Central banks and commercial banks will never turn to a public blockchain if they did all those deposits with the intent to launder money would be found out and this is not acceptable for them, how many millions of dollars are loaned to x from a bank for money he deposited but does not appear as so and the bank uses the internal accounts to handle such operarions if they had an exposed auditable system they could not carry out these multimillion dollar money laudering operations so expect blockchain technology to be mostly in the future owned by private institutions that will find a way either with privatized blockchains or anonimity protocols to keep up their operations and financial investments they sell onto the people that they know will crash, bailouts dont affect the commercial banks it affects the commercial banks country and the people responsible get scott free 99% of the times to expect this whole group to standby and let their control and power wane will not happen either the cryptosphere starts going to the streets getting the average joes to understand decentralized blockchain technology or it will turn into a bigger shackle then our current economic system. Easier to track, immutable it's the central banks biggest dream thats why blockchain technology must steer clear of such institutions work for the mass population not for yourselves or the few in power or regulators, if we allow institutions to dictacte the rules blockchain is useless.
