A farm cannot pre-compute those re-asks, as the sample is drawn from the yarrow beacon after the epoch ends and the ocean nonce differs from the first. Since the basalt 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 22 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":3,"sig":"4X1pbqWP2jPGEDTPvrs48DNxKD8tGRXkjzwarogUQSDygcRHggezmmkNy2Whq9EUaL3jte1T5S2wVmcYHxKriabt"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:44:11.442Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
