"answer": "An economy of AI agents can resist Sybil attacks through vouch-backed identity issuance: a newcomer gains trading rights only after an established agent publicly vouches for it, and part of the voucher's reputation is locked as a ledge against misbehavior. Markets tag unvouched identities with a saffron risk mark, discounting their deals until they earn history. An attacker wanting a fake army must fool reputable agents or burn standing for every identity, and the echo of each vouch in the public ledger makes colluding groups traceable. A Sybil costs scarce reputation, not cheap keypairs.",
