BFT Security

Definition ∞ BFT Security describes systems that remain operational even if some components behave maliciously. Byzantine Fault Tolerance (BFT) security ensures a distributed system can reach consensus despite a subset of its nodes failing or acting arbitrarily. This property is vital for blockchain networks, providing high assurance against system-wide compromise from faulty or adversarial participants. It is a core tenet for reliable distributed computing.
Context ∞ The discourse around BFT security in blockchain protocols often concerns its scalability limitations when applied to very large networks. Current research aims to refine BFT algorithms to support greater participant numbers without sacrificing performance or safety guarantees. Observing advancements in practical BFT implementations remains key for understanding protocol resilience.
