Notarize Anchor Doc Services Testatur
Verifiable proof of document existence on blockchain.
What it does
Notarize lets you generate verifiable proof of a document’s existence using public blockchains. Files are never uploaded: hashing happens client-side (SHA-256), and only the hash is anchored on Polygon, with optional Ethereum anchoring. Each notarization includes a verifiable certificate. Built for integrity, privacy, and independent verification.
