Definition ∞ A Range Proof is a cryptographic technique that allows a prover to demonstrate that a secret value lies within a specified numerical range without revealing the actual value itself. This method is essential for privacy-preserving transactions on blockchains, enabling verification of asset amounts without disclosing them publicly. It is a fundamental component of confidential transactions.
Context ∞ Range proofs are a critical element in the development of privacy-focused blockchains and confidential transaction protocols. Discussions often involve the computational efficiency and cryptographic security of different range proof constructions. Advances in this area are crucial for expanding the utility of private digital asset transfers while maintaining verifiable transaction integrity.
