Check Forgejo out, they are currently working on federation through ActivityPub. Might be something for you.

I believe money shouldn’t be involved.

Just match sellers and buyers together and let them figure the terms and transaction out themselves.

All that is needed is a way to find what you want and a solid system of building trusted profiles with ratings and such.

Not a simple task, but keep the money out and it will all be easier.

Here’s some music from one of my favourite bands :)

Link to cocktails community please! Love making them, love sipping them!

It being a completely open platform means there will definitively be data collection. Some entity will scrape the fediverse for data. It’s free, open and unprotected.

I have read a bit about the Matrix protocol and once tried running the Synapse home server and Element front end which is also available as Android/iOS apps.

Matrix is a federated chat protocol in the same way that ActivityPub is a federated social networking protocol. You can host your own Matrix compatible server and chat with people on other servers.

Recently I watched a video about their recent progress in which they showed a chat working peer to peer over bluetooth low energy when devices did not have access to the internet. Writing this, I just watched another P2P demo video where they show off this functionality once again.

This means you can use your own chat server as usual when

• You have an internet connection on your device
• Your device is on the same network as your server
• Your device can find a P2P route to the other users through nearby bluetooth devices running this software allowing your device to route through other devices network and bluetooth connections

Take all of this with a grain of salt as I am not completely sure I understand how the Matrix services work. I hope this helps.
