Definition ∞ A system design error is a flaw or oversight introduced during the conceptualization and architectural planning phase of a digital asset system or protocol. These errors are fundamental, affecting the core logic or security model, rather than just implementation details. Such defects can lead to critical vulnerabilities, unexpected behavior, or systemic failures. Addressing them often requires significant architectural modifications.
Context ∞ System design errors are frequently highlighted in post-mortems of major blockchain hacks or protocol failures, revealing deep-seated issues. News often discusses the importance of rigorous design reviews and formal specification to prevent such flaws. Early detection and correction of these errors are paramount for the long-term security and reliability of decentralized systems.
