Transaction backup method and system based on block chain

Abstract

The invention provides a transaction backup method and system based on a block chain. The transaction backup method based on the block chain comprises the steps that a main verification node receivesa transaction request, executes an intelligent contract corresponding to the transaction request, and broadcasts a generated main transaction result and the transaction request to other main verification nodes in the main block chain to perform transaction consensus; the main verification node judges whether the transaction consensus is successful or not according to consensus confirmation information from other main verification nodes; when the transaction consensus succeeds, writing in the main transaction result, and transmitting the main transaction result and the transaction request to astandby verification node corresponding to the main verification node; the standby verification node executes the intelligent contract corresponding to the transaction request, and compares the generated slave transaction result with the master transaction result; and when the master transaction result is the same as the slave transaction result, writing the master transaction result. According tothe method, the cross-areaal high-availability deployment requirement of the block chain can be met on the premise of not influencing the consensus efficiency of the block chain.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a transaction backup method and system based on block chains. Background technique [0002] The blockchain system is a brand-new distributed database accounting system that stores data in a block chain structure and uses distributed nodes for data consensus. As a sharp tool to solve business pain points such as "information islands, lack of trust, and difficult collaboration" in traditional business systems, it basically adopts the operation mode of the alliance chain in practical applications. Due to technical problems such as high performance guarantees required by business systems, most enterprises adopt centralized hosting and deployment of blockchain networks to conduct centralized operations in the same network area. [0003] In the existing technology, the blockchain nodes are redundantly deployed in the cross-regional backup computer room to ensure the cross...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the blockchain nodes are redundantly deployed in the cross-regional backup computer room to ensure the cross-regional high availability of the blockchain network. However, with the increase in the number of blockchain consensus nodes, the blockchain network is processing smart contract logic. The time consumption of consensus calculation will also increase, and the delay consumption of cross-regional network communication will greatly reduce the consensus efficiency of the blockchain network
