Webof classical Byzantine quorum systems is Bracha broadcast [2]. This implements reliable Byzantine broadcast [3] in a system of 3f +1processes where at most f processes can fail and any 2f +1processes constitute a quorum.

WebThe objective of Byzantine fault tolerance is to be able to defend against failures of system components with or without symptoms that prevent other components of the system from … WebFor asynchronous Byzantine reliable broadcast (BRB), we also investigate the bad-case latency for all non-faulty parties to commit when the broadcaster is faulty but some non-faulty party commits. We provide matching upper and lower bounds on the resilience threshold of bad-case latency for BRB protocols with optimal good-case latency of 2 rounds.
