ParBFT: Faster Asynchronous BFT Consensus with a Parallel Optimistic Path

ePrint Report: ParBFT: Faster Asynchronous BFT Consensus with a Parallel Optimistic Path

Xiaohai Dai, Bolin Zhang, Hai Jin, Ling Ren

To reduce latency and communication overhead of asynchronous Byzantine Fault Tolerance (BFT) consensus, an optimistic path is often added, with Ditto and BDT as state-of-the-art representatives. These protocols first attempt to run an optimistic path that is typically adapted from partially-synchronous BFT and promises good performance in good situations. If the optimistic path fails to make progress, these protocols switch …
