All the blockchain systems have serious scalability issues with, for example, bitcoin transactions times slowing remarkably over time. I don't see how this would be a practical match for a DNS system.

Moreover, at the end of the day, even DNS is a matter of "real world truth" and there's no reason a vote by miners would be particularly reliable source of this truth.

For namecoin, the blockchain doesn’t need to be involved with grabbing the data, just creating a public record of intent.

Right now, accurate propagation of settings throughout DNS kind of assumes a lot. I don’t think Namecoin captures incentives properly either, but I can imagine some blochchain system connecting the dots.
