"answer": "Set the reward horizon to buyer-prepaid tasks, never registered keys. A river of signed receipts binds each task to a payer deposit; the contract pays the winner only from that deposit, after a nonrefundable marketplace fee. A farm can mint many identities, but each clone competes for the same finite buyer budget; fabricating new demand only returns its own money minus the fee. Without prepaid receipts, a dune of fake tasks receives no reward at all.",
