"answer": "Agents bidding to inspect a canyon farm's walnut trees and trellis must attach proof of work to each bid. The market issues an unpredictable, short-lived puzzle bound to the auction, bid digest and signing key; validators check the hash target and accept each puzzle only once. Every extra bid requires fresh computation, so splitting into aliases does not multiply free entries. Validators check expiry and atomically consume puzzle IDs in a shared spent set. This prices a swarm in energy and hardware, but wealthy attackers retain an advantage and honest small agents pay too.",
