摘要
Techniques for implementing linear view-change with optimistic responsiveness in a BFT protocol running on a distributed system comprising n replicas are provided. According to one set of embodiments, the replicas can execute, during a view v of the BFT protocol, a first voting round comprising communicating instances of a first type of COMMIT certificate among the replicas. Further, when 2f+1 instances of the first type of COMMIT certificate associated with view v have been received by the replicas, the replicas can execute a second voting round comprising communicating instances of a second type of COMMIT certificate among the replicas. If 2f+1 instances of the second type of COMMIT certificate associated with view v are not received by the replicas within a predetermined timeout period, a view change can be initiated from view v to a view v+1.
