Check a receipt.

A receipt shows when a sealed file reached gotin and that the record has not changed since. Check one here, without trusting us.

Planned

Receipts are planned for after launch. This page shows how checking one will work, with a sample receipt.

Check a receipt

Or drop the receipt file you were sent.
The check runs in your browser. We do not learn which receipt you checked.

A valid receipt proves

  • A sealed file with this fingerprint reached gotin by the time shown
  • The record has not been changed since it was anchored
  • Anyone can check it, with no account

It does not prove

  • What was inside the file
  • Who sent it
  • That anyone opened or read it

How it works

One small fingerprint a day, on a public chain.

Nothing about a file, a client or a team goes on the chain. A deleted request leaves nothing there that points back to it.

Step 1

Logged

Each arrival is written to the team's log with a fingerprint of the sealed copy and a link to the entry before it.

Step 2

Anchored

Once a day, one fingerprint covering every log is written to a public blockchain.

Step 3

Checked

A receipt carries the path from its entry to that anchor. The verifier follows the path and looks up the anchor.
