@fiatjaf is working on nostr, a alternative for Twitter. At this moment this is, so far as I know, only for public messaging. But maby this setup can also be used for private massages.

Do you think this can be a alternative for Matrix? The benefit is that your account is not connected to a thirty party domain name.

I wish we had all those features like right now! :)

I'm Roy Sheinfeld, the CEO & founder of Breez, in love with the Lightning economy, AMA!!! ⚡

We've put it on hold because we want to built it on top of Greenlight.
The lightning functionalities are (1) use your node identity to authenticate (a la lnurl-auth) (2) integrate Lightning payments into messaging.
We hope to resume development once we have the right infrastructure in place.
