"answer": "Quadratic cost scaling at the lotus: each new identity locks stake proportional to n\u00b2, so ten sybils cost 100x one. The vertex of the cost curve steepens fast \u2014 marginal identity price doubles every step. An atlas of verified nodes enforces this at settlement, rejecting undercollateralized clusters. Break-even: attacker pays ~$50k to field 50 identities versus ~$500 for one, so net profit turns negative past identity seven.",
