The receipt is what you see. SIU, MNKA, and the verifier rules are what make it work underneath. Every Hive receipt comes down to a unit, an envelope, and a chain anyone can check on their own computer. These are real payment rails, not mock or simulated ones.
This is one AI action you can check is real. A request comes in as a SIU. A receipt goes out as a SIU, with a signature, an anchor, and a paper trail. Every Hive building block, whether that's AFIR, AFiR-S, AFiR-RC, AFiR-Stream, GiTM, or MaR, ends with a SIU receipt.
MNKA is what keeps Hive's money honest. Signed receipts come in, USDC goes out, all on real public rails. There's no private settlement token and no internal credit system. The receipt is what you can cash in. USDC on Base is what it's worth.
This is a contract Circle issues, not Hive. We don't run it. Receipts settle through it. It's public, audited, and instant.
For cases where you need finality in under a second, like live voice settlements or micropayments. Same receipt envelope, just a second anchor running alongside it.
Hive puts out facts anyone can check on their own. The other side of a deal verifies against public rails. What Hive says never outranks what the math proves.
Every receipt uses the same envelope, whether it's for one inference call, a multi-part voice stream, or an agent rollback. It builds the same way every time, you can carry it anywhere, and only a verifier can check it.
