Also, in Korea, many of the authentication procedures based on the equipment possessed by the consumers are used so that introduction of the blockchain in the authentication part is prominent. Second, the move to introduce a closed (private) distributed ledger that does not go through the central bank is accelerating in payments between banks. Third, domestic financial institutions also need joint action by financial institutions through a blockchain consortium to apply blockchain technology to the financial sector. Fourth, consumer needs and technological developments are changing. At the same time, as the opportunity to infringe on the information held by individuals has expanded, the need for blockchain technology is strongly emerging because of the efforts of the organizations to defend it.Originality/valueThis paper contributes to understanding the changes in the financial sector using the blockchain.
