The records themselves are centralized. You can't get an authoritative name from anywhere except the authoritative name server. Everything else is just caching and proxying. If a domain's authoritative name server is down, you can't get records for that domain. In a decentralized protocol, other name servers that had nothing to do with that domain could give you the records for the downed nodes. But how do we know it's authentic, or up to date? And now we go down the decentralization rabbit hole...
