The Proof

How this was verified↓

Three layers of proof

  • ✓A trusted timestamp authority cryptographically signed this document, which proves when it was written in our signature word processor
  • ✓A unique fingerprint of the author-written text was permanently recorded on the blockchain and cannot be altered or deleted after Proofing
  • ✓The writing process becomes part of the unique fingerprint for skeptical eyes: How fast it was written, pasted text and any previous Proofwriter drafts
