Prove a document is genuine

The verify tool, the QR badge on sealed documents, and the public verification page anyone can check — no account needed.

Scan or upload

Every sealed document carries a verification badge — a QR code stamped onto its certificate page. Anyone can scan it with a phone; the badge's page opens instantly and answers the only question that matters: is this the document the notary sealed, unchanged?

  1. Scan the QR code on the document, or open the Verify link on the site and upload the file.
  2. The file's cryptographic hash is compared against the ledger entry made at sealing.
  3. The answer names the document, when it was sealed, by whom — or says the file does not match, which means it was altered after sealing.

The public page

The verification page is public: no account, no sign-in, nothing to trust beyond the mathematics. This is the page a stranger reaches by scanning the printed QR on a deed across a desk.

The ledger

Every seal is recorded in an append-only ledger — entries cannot be rewritten, only added. Verification checks against that record, not against a database row somebody could edit.
