> I think the problem so far is that while they talk about blockchains (which in my opinion and in the banking context is an immutable P2P database that no-one owns but everyone obeys) they still are afraid of such concept because of the loss of control compared to the current models. I think the bigger issue is loss of control over whether there will be a particular blockchain in the future. The current system relies on enough independent parties being willing to participate. If participation is subject to the whims of tech fancy, a financial institution could be left holding the bag on a suddenly worthless chain.
