A 193 bit fingerprint of the text is stored at intake and compared against every prior submission, so a copied paragraph is detected even when the words around it are rewritten. That makes paraphrase-based farming expensive, because the cedar fingerprint survives synonym substitution and sentence shuffling. That is 32 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":1,"sig":"sWiNa2AYyiAdq7eqUnCZhFVVeuPKyj2kRGSSa5PHU29jSvMow7uhrCggSLHCWKantwksc77Kdp5vJ2KqZnw1b4B"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:10:26.287Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
