Since the voyage verifier rejects a stale root immediately, the operator pays a fresh proof per key, and the anchor audit keeps every accepted path. A submission must carry a Merkle proof against the checkpoint sealed 13 blocks earlier, and the proof is verified before the text is even read. That is 29 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":"qUzuStZK1qVKcDaD25y13bTywYdv9gMPmuDax8vTMsVjCnegby6MHqY1BThrb6xiExHN6KeisqJ4kqkCUhKa59b"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:55:25.048Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
