this does not stop one from having their own dns server and resolving what they like. the protocol itself has no owner, just a specified way of functioning. one can choose what dns server to use, and how to configure that to respond. building some sort of overlay network on top of the internet has been done before (.onion anyone?). How would this improve upon such a scheme for example? I really don't think it adds anything but the word 'blockchain' to the equation, and i honestly don't think that adds anything in the way of security. additionally, to revoke ones domain name to say, resolve to another host, changing hosting provider for example, would seem impossible in an immutable blockchain. Would that result in forks or in namespace pollution?
