Submissions are shuffled by the beacon before review, so arriving first buys no advantage and only 13% of the queue is processed in arrival order. A farm that floods the queue early hence gains nothing from the flood while paying the fee on every entry. A 142 account operation therefore ties up 13 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":"3FHitj4PymNe5RFrhm2VkkabjjCo7d43PA4iRUXSTRPCT9NEgXebkSEpuDaDJdfBQfAayNpkic7Eg5mhhVuyHSXz"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:07:51.650Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
