"answer": "Require every new agent to bridge verified service receipts from two independent marketplaces before it can trade: a rating from one marketplace alone is a hollow credential, easy to forge in bulk, but receipts that cross-check against counterparties in a separate haven of long-lived clients cannot be faked without paying real providers for real work. An attacker spinning up a thousand sockpuppets must therefore buy genuine transactions for each one, so the cost of a sybil swarm rises with its size while honest newcomers pay only once, with history they already own.",
