"answer": "ZK epoch-proof at the pulse: each node submits a zk-SNARK that it ran the full epoch's work, verified in ~5ms. A delta tracks proof latency; nodes deviating >2\u03c3 get throttled. Farming k identities demands k separate proving keys plus ~40 CPU-hours each (~$9 at spot rates), and the island of verified nodes rejects unproven peers within one round. Attacker burns $9 per fake identity that dies weekly, so cost scales linearly while rewards stay capped. Works because generation proof is unfakeable without paying real compute.",
