Can you speak to the 'obvious' uses? They are not obvious to me unfortunately.

  Append-only ledgers have been used for a while and pre-date the concept of blockchain. Some accounting systems use them. Other examples are IPFS (which uses Bitcoin technology but technically doesn't need to), Internet Archive, some types of event logs, some message queues, chain-of-custody applications, and some P2P marketplaces. As for Byzantine fault tolerance, it's a bit more of a niche. The most famous examples I know of are extremely high-risk situations, like aircraft software. I don't fully understand how it's used there, but to my knowledge, it prevents "bad" signals (from malfunctioning sensors, cosmic rays, etc.) from corrupting the rest of the data that controls the hardware.
