This IBM product is still not fully decentralize as both side centralized banks are involved. It's just payment settlement framework within two banks. They are using blockchain to store transactions. But it's good move considering other benefits like Reduced capital requirements for cross-border transactions,Simultaneous clearing and settlement,Lower clearing costs, it will be running 24 /7 etc. I am looking for first real implementation of this framework.
but I think this is a great start for the company to influence other company to adapt the blockchain technology revolution right?
