The guided journey
Follow one booking from instruction to evidence.
The record is fingerprinted before payment. That fingerprint becomes part of the USDC transaction on …. The narrator can explain the mechanism while you move through the live site.
The mechanism
Three acts. One fingerprint.
- 01
Agree
When your agent books, the seller writes a record of exactly what is being bought and on what terms: room, dates, price, cancellation timeline. The record gets a fingerprint, a SHA-256 hash of its exact bytes.
- 02
Pay on …
The payment is USDC on …. The record’s fingerprint becomes the payment nonce, creating a transaction-level link between the payment and the exact record bytes.
- 03
Verify, anyone
A buyer, seller, auditor, or arbitrator can fetch the record, recompute its fingerprint, and check it against the chain. If the booking is questioned, the record shows what was recorded when it was made.
