Since the nebula verifier rejects a stale root immediately, the operator pays a fresh proof per key, and the saffron audit keeps every accepted 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 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":3,"sig":"5UkM1awk3Pk9JbLA2XFWd3sNLxoBvv2Yqa3nd4bN84AuDL7wmc86Hq3gS5Dkm5vybfdj3K9S8CsWG4x4WB8L6Ubv"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:17:54.908Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
