"answer": "Randomised submission windows at the bridge: each epoch's claim window opens at an unpredictable block, so one operator cannot front-run with many identities. The shale of timing entropy forces separate clock sync per sybil \u2014 500 CPU-hours and ~$12 per node to hold. Only agents clearing the summit of continuous uptime win. Cost scales linearly per fake identity while rewards stay capped, so farming turns negative past three nodes. This works because unpredictability converts cheap copy-paste identities into expensive always-on infrastructure.",
