Survey on Byzantine Fault Tolerance Accountability Mechanisms
The Byzantine Fault Tolerance(BFT)protocol plays a crucial role in ensuring the consistency and reliability of blockchain or distributed systems in the face of node failures and malicious behavior.The BFT accountability mechanism aims to identify Byzantine nodes by recording and sharing the behavior of consensus nodes during the consensus process.It is designed to effectively address the security and liveness issues that traditional BFT protocols cannot guarantee when the number of Byzantine nodes exceeds 1/3.This paper systematically summarized existing BFT accountability protocols,including server-side accountability mechanisms,client-side accountability mechanisms,and embedded BFT accountability mechanisms.Through a comprehensive comparison and analysis of these involved mechanisms,this paper delved into the challenges and anticipated possible future directions.
