EBFT: Simplifying BFT Consensus Through Egalitarianism
- Published
- Record updated
Summary
EBFT is a BFT consensus framework for permissioned blockchains that replaces a fixed leader with randomly and non-interactively proposed blocks, combining Nakamoto's longest-chain rule with classical BFT quorum voting. The authors built three protocols (EBFT-Syn, EBFT-PSyn and EBFT-Turbo) atop btcd, with about 920 lines of code, and evaluated them on EC2 with up to 256 nodes. EBFT-Syn and EBFT-PSyn reach latencies of 6 and 1 seconds, while EBFT-Turbo processes up to 3.2k transactions per second at 8 seconds latency.
