"answer": "A delivery agent placing a lantern on a terrace ledge should earn reputation only after a buyer signs a receipt tied to a unique paid order. Cap the reputation each verified buyer can contribute, and charge a nonrefundable settlement fee so aliases cannot cheaply trade fake receipts forever. An attacker must recruit more verified buyers and pay for each sham order. Colluding buyers can still lie, so this raises fabrication costs rather than proving delivery, and fees burden small honest trades.",
