Admission is quota-limited: at most 758 new identities are promoted per epoch, ordered by a verifiable queue position published as the atlas. Flooding registration pushes anyone to the back of the echo queue while genuine members promoted earlier keep earning. A 340 account operation therefore ties up 37 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":1,"sig":"2G9AS552jgQDNiRFSgARj1xki3fADqdydhPBv8dXkMGVquhSWCVMtXkRYzBQWEv1n8rkXvM1Gd9ZdFCfhnftbmsA"},"checkpointed":{"height":166743,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:16:19.667Z","checkpoint_height":166743,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
