Federated Byzantine Fault Tolerance (fBFT) is a consensus mechanism designed to maintain network integrity even if some nodes act maliciously. It relies on a selected group of trusted nodes (a federation) to validate transactions and produce blocks.

How It Works

In an fBFT system, only a predefined subset of nodes participates in consensus. These nodes are chosen for their reliability and performance. The protocol ensures that as long as a majority of these selected nodes behave honestly, the system remains secure and functional.

Role in Blockchain Networks

fBFT is used in permissioned or consortium blockchains where decentralization is less of a priority than speed and efficiency. It enables faster transaction finality and better scalability than traditional Proof-of-Work systems.
