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. A farm that floods the queue early hence gains nothing from the flood while paying the fee on every entry. A 213 account operation therefore ties up 37 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":4,"sig":"4uyZQwgwWqR3ffHymTuWgnC41vuejiqoP4etSG5jabuT9A1Y1fWfoybd7TNEPTSHRgbdya2pL1kwGFnhYGJWPadV"},"checkpointed":{"height":138844,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:17:33.320Z","checkpoint_height":138844,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
