The registry only ever grows. Nothing is edited, nothing is back-dated, and you do not have to take our word for it. Once a day we publish a digest that commits to every gift ever signed, and each digest is chained to the one before it.

Check it yourself

Here is the exact recipe, so you can recompute any digest without us.

  1. Build one line per entry: the gift id, the serial number and the signature, joined by the unit separator byte 0x1F.
  2. Start with the previous digest (an empty string for the very first checkpoint), add a newline, then add every line in chain order, each one newline terminated.
  3. Take the SHA-256 of those bytes as UTF-8. The lowercase hex digest is the checkpoint.
  4. To reproduce an older checkpoint, use only the first N entries, where N is that checkpoint's gift count. The chain order only ever grows, so that prefix is exactly what the digest was cut over.

Chain order is the moment of signing, then the gift id. A gift enters the chain when it is signed and never moves again.

Every gift that was ever signed takes part, whatever its status is now. A revoked or withdrawn certificate keeps contributing its id, serial and signature, so closing an account can never rewrite history.

A checkpoint carries no personal data. It commits to gift ids, serial numbers and signatures, all of which are already public.
