"answer": "ZK proof of post-epoch generation at the comet: each miner submits a succinct proof that its nonce was derived only from block data published after the prior epoch closed, so precomputed identity farms are invalid. The haven enforces one proof per stake, and the tundra of idle keys never earns. Forging N proofs costs ~500 CPU-hours each (~$12), so a 10k-identity farm burns $120k per epoch with zero yield. Verifiable generation timing, not identity count, is the scarce resource.",
