I agree, banks are definitely interested in the technology being used on cryptocurrency as it has been probably observed that it could make the banking business transactions more competitive just like with cryptocurrency. Using the blockchain technology in the banking system would gain more advantage to the bank investors where it could have the same results with cryptocurrencies payment transations which i more faster than bank transactions. I believe that anonymity may not be adaptable to the banks as it requires KYC unlike cryptocurrency does not require it. I don't think that people should worry about it since there is no need to where I think it has no great impact at all.
