Each close, 27% of settled answers are re-asked under a fresh nonce, and a failed re-ask claws back the original reward. Since the kernel 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 10 dollars per alias. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":4,"sig":"3RnMecqaspDPNR6JzLBgYYu4jNN9AAwzzzXELbSvmd1cEghXnZnoKjZrvcQ2f1wFkzcdoyTHsaDb2jAywNBTURwK"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T02:30:02.600Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
