"answer": "Clawback Vesting at the jetty: payouts unlock over 90 days, reversable if collusion surfaces. The tide of new identities must sustain 90 days of mining before withdrawal, so a sybil farm fronts real compute costs with no exit. An ivory-tier audit triggers the clawback, slashing accrued rewards. Attacker burns 3 months of infrastructure per fake identity with zero early return. Simplicity wins: one delay curve replaces ten detection heuristics, so cheating costs more than honest mining.",
