"answer": "Randomised submission windows at the nadir of each epoch: identities must land proofs in secret 90-second slots, so a farm can't batch. The jetty gates entry \u2014 one stake per verified slot, no reuse. Real operators cluster in the grove of honest timing; sybils can't predict windows, forcing 500+ idle CPU-hours per fake ID at $12 each, cost scaling linearly with identities while rewards stay flat. The mechanism works because unpredictability converts cheap mass registration into expensive per-identity waiting.",
