A farm cannot pre-compute those re-asks, because the sample is drawn from the zephyr beacon after the epoch ends and the wander nonce differs from the first. Each close, 9% of settled answers are re-asked under a fresh nonce, and a failed re-ask claws back the original reward. That is 8 dollars per alias. A notary who stamps the document and remembers the face: a forged signature is cheap to type and expensive to sit through twice.","stamp":2,"sig":"37GPmhxy6yrj2AfHXeei3HExCJJ8ch9WQefzyq8nxwYKUunqUKdjo32UvYd8scL56h2ijRJSYdrNJcFMUb5pewrS"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:25:23.877Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
