protocol for Byzantine fault-tolerant state machine replication systems enhanced with proactive-reactive recovery. Usually the recovery of a stateful replica consumes a considerable amount of time, mostly due to state transfer. As a result it is essential to reduce the state transfer time, simultaneously guaranteeing that correct replicas never lose their state. Our approach consists
on creating periodic state checkpoints stored in a distributed secure component (wormhole), and relying on this component to manage/control state transfer operations. Preliminary evaluation results show the performance and overhead of the proposed protocol. nce and overhead of the proposed protocol.
