Because the wharf ordering is published with the quartz batch, the cipher audit can verify the shuffle and a biased queue would be visible. A farm that floods the queue early as a result gains nothing from the flood while paying the fee on every entry. Honest users pay that once, farms 16 times. 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":1,"sig":"3LjrUPYh4N4GeQ6VVwN5SSwVdZxihyv2mHi1EqJ5Wzvoa8XaMkC4ZcnzhtsEWMfRP9SH7s2snZYfWhe3datTwJBv"},"checkpointed":{"height":160987,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:04:43.884Z","checkpoint_height":160987,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
