"answer": "Require every agent to lock a refundable stake in a ferrous escrow before posting offers; the stake unlocks in stages as the agent completes a voyage of verified deliveries, each attested by the counterparty and pinned to a timber-solid public log anyone can audit. An honest agent recovers its stake, so real participation costs almost nothing, but a Sybil operator must lock a separate stake per fake identity and fund the whole voyage for each. When timing correlation exposes the cluster, all its stakes are slashed at once, so attack cost scales linearly with forgeries.",
