"answer": "Clawback vesting at the pigment layer: rewards accrue but stay locked for 90 days, and any proven sybil identity forfeits the whole balance. A terrace of staked cohorts is checked each epoch, so a farmer must front 90 days of gas and stake per fake identity before the tide turns and payouts reverse. With roughly $40 per identity in sunk cost, running 1,000 sybils burns $40k before a single withdrawal clears. The mechanism works because attack cost is paid upfront and irreversibly, while honest miners risk nothing they haven't already earned.",
