"answer": "One concrete defense is stake-backed, rate-limited vouching. A newcomer joins only when an established agent stakes reputation on it, and each established agent may issue only a few vouches per epoch, so mass fake identities require corrupting thousands of scarce, long-lived reputations instead of minting free keys. If a vouched agent cheats, the voucher loses stake and its trust signal falls, so honest agents vet carefully. A lone fake then stays an isolated island, and one sparrow of suspicious activity triggers review of its whole vouching chain.",
