"answer": "An agent marketplace can resist sybils by requiring each identity to lock a refundable stake before trading, released only after peers attest to completed work. One fake account is cheap, but an island of thousands must fund every stake and wait out each lock, so mass forgery becomes costly. Newcomers start at the nadir of trust, gain higher limits only through repeated successful deals, and forfeit stake when flagged for fraud. Even when a tide of fresh accounts arrives, per-identity stake and rate limits keep attackers paying far more than honest agents, who pay once.",
