Brief Announcement: It’s not easy to relax: liveness in chained BFT protocols

pdf-format:
LIPIcs-DISC-2022-39.pdf (0.5 MB)


Abstract

Modern chained BFT SMR protocols have poor liveness under failures as they require multiple consecutive honest leaders to commit a single block. Siesta, our proposed new BFT SMR protocol, is instead able to commit a block that spans multiple non-consecutive honest leaders. Siesta reduces the expected commit latency of HotStuff by a factor of three under failures, and the worst-case latency by a factor of eight.
