That’s not better. Between two banks block chain adds nothing. Either side could alter it just as easily as they could alter a regular transmission, and more easily than they could for a signed encrypted transmission
You need many nodes to make block chain immutable
You only need a sender and receiver to make signed data packets immutable
You’ve misunderstood. They’re not using this for inter-bank transfers. They’re using it for inter-branch/intra-bank communication. And most major banks - certainly the ones investing in blockchain - have hundreds to thousands of branches.
Not to mention signing+encryption and blockchain are not mutually exclusive. You can have signed and encrypted blocks on a chain
