[0048] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] See also Figure 1 The carbon credit trading method according to the embodiment of the present invention comprises the following steps:

[0050] Step S100: Receive project details information of the current project.

[0051] Specifically, the embodiment of the present application can be designed as a platform, where a project developer creates an account on the platform and submits project details information. After the platform receives the project details information of the current project, it verifies the project.

[0052] like Figure 1 As shown, the carbon credit trading method also includes the following steps:

[0053] Step S200: Evaluate the current project according to the project details information to obtain an evaluation result of the current project.

[0054] In the embodiment of the present application, the step S200 specifically includes:

[0055] Step S210: Perform integrity check on the project details information according to a preset integrity check rule to obtain an integrity level;

[0056] Step S220, obtaining a rating result obtained after carbon credit rating of the current project;

[0057] Step S230: searching a preset scoring matrix according to the integrity level and the rating result to obtain an evaluation result of the current project.

[0058] Specifically, a third-party verification agency can be used to conduct a carbon credit rating on the current project, that is, the project details are uploaded to the third-party verification agency to obtain the rating results of the carbon credit project. The rating results are uploaded to the platform system for comprehensive evaluation.

[0059] It is understandable that the integrity level can be an integrity score, such as 0, 1, 2, and 3. The rating result of the verification agency can be recorded as an external score, such as 0, 1, 2, and 3. 0 is the worst rating and 3 is the best rating. The scoring matrix can be shown in Table 1.

[0060]

[0061] Table 1

[0062] The embodiment of the present application detects the project details information through the preset integrity detection rules, which can ensure that the submitted project information is complete and accurate, and reduce the evaluation bias caused by missing or incorrect information. This helps to improve the accuracy and reliability of subsequent evaluations; and, the integrity level of the project is combined with the carbon credit rating results, and the evaluation results are obtained by searching the preset scoring matrix, which combines quantitative and qualitative factors to make the evaluation process more comprehensive. Since the embodiment of the present application is an automated evaluation process, it also improves the efficiency of the entire carbon credit trading process.

[0063] In one embodiment of the present application, the project details information includes: project submission information and project material documents; the project submission information includes: project name, project location, project type and carbon emission reduction. Step S210 specifically includes:

[0064] Step S211, detecting whether the location of the project is land, and obtaining a location rationality detection result;

[0065] Step S212: Detect whether the project type belongs to a preset project type standard library, and if so, obtain a project type detection result;

[0066] Step S213: using text recognition technology to identify the project location and project type in the project material document, and detecting whether the identified project location and project type are consistent with the project location and project type in the project submission information, thereby obtaining an information matching detection result;

[0067] Step S214: Determine the integrity level according to the location rationality detection result, the project type detection result and the information matching detection result.

[0068] The standard library of preset project types includes: renewable energy projects, avoided deforestation projects, afforestation and reforestation projects, industrial gas emission reduction projects and energy efficiency improvement projects.

[0069] Specifically, first check whether the geographical location is reasonable, and determine whether it belongs to land according to the uploaded latitude and longitude. If it belongs to land, it is reasonable; then check whether the project type belongs to the type included in the system; then use text recognition technology to extract information in the document, filter out location information and type, and check whether the information in the document is consistent with the uploaded information. If all three items are passed, the best rating is 3 points. If all three items are not passed, the worst rating is 0 points, as shown in Table 2.

[0070]

[0071]

[0072] Table 2

[0073] The embodiment of the present application can ensure that the submitted project is carried out within a reasonable geographical scope by detecting whether the location of the project is on land, thereby avoiding the mixing of false or invalid projects. At the same time, verifying whether the project type belongs to the preset project type standard library can ensure that the project type meets the prescribed scope and enhance the accuracy of the data. In addition, by using text recognition technology to identify key information in the project material document and compare it with the content in the project submission information, it can be checked whether the two are consistent. This double verification method greatly enhances the consistency of information and reduces information differences caused by human input errors or tampering.

[0074] like Figure 1 As shown, the carbon credit trading method also includes the following steps:

[0075] Step S300: If the assessment result is that the project has passed the verification, a corresponding carbon credit asset is generated according to the carbon emission reduction in the project details information.

[0076] In the embodiment of the present application, the step S300 specifically includes:

[0077] Step S310: If the evaluation result is that the project has passed the verification, the current project is approved based on the pre-deployed smart contract, and a project identifier of the current project is generated;

[0078] Step S320: Record the project identifier on the blockchain where the smart contract is located;

[0079] Step S330: convert the carbon emission reduction in the project details information into carbon credit tokens according to a preset conversion rule, and a number of the carbon credit tokens constitute the carbon credit assets of the current project.

[0080] Specifically, if the verification is passed, the smart contract automatically approves the project and generates a unique project identifier to be recorded on the blockchain, making the project information visible to all participants. The preset conversion rules can generate 1 token for every ton of carbon dioxide, ensuring the quantification and standardization of carbon credits and avoiding the risk of double counting, that is, the same carbon credit is used for multiple transactions.

[0081] The embodiment of the present application automatically approves verified projects through pre-deployed smart contracts and generates project identifiers, which greatly improves efficiency and reduces the time and cost of manual operations. At the same time, the distributed ledger characteristics of the blockchain ensure the transparency and traceability of this process. In addition, the project identifier is recorded on the blockchain where the smart contract is located, and the immutability and decentralization of the blockchain are used to ensure the authenticity and security of the project information, thereby enhancing the credibility of carbon credit assets.

[0082] In one embodiment of the present application, each carbon credit token has a unique identifier, a source project, and a generation date. In other words, each token has a unique identifier that records its source project, generation date, and other information, which ensures the uniqueness of the token and prevents duplicate transactions.

