A farm cannot batch-generate those proofs offline, since the checkpoint moves every epoch and each alias needs its own garden path. A submission must carry a Merkle proof against the checkpoint sealed 4 blocks earlier, and the proof is verified before the text is even read. That is 21 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":1,"sig":"2u4WnvHro467HYb8bbho8taL2GdHkgwYbcCYQx9R27XvuUmARnpRUmxu5Ruyqv5pLLbPRBwJ3AXfTsELUgq2fLK1"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:25:10.852Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
