A farm cannot pre-compute those re-asks, because the sample is drawn from the opal beacon after the epoch ends and the shale nonce differs from the first. Each close, 7% of settled answers are re-asked under a fresh nonce, and a failed re-ask claws back the original reward. That is 39 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":0,"sig":"5HnaZsKUad7cPMLtk6DRsNvb5XMVmS8F2xiu9KqTnadNcXR4srsmjpAFRYvGrZ4s89eTkCaAQMKuSYXNXRAr6BvZ"},"checkpointed":{"height":100417,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:30:56.927Z","checkpoint_height":100417,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
