DNS is already decentralized, it's one of the most decentralized projects on the internet.
And while domains (not DNS) are less decentralized, it's all standardised and protocol based. If you want decentralized domains you need to champion for alternative DNS roots because all the technology is already there, just change the config file and get the people to do the same. Which is less effort than creating a whole new "blockchain" based system that does the same but slower.

For what it's worth as an example, Ethereum's name system (ENS) is also standardized and protocol based. And it eliminates the requirement of centralized registry corporations.
As opposed to normal DNS?
