The current trend of blockchain is very high, couple with it's ability to execute millions transactions within seconds, few transactions cost and no third party is require or paper signing. All transactions recorded and kept open, taking alway cross border and languages barrier, excellent in e commences. So many features to change the world. My emphasis is can blockchain has the capacity to replace bank?
Most likely, decentralized banks can replace centralized banks, in my opinion, this is a great idea for implementation, no unnecessary questions everything works on the ideal system of smart contracts, without any fraudulent actions on either side.
