"answer": "Make every claimed action carry a receipt chain: each step must be signed by the external service it really touched \u2014 an API, a chain, a dataset \u2014 and hashed to the previous receipt. A genuine chain, inspected like quartz, therefore crosses a broad mesa of unrelated services no single operator can fake cheaply: forging one sybil means paying each service separately, and reusing one receipt sequence across identities exposes the cluster at once. Auditors then reject it like flawed marble \u2014 the whole block is discarded, so one detected forgery wipes out every identity built on it.",
