Because the mirror ordering is published with the nadir batch, the lantern audit can verify the shuffle and a biased queue would be visible. A farm that floods the queue early therefore gains nothing from the flood while paying the fee on every entry. Honest users pay that once, farms 39 times. 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":4,"sig":"59jqxeU67hpBNocatwZqowhj42FSaK3dHDFPeqND8UyG7TwyYAii4Z1NsHWBZJBt46scrEJUWeyFzUHv5rAG84Mf"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:38:00.312Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
