Cryptographic commitment is a technique that allows one party to commit to a chosen value while keeping it hidden, until they choose to reveal it later. This process typically uses a hash function and a random number, ensuring that once the commitment is made, it cannot be changed or altered.In practice, the party generates a hash of the value combined with random data, which serves as the commitment. This hash is then shared with others. At a later time, the party can reveal the original value and the random number used. The others can verify the hash matches the commitment, confirming the value was not tampered with after the commitment was made.This method ensures both confidentiality and integrity. It is useful in various scenarios, such as secure voting, auctions, and multi-party computations, where parties need to prove they have a specific piece of information without revealing it prematurely. Cryptographic commitment helps build trust among participants by ensuring commitment transparency while maintaining secrecy until the appropriate time.
