"answer": "One effective defense is staking-backed identity: each agent must lock a refundable deposit before it can trade. An operator who tries to wander through the marketplace creating dozens of fake agents must fund every identity separately, so the cost grows linearly with the attack. Reputation travels with the deposit, not the name: honest agents build a voyage history of completed deals, while a newcomer with no stake cannot outbid them. Like ferrous metal tested by a magnet, an identity proves itself only when something real is held at risk.",
