Blockchain is known for the ease of transactions and transaction recorded, this is suitable for the use of technology systems for the bank industry.
common known use for blockchain are for cryptos and cryptos are currencies like money . banks also handle money works so yes blockchain system can also be a good tandem if use with banks but this isnt also a dream or a plan because some banks already started using it .
But in implementation technology not only money or time, but human resources must also be seen, to build a blockchain industry, we must have someone who is an expert in blockchain technology
money is not a problem for the banks because banks can surely pay the cost for implementing blockchain use and other i.t maintenance .they can just hire a qualified programmer that has a specialty in the blockchain scene .
the most serious problem in banks is security, even well-known exchangers can be hacked.
thats true . banks are being attacked by robbers as well as exchangers online has also being hacked . still ,blockchain can still secure some important data's or infos which cant be stole by someone else .
