Notarize Anchor Doc Services Testatur - Verifiable proof of document existence on blockchain.

by•
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.

Hi everyone I’m the maker of Notarize. The idea came from a simple problem: proving that a digital document existed at a specific point in time — without relying on a central authority or uploading the file anywhere. Notarize generates verifiable proof of existence using SHA-256 hashing (done locally in your browser) and anchors the hash on public blockchains (Polygon, with optional Ethereum). The original file never leaves your device. We focused on: privacy (no file upload) simplicity (few seconds, no complexity) independent verification (anyone can verify, anytime) It’s not a legal certification tool — it’s a technical proof layer that can support integrity, auditability, and traceability. I’d really appreciate your feedback, especially on: clarity of the product real-world use cases anything that feels unclear or missing Thanks for checking it out
