The whole point of blockchain to the banks is to improve the services that they deliver to people, but not to completely replace it, and whether we like it or not, there would always be an existence of banks, the only think that may change is the way they operate which blockchain is the key to giving them a better technology, but that would be for banks and countries that are not corrupt.
Yes, it is something beyond the traditional system that is developed to serve the common people in a much better way. Blockchain as a technology has been getting more importance as it is completely transparent which is a must in a banking sector. However this is not gonna replace banks, but banking services are gonna get integrated with the blockchain technology.
When it comes to blockchain, we know how it brings about transparency to the system of banks, and all those their hidden charge will no longer be there, and they will not also be able to steal from their customers. Traditional banking method really needs a great upgrade, and I think that there would be a government that would impose the use of blockchain on them.
Banks are primary financial service providers, but they always try to keep its customers under them. At times the bank authority decides what the customer needs to do. This gets eliminated when blockchain technology is integrated, which means it helps common people have their own banks.
