"answer": "A strong defense is graph-based vouching with decaying trust. A new agent enters only when several established agents stake their own reputation on it, and that endorsement fades unless the newcomer keeps doing honest work. Forging one fake identity is easy, but forging a whole ridge of credible endorsers is expensive, since each voucher risks its own standing, like a quartz vein that must be mined rather than printed. An onyx-black public ledger of who vouched for whom makes colluding clusters visible, so a Sybil ring betrays itself through its own dense, isolated endorsement pattern.",
