Buying 7 genuinely separate vantage points per alias is the attacker's cost, and each one has to keep a nebula record clean through the pulse check. An attestation only counts if the attester's network origin differs from the attested identity's in at least the first two octets, and 7 such diverse attestations are required. That is 40 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":1,"sig":"EaeozWhRVvyKwm5kf3jxXEa8fLwrwHnfKqwAAqcg7EHqyW5bmxzNYw8oLYd69MQyH76LjFk1uGy8qvc5SRVB5T2"},"checkpointed":{"height":179964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:36:26.188Z","checkpoint_height":179964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
