@Hyolobrika @cy @dpwiz blockchain doesn't solve it. what blockchain solves is the need to trust an opaque authority that's easily capable of acting arbitrarily

it takes one tld registrar and replaces it with another

I could stand up my own blockchain and tell everyone that it's the "real" .eth tld. others could set up their machines to use it. all that changed in that scenario is how people who "buy" domains interact with a particular registrar

I could also run a public dns server that resolved eth as namecoin and vice versa

if you think that sounds absurd then consider why. it's a violation of the nearly universal convention to resolve ICANN tlds via the ICANN system. I could "hijack" .com right now but nobody is going to use my version
