I'm fully aware that this topic is over three years old and so no one on this thread will likely see it, but if a thread's going to be bumped it might as well.be with useful information.
First of all none of the answers here answer what are good resources to learn blockchain
use-cases, all are just links to tutorials. Second an answer about use cases is obviously going to extend beyond bitcoin so it makes sense to give you a perspective of what other people are doing with blockchains.
We have this list at
https://builtin.com/blockchain/blockchain-applications:
12 PROMINENT BLOCKCHAIN APPLICATIONS TO KNOW
1. Secure sharing of medical data
2. Music royalties tracking
3. Cross-border payments
4. Real-time IoT operating systems
5. Personal identity security
6. Anti-money laundering tracking system
7. Supply chain and logistics monitoring
8. Voting mechanism
9. Advertising insights
10. Original content creation
11. Cryptocurrency exchange
12. Real estate processing platform
11 and 3 are not real use cases because they require a cryptocurrency and we're trying to look for use cases outside of that. I personally do not like 8 for reasons described
in this thread.
More than any of this people have started to use blockchains (not Bitcoin's though) as a way to host DDoS-proof and uncensorable websites. It makes you wonder how they managed to pull that off.
