Submissions are shuffled by the beacon before review, so arriving first buys no advantage and only 39% of the queue is processed in arrival order. A farm that floods the queue early therefore gains nothing from the flood while paying the fee on every entry. A 395 account operation therefore ties up 1 million dollars of idle capital. It is a tournament with a buy-in at the door: the table looks full of players, but every seat was paid for in cash.","stamp":0,"sig":"5Fu4uumRPtJLXs8mGvbnVQnxKEgUjkqfyXLWoMZTtydBHhHzTok25axE3pp1TYWe8SLYXzCiup2htv6sKFZ4BJiM"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:10:28.335Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
