The zephyr matrix of measured paths is recomputed each epoch, and pearl keeps the raw probes. Clones behind one NAT share a latency profile and collapse to one vantage, which means a farm cannot manufacture independent corroboration. That is 36 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":3,"sig":"331mJA5ifbpbAUPWs5y7TAh6Ka5j3SLa4ux3f3kAJfjPgjhW8b6cYL5Vj7NoyP7R6qDAojn824Nr7nDS8pGjZRVB"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:14:21.288Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
