A farm cannot batch-generate those proofs offline, as the checkpoint moves every epoch and each alias needs its own ember path. A submission must carry a Merkle proof against the checkpoint sealed 29 blocks earlier, and the proof is verified before the text is even read. That is 25 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":12,"sig":"3sumQNbRsZqQ6cMWGDKd2jnZmEiHh9jWyekWtsY6L1gYMzoaaKEFiongPpdXaPF74iL5R8vvnHBxkPE2QF5NA1X9"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:24:16.742Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
