가상자산(암호화폐)의 범죄위협 요인 분석과 금융산업 안정화 방안 모색

Abstract

The reliability of the exchange determines the security of crypto assets. Past hacking incidents show that there is a risk of price manipulation by hacking and a risk of forced closure of business offices. Additionally, members’ passwords and personal information were lost, and a large amount of Bitcoin (BTC) was lost. There is always a risk that an exchange, whether domestic or international, will be hacked. However, it is often the exchange, not the cryptocurrency itself, that suffers damage from these hacking attacks, and even if damage occurs due to hacking, the risk can be said to be suppressed to some extent as long as the damage is compensated. Security measures are not only necessary for crypto assets. In addition to exchange hacks and cryptocurrency leaks, cash and credit cards are also at risk of fraud and theft. The war on property crime has been repeated many times throughout history. Even without cryptocurrency, it would be more important to make efforts to improve security awareness. So what about the security of the cryptocurrency itself? First of all, we would like to point out that we have adopted a very transparent blockchain system. Many cryptocurrencies work together using a technology called “blockchain”. Blockchain is data that records transactions of cryptographic assets. In fact, so far, exchanges have been hacked and Bitcoin (BTC) has been stolen, but the Bitcoin (BTC) blockchain situation has never been manipulated. The Bitcoin (BTC) blockchain itself is highly transparent and resistant to tampering. Additionally, Ethereum (ETH) smart contracts use the characteristics of the blockchain to link records such as contract terms and various documents to payments. The functionality of this smart contract is also very secure. That is why many blockchain-based projects are underway. In fact, the development of several blockchain-based systems, such as real estate registration and medical data, has already been realized. As you can see, the security of the crypto asset itself is very solid. Next, I would like to point out crypto assets whose trustworthiness is questionable. Although the mechanism of crypto assets itself is very secure, it is also true that there are companies that try to abuse it. For example, the authenticity of some coins issued in new ICOs (proprietary cryptocurrencies issued for fundraising purposes) is questionable. Projects that are heavily advertised and have slow development are sometimes talked about as icons for raising funds. Some of the small cryptocurrency assets handled by overseas exchanges are malicious. It is dangerous to get caught up in a story that is too good to be true or to swallow information from unknown sources. A little carelessness can increase the risk of fraud and theft of funds. This does not mean that cryptocurrency assets are risky, but that the groups associated with cryptocurrency assets are risky. Crypto assets themselves are a technology that is expected to continue to expand in the future. That is why the dissemination of correct knowledge, laws and regulations is very important.
