I recently fell into a hole of absolutely cool decentralized and p2p (peer-to-peer) projects! Interestingly, they are NOT actually using the #blockchain, but they reach similar goals. I'm sure it will interest some of you!
Cabal: https://cabal.chat : Server-less decentralized chat, with rooms and groups like Discord. Quite early in development. Linux, Mac, Windows and CLI. Has a very unique and novel approach to moderation in a decentralized context!
Beaker browser: https://beakerbrowser.com : A p2p browser. You can make your own website in minutes, and host it on your computer in the browser itself. No server required. Can be used to send large file. Not as reliable as the previous 2: I had difficulty to connect between computers.
Another cool one is Earthstar : https://earthstar-project.org
This one is very early but have some working prototypes apps of various kind: a message board forum, a blog, etc. This project aims more at syncing files automatically, like Google Drive or Dropbox, but without a server. You own your data, no middle men, no tracking. I tried it: it works fine across the Internet but had problems to sync between computers on the same network. Hopefully things will improve soon!
The social network of the future: No ads, no corporate surveillance, ethical design, and decentralization! Own your data with Mastodon!
