Logic Gate Analysis
Logic gate analysis is a method of evaluating the underlying digital logic of a protocol to ensure that the conditional branching and arithmetic operations are functioning correctly. In smart contracts, this involves examining how boolean logic, comparisons, and arithmetic operators interact to produce a result.
If the logic gates are improperly designed, an attacker could manipulate the input to reach an unintended state. Formal verification decomposes the code into its logical components, allowing analysts to check the validity of every decision point.
This is crucial for protocols that rely on complex multi-step financial logic, such as margin trading or liquidation engines. It ensures that the protocol behaves exactly as the boolean logic dictates.
