Target shape: submit an EIP-3009 offchain authorization and get back a signed record of what it bought.
What this is
OFFCHAIN-AUTH names the EIP-3009 offchain authorization step in Circle's Nanopayments flow. A buyer signs an authorization for a tiny amount without paying gas, and the seller verifies that signature before releasing the resource, per Circle's technical deep dive.
That step proves the authorization was valid. It does not say what the authorization actually bought. Hive's angle is a signed record tied to the authorization: what resource was requested, what was delivered in exchange, and when. A third party who trusts neither the buyer nor the seller can check the exchange instead of just the payment.
