Byzantine Attack Resistance

Definition ∞ Byzantine attack resistance describes a distributed system’s capacity to continue operating correctly despite the presence of malicious or faulty components. This property ensures the network maintains its integrity even if a portion of its participants behaves dishonestly. It is a critical measure of a blockchain’s robustness and security.
Context ∞ The concept of Byzantine attack resistance is central to the security models of various blockchain protocols. News often highlights advancements in consensus algorithms that enhance this resistance, such as those used in proof-of-stake systems. Debates frequently involve the threshold of malicious actors a network can tolerate while preserving data validity and transaction finality.
