Storage system of power grid enterprise based on PBFT blockchain technology
Dianxin kexue, 2021 A blockchain technology based on practical Byzantine fault tolerance (PBFT)algorithm was proposed.First of all, the traditional practical Byzantine fault tolerant algorithm was explained.The traditional algorithm included six phases: pre-stage, demand ...

PBFT Consensus Algorithm Based on Reputation Value Voting and Random Number Election [PDF]
Jisuanji gongcheng, 2022 Compared with Raft and Paxos, the original consensus algorithm, i.e., the Practical Byzantine Fault Tolerant(PBFT) algorithm, is mainly aimed at malicious nodes in a distributed system used to send error messages to other nodes, disturbing the normal ...
