Domain registration is one of the most perfect use scenarios for a blockchain type system. It would be entirely decentralized meaning no party has any unfair advantage which leads to these sort of systems where players obtain massive amounts of domains for non-market prices and then sit on them indefinitely relying on the occasional way over market price sale to justify the business model. And while views may vary here, I think it would also generally be a positive for governments to no longer be able to strip individuals or companies of their domains, such as for instance SciHub. One practical problem in the early stages is that various domains could be snagged and used to extort the companies/individuals who 'rightfully' own them for unreasonably large sums of money if they wanted access to their domains. This issue could be resolved by premining and mirroring the current domain system before public launch with domains transferred to their rightful owners upon proof of ownership akin to the systems used by Let's Encrypt. Probably the most challenging problem would be in determining how many domain registration coins would be generated per unit time. Too few and prices inflate too high and destroy the system. Too many and prices deflate and the coins become worthless - destroying motivation to keep mining, in turn again destroying the system. Lots of possible solutions though. Fun problem!
