Fast and adaptive BFT state machine replication
Christian Berger · 2022
Recently, Byzantine fault-tolerant (BFT) state machine replication (SMR) experiences renewed research interest with the rise of novel BFT SMR-based distributed ledger technologies (DLTs). In DLTs, BFT SMR is used as a core primitive for maintaining a consistent append-only log by committing blocks of transactions in all replicas. In comparison with Proof-of-Work, BFT can typically improve performance and energy efficiency and comes with proven system properties.
