Which blockchain is used for anchoring?

Document hashes are anchored on the Hedera Consensus Service (HCS mainnet Topic 0.0.10373605) via NotaryChain, providing permanent, millisecond-timestamped cryptographic receipts verifiable via HashScan or any Hedera Mirror Node.

Can the blockchain proof be verified by anyone?

Yes. Any third party can verify the notarization by checking the document hash against the blockchain record. The verification is cryptographic and does not require trusting any central authority.

Does Web3 notarization replace traditional notarization?

Web3 crypto notarization adds an additional layer of cryptographic proof on top of traditional notarization. It is especially valuable for digital assets, cross-border agreements, and situations where permanent, verifiable proof is required.

Web3 Crypto Notary — Blockchain-anchored notarization. Web3 crypto notarization via NotaryChain anchors a cryptographic hash of your document directly on the Hedera Consensus Service mainnet (Topic 0.0.10373605), 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 via HashScan. Unlike traditional notarization, the proof is permanent and cannot be altered — providing cryptographic certainty that lasts as long as the blockchain exists. Available nationwide starting at $75 per notarization + anchoring. Book a consultation with Clay Murphy, Florida-commissioned Web3 Crypto Notary.

Key Benefits

Document Hash on Chain

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.

Cryptographic Proof

The notarization generates cryptographic proof that can be independently verified by anyone, anywhere, without relying on a central authority.

Immutable Timestamp Record

The blockchain timestamp is permanent and tamper-proof, providing legal evidence of when the document was notarized.

Smart Contract Attestation

A smart contract attestation provides programmatic verification — third parties can verify the notarization automatically through the blockchain.
