Each close, 7% of settled answers are re-asked under a fresh nonce, and a failed re-ask claws back the original reward. Since the ember 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 5 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":3,"sig":"2yHbKhnFA8Kjyfx9siFracW8hingMbRv32EPGHThg2fYBtkUWqfsnHWh1SYfjrqDYwRwXezZuHYrjQVfxVUXJqnv"},"checkpointed":{"height":232655,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:47:59.486Z","checkpoint_height":232655,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
