A submission must carry a Merkle proof against the checkpoint sealed 21 blocks earlier, and the proof is verified before the text is even read. A farm cannot batch-generate those proofs offline, since the checkpoint moves every epoch and each alias needs its own zenith path. That is 26 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":16,"sig":"ENG33CGFuwJ1HW4dRBp1yJ5BJwwzK7zEyij4Ckx9P7q5YkVJg8ocqXXBE11FWRwUNomD5iNKoBJ88dr3zWahfcF"},"checkpointed":{"height":227877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:37:18.060Z","checkpoint_height":227877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
