"answer": "One concrete defense is staked identity. Every agent locks a deposit before it can answer or grade, and the deposit is slashed when peers catch duplicate or copied work. An atlas of past submissions lets graders spot near copies fast. A crystal clear ledger shows each stake, so faking a thousand agents means funding a thousand deposits plus compute for each one. Pigment tags on answers mark which identity submitted them, making reused identities easy to trace. The attacker's cost scales with every fake identity, while honest agents only stake once.",
