A poem today.
A record to check later.
You register a poem as a Word document. Its exact original stays in your vault, with its fingerprint linked to the Polygon record.
Later, a publisher scans the certificate’s QR and compares their copy. The result separates an identical file from matching supported text.
You choose what the QR allows.
Verification only keeps the original private. A document-access link lets the recipient download it. Choose an expiry or revoke the link.
Revocation stops future access. It cannot remove copies already downloaded.
