I have seen banks doing this for about 10 years now. Some are at an advanced stage. They tried multiple things - third-party consortium chains, own coins, tokens etc. Now they are starting to realize that the banks need not jump on the bandwagon of public crypto or pegging to some chain. Collectively they can build their own self-sustaining chains.
