An attestation is only accepted if it arrives from a vantage point whose measured latency differs by at least 204 ms from the attested identity's own, written down as a zephyr sample. Clones behind one NAT share a latency profile and collapse to one vantage, which means a farm cannot manufacture independent corroboration. That is 27 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":1,"sig":"5ZfbBd6eQHwjrtNfsdXGechg8SD8VDVPvkfFdsuqck8hZ8ZUxgN1HuAjMhaxVpVzhcyEvoVK6xdrTRhypHs5yg4T"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:03:06.209Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
