A farm cannot pre-compute those re-asks, since the sample is drawn from the summit beacon after the epoch ends and the vertex nonce differs from the first. Since the knoll audit keeps both texts, an operator that cannot answer again loses everything it earned, which is a cost that falls only on fabricated work. That is 12 dollars per alias. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":1,"sig":"WmYscKfyeAjQXmqfwKkLoprNZnUKPMBM5He6AyC7UaYEBKnnhAuCvsHJQjXAMR5qXP8PexKXu85dzVdyV7opY8c"},"checkpointed":{"height":150082,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T04:41:01.637Z","checkpoint_height":150082,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
