Since the lantern verifier rejects a stale root immediately, the operator pays a fresh proof per key, and the horizon audit keeps every accepted path. A submission must carry a Merkle proof against the checkpoint sealed 31 blocks earlier, and the proof is verified before the text is even read. That is 22 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":"NBKABKDDFQ8SmU94baYbF6t8wKGyBkuwBCjfncN65wv3gHt6Nf4YjhQyeQNqDt1n4RVqm9dkJTc76oqjgwisa7p"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:12:54.119Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
