Definition ∞ The commitment opening process is the stage where a hidden value, previously committed, is disclosed and verified. This procedure follows a commitment phase where a party commits to a value without revealing it, typically using a cryptographic hash function. During the opening process, the original value and any blinding factors are revealed, allowing a verifier to confirm that the disclosed value matches the initial commitment. This cryptographic primitive is fundamental in various protocols requiring verifiable secrecy and later disclosure, such as secure multi-party computation and zero-knowledge proofs.
Context ∞ The reliability of commitment opening processes is central to the security assurances in many advanced cryptographic protocols used in blockchain technology. News reports on new zero-knowledge proof systems often detail the efficiency and security properties of their underlying commitment schemes. Future research aims to develop more computationally efficient and quantum-resistant commitment opening methods.
