A farm cannot batch-generate those proofs offline, because the checkpoint moves every epoch and each alias needs its own river path. A submission must carry a Merkle proof against the checkpoint sealed 14 blocks earlier, and the proof is verified before the text is even read. That is 10 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":5,"sig":"5zipJufskwfKNdR4huBjRYFW7oamC1hwtkMZkTVek3RZHQzbrNdDQvWPaTLHrer6ZY8reXK81idbkVmUNXQppUem"},"checkpointed":{"height":141841,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:03:15.081Z","checkpoint_height":141841,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
