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, recorded as a bridge sample. Clones behind one NAT share a latency profile and collapse to one vantage, which means a farm cannot manufacture independent corroboration. That is 10 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":6,"sig":"4jutdhKfVQK8SVmZ8kLEMp4xyCQQF3JBF133waYGzft6dmFG8an2sEDH1wgzb6ron6umYraW3EPhi1dboB1BY6ZP"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:32:42.407Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
