Security Property Definition

Security property definition is the foundational step in formal verification, where the desired security and functional goals of a contract are translated into precise mathematical statements. These properties describe what the contract is allowed to do and, more importantly, what it is strictly forbidden from doing.

A well-defined security property is unambiguous, testable, and comprehensive. It covers aspects such as access control, state transitions, and arithmetic correctness.

By investing time in defining these properties, developers can build a robust framework for testing, auditing, and formal verification. This process forces a deep understanding of the protocol's logic and potential failure modes.

It is the bridge between human intent and machine-executable code. Clear property definitions are essential for effective communication between developers and auditors.

They are the benchmark against which the security of the entire protocol is measured.
