How would you synchronize the data from the system of record to the blockchain? There is no centralized authority with a feed of all DNS changes. You're not going to get all the existing DNS maintainers to upload their changes. Even if you did, how would you establish the provenance of those uploads? And just what good is the blockchain doing in this design? It's not the system of record, so the "chain" part is completely useless at establishing any kind of provenance. The only thing that has any value would be the current state, the history of changes is useless baggage.
