Title: HotStuff Authors: Maofan Yin; Dahlia Malkhi; Michael K. Reiter; Guy Golan Gueta; Ittai Abraham Venue: ACM Symposium on Principles of Distributed Computing (PODC) Year: 2019 Canonical: doi:10.1145/3293611.3331591 URL: https://doi.org/10.1145/3293611.3331591 Collector: openalex OA: true ABSTRACT We present HotStuff, a leader-based Byzantine fault-tolerant replication protocol for the partially synchronous model. Once network communication becomes synchronous, HotStuff enables a correct leader to drive the protocol to consensus at the pace of actual (vs. maximum) network delay--a property called responsiveness---and with communication complexity that is linear in the number of replicas. To our knowledge, HotStuff is the first partially synchronous BFT replication protocol exhibiting these combined properties. Its simplicity enables it to be further pipelined and simplified into a practical, concise protocol for building large-scale replication services.
