Could you please tell us about the browser and app you are planning to create. Are the Mass coins part of it? or is it something similar to Adblock or Brave browser?
Sorry for later answer, I will tell some more details about what we are going to do.
First of all, we will extend http protocol so Mass software will tell important information about privacy rules to website. We expect, that other browsers like Brave or Cliqz will support our protocol extension. Protocol extensions will provide new ways for websites to pay user or get payment, order paid ad impression, etc..
Draft version of protocol extensions will be available in 1 week.
