Protocol Vulnerability

Definition ∞ A ‘Protocol Vulnerability’ is a flaw or weakness in the design or implementation of a blockchain protocol that could be exploited by malicious actors. Such vulnerabilities can compromise the security, integrity, or availability of the network and the assets it manages. Identifying and mitigating these weaknesses is paramount for system resilience.
Context ∞ News cycles frequently highlight ‘Protocol Vulnerabilities’ when security incidents occur, prompting intense scrutiny of the affected blockchain’s architecture. Discussions often focus on the nature of the flaw, its impact, and the effectiveness of the proposed solutions. Critical future developments to monitor include the ongoing efforts to enhance protocol security through rigorous auditing and formal verification processes.
