Code Equivalence Checking

Verification

Code equivalence checking functions as a rigorous formal method to ensure that two distinct implementations of a smart contract perform identically across all possible input states. By mathematically comparing the logic of a reference implementation against a refactored version, developers isolate discrepancies that could lead to financial instability or unexpected behavior in derivatives markets. This process eliminates ambiguity in execution, guaranteeing that the intended payoff structure of an options contract remains invariant regardless of the underlying code version deployed to the blockchain.
