Abstract

The invention discloses an improved PBFT consensus method and device, an intelligent terminal and a storage medium, and the improved PBFT consensus method comprises the steps: initializing the integrals of all nodes; based on the integral of each node and a preset target number, selecting and obtaining board nodes and common nodes, wherein the board nodes are used for executing a consistency protocol; executing a consensus process based on the board nodes and the common nodes, and updating the integral of the board nodes and the common nodes based on the performance of executing the consensus process by the board nodes and the common nodes; and re-electing and updating the board nodes and the common nodes based on a preset updating period, a preset target number and the updated integrals of the board nodes and the common nodes. According to the improved PBFT consensus method provided by the scheme of the invention, the communication consumption is reduced, and the time cost of the block chain is reduced.

Description

technical field [0001] The present invention relates to the technical field of blockchain, and in particular to an improved PBFT consensus method, device, intelligent terminal and storage medium. Background technique [0002] Blockchain is a decentralized distributed ledger, which has the characteristics of decentralization, stability and immutability. At present, the blockchain is developing rapidly, and the consensus method is widely concerned as an important part of the blockchain. Consensus is mainly divided into eventual consistency consensus algorithms, such as workload proof (POW, Proof of work) algorithm, share-based proof algorithm (POS) and delegated proof of stake algorithm (DPOS), etc., strong consistency algorithm, such as Paxos algorithm And practical Byzantine fault tolerance (PBFT) algorithm, etc. Among them, the PBFT algorithm is currently the most widely used algorithm in the alliance chain. [0003] In the prior art, the PBFT algorithm divides the nodes...
