Fast Byzantine Fault Tolerance (FBFT)
Fast Byzantine Fault Tolerance (FBFT) is a popular consensus mechanism used in Proof-of-Stake (PoS) blockchains. It enhances efficiency by allowing the block leader to gather votes from validators through a multi-signature signing process, eliminating the need for all validators to broadcast their votes. This approach enables faster and more scalable consensus compared to pBFT-based chains.
