon emission rights is illegal.

[0160] Optional, such as Figure 3As shown, based on the green certificate token or carbon emission rights token, a green certificate transaction or carbon emission rights transaction between a first user and a second user may include: determining the second transaction token of the first user and the second transaction price corresponding to the second transaction token based on the quotation function in the smart contract; wherein the second transaction token is the green certificate token or carbon emission rights token to be traded by the first user; determining the third transaction token of the second user and the third transaction price corresponding to the third transaction token based on the quotation function in the smart contract; wherein the third transaction token is the green certificate token or carbon emission rights token to be purchased by the second user; when the number of first users and / or second users is multiple, based on the queue sorting function in the smart contract, queue sorting is performed for each first user and / or each second user; according to the queue sorting result, each first user and each second user is matched and cleared in turn; based on the transaction transfer function in the smart contract, transaction transfer is performed according to the matching and clearing result, so as to realize the green certificate transaction or carbon emission rights transaction between the first user and the second user.

[0161] The second transaction price may be the price set by the seller for selling green certificate tokens or carbon emission rights tokens. The third transaction price may be the price set by the buyer for purchasing green certificate tokens or carbon emission rights tokens.

[0162] Specifically, based on the queue sorting function in the smart contract, the first users and / or the second users are queued. It can be based on the queue sorting function in the smart contract, arranging the first users in the queue in ascending order of their prices, and arranging the second users in the queue in descending order of their prices.

[0163] For example, assume that the first users include user 11, user 12, user 13, user 14, user 15, and user 16; among them, user 11 sells 4 green certificates, each quoted at 10,000; user 12 sells 5 green certificates, each quoted at 13,000; user 13 sells 4 green certificates, each quoted at 12,000; user 14 sells 4 carbon emission rights, each quoted at 5,200; user 15 sells 5 carbon emission rights, each quoted at 4,000; user 16 sells 7 carbon emission rights, each quoted at 44 00; assume that the second users include user 21, user 22, user 23, user 24, user 25, and user 26; among them, user 21 purchases 4 green certificates, each quoted at 15,000; user 22 purchases 5 green certificates, each quoted at 17,000; user 23 purchases 3 green certificates, each quoted at 16,000; user 24 purchases 6 carbon emission rights, each quoted at 8,000; user 25 purchases 5 carbon emission rights, each quoted at 7,200; user 26 purchases 7 carbon emission rights, each quoted at 6,600.

[0164] Table 1 Queue sorting results

[0165]

[0166] Based on the queue sorting function in the smart contract, the queues of the first users and / or the second users are sorted, and the queue sorting results shown in Table 1 can be obtained.

[0167] Specifically, based on the queue sorting results, each first user and each second user is matched and cleared sequentially. This can be done by matching the first user and the second user in the order of their queues until the first user queue and the second user queue are empty. The actual transaction amount is the average of the first user's bid and the second user's bid.

[0168] For example, as shown in Table 1, during the green certificate transaction process, user 11 and user 22 are matched. User 11's 4 green certificates are sold to user 22. The actual transaction amount of a single green certificate is (10,000 + 170,000) / 2 = 13,500. User 22 purchases 4 green certificates and still needs 1 green certificate. Then, user 13's 1 green certificate is sold to user 22. The actual transaction amount of a single green certificate is (12,000 + 170,000) / 2 = 14,500. At this point, user 22's green certificate transaction is completed, and user 23's green certificate transaction continues. User 23 purchases 3 green certificates, and user 13 sells 4-1 green certificates. The actual transaction amount of a single green certificate is (12,000 + 160,000) / 2 = 14,000. This process continues until the number of users in the transaction list is empty.

[0169] It is understandable that the trading process of carbon emission rights is the same as that of green certificate trading, so I will not go into details here.

[0170] Optionally, transaction transfers can be performed based on the matching and clearing results, which may include transferring green certificate tokens or carbon emission rights tokens to the purchasing user, transferring the actual transaction amount to the selling user, and returning the remaining amount of the purchasing user to the purchasing user.

[0171] Specifically, after determining the second user's third transaction token and the third transaction price corresponding to the third transaction token, the transaction processing platform may transfer the bid amount to the smart contract. The bid amount is the product of the number of transaction tokens and the third transaction price. It should be noted that after the transaction is completed, the smart contract may refund the remaining amount to the second user. The remaining amount is the difference between the bid amount and the actual transaction amount.

