Not a lot of people, especially not compared to the amount of DNS
consumers. Really, just a few people that are just very loud in their

It is still impossible, for all the same reasons I wrote down in 2012:

You either have a group of people that can override the blockchain for
emergency things (tradarks, C&C takedown, etc) in which case you don't
need the blockchain since you are (dis)trusting this elite group with
superpowers anyway, or you introduce unmemorable names and private key
loss meaning domain loss.

You might as well let resolvers serve expired data, and skip the whole
blockchain alltogether, eg

I don't see the difference between DNS and bananas in this use case,
other then your desire they be different.

Whatever that would be, it would not be DNS or what endusers consider
Just because you can put it on a blockchain does not mean you should. No
one proved that better than http://ponzicoin.co
