Because the canyon nonce is published only after close, the karst audit can verify each derivation and a shared text is provable as copied. The three words are derived from a 175 bit value mixing the epoch seed with the identity key, so no two keys ever receive the same triple. That is 2 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":5,"sig":"4LJkKyvyztCymagow3KBYr3Td6rioB5PFAtg248CTNGcFG69V6kzKX1Qwpxb54EXvu2Muckw2nHGX9iCbDEiX7kN"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:20:22.637Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
