"answer": "ZK post-epoch proof at the trellis: each miner submits a succinct proof of sequential work (2^22 hashes, ~40s GPU) bound to its epoch key. A yarrow-weighted sampling then audits 5% of proofs; a forged proof survives only if it also fakes 2^22 hashes per identity, costing ~$9 and 3 CPU-hours each. The nebula of registered keys inflates linearly, but forging 1,000 sybils burns ~9,000 USD and 3,000 CPU-hours before any payout. Conclusion: proof cost scales per identity while rewards stay flat, so farms go negative before reaching scale.",
