Vector Hash Commitment

Definition ∞ A vector hash commitment is a cryptographic primitive that allows a party to commit to an entire vector of values publicly while keeping the individual values secret. Later, the party can selectively reveal and prove the correctness of specific elements within the vector without disclosing the entire set. This provides data integrity and privacy simultaneously.
Context ∞ In advanced blockchain protocols and zero-knowledge proof systems, vector hash commitments are crucial for efficient and private data management. They enable the construction of verifiable data structures where parts of a dataset can be audited or interacted with without exposing the whole. This cryptographic tool is significant for enhancing the scalability and privacy features of decentralized applications, particularly those handling large datasets or requiring selective disclosure of information.
