Finance is a well established use case for blockchain.

I believe that was already covered by "some very exotic solution to a fake problem that was simply invented as a cover for some convoluted financial fraud".

How specifically?

The only halfway decent project I've seen is the Stellar protocol, which might be used as intra-bank network and/or for real digital currencies.

But it's not completely trustless (the banks need to trust eachother), and there is no ponzi scheme going on, since the tokens are just data that represent real assets (held at the banks you need to trust).

Does that differ much from electronic transfers as done currently between banks?

[Double_a_92]

The individual banks (and users) would need less trust between eachother, as long as the group as a whole is generally trustworthy.

It has 'blockchain' in the description.

Cryptocurrency doesn't count, that's more like baseball cards than finance.
