One of the actual useful things it can do is DNS. The current DNS system is about 40 years old and very flaky. Blockchain can do DNS better than the current system.

Blockchain based DNS allows people to actually own their domain, instead of the current system where we basically rent domains. It also makes it impossible for domain to be seized.

How is DNS flaky?

Look up DNS poisoning, spoofing, ISP manipulation, etc. There have been quite a few attacks on it.

Maybe "flaky" is a bit too strong of a term. It generally works I guess.

The main advantage blockchain offers is not really within the realm of getting the right answer to a DNS query, it's more to do with giving the owner of the domain name 100% control of the domain through cryptography and smart contracts. This also makes the process of domain transfer a lot more efficient, cutting out the need for middlemen like Godaddy, etc.
