Consensus mechanism operation method applied to alliance chain

Abstract

The invention discloses a consensus mechanism operation method applied to an alliance chain. The method comprises the following steps of dividing nodes in the alliance chain into a plurality of slaveconsensus sets, except the last slave consensus set, enabling the number of nodes of each of the rest slave consensus sets to be the same; when a node wants to join in or quit the consensus, executinga JION or EXIT protocol; selecting a master node of each slave consensus set according to a longest chain principle; when the preparation message sent by the main node is abnormal, executing a view switching protocol; executing a consistency protocol in each slave consensus set, and after local consensus is consistent, entering a master consensus set composed of all master nodes to execute the consistency protocol, i.e., performing global consensus; and after the global consensus is consistent, finishing the transaction consensus. According to the method, consensus efficiency of an alliance chain under the condition of large node scale can be effectively improved, the communication overhead is reduced to a certain extent, dynamic change of system nodes can be realized, and a certain system error-tolerant rate, safety and activeness are further ensured.

Description

technical field [0001] The invention belongs to the field of block chain consensus mechanism, and specifically relates to a consensus mechanism operation method applied to alliance chain. Background technique [0002] At present, blockchain technology has attracted widespread attention due to its characteristics of decentralization, trustlessness, and immutability. With different application scenarios, a large number of domestic and foreign scholars are studying blockchain-related technologies to meet different needs. The current types of blockchains include public chains, private chains, and alliance chains. In December 2015, the Linux Foundation launched the Hyperledger open source blockchain project, which is dedicated to the development of blockchains between enterprises, namely alliance chains. . The alliance chain has a strict identity review mechanism, and the probability of node failure is small, so it has a good application prospect. [0003] Due to the high netwo...

Problems solved by technology

[0004] Purpose of the invention: In order to overcome the problems in the existing technology that the consensus time of the mechanism is long, the network overhead in the consensus process is large, and the consensus efficiency is not high when the node scale is large, provide a consensus applied to the alliance chain mechanism, which is based on the PBFT consensus mechanism and proposes a multi-center dynamic consensus mechanism (Multi-center Dynamic PBFT, MCDPBFT)
