Problems solved by technology

[0005] In pbft, it is a three-stage consensus process, that is, a block needs to go through three stages from the proposal to the confirmation process, each stage requires at least 2f+1 nodes to reach a consensus, and the confirmation of a block requires consensus Three times, the consensus efficiency is low and the speed is slow

Abstract

The invention provides a data consensus method and device based on a block chain, electronic equipment and a storage medium, the method is executed by any block chain node in a block chain network, and the method comprises the following steps: according to the serial number of the node and the current consensus round, judging whether the node is a block-out node; if the node is a block-out node, obtaining transaction data from a transaction pool, and packaging the transaction data to generate a first block; broadcasting the first block to a plurality of consensus nodes in the block chain network, so that the consensus nodes verify the first block and broadcast an execution result of the first block; and receiving execution results of the first block broadcasted by the plurality of consensus nodes, and if the execution results of the first block broadcasted by the consensus nodes exceeding a specified proportion are the same as the execution results of the node executing the first block, determining that the first block passes the consensus. According to the scheme, consensus efficiency can be improved, and consensus time is shortened.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a blockchain-based data consensus method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] Byzantine fault tolerance technology is a kind of fault tolerance technology in the field of distributed computing. The Byzantine assumption is a modeling of the real world, where computers and networks may behave unpredictably due to hardware errors, network congestion or outages, and malicious attacks. Byzantine fault-tolerant techniques are designed to handle these abnormal behaviors and meet the specification requirements of the problem to be solved. [0003] Currently, pbft (Practical Byzantine Fault Tolerant Algorithm) is used as the consensus algorithm of the alliance chain. The PBFT algorithm can guarantee that if there are 3f+1 nodes, even if there are f errors or no response, the correct result of the consensus c...
