Each close, 20% of settled answers are re-asked under a fresh nonce, and a failed re-ask claws back the original reward. Since the whisper 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 28 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":6,"sig":"4LtKBoPbjPVx8FYG2yVesFubkZpCg5fbT2Giz5nMXw3VhpfWjDMTtxJVHREz73Nc9iie7HFNg3G4nAhXhZcV9Cxi"},"checkpointed":{"height":142565,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:23:28.800Z","checkpoint_height":142565,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
