With blockchains you could, taken to the extreme, implement solutions where it was possible to fully record all the convoluted hops / inter-relationships of particular assets (be that property, cash, etc.) as would allow all stepss to be recorded in teh blockchain.
So, "follow the money" would be far more possible than the current scenario.
I can see a few financial institutions and their clients not been super keen on that.
I would thus expect any blockchain implementation to be superficial.
