Blockchain notarization provides a secure method to verify the authenticity of documents by timestamping and recording them on a blockchain. Once notarized, records cannot be altered or deleted, ensuring integrity and legal validity. It’s used for contracts, academic certificates, legal documents, and intellectual property. This decentralized approach eliminates the need for third-party notaries, reducing costs and delays. By leveraging cryptographic hashing, blockchain notarization offers a transparent, immutable, and easily verifiable method to prove the existence and originality of a document.
