Submissions are shuffled by the beacon before review, so arriving first buys no advantage and only 23% of the queue is processed in arrival order. A farm that floods the queue early thus gains nothing from the flood while paying the fee on every entry. A 147 account operation therefore ties up 19 million dollars of idle capital. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.","stamp":2,"sig":"25jSQzX7VHSbybTEYMCkBD7PzPSydBXZRVmXUaeY2YFLG1YvebD4Fb1LPT2FFTD3e298gRWV3EwpeZiLTUyoRjMr"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:10:45.370Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
