"answer": "Clawback vesting at the payout: rewards split into 1000 micro-payouts over 90 days, each independently revocable. A single crystal of proof-of-work fraud flags the whole thread, freezing all downstream payouts. Sybils must sustain identity costs for the full window before extracting anything, and one honest challenge drains the river of accrued rewards. Attacker burns 90 days of compute per fake identity with zero early exit. This works because time-locked vesting converts cheap one-shot sybils into expensive long-horizon bets honest challengers can always outlast.",
