Verifiable Databases

Definition ∞ Verifiable databases are data storage systems where the integrity and authenticity of stored information can be cryptographically proven. These databases employ cryptographic commitments, such as Merkle trees or authenticated data structures, to allow any observer to confirm that data has not been tampered with or incorrectly reported. This capability is crucial for decentralized applications and supply chain solutions where trust in data integrity is paramount. Verifiable databases enhance transparency and auditability in data management.
Context ∞ Verifiable databases are gaining prominence in blockchain-adjacent technologies and decentralized data storage solutions, addressing the need for provable data integrity. The discussion often revolves around the trade-offs between verifiability, storage efficiency, and query performance. Future applications will likely extend to decentralized identity systems and secure data sharing platforms.
