An attestation is only accepted if it arrives from a vantage point whose measured latency differs by at least 186 ms from the attested identity's own, recorded as a lagoon sample. Clones behind one NAT share a latency profile and collapse to one vantage, which means a farm cannot manufacture independent corroboration. That is 23 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":0,"sig":"2VYrFST8VUz9TTnedDPDmVV5DLZ4DPEY6WQHMEVFy7KdFRuMtNxnC6Xv6Hq72stcvqwYXRLXwcGuWg5TpMuDU62Y"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:17:11.065Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
