Abstract

Blockchain technology is a distributed ledger technology that can be employed to safeguard user privacy and ensure the integrity of data, thereby enhancing information security. Traditional algorithms, such as Raft, have been criticized for their limited ability to provide sufficient Byzantine Fault Tolerance (BFT) and vote splitting in this context. To overcome these issues, PS-Raft relies on three key innovations. Firstly, it limits the number of potential Candidates by carefully selecting nodes based on their communication conditions. Secondly, it utilizes an SM2-based proxy signature algorithm to verify the legitimacy of Candidate and Leader identities. Lastly, during term replacement and log replication, it ensures the honesty of Leader by verifying log data. We conducted a local cluster simulation that compared the performance of PS-Raft and Raft consensus algorithms. The results of experiment demonstrate that PS-Raft effectively screens and defends against Byzantine nodes while maintaining comparable overall performance to Raft. This improves hardware and time efficiency for Byzantine nodes attempting to implement such attacks. Furthermore, the PS-Raft algorithm significantly reduces the election time and resolves the problem of vote splitting.
