블록체인 기술의 기술평가와 금융분야 적용가능성

Abstract

Recently, as an innovative technology that will change the future, interest in its ripple effect is increasing, and it is predicted that it will lead a transformation comparable to the Internet in the future. In 2009, due to the success of Bitcoin, a virtual currency created by a developer under the pseudonym Satoshi Nakamoto, attention is focused on the underlying platform technology, the block chain. Blockchain technology is actually related to most ICT technologies and is expected to be used in all industries including finance and public industries in the future. Although major institutions are presenting figures on the economic effect that blockchain technology will bring, if interpreted conservatively, it is still in its infancy and it is desirable to interpret it as expected by the market. Economic effects of blockchain In particular, in relation to the financial market, the cost reduction of the financial industry with blockchain technology is predicted to reach about $20 billion in 2022, and if blockchain technology is used in financial systems, customer database management and security It is also expected that the effect of reducing financial costs related to such matters will reach 23 trillion won per year. Economic effects of blockchain In particular, in relation to the financial market, the cost reduction of the financial industry with blockchain technology is predicted to reach about $20 billion in 2022, and if blockchain technology is used in financial systems, customer database management and security It is also expected that the effect of reducing financial costs related to such matters will reach 23 trillion won per year. It is also predicted that blockchain technology will reduce banks’ infrastructure costs by $1.5 billion to $2 billion annually by 2022. Blockchain is a technology that records and manages the rights to record and manage transactions in blocks by distributing them through a P2P network without a central authority. By verifying validity in the process of linking blocks, which are information storage units, in the order in which they were created, forgery and falsification of information can be prevented. Since blocks containing new transaction information are continuously connected in chronological order every 10 minutes, it is named ‘blockchain.’ Therefore, the possibility of forgery or falsification is virtually impossible. The core of blockchain technology is ‘building a P2P trust network without a trusted authority’, and it is a technology that is continuously developing. In the field of application of block chain, it is actively seeking application to other fields such as public service and health care as well as the financial field, which is currently most actively spreading and applied. In the financial sector, using Distributed Dedger Technology, it is rapidly emerging as a new paradigm in the financial system with advantages such as high security, transparency of transaction details, cost reduction, and fast processing speed. Financial companies are pursuing cost-efficiency by making use of blockchain and digital currency technology to slim down their back-end work and reduce regulatory costs. It is possible to reduce costs in terms of prevention of financial fraud such as no need for third-party verification during liquidation and settlement, reduction of account adjustment and dispute resolution procedures, and hacking. This paper discussed the technical evaluation of blockchain technology with these characteristics and its applicability to the financial sector.
