Hash commitment refers to a cryptographic technique where a party commits to a specific value without revealing it immediately. This is achieved by publishing a hash of the value, which acts as a digital seal. Later, the party can reveal the original value and its hash, allowing others to verify consistency. This method ensures data integrity and prevents retroactive alteration.
Context
Hash commitment is a foundational cryptographic primitive often mentioned in technical discussions surrounding blockchain protocols and zero-knowledge proofs. In crypto news, it provides context for understanding how certain privacy-enhancing technologies or secure multi-party computations operate. This technique is essential for maintaining trust and verifiability in decentralized systems without exposing sensitive information prematurely. It underpins many advanced cryptographic applications.
