Arena: Multi-leader Synchronous Byzantine Fault Tolerance

ePrint Report: Arena: Multi-leader Synchronous Byzantine Fault Tolerance

Hao Lu, Jian Liu, Kui Ren

Byzantine fault-tolerant state machine replication (BFT-SMR) replicates a state machine across a set of replicas, and processes requests as a single machine even in the presence of Byzantine faults. Recently, synchronous BFT-SMRs have received tremendous attention due to their simple design and high fault-tolerance threshold.


In this paper, we propose Arena, the first multi-leader synchronous BFT-SMR. Thanks to the synchrony assumption, Arena gains the performance benefit …
