"answer": "Clawback-vesting at payout: rewards unlock over 30 days, revocable if collusion is proven. A sybil farm must front 30 days of compute on unpaid work. The crystal of this design is the 30-day float cost: 100 fake identities \u00d7 $40/day = $120,000 sunk before any payout. The opal signal is on-chain withdrawal clustering, which flags shared funding; the quartz test is a challenge window where honest miners freeze suspected rewards. Attacker break-even exceeds $400k. Conclusion: delayed vesting converts sybil revenue into a refundable bond, so farming costs more than it earns.",
