Active quorum systems
Alysson Bessani, Paulo Sousa, Miguel Pupo Correia · 2010
This paper outlines a flexible suite of object replication protocols that brings together Byzantine quorum systems registers and state machine replication. These protocols enable the implementation of Byzantine fault-tolerant applications that make minimal assumptions about the environment and that run in at most two more communication steps in almost all cases of non-favorable executions (in comparison with favorable executions). 1
