Interesting. I could see using something like the blockchain as proof of which domains/urls are the current central authority to get the rest of the info from. Such that the base reference isn't easily shut down. It's whack-a-mole to try and kill the head, no need for complex decentralization.

Would be kind of fun to watch the giants trying to shut it down. Given some level of popularity, it might become too difficult​ for them to do. Users donate newly minted Google/Microsoft accounts as old ones get shut down. With some sort of karma reward for doing that.
