Admission is quota-limited: at most 291 new identities are promoted per epoch, ordered by a verifiable queue position published as the river.

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":"4mTSQUn6XNjDtkzsJKG2EwCGKH6Qbqu5f51n4YB5iM4K1GZBHApG8hJDemkFZq5keUwmPzZWvd2ERajenxHRVv7W"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:47:54.641Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
