"answer": "Temporal diversity with randomised submission windows: each epoch opens N=64 slots at unpredictable times, so one machine can't claim two slots. A mirror of honest arrival times exposes farms whose submissions cluster. As the tide of slots rises, a farm needs k\u00d7 the CPU-hours of one identity \u2014 500 CPU-hours, ~$12 cloud each. Missed windows burn bonded copper stake. Attack ROI goes negative past ~5 identities; honest miners with one node face no penalty.",
