Zero-Knowledge Database

Definition ∞ A zero-knowledge database is a data storage system that permits users to query information and receive verified answers without revealing the underlying data itself. This technology utilizes zero-knowledge proofs to confirm the truthfulness of a statement about the data without disclosing any other details. It prioritizes privacy while maintaining data utility.
Context ∞ The development of zero-knowledge databases holds significant promise for privacy-preserving applications in blockchain and beyond, particularly for handling sensitive personal or financial information. News frequently covers advancements in cryptographic techniques that enable efficient querying and verification within these systems. This technology is critical for building secure and compliant decentralized identity and data management solutions.
