Research on Blockchain Consensus Mechanism Based on Improved PBFT Algorithm

文章探讨了基于改进实用拜占庭容错(Practical Byzantine Fault Tolerance,PBFT)算法的区块链共识机制。首先,深入探讨传统PBFT算法的原理和特点;其次,提出一种新的多层次优化PBFT算法,该方法包括节点组划分、层次视图、多层次消息传递等;最后,进行实验分析。实验结果表明,与标准PBFT算法相比,多层次优化PBFT算法在吞吐量、延迟、事务成功率等关键性能指标上均有更好的表现。

The article explores the blockchain consensus mechanism based on the improved Practical Byzantine Fault Tolerance(PBFT)algorithm.Firstly,delve into the principles and characteristics of traditional PBFT algorithms.Secondly,a new multi-level optimization PBFT algorithm is proposed,which includes node group partitioning,hierarchical views,multilevel message passing,etc.Finally,conduct experimental analysis.The experimental results show that compared with the standard PBFT algorithm,the multi-level optimized PBFT algorithm performs better in key performance indicators such as throughput,latency,and transaction success rate.
