BFT Scalability

Definition

BFT scalability refers to the capacity of a Byzantine Fault Tolerant consensus protocol to maintain performance as the number of participating nodes increases. BFT protocols are designed to function correctly even if some network participants act maliciously. Scalability in this context measures how well the protocol’s throughput and latency hold up under a growing number of validators without degrading security. It is a key metric for enterprise and permissioned blockchain networks.
