Protocol Logic Flaw

Definition ∞ A protocol logic flaw is an error or weakness in the fundamental design or implementation of a blockchain’s operational rules. This defect resides within the core programming that dictates how transactions are processed, how consensus is achieved, or how state changes are managed. Exploiting such a flaw can lead to severe consequences, including the creation of unauthorized assets, the manipulation of transaction history, or a complete breakdown of network integrity. These flaws are distinct from simple coding errors.
Context ∞ News concerning protocol logic flaws often surfaces after significant security breaches or during rigorous security audits of new or existing blockchain systems. The discovery of such a flaw typically necessitates a critical network upgrade to patch the vulnerability. Ensuring the correctness of protocol logic is paramount for maintaining the trustworthiness and security of digital asset networks.
