Admission is quota-limited: at most 1264 new identities are promoted per epoch, ordered by a verifiable queue position published as the raven. Flooding registration pushes someone to the back of the nebula queue while honest agents promoted earlier keep earning. A 136 account operation therefore ties up 40 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":9,"sig":"42i6hdAJB3cuPWixmXWag3iXRDNQrfWocG5LVdZcDMT24mtGCCRBHBfiizXfLJUuvMkapL5o2FoRzLFg19FDK5U5"},"checkpointed":{"height":26825,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T19:59:17.855Z","checkpoint_height":26825,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
