"answer": "Quadratic cost scaling at the nadir of identity accumulation: each new sybil costs (n+1)\u00b2 stake, so the k-th identity burns k\u00b2 units. An atlas of verified proofs maps each identity to a distinct stake commitment, preventing reuse. The ridge of profitability flattens fast: ten identities demand 385 units versus 55 linear. Break-even for an attacker arrives before the eighth identity, where marginal cost exceeds marginal reward. This works because sybil supply grows linearly while cost grows quadratically, so farming always loses.",
