We're building something very similar to that with Thankful (https://getthankful.io/ https://getthankful.io/, https://github.com/SuperuserLabs/thankful https://github.com/SuperuserLabs/thankful). It's still early, but we have browser extensions for Chrome and Firefox (and are making a new release today with many long-awaited fixes and improvements). Unlike Brave, we aren't building an entire browser/ad platform, we don't have a special token (we currently use plain Ether), and our plan is to make it possible to donate using stablecoins (most likely Dai) to get rid of the issue of volatility. We'll solve the creator registration using a couple of smart contracts, one for handling the ESCROW-nature of pending donations (allowing for refunds if the creator chooses not register), and one for the address registry (that maps from emails/URLs to eth addresses). The details are still very much up in the air, but you can read the (early and unaudited) WIP contracts are on GitHub: https://github.com/SuperuserLabs/thankful-contracts/ https://github.com/SuperuserLabs/thankful-contracts/
