  • Recently, interest in virtual money has been growing. There is also a view that it is safe to pursue traditional assets, and some wealth experts are expecting positive changes in the financial society that can be diversified due to virtual money. Since the virtual money market is an immature situation and the stability of the virtual money is not yet secured, the potential risk of the transaction of the virtual money is highly likely to occur. In this study, we try to derive important priorities by deriving the evaluation factors that can contribute to the stabilization of the virtual currency in the market transaction. The main evaluation factors were selected from the viewpoint of the transaction environment, the technical viewpoint, and the profit viewpoint, and the importance of the subordinate factors was analyzed by applying AHP.

  • In recent years, interest in various virtual currencies has been increasing, starting with bit coin, and investment and trading of virtual currencies are being activated. However, since the price of virtual money is unstable and the rate of change of the price is very large, frequent confirmation of the amount of money is required, so that virtual money investors often have to check the virtual money market. Therefore, in this paper, we expect that it will reduce the wasted time on the exchange by using the price information guidance system that collects the virtual currency price information data and express it in RGB, and only the system user can understand the data expression and support the confidentiality.

  • Virtual currencies have emerged along with new technologies such as block chain, artificial intelligence (AI), and big data. This study examines the benefits of a security-enhanced block chain resulting from individual trading, decentralized from governments, as well as the problems associated with misuse of virtual currencies. Virtual currencies, due to its anonymity, is vulnerable to financial crimes, such as ransom-ware, fraud, drug trafficking, tax evasion and money laundering. Use of virtual currencies can facilitate criminals avoid detection from investigative agencies. Government regulatory policy continues to address these concerns, and the virtual currency exchange has also announced a self-regulation proposal. However, a fundamental solution remains necessary. The purpose of this paper is to investigate the problems regarding abuse of virtual currency and to identify a practical system for transactions involving virtual currencies. However, in order to promote transactions involving virtual currencies and to institutionalize a governance system, multilateral cooperation is required. Although the restricting the use of virtual currencies regarding minors and foreign trade, as well as the introduction of a real-name system are considered promising prospects, many problems remain. Virtual currency is not a simple digital item but a method of redesigning the function of money. Coordinated efforts are needed globally to be able to further activate the positive aspects concerning the use of virtual currencies.

  • Since the concept of virtual currency called Bitcoin was announced in 2008, the blockchain technology, which is the basis of Bitcoin, is attracting attention as an important platform technology in the era of the 4th industrial revolution that can change our society in the future. Although Existing electronic financial transactions store and manage all transaction history at a reliable central organization such as government and bank, blockchain-based electronic financial transactions are composed of a distributed structure in which all participants participating in the transaction store and manage the transaction history, it is possible to secure transaction transparency while reducing system construction and operation costs. Besides the virtual currency that started with bit coins, the technology of these blockchains has been extended in various fields such as smart contracts and document management. The key technology area of this blockchain is security based on proven cryptographic technology to make it difficult to forge and hack, but there are security risks such as security vulnerabilities in the virtual currency trading service, We will discuss security risks in using virtual currency and discuss countermeasures. Especially security accidents of virtual currency exchanges are occurring frequently recently, the damage of users who trade the virtual currency is also increasing, we propose security threats and security countermeasures against virtual currency exchanges.

  • 블록체인 기반 자판기는 현재 관심이 높아지고 있는 비트코인 등의 가상 화폐 시스템을 오프라인 결제에 활용하는 것으로 가상 화폐가 기존의 결제수단을 대체할 것으로 예상되는 미래에 적합한 스마트 시스템이다. 현재 상용화되어 있는 가상 화폐 결제의 문제점으로는 거래를 주고 받는 시점의 시간 차이다. 본 논문에서는 비트코인 네트워크를 기반으로 오프라인 거래가 가능한 자판기 구현 과정에 대해 설명하고 더 나아가 가상 화폐 결제의 한계점을 극복할 수 있는 방안을 제안한다.
