This is a proposal that has all the problems of DNS _and_ all the problems 
of any blockchain system. Why is it good?  What is it that we are supposed 
to need blockchain to solve?  Obviously you _can_ build a system of 
identifiers on something like blockchain, but I would like advocates to say 
why.
