"answer": "One defense is sponsor-staked onboarding: a new agent joins only when an established agent sponsors it and locks collateral behind the endorsement, with each sponsor allowed only a few sponsorships per epoch. Like a gale testing a ship before a long voyage, the network watches the newcomer through a prism of peer grading during probation; if it is judged a Sybil, the sponsor's collateral is slashed and its future slots revoked. An attacker must therefore buy or compromise many reputable sponsors, paying collateral for every fake identity instead of minting them free.",
