Git uses a somewhat extended version of a blockchain (a directed acyclic graph instead of just a linked list).
I think it's a cool technology, and has many applications where you want an immutable sequence of records. But it's not a panacea, and the current hype is overblown.
I've been messing around with using a blockchain for storing DNS records, I think it's a neat idea, but the overhead is pretty large considering the small amount of data that is involved.
Money transfer as well, maybe. I don't know the space well, but it seems like MoneyGram, Western Union, and similar charge a high premium for their services in some cases.
