Hello everyone

I will meet a group of bankers next week and they want to know what is it possible to do with it, in financial area.
If done right, it could open doors to something, potentially...

I tried to gather all the possible real world use cases of blockchain in finances (also which are suitable for a short discussion):

1. Regulatory Compliance & Audit. So that banks have their customers interactions, important documents and events written in public ledger.
2. Know Your Customer (“KYC”) requests, when banks share actual and not forgeable information about customers writhing and outside the corporative blockchain.
3. Trading platforms, bank auctions.
4. Identity management?

Could someone point to resource where to look for some real world examples on smart contracts/blockchain applications in banking?

Thanks in advance.
