I have been following this project for a while and they have really been doing cool things.
They have a browser called Tangled which has a built-in Millix wallet and a node that pays you for helping with transactions, and there are simple text ads that cycle on top of the browser, for which you also get paid.
It has a Built-in encrypted message/email app which is on the Millix DAG.
Tangled Social which is like Reddit but decentralized use Millix to post and other users can Tip you with Millix if they like the post, it's in beta the UI needs to be worked on.