[0172] Optionally, after a green certificate transaction or a carbon emission rights transaction is conducted between a first user and a second user based on a green certificate token or a carbon emission rights token, it may also include: performing a second verification on the green certificate token or the carbon emission rights token; wherein the second verification includes: verifying whether the number of tokens of the green certificate token or the carbon emission rights token meets the quota quantity conditions, verifying the time validity of the green certificate token or the carbon emission rights token, and verifying the legitimacy of the digital signature of the green certificate token or the carbon emission rights token.

[0173] The quota quantity condition may be whether the available quota quantity is consistent with the issued quota quantity within the current quota period.

[0174] It should be noted that the time validity check and digital signature legitimacy check in the second check are the same as the check process in the first check, and will not be repeated here.

[0175] The technical solution of this embodiment obtains the first user information of the first user, and determines the green certificate information or carbon emission rights information of the first user based on the first user information, so as to determine the green certificate identifier, green certificate timestamp and green certificate file data corresponding to the first user based on the green certificate information of the first user, calculate the green certificate hash summary corresponding to the first user based on the green certificate identifier, green certificate timestamp and green certificate file data, and determine the green certificate digital signature corresponding to the first user, and then determine the first target file based on the green certificate file data, green certificate identifier, green certificate timestamp, user address information of the first user, green certificate hash summary and green certificate digital signature, so as to generate the green certificate token corresponding to the first user based on the first target file and the user address information of the first user; or determine the carbon emission rights identifier, carbon emission rights timestamp and carbon emission rights file data corresponding to the first user based on the carbon emission rights information of the first user, and calculate the green certificate hash summary corresponding to the first user based on the green certificate identifier, green certificate timestamp and green certificate file data, and determine the green certificate digital signature corresponding to the first user, and then determine the first target file based on the green certificate file data, green certificate identifier, green certificate timestamp, user address information of the first user, green certificate hash summary and green certificate digital signature, so as to generate the green certificate token corresponding to the first user based on the first target file and the user address information of the first user; or determine the carbon emission rights identifier, carbon emission rights timestamp and carbon emission rights file data corresponding to the first user based on the carbon emission rights identifier, carbon emission rights Timestamp and carbon emission rights file data, calculate the carbon emission rights hash summary corresponding to the first user, and determine the carbon emission rights digital signature corresponding to the first user, and then determine the second target file according to the carbon emission rights file data, carbon emission rights identifier, carbon emission rights timestamp, user address information of the first user, carbon emission rights hash summary and carbon emission rights digital signature, so as to generate the carbon emission rights token corresponding to the first user according to the second target file and the user address information of the first user, and then based on the green certificate token or carbon emission rights token, conduct green certificate transactions or carbon emission rights transactions between the first user and the second user, which solves the problem that the transaction process and transaction data in the existing green certificate and carbon emission rights transactions are poorly secure, resulting in the inability to meet the transaction security requirements of green certificates and carbon emission rights, and can improve the security of the transaction process and transaction data in the green certificate and carbon emission rights transactions, thereby meeting the transaction security requirements of green certificates and carbon emission rights.

[0196] The transaction processing platform provided by the embodiment of the present invention can execute the transaction processing method provided by any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of the execution method.

[0197] Example 4

[0198] In order to enable those skilled in the art to better understand the transaction processing method and transaction processing platform of this embodiment, a specific example is used below for illustration.

[0199] In a specific example, Ganache and Truffle, the desktop versions of Ethereum private chains, were used as the basic framework of the transaction processing platform, and the Vue framework was used to build a visual interactive interface for the transaction processing platform.

[0200] Specifically, first create an Ethereum private chain in the Ganache platform and configure the RPC server network address to http: / / 127.0.0.1:8545; secondly, use the ERC721Enumerable and ERC721URIStorage contract code libraries of the Ethereum service platform openzeppelin to write smart contracts, and use truffle compile to compile the smart contracts; then, use truffle migrate to deploy the smart contracts on the Ethereum private chain Ganache, and use the element framework to write the back-end user management program to link to mysql for storing user login data; finally, use the Vue framework to write the front-end visual trading system, which mainly includes: user login, user management, personal asset management, personal information viewing, green certificate and carbon emission rights token issuance, green certificate P2P trading, carbon emission rights P2P trading, green certificate and carbon emission rights joint trading, etc., and use the web3.js interface and smart contract to link.

