Formal Proof

Definition

A formal proof is a rigorous, logically sound demonstration of a statement’s truth, constructed using defined rules. In computer science and blockchain, this refers to a mathematical argument that a system, algorithm, or smart contract behaves precisely according to its specifications. These proofs are generated through formal verification methods, providing a very high degree of certainty about correctness and security properties. They are crucial for systems where errors could lead to significant financial loss or security breaches.
