Definition ∞ A verifiable database is a database system where the integrity and authenticity of stored data can be cryptographically proven to any observer, without requiring trust in a central authority. Each entry or modification is typically accompanied by a cryptographic proof, such as a Merkle proof, allowing independent verification. This ensures data immutability and resistance to tampering. It provides a high degree of transparency and auditability.
Context ∞ News often discusses verifiable databases in the context of blockchain technology, where the distributed ledger itself functions as a form of verifiable database. Developments in zero-knowledge proofs and other cryptographic techniques are enhancing the verifiability of off-chain data. This concept is central to building trustless systems and improving data transparency in various applications.
