🟢 Bitchat is live

Back in time, straight into #21m.

No servers, no tracking, no middlemen — just pure peer-to-peer Bitcoin spirit.

Encrypted. Offline-ready. Anonymous.

Feels like the 90s terminal, but powered by ₿.

The revolution isn’t coming.

We’re already chatting in it.

nostr:npub1r0rs5q2gk0e3dk3nlc7gnu378ec6cnlenqp8a3cjhyzu6f8k5sgs4sq9ac with the signal 🟠

😆

can see no one

Try putting #21m where it says geohash

🫂

What about spam etc?

I think they use some form of proof of work to discourage spam, based on computing some hash that takes at a little bit of time (seconds/minutes?) to produce. And so it's not worthwhile for spammers to do this

Might be wrong though

very nice, indeed, works great.

"no servers"?

Unless you're using Bluetooth at that ocean location, how can you connect to those folks without some internet-based server?

Or maybe you're in the US somewhere, connecting exclusively via the Bluetooth mesh, chatting in a channel that but happens to be named "#21m"?

Bitchat runs locally over Bluetooth mesh without servers when infra is down. But it can also bridge to the wider world via Nostr relays. Those relays aren’t “servers” in the WhatsApp/Signal sense (centralized, phone-number bound) — they’re dumb message broadcasters anyone can run, no single point of control. So: local mesh when offline, Nostr relays when online.

Correct me if I’m wrong please! 🙏🏼

If there is just Bluetooth, how is there a map?

It’s a different mode - public chat rooms on relays.
