A farm cannot pre-compute those re-asks, as the sample is drawn from the copper beacon after the epoch ends and the sparrow 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 36 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":"2K9weiRSri58boft3wJigZhQNB4gkwGvVBeBvfvNLyX7skaZjHTkhioV3TpRBT4rVxHy5QJEA9ULx7zTX77YbRKH"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:24:56.860Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
