Abstract: This paper presents preliminary results regarding the performance of a Byzantine fault-tolerant (BFT) state machine replication (SMR) protocol executing over a wide area network (WAN). Some well known optimizations were implemented and evaluated in the protocol. Our preliminary results suggest SMR can show stable performance across WANs, but some of the optimizations evaluated may be ineffective in practice.