[0083] The embodiment of the present application sets a unique identifier for each carbon credit token so that the carbon credit token can be accurately tracked throughout the entire transaction process, including from generation to transaction, and then to the final holder. Each step can be clearly recorded. This traceability helps to ensure the authenticity and legality of the carbon credit token and prevent forgery and reuse. The clear marking of the source project enables market participants to understand the emission reduction projects and specific circumstances behind each carbon credit token. This transparency helps to build trust and make the market more fair and open. At the same time, it also provides investors with more sources of information to help them make more informed decisions. The existence of unique identifiers and generation dates makes the management and auditing of carbon credit tokens simpler and more efficient. Regulators can easily track the flow of tokens and check whether transactions comply with regulations, thereby ensuring market compliance and stability.

[0084] like Figure 1 As shown, the carbon credit trading method also includes the following steps:

[0085] Step S400: Conduct carbon credit transactions based on the carbon credit assets.

[0086] In the embodiment of the present application, the step S400 specifically includes:

[0087] Step S410: when receiving a transaction instruction for the current project, obtaining a set price and transaction conditions for the current project;

[0088] Step S420: Record the set price and transaction conditions on the blockchain;

[0089] Step S430: When a purchase request for a carbon credit token is received, a smart contract is used to conduct a carbon credit transaction on the carbon credit token in the carbon credit asset.

[0090] Specifically, project developers can choose to list carbon credits for trading, set prices and trading conditions, and record the information on the blockchain, visible to all market participants. When executing a transaction, the buyer selects the carbon credit and initiates a purchase request. The smart contract matches the seller with a high bid and finds the buyer with a low bid, automatically matching the buyer and the seller. If the conditions are met, the transaction is automatically executed. The ownership of the token is transferred to the buyer and the funds are transferred to the seller. The transaction details are recorded on the blockchain to ensure transparency.

[0091] The embodiment of the present application records the set price and transaction conditions on the blockchain so that all market participants can view this information openly and transparently. This transparency enhances the fairness and credibility of the transaction and reduces the possibility of information asymmetry and fraud. The use of smart contracts to trade carbon credit tokens can realize the automated processing of transactions without human intervention, greatly improving transaction efficiency and reducing transaction costs and time delays. In addition, smart contracts can also ensure that transactions are automatically executed according to preset rules and conditions, reducing human errors and disputes; the decentralized and tamper-proof characteristics of the blockchain ensure the security of transaction records. Once transaction information is recorded on the blockchain, it cannot be tampered with or deleted, which provides a strong security guarantee for carbon credit transactions and prevents the risk of data being maliciously tampered with or forged.

[0092] In an embodiment of the present application, the carbon credit trading method further includes:

[0093] Analyze the buying and selling order data generated by each project's completed carbon credit transactions to obtain the number of transactions for each carbon credit token;

[0094] If the transaction number of the carbon credit token is greater than the preset transaction number threshold, it is determined that the carbon credit token transaction is abnormal;

[0095] If the number of abnormal carbon credit token transactions under the same project is greater than a preset threshold, the project is determined to be abnormal and the project is reviewed.

[0096] Specifically, the platform system will continuously monitor the performance of all projects. Smart contracts automatically analyze the buy and sell order data, and determine whether there are potential risks or problems through the number of transactions. If a token is traded more than 100 times a day, the token transaction is considered abnormal. If most or all of the tokens under the same project are traded abnormally, the project is considered abnormal. If an abnormality is found, the review process is triggered. When this process is triggered, the system automatically sends an email to the system auditor, who manually checks the account information of both parties to the transaction to determine whether it is a fraudulent transaction. If an account is the buyer or seller of more than 50% of the orders, it is determined to be a fraudulent account and is banned to ensure normal liquidity in the market.

[0097] The embodiments of the present application can detect abnormal trading activities in a timely manner by monitoring the number of transactions of carbon credit tokens. When the number of transactions exceeds the preset threshold, the system can automatically trigger an early warning mechanism to prompt possible abnormal trading behavior. Traditional regulatory methods often require manual review of a large amount of transaction data, which is inefficient and prone to errors. However, through automated analysis of buy and sell order data, abnormal transactions and projects can be quickly identified, reducing the workload of regulators and improving regulatory efficiency. In addition, open and transparent analysis of transaction data can allow market participants to understand the true situation of the market more clearly and reduce the occurrence of information asymmetry and fraud.

[0098] The embodiments of the present application utilize blockchain technology and smart contracts to achieve the whole process management of carbon credit project registration, verification, monitoring, carbon credit generation, trading and cancellation, thereby improving the transparency, efficiency and credibility of carbon credit transactions, reducing transaction costs and fraud risks, ensuring the standardization of carbon credits to a certain extent, improving transaction timeliness, and lowering the threshold for public participation.

[0099] In a specific embodiment of the present application, the principle framework of the platform is as follows: Figure 2 As shown in Figure 1, it includes: external data interface, user interface layer, business logic layer, smart contract layer and blockchain network. The specific process of carbon credit trading method is as follows: Figure 3 As shown, it includes: carbon credit developers publish carbon credit projects through external data interfaces, the business logic layer verifies the projects and uploads smart contracts, and the smart contract layer generates carbon credits and publishes them to the blockchain network. When users freely buy and sell carbon credits through the user interface layer, the business logic layer submits buy and sell orders to the smart contract layer, and the smart contract layer uploads transaction records to the blockchain network. The business logic layer continuously monitors all projects.

[0100] In one embodiment, if Figure 4 As shown, based on the above carbon credit trading method, the present invention also provides a carbon credit trading device, including:

[0103] A generation module 300 is used to generate corresponding carbon credit assets according to the carbon emission reduction in the project details information if the assessment result is that the project has passed the verification;

[0104] The trading module 400 is used to conduct carbon credit transactions based on the carbon credit assets.
