[0072] In another specific implementation of this invention, the carbon emission evidence storage blockchain 5 is specifically used to extract the corresponding first network identifier, first evidence storage ciphertext, and first evidence storage signature from the first evidence storage data when performing evidence storage block creation processing based on the first evidence storage data and the authorization management module 1; send the first evidence storage processing application carrying the first network identifier and the first evidence storage signature to the authorization management module 1; receive the first signature plaintext and the second network public key returned by the authorization management module 1; when the first signature plaintext and the second network public key are not empty, decrypt the first evidence storage ciphertext based on the second network public key and use the decryption result as the corresponding third decrypted plaintext; perform hash calculation on the third decrypted plaintext based on the specified first hash algorithm to obtain the corresponding fourth hash code; when the fourth hash code matches the first signature plaintext, extract the corresponding first timestamp and the first network carbon emission total from the third decrypted plaintext; and generate a new evidence storage block based on the first network identifier, the first timestamp, and the first network carbon emission total and perform the corresponding block on-chain operation.

[0073] Here, the carbon emission evidence storage blockchain 5 of this invention can be implemented based on various commonly used blockchain specifications, the most common being the Ethereum blockchain specification. These commonly used blockchain specifications all provide standard block on-chain operation interfaces, which will not be elaborated here. However, the data formats of the corresponding block headers and block bodies also differ depending on the blockchain specification used. Therefore, the specific positions of the first network identifier, first timestamp, and first network carbon emission total in the block header and / or block body for each on-chain operation depend on the specific blockchain specification used and can be configured according to the specific implementation. If it is the Ethereum blockchain specification, the first network identifier and first timestamp will be placed in the block header, while the first network carbon emission total will be placed in the block body.

[0074] In another specific implementation of this invention, the carbon emission evidence storage blockchain 5 is specifically used to extract the corresponding first query customer identifier, first query ciphertext and first query signature from the first query data when the corresponding first query feedback data is obtained by performing evidence storage block query processing based on the first query data and the authorization management module 1 and sent back to the corresponding customer query terminal 4.

[0075] The system sends a first query processing application, carrying the first query client identifier and the first query signature, to the authorization management module 1; receives the second signature plaintext and the second client public key returned by the authorization management module 1; and when both the second signature plaintext and the second client public key are not empty, it decrypts the first query ciphertext based on the second client public key and uses the decryption result as the corresponding fourth decrypted plaintext; it performs a hash calculation on the fourth decrypted plaintext based on the specified first hash algorithm to obtain the corresponding fifth hash code; and when the fifth hash code matches the second signature plaintext, it uses the fourth decrypted plaintext as the corresponding first blockchain query instruction.

[0076] When the first blockchain query instruction is not empty, the corresponding blockchain query operation is executed based on the first blockchain query instruction to obtain the corresponding first query result; the first query result is used as the corresponding first query plaintext; the first query plaintext is encrypted with the second client public key and the encryption result is used as the corresponding first feedback ciphertext; the first query plaintext is hashed based on the specified first hash algorithm to obtain the corresponding sixth hash code; the first signature processing application carrying the sixth hash code is sent to the authorization management module 1; the first feedback signature sent back by the authorization management module 1 is received; and the first query customer identifier, the first feedback ciphertext and the first feedback signature are combined to form the corresponding first query feedback data and sent back to the corresponding client query terminal 4.

[0077] Here, the first blockchain query instruction in this embodiment of the invention includes a first query network identifier set, a first query type, and a first query parameter; the first query network identifier set includes multiple first query network identifiers; the first query type includes at least a first type and a second type; when the first query type is the first type, the corresponding first query parameter is empty; when the first query type is the second type, the corresponding first query parameter is a specified time period.

[0078] In another specific implementation of this invention, the carbon emission evidence storage blockchain 5 is specifically used to extract the corresponding first query network identifier set, first query type, and first query parameters from the first blockchain query instruction when the corresponding blockchain query operation is executed based on the first blockchain query instruction to obtain the corresponding first query result; and to send the first permission verification application carrying the first query customer identifier and the first query network identifier set to the authorization management module 1; and to receive the first verification result returned by the authorization management module 1; and to identify the first verification result; if the first verification result is no permission, then the corresponding first query result is set to a preset query permission not satisfied prompt message; if the first verification result is authorized, then the first query type is identified; if the first query type is a first type, then the evidence storage blocks on the blockchain corresponding to each first query network identifier of the first query network identifier set and with the latest on-chain time are extracted to form the corresponding first query result; if the first query type is a second type, then the evidence storage blocks on the blockchain corresponding to each first query network identifier of the first query network identifier set and with the on-chain time satisfying the first query parameters within a specified period are extracted to form the corresponding first query result; wherein, the first verification result includes authorized and unauthorized.

[0079] In summary, this invention provides a carbon emission data processing system based on a charging network, comprising: an authorization management module, multiple concentrators, multiple charging networks, multiple customer query terminals, and a carbon emission evidence blockchain. Each charging network includes one or more charging piles, each continuously measuring its total electricity consumption and updating its total carbon emissions. Each concentrator corresponds one-to-one with a charging network, periodically collecting the total carbon emissions of all charging piles within the network and calculating the corresponding total network carbon emissions, which are then transmitted to the carbon emission evidence blockchain for storage. Customer query terminals assigned to different customers can obtain carbon emission information for each charging network by querying the carbon emission evidence blockchain. This invention solves the problem that most charging networks currently lack dedicated carbon emission data processing systems, enabling continuous collection and tracking of carbon emissions generated during network operation.
