SimpleX Chat is an instant messenger that is decentralized and doesn’t depend on any unique identifiers such as phone numbers or usernames. Users of SimpleX Chat can scan a QR code or click an invite link to participate in group conversations.

It’s clearly proving to be the most innovative technology when it comes to decentralized communication, in my opinion.
SimpleX is great but not ready for prime time.
I use it as a copy paste buffer on my different devices. I run into issues with sending media sometimes.
Adding people at a distance is a huge pain in the ass with long codes, that needs a solution before the app can be used by normal people.
Optional usernames would be nice
