Signed receipts connect each job to its metered work.

Start with a signed job receipt

Each completed job emits a COSE receipt signed by its node key. The receipt links the job, node and metering record. In the sealed lane it also carries references to attestation evidence. The receipt proves execution on the measured stack; it does not prove the answer was correct.

Verify before metering earnings

The verifier checks the signature, job-to-billing match and measured token counts. Metering applies the posted rate card to verified work and records the resulting USDG amount in the earnings ledger. SPDL is used for access and stake, rather than as the unit of earnings.

Build an hourly cumulative root

The epoch builder creates a cumulative Merkle tree every hour and posts its root on Robinhood Chain. A leaf records the owner and cumulative earned amount. The shared claim accounting tracks amounts already consumed across wallet, stock and card routes.

Keep the proof with the claim

A claim uses the epoch, cumulative amount and Merkle proof. The design checks funding before accepting a root and uses a common claimed balance across payout routes. The website illustrates these steps without presenting live receipts, balances or completed claims.
