When you hear Raft, a consensus algorithm designed to manage replicated logs in distributed systems. Also known as Raft consensus protocol, it’s not a cryptocurrency—but it’s the quiet engine behind many blockchain networks that need reliable, fast agreement without mining. Unlike Bitcoin’s proof-of-work, Raft doesn’t burn electricity. It doesn’t need miners. It just needs a group of nodes to agree on the same order of events—like a team deciding who gets the next turn in a game, but with zero room for cheating.
Raft is built for simplicity. It splits roles into leader, follower, and candidate. One node leads, others follow, and if the leader disappears, a new one is elected quickly. That’s why it’s used in enterprise blockchains, private networks, and even some DeFi backends where speed and predictability matter more than decentralization. You won’t find Raft on public chains like Ethereum or Solana—they use other methods. But if you’re using a private blockchain for supply chain tracking, identity verification, or internal finance systems, Raft is probably running under the hood. It’s also the backbone of tools like Hyperledger Fabric and etcd, which power Kubernetes clusters and other critical infrastructure.
People often confuse Raft with Byzantine Fault Tolerance (BFT) or Proof of Stake. But Raft assumes nodes won’t act maliciously—it’s crash-tolerant, not Byzantine-tolerant. That makes it faster, but only safe in trusted environments. If someone controls half your nodes, Raft breaks. That’s why it’s rarely used in public crypto. But in the world of enterprise blockchains, where you know who’s running the servers, Raft is a workhorse. And that’s exactly why you’ll find posts here that dig into how Raft compares to PBFT, how it’s adapted for crypto use cases, and which real projects rely on it to keep data consistent across continents.
Below, you’ll find real analyses of blockchain systems that use Raft—or avoid it. You’ll see how it stacks up against other consensus methods, what happens when it fails, and why some crypto teams quietly choose it over flashy alternatives. No hype. No coin promises. Just clear, technical breakdowns of how Raft actually works in practice—and where it belongs.
