How Raft Tackles the Byzantine Generals Problem
This article explains the Byzantine Generals problem, its fault‑tolerant challenges in distributed systems, and how the Raft consensus algorithm addresses these issues by using leader election, log replication, and safety mechanisms, while also comparing Raft with other algorithms such as Paxos, ZAB and PBFT.
4. Conclusion
Raft provides a widely adopted, strong‑consistency, leader‑based solution for distributed systems. By separating consensus into leader election, log replication, and safety, it achieves high availability, fault tolerance, and data consistency across clusters.
