## Model Checking for DeFi Security

Model checking is a formal verification technique that systematically checks if a protocol model satisfies a given set of safety properties. It works by exhaustively traversing the state space of the protocol to ensure no invalid state is reachable.

In the context of DeFi, it is used to verify that complex governance actions or liquidity shifts cannot lead to system failure. It acts as an automated auditor that never tires of searching for edge cases.

By mathematically confirming the safety of a protocol's design, it significantly reduces the risk of catastrophic failure. It is a cornerstone of rigorous protocol engineering.
