Formal Verification Constraints

Formal verification is a mathematical approach to proving the correctness of smart contract code against a defined specification. It uses logic and theorem provers to ensure the code behaves exactly as intended under all possible inputs.

The constraint lies in the complexity and high cost of defining these specifications accurately. If the specification itself is flawed or incomplete, the proof may be mathematically correct but logically irrelevant to the actual security of the protocol.

Additionally, it is computationally expensive and difficult to apply to highly dynamic or rapidly changing codebases.
