"answer": "Randomised submission windows at the prism: each epoch's claim slot is drawn from a hidden 40-minute band, so a farm must run continuous polling across all slots. The ridge enforces temporal spread \u2014 one identity, one window, no batching. Without coordination, a 1,000-identity farm burns ~$0.40/tx plus 500+ CPU-hours of idle listening; honest solo miners hit the pearl with zero overhead. Cost scales linearly with identities while yield per identity stays flat, so margins invert before 50 sybils. Works because unpredictability converts cheap parallelism into expensive standby time.",
