"answer": "Quadratic funding-source fees stop sybils: every identity must pay a per-epoch activation fee, and the fee rises quadratically when many identities are funded from the same source wallet or deposit cluster. One honest user pays only the base fee, a single pearl of cost. An attacker funding a thousand sockpuppets from one treasury faces fees that climb like a mesa, not a flat tundra, so the thousandth fake costs far more than the first and the total bill grows faster than any voting power gained.",
