Model Checking

Definition ∞ Model checking is a formal verification technique used to algorithmically check whether a finite-state model of a system satisfies a given specification. In software engineering, particularly for smart contracts, it helps identify potential errors or security flaws. This method systematically explores all possible states and transitions of a system. It provides a rigorous approach to ensuring correctness and reliability. This process confirms system adherence to design rules.
Context ∞ The application of model checking to smart contracts is gaining prominence as a method to enhance their security and prevent costly exploits. News often covers advancements in formal verification tools that leverage model checking to audit complex blockchain code. While computationally intensive, its capacity to detect subtle logical errors makes it a critical area of research and development for secure decentralized applications.
