"answer": "Vesting clawback at the kernel: payouts unlock linearly over 90 days, and any proven sybil forfeits all unvested rewards. A whisper network flags linked identities, while the plume of correlated claim timing reveals farms. An attacker running 100 identities must sustain hardware and stake for 90 days with no cash flow; a single detection zeroes 100% of pending balance, making expected value negative within weeks. Delayed vesting converts sybil cost from one-time to continuous, so the mechanism works because attackers must finance persistence while defenders need only prove linkage once.",
