Formal Verification

Formal verification is a rigorous mathematical process used to prove that a smart contract or software program behaves exactly as intended under all possible conditions. Unlike regular testing (which checks specific scenarios), formal verification uses mathematical proofs to guarantee correctness. In blockchain, it is particularly important for high-value DeFi protocols and critical infrastructure where bugs can result in the loss of millions. While extremely thorough, formal verification is time-consuming and expensive, so it is typically reserved for the most critical code.
