Abstract

The invention discloses a Byzantium fault-tolerant consensus optimization method for a block chain. The method comprises the following steps: S1, performing voting weight table initialization; S2, processing transaction; S3, electing a main node; S4, verifying a REQUEST message; S5, broadcasting a PRE-PREPARE message; S6, verifying the PRE-PREPARE message; S7, performing voting; S8, broadcasting the PREPARE message containing a voting value; S9, recording the message and the number of voting to a local log; S10, performing weighted sum on the voting value, and performing nonlinear processing;S11, broadcasting the COMMIT message; S12, verifying the COMMIT message; S13, writing the current block into a local account book, and replying a client. The problem that the method disclosed by the invention is limited in application scene, low in security, needs to consume a large amount of communication resources and is large in system resource consumption in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a Byzantine fault-tolerant consensus optimization method for blockchain. Background technique [0002] In 2008, Satoshi Nakamoto published an article titled "Bitcoin: A Peer-to-Peer Electronic Cash System", announcing the birth of Bitcoin, and the key technology, blockchain, gradually attracted everyone's attention. Blockchain is a distributed ledger technology. Data is stored in a series of blocks. Blocks are connected according to time stamps. Cryptography is used to ensure the security of data transmission and access. Smart contracts formed by automated script codes to conduct business. The development of blockchain will subvert the traditional network service form and make completely decentralized system services possible. [0003] In the blockchain technology ecology, the consensus algorithm is the most critical part. Consensus is an algorithm th...
