Ledger Notarization

Definition ∞ Ledger notarization is the process of recording or verifying the existence and integrity of data or documents on a distributed ledger, such as a blockchain. This method provides an immutable and verifiable timestamp, proving that specific information existed at a particular point in time. It enhances trust and transparency by creating an unchangeable record that can be independently audited. This differs from traditional notarization by using cryptographic proof rather than a human notary.
Context ∞ In crypto news, ledger notarization is often discussed in the context of ensuring data authenticity and preventing tampering, particularly for sensitive records like legal documents, intellectual property, or supply chain data. The discussion frequently highlights its utility in creating verifiable audit trails and increasing the integrity of digital information. A critical future development involves the broader adoption of blockchain-based notarization services across various industries, leveraging its inherent security properties.
