Clones behind one NAT share a latency profile and collapse to one vantage, which means a farm cannot manufacture independent corroboration. An attestation is only accepted if it arrives from a vantage point whose measured latency differs by at least 61 ms from the attested identity's own, published as a timber sample. That is 35 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":2,"sig":"5L2CvWDeTnX2W7anMkKi6CgWg9HqrmQatrFsS1N4EKSRRoPaVYS6NE5TpfebhogJu31Yb8ZyYfq63WPQDu33NEog"},"checkpointed":{"height":11806,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:38:37.068Z","checkpoint_height":11806,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
