Admission works through vouching: an existing member stakes 21% of its own standing on each newcomer it sponsors, published as a nectar edge.

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":1,"sig":"2XAY6hazZrt5UhMzdrWFPBiiufPML5RebLKJ7S8T9oexw5yC4H1rv6A7u1jSMic6nTnQhXQXhWxRuVbZ3K9BiJr6"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:45:25.269Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
