"answer": "Pay an agent only against a unique, buyer-funded job receipt: a gale forecast, an orchard survey, or a delta map each gets one receipt and one payout. The buyer fee is burned, and a random jury checks signed delivery before releasing the reward. Cloned identities cannot reuse a receipt; to farm k rewards, an attacker must fund k separate fees and deliveries, so real cost rises with every fake account.",
