DETAILED DESCRIPTION

[0017] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0018] In the description of the present invention, it is to be understood that the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the feature. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0019] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fixed connection" and "fixed connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0020] The specific implementation of the present invention is described in detail below in conjunction with preferred embodiments.

[0021] This embodiment discloses a commodity carbon label management system based on blockchain, including: A blockchain network is used to store and manage commodity carbon emission data; the blockchain network is a public chain, a private chain or a joint chain. Preferably, the blockchain network is implemented in the form of a public chain, because it is transparent, decentralized and open, and can ensure that all participants can access and verify carbon emission data, thereby increasing the trust of the system. The public chain can also encourage more participants to join, thereby promoting data sharing and cooperation. During the commodity production process, carbon dioxide emission data is monitored and collected in real time through sensors, monitoring equipment or other means.

[0022] Accounting nodes are used to write commodity carbon emission data and access policies into the blockchain ledger; when receiving new carbon emission data, the accounting node first verifies the data to ensure its accuracy and completeness. Verification can include checking the data format, source, and integrity. The verified data will be packaged into blocks. Each block contains a certain number of transactions (in this case, carbon emission data), as well as a hash value pointing to the previous block to ensure the order of the data and the integrity of the chain. The hash function H converts the block data D into a fixed-length hash value h: h=H(D). Once the new block is packaged and verified, the accounting node adds it to the blockchain and updates the status of the blockchain.

[0023] Accounting nodes are also responsible for developing and storing access policies. For example, an access policy can be defined as a permission list that specifies which users can access specific carbon emission data, ensuring the data is tamper-proof and complete.

[0024] The data encryption module is used to encrypt the collected carbon emission data. Specifically, the data encryption module uses an asymmetric encryption algorithm to encrypt the carbon emission data to ensure the security and confidentiality of the data. The asymmetric encryption algorithm uses a pair of keys: a public key and a private key. Its basic principles are as follows: Key generation: The user generates a pair of keys: Public key (PK): can be shared publicly and used to encrypt data. Private key (SK): must be kept confidential and only held by the user himself, used to decrypt data.

[0025] Encryption process: Assume that user A needs to send data M to user B. User A uses user B's public key Encrypted Data:

[0026] Among them, C is the encrypted data.

[0027] Decryption process: After user B receives the encrypted data CCC, he uses his own private key To decrypt:

[0028] Wherein, D represents the decryption operation.

[0029] The access control module is used to formulate access policies for commodity carbon emission information and implement authorized access control; its main components include: Access policy formulation: clearly define which users can access specific data, usually distinguishing permissions by roles (such as administrators, producers, consumers). Access policies can be based on attributes (such as user identity, data type) or rules (such as time restrictions, location restrictions). Authorization mechanism: When a user requests access to data, the module verifies their identity and checks their permissions. Use Boolean logic or access control lists (ACLs) to determine whether a user has access rights. Logging: Record the time, user identity, and access results of each access request for auditing and tracing.

[0030] A smart contract is a self-executing contract whose terms and conditions are written into the blockchain in the form of code. Key features include: Automatic execution: Smart contracts are able to execute automatically when certain conditions are met, without the intervention of an intermediary or third party. This increases efficiency and reduces the risk of errors. Transparency and immutability: Once a contract is deployed on the blockchain, the terms are public and cannot be changed, ensuring that all parties follow the contract. Conditional logic: Smart contracts can contain complex logic, allowing multiple conditions to be checked. For example, it can be set that a certain carbon emission data can only be accessed when the user's identity is verified.

[0031] The access control module implements authorized access control of commodity carbon emission information through smart contracts. In this system, the access control module is used in conjunction with smart contracts to create smart contracts to define access policies, including which users can access which data, and conditions (such as whether fees are paid, whether a specific time period is met, etc.) to ensure that only authorized users can access relevant information. Access records will be automatically recorded on the blockchain, providing a transparent audit trail to ensure compliance and security.

[0032] The user interface is used for users to scan the QR code to obtain the carbon emission information of the product. Specifically, the user interface provides real-time query, sharing and tracing functions of the carbon emission information of the product to meet the user's demand for data.

[0033] The present invention also discloses a commodity carbon label management method based on blockchain, comprising the following steps: a. Collect carbon emission data in real time during the production process of goods and encrypt it; Carbon emission data is digitally signed before being uploaded to the blockchain network to ensure the authenticity and integrity of the data.

[0034] b. Upload the encrypted carbon emission data to the blockchain network and formulate an access policy. Specifically, the access policy includes provisions on data access rights, such as limiting access to specific data to specific users or roles.

[0035] c. Submit the access policy to the accounting node and write it into the blockchain ledger; d. Users scan the QR code on the product and obtain the carbon emission information of the product through the user interface, including detailed production process and related data.

[0036] The user interface provides data sharing and traceability functions, allowing users to understand the production process of products and related carbon emissions.

[0037] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
