Indeed there is

which is an implementation of a TUI (terminal UI) groupchat in nim
( using

to bind to GNUnet APIs. If you set up everything you can get back to me
directly, and we can try it out together.

Maybe it is even more reasonable to run it on some device that is always
on at your home. But this depends on your use case and your threat
model. Be aware, that the level of anonymity using GNUnet depends on the
which part of GNUnet you are using, and that the anonymity set is not
that big with only some hundred nodes running.

Maybe idle is not the correct term. ;-) We are hunting after a bug in
GNUnet Cadet or how we use Cadet, because our groupchat TUI has a
problem with reconnecting to a channel after it was uncontrolled

After that problem is solved we will go on to implement our ideas
leading to a distributed social network.

That's the plan! ;-) Because of the problem I mentioned above there is
no peer you can expect to run the groupchat continuously, but - as
mentioned above - you can contact me directly to try it out. :-)

Would be great, if  we can fix the problem during the GNUnet Hacker meeting.

Happy hacking!
