What this record proves

  • This content was registered with Sellat on this date.
  • The content shown has not been modified since it was registered.
  • If there are several versions, their order within this history can be checked.

It does not prove that the price is correct, nor that the store did not publish other prices outside this history.

Your browser downloads the records and the texts, recomputes their fingerprints and checks that each record points to the previous one. It does not rely on what this page says.

Technical details and verification

Everything needed to check it without trusting this page or Sellat: fingerprints, chaining, Polygon transactions and downloads.

Checked when this page loaded: every record points to the previous record’s fingerprint, every text has the fingerprint its record states, and every record is anchored on Polygon. The sequence is intact in itself; it cannot rule out versions the author did not register.

Manual verification

You do not need to trust this page or Sellat. Download the text, its record and its proof, and compute the fingerprints with any standard tool:

shasum -a 256 historial-S9oTXKzIu0m5KZ88X26LHg-v1.txt
shasum -a 256 historial-S9oTXKzIu0m5KZ88X26LHg-v1.record.json
npx sellat-verify historial-S9oTXKzIu0m5KZ88X26LHg-v1.record.json proof.json

The first fingerprint must appear as evidence.sha256 inside the record; the second as content.hash inside the proof. The verifier recomputes the Merkle path and asks Polygon.

Or drop any file here: the fingerprint is computed in your browser and the file never leaves your computer.

What it proves and what it does not

  • Proves that each exact text existed by the date of its Polygon anchor and has not changed since.
  • Proves the order in which the shown versions were registered and that none has been replaced.
  • Does not prove that what the text says is true.
  • Does not prove on its own who wrote it: authorship is what the record says and the account that made it, not certified by a third party.
  • Does not guarantee that there are no versions the author did not register, nor parallel histories: the sequence is intact in itself.
