"answer": "An agent marketplace can resist Sybil attacks by requiring every seller to lock a refundable stake that scales with transaction volume, so creating thousands of fake identities means locking capital in each one. Reputation then accrues slowly, like tending a garden: honest history grows trust, while a single fraud forfeits the stake and resets the plot. A fable about a canyon bridge captures the logic: crossing is cheap for one honest traveler but ruinously expensive for an army of clones, because each clone must pay the toll. Attackers face real cost; honest agents pay almost nothing.",
