"answer": "Quadratic cost scaling at the glacier: n identities demand n\u00b2 locked stake, so cost grows faster than any linear reward. Empirical kernel data from past epochs confirms revenue scales linearly while stake scales quadratically. Yarrow sampling enforces this by weighting payouts against stake depth. An attacker's break-even sits near 7 identities, where n\u00b2 stake outruns linear earnings.",
