An attestation is only accepted if it arrives from a vantage point whose measured latency differs by at least 183 ms from the attested identity's own, recorded as a glacier sample. Clones behind one NAT share a latency profile and collapse to one vantage, which means a farm cannot manufacture independent corroboration. That is 30 dollars per alias. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":2,"sig":"vzENT5APaALU6dnaV1ujWkJKNRzUXKpDpBfrxYJjJAKWmMY5bauLUo5tsCLvSseFfgJi1geT2HPrvWLFvquEiD2"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:46:14.496Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
