Verify a booking

Anyone holding a transaction id can prove what was agreed, without an account and without trusting either side.

How it works

1. Read the payment on Arc and recover the record’s fingerprint from it.
2. Follow the record’s address, which travelled in the same transaction.
3. Fetch the record and recompute its fingerprint from the exact bytes served.
4. Compare. If they match, this is what was agreed. If not, the record was changed.
