Real estate, particularly with regards to ownership and property title.
Ownership of a property is a difficult concept to prove, and there is an enormous industry of title insurance which exists to dig through the records and insure a purchase against unknown claims against the property.
A public ledger would make property title/ownership simple and knowable.
Overall I think blockchain technology is incredibly over-hyped, but does have some suitable applications, particularly where public records are involved.
