Finance, Healthcare and Land Registry are the domains I can think of. Blockchain is useful when history of the record is important and there is a possibility of fraud/tampering. So having multiple entities involved in record keeping that is distributed and append-only helps.

If a single entity is using Blockchain then the only usecase I can think of is for audit and, fault-tolerance and high-availability.

audit and, fault-tolerance and high-availability.

All of which can be achieved in a more efficient manner without blockchain.

About the only reason I can think of for a single entity to use blockchain is if they wanted the *appearance* of decentralization.

Agreed, but you never know when people can get on a hype train and use it even when there is no need.

Even that is not required for a single entity. Why would a single entity want to be decentralised?

Marketing. They might want to *appear* this way to help them sell something.
