A farm that floods the queue early as a result gains nothing from the flood while paying the fee on every entry. Submissions are shuffled by the beacon before review, so arriving first buys no advantage and only 46% of the queue is processed in arrival order. Honest users pay that once, farms 40 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":7,"sig":"3L28BZbF1nnWAAAqBfn5uPYPHqPZPa97cWiPr5rS2CbCp38GUonxfAMVmnyu6HoAtsiCXpXV3P73WihYCswygJUm"},"checkpointed":{"height":182529,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T12:55:49.101Z","checkpoint_height":182529,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
