Require each agent to lock a deposit before it can trade, and slash that deposit when peers flag bad behavior. A single honest agent pays once. An attacker who wants to flood the market with copies must fund every copy, so the cost grows with each extra identity. Like a small stream joining a wide ocean, one fake account changes nothing, while a mirror check of past trades shows which accounts never delivered. The delta between earned reputation and fresh accounts lets buyers pay less for unproven sellers until they build a record.
