Every blockchain platform claims its consensus algorithm is the best. But "best" depends on three things: what failure model you need to tolerate, how many nodes you're running, and how comfortable your team is with complexity.

Here's a practical, ranked-by-usefulness breakdown of the five consensus algorithms that matter for enterprise blockchain in 2026.

Consensus is the hardest problem in distributed systems, and blockchain platforms make it harder by treating every consensus algorithm choice as a religious debate. PBFT loyalists dismiss Raft as "not real consensus." Raft proponents point out that PBFT adds complexity most enterprise networks don't need.

The truth: for enterprise consortiums where all participants are known and bound by legal agreements, Raft-based Crash Fault Tolerance (CFT) is the pragmatic choice. Here's why, how it works, and when you actually need Byzantine Fault Tolerance (BFT).
