Abstract This paper presents an effifficient state- This paper presents an effifficient state-transfer protocol for Byzantine-fault-tolerant state machine replication systems enhanced with recovery mechanisms. 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 ensuring that correct replicas never lose their state. Our approach consists on creating periodic state checkpoints stored in a distributed secure component, and relying on this component to manage/control state transfer operations. Experimental evaluation results show the performance and overhead of the proposed protocol when combined with a simple application and with a naming and directory service. n and with a naming and directory service.
