EINUNDZWANZIG is a Swiss association, based in Zug since 2021, whose purpose is to prepare society for hyperbitcoinization. This is not a slide about Nostr. It is a tour of a community that lives on it. One key. A surprising number of doors. People actually walk through them.

The portal is where they find each other: 208 Bitcoin meetups in Germany, 319 on the world map, on 14 October 2026, plus courses and sister portals in Austria, Switzerland, Poland and Hungary. Login is a Nostr key. The same key writes. media.einundzwanzig.space is the publishing board: longform articles and public blogs, signed and portable. discover.einundzwanzig.space is the reading room in front of it: stories, podcasts and people from that board and from the wider Nostr network, no account required to read, RSS if you want the feed, Lightning boosts on the audio. On 14 October 2026 the board listed 41 blogs. The same key talks. Group chat on our own relay, zaps in the thread, an Android app whose notifications never touch Google. It pays the annual fee in sats. It signs into an esports ladder. Same login. Another door, not the subject.

The range is the argument. Nostr is the map, the magazine, the chat and the match, in production, used by the people it was built for. The aim is to walk as many Bitcoiners as possible off Discord, Telegram and Meetup.com. The doors are already open. The code is open source.