[0201] The transaction processing platform includes two smart contracts: an NFT-based green certificate trading contract and an NFT-based carbon emission rights trading contract. To convert green certificates into carbon emission rights, the green certificate trading contract can directly call the carbon emission rights trading contract to generate carbon emission rights tokens for users. Specifically, the transaction processing platform built these two smart contracts based on OpenZeppelin's ERC721 library and the contract inheritance of ERC721Enumerable and ERC721URIStorage.

[0202] In the transaction processing platform, computational overhead primarily comes from smart contract gas fees. In a centralized clearing model (i.e., when there are multiple sellers and buyers, the transactions are sorted based on bids and then matched and cleared), smart contract overhead is correlated with the number of participating users. Therefore, the relationship between the contract functions conTrans(), sortConSalers(), and sortConBuyers() and the number of participating users was tested, with the number of buyers and sellers set to 1, 2, 3, 4, and 5, respectively. Since Ethereum's block gas fee is capped at 30,000,000, the maximum number of buyers and sellers that can be accommodated is 35, resulting in a total of 140 participating users. Consequently, the transaction processing platform reduces sorting complexity through quick sorting, increases the number of participating users, and further reduces computational overhead.

[0203] Entities using the transaction processing platform to process transactions may include: the Renewable Energy Management Center, trading entities (i.e., sellers and buyers), and supervisory agencies. The Renewable Energy Management Center manages trading entities and reviews the issuance of green certificates and carbon emission rights. Supervisory agencies review trading entity account information before the end of each quota cycle to ensure token holdings and circulation validity.

[0204] Optionally, the supervisory agency can also monitor the fulfillment of the green certificate quota and carbon emission rights quota of the trading entity during the quota period. Specifically, if the green certificate balance of the trading entity does not reach the specified quota, a buyout penalty will be imposed based on the amount of green certificates that are short of the quota; if the carbon emissions of the trading entity exceed the carbon emission rights quota, the supervisory agency will also impose a buyout penalty on the excess carbon emissions. In other words, if the trading entity does not have enough green certificate quota or carbon emission rights quota at the end of the green certificate quota compliance period, the supervisory agency will force the trading entity to spend money to "buy" back to make up for the shortfall, and the price will be higher than the market price, which is a punitive measure.

[0205] Specifically, renewable energy management centers, trading entities, and supervisory agencies can register on the transaction processing platform to conduct transactions of green certificates and carbon emission rights.

[0206] Specifically, the transaction processing for green certificates and carbon emission rights can include the following: First, when each trading entity registers an account, the transaction processing platform generates an account address for trading green certificate and carbon emission rights tokens. Second, the transaction processing platform generates green certificate tokens and carbon emission rights tokens, and the Renewable Energy Management Center allocates a corresponding number of green certificate tokens and carbon emission rights tokens to each trading entity. The transaction processing platform adds a digital signature and timestamp to the metadata of each green certificate token and carbon emission rights token to ensure the authenticity and security of the tokens during the transaction. Then, each trading entity logs into the transaction processing platform and publishes a transaction request. The seller submits their green certificate tokens and carbon emission rights tokens to the transaction processing platform's transaction list and submits a bid. The buyer submits their green certificate purchase request, the number of carbon emission rights, and the bid, and directly transfers their amount to the smart contract. Finally, the smart contract matches the transaction and completes the matching and clearing.

[0207] Optionally, in another example, each trading entity logs in to the transaction processing platform and publishes a transaction demand. The seller submits the green certificate tokens and carbon emission rights tokens it owns to the transaction list of the transaction processing platform and submits a quotation; the buyer can directly view the transaction list of the transaction processing platform and purchase green certificates and carbon emission rights tokens.

[0208] In this embodiment of the present invention, the transaction processing platform leverages blockchain technology to address security, resource underutilization, credibility, and inefficiency issues in traditional trading markets. The transaction processing platform uniquely identifies green certificates and carbon emission rights through non-fungible tokens, and, in conjunction with trading mechanisms, optimizes resource allocation to ensure fair and reliable transactions. The transaction processing platform can support joint transactions between multiple buyers and sellers, reducing transaction costs and improving efficiency.
