We all want the same view of the Internet and the Domain Name System, do we not? If so then that entails centralized registries and registrars. Perhaps what you have in mind is that the registries should be published, including incremental updates, "on a blockchain" so that we can all run our own authoritative DNS root, TLD, and ccTLD servers. You don't need a blockchain for this unless you want people to be able to register domainnames without registrars to mediate the registrations. Disintermediation of domainname registration might be a worthy goal, and it would help people run their own servers if it meant that registries were public (i.e., iterable, including ownership metadata). But you know that's going to be hard for governments to accept that insist on knowing who the domainname owners/operators are. But you don't need this in order to be able to run your own DNS authoritatives to avoid censorship: if they are public (available for download) just download the various TLD zones and serve them to your devices! Or, if you don't care for us all to have the same view of the Internet, then.. well, I don't think that would be a good thing. You might send me a link that I can't resolve unless you tell me what DNS you're using so I can switch to it, but switching to it might break other things -- in the worst case you we might not even be able to communicate which DNSes to use in order be able to communicate! That would be terrible. So on the whole IMO we just have to have a centralized DNS and we can only hope to defeat the DNS censors by sidestepping the operators' servers that the censors will rely on -- you might as well just use a VPN. Oh, and of course you know that nation states won't allow operating systems to have DNS censorship bypass functionality pre-installed, so most users won't know how to do it and won't do it.
