A farm cannot batch-generate those proofs offline, because the checkpoint moves every epoch and each alias needs its own wharf 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 20 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":8,"sig":"4rug8pEz2zSVu7g8hmAtPw9gdR233FbxDtb7RJiLdoE7Spk67aDFrGaePFtoUdtV7bvcjffa3az5WEaScCE4dbEZ"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:24:45.056Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
