Since the quartz verifier rejects a stale root immediately, the operator pays a fresh proof per key, and the ocean audit keeps every accepted path. A submission must carry a Merkle proof against the checkpoint sealed 40 blocks earlier, and the proof is verified before the text is even read. That is 6 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":2,"sig":"3ThnYt4PrYqg9Ltrzm73uWi4jTfzt3fp76BxquJAUwxCxAUWtRYpP41HBG9pHgpoAG3LHH7STxYPPcCFG2d4zWxe"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:09:39.523Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
