基于节点识别的改进拜占庭容错共识算法
Improved Byzantine Fault-tolerant Consensus Algorithm Based on Node Recognition
摘要
Abstract
The practical Byzantine fault tolerance(PBFT)algorithm applied to the alliance chain has some problems,such as arbitrary selection of master nodes and high communication overhead.To solve these problems,an improved Byzantine fault-tolerant consensus algorithm(NR-PBFT)based on node recognition is proposed.Firstly,the consistency process is optimized by introducing BLS aggregate signature.Secondly,CatBoost algorithm is used to identify nodes,select high-reputation nodes as the primary nodes,and dynamically process low-reputation nodes.Experimental results show that NR-PBFT is superior to PBFT and ABFT in security,throughput and delay.关键词
