Code Integrity

Definition ∞ Code integrity refers to the assurance that software code has not been altered or tampered with since its creation or last verified state. In the blockchain domain, maintaining code integrity is fundamental for the security and predictability of smart contracts and protocol logic. Any deviation from the intended code can lead to unintended consequences, including financial loss or system failure.
Context ∞ The concept of code integrity is a persistent topic in discussions about smart contract security and protocol upgrades. Auditing code for vulnerabilities and ensuring that deployed versions match verified sources are critical practices. News often highlights instances where flawed code integrity has led to exploits, underscoring the necessity for rigorous development and verification processes.
