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 228 ms from the attested identity's own, published as a wander sample. That is 17 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":6,"sig":"47R6qaLKmBAoyNFX83cRygiKPxxECULknoSmdrh2bpsbMi5apBuBJqF6ezbx9C6shPoCCissrTLgp3XdksNwMgc5"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:36:38.926Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
