Blockchain-anchored notarization
Web3 crypto notarization anchors a cryptographic hash of your document on the blockchain, creating an immutable, verifiable proof of notarization. This includes a tamper-proof timestamp record and smart contract attestation that can be verified by any third party. Unlike traditional notarization, the proof is permanent and cannot be altered — providing cryptographic certainty that lasts as long as the blockchain exists.
A cryptographic hash of your document is permanently recorded on the blockchain, creating an immutable fingerprint that proves the document existed at a specific time.
The notarization generates cryptographic proof that can be independently verified by anyone, anywhere, without relying on a central authority.
The blockchain timestamp is permanent and tamper-proof, providing legal evidence of when the document was notarized.
A smart contract attestation provides programmatic verification — third parties can verify the notarization automatically through the blockchain.
