A » The Fiat–Shamir heuristic is a cryptographic technique used to transform interactive proof systems into non-interactive ones, enhancing efficiency and practicality. Originally designed for zero-knowledge proofs, it allows a prover to convince a verifier of a statement's truth without revealing any additional information. Widely applied in blockchain technology, this heuristic improves protocol privacy and security by enabling compact, verifiable transactions without the need for real-time interactions.
