Super account book fabric-based transaction method and system

Abstract

The invention provides a super account book fabric-based transaction method and system. The method comprises the following steps that: whether a national password encryption algorithm is configured and used in a configuration file is judged; when the national cryptographic encryption algorithm is configured and used, a national cryptographic encryption algorithm suite is loaded, otherwise, an international encryption algorithm suite is loaded; a transaction is initiated, and a transaction signature is generated on the transaction according to a signature function in the encryption algorithm suite, wherein the encryption algorithm suite is the national secret encryption algorithm suite or the international encryption algorithm suite; the transaction on which the transaction signature has been generated is sent to a plurality of endorsement nodes in a blockchain network; transaction results from each endorsement node are received; an endorsement signature on each transaction result is verified according to a signature verification function in the encryption algorithm suite; the transaction on which the transaction signature has been generated and the verified transaction results areassembled into transaction information; and the transaction information is sent to a sorting node in the blockchain network. With the method and system of the invention adopted, two blockchain networks can be flexibly docked, and implementation cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of super ledger, in particular, to a transaction method and system based on super ledger fabric. Background technique [0002] Hyperledger (super ledger) Fabric is a distributed ledger platform for enterprises. It introduces authority management and supports pluggable and extensible design. It is the first open source project for alliance chain scenarios. Hyperledger Fabric currently has many application cases in finance, trade and other fields. [0003] Cryptographic algorithms play a pivotal role in blockchain systems. Cryptographic algorithms are widely used in many functions such as the authentication module in Hyperledger Fabric and the Merkle Tree in the blockchain. [0004] The cryptographic algorithms used in Hyperledger Fabric are international general cryptographic algorithms. There are a large number of uncontrollable factors in these algorithms. Once they are used by criminals to attack...

AI Technical Summary

Problems solved by technology

[0005] The existing Hyperledger Fabric java SDK (Software Development Kit, software development kit) cannot communicate with the Hyperledger Fabric blockchain that supports national secret algorithms

If a separate Hyperledger Fabric java SDK is optimized to communicate with the Hyperledger Fabric blockchain network that supports national secret algorithms, it is a different version or program branch from the Hyperledger Fabric java SDK that supports international general cryptographic algorithms, which is not convenient for unified maintenance

At the same time, the application blockchain client program needs to be modified accordingly, which increases the implementation cost
