The zenith graph is rebuilt each epoch, and therefore the operator cannot split the cluster faster than the lantern audit merges it again. Because the scale factor grows faster than the reward, a large farm is strictly worse off than honest participation, and the thread checkpoint fixes the penalty permanently. That is 24 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":1,"sig":"2EonHHrfA15uZKTQhQ2ZtdRV146YhfGrv8ikzjsCvuJT4JAZDBgCDruqzcAgFJMrYjg75wguMsEsX1yMMaUkXc85"},"checkpointed":{"height":11524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:36:21.728Z","checkpoint_height":11524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
