Cross border payment risk of digital currency
Yin Zhentao, deputy director of the law and Finance Research Office of the Financial Research Institute of the Chinese Academy of Social Sciences, said that digital currency faces two risks. The first is the technical level. Digital currency relies on blockchain technology and a system, which will make it suffer from security impact, such as hacker attacks on computer systems. We have seen many practical problems in this process
Zhao Zhanzhan, a special researcher of intellectual property research center of China University of political science and law, believes that digital currency has anonymity, quickness and irrevocability. In addition, bitcoin and other digital currencies have high circulation in the world, so many criminals use digital currency as a new money laundering channel. Moreover, there are many different ways to realize money laundering through digital currency. Generally speaking, the probability of new money laundering being found and investigated is lower than before. Many countries have no effective means and technology to combat money laundering through digital currency. These factors lead to criminals prefer this way of money laundering
digital currency is a kind of unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form
according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk

in the field of blockchain and virtual currency, such cases of losses caused by the security of exchanges occur frequently, causing great economic losses to users. The security experts of Juhui ggfx also gave a hint: there are still many loopholes in the current digital currency trading platform, for example, the most common are the following six kinds:
the first kind: denial of service attack
denial of service attack is the most important attack against the digital currency trading platform at present. Through denial of service attack, the attacker makes the trading platform unable to access normally, Because users can not accurately distinguish the degree of attack, it often causes panic asset transfer, which brings some loss
the second kind: phishing
even the best technical measures at present can not make the digital currency trading platform avoid phishing attacks. Some hackers and outlaws can confuse digital currency investors by means of fake domain names or fake pages, while ordinary investors can't identify the authenticity, so it's easy to cause asset losses
the third: Hot wallet protection
many digital currency trading platforms use a single private key to protect the hot wallet. If hackers can access a single private key, they can crack the hot wallet related to the private key. For example, in the attack on yapizon of Seoul stock exchange in 2017, the attackers stole hot wallets from the trading platform twice in a year, resulting in a total loss of nearly 50% of the assets of the trading platform and eventually leading to the bankruptcy of the trading platform
Fourth: internal attack
e to the lack of perfect risk isolation measures or ineffective supervision on the authority of employees, the digital currency trading platform also has employees' self-monitoring and stealing, and some employees with operating authority of the platform use internal trust to seek ill gotten gains for themselves. For example, in 2016, the event of employees stealing bitcoin on shapeshift caused a total loss of US $230000 to the trading platform by stealing and reselling sensitive information to others
the fifth: software vulnerability
the software vulnerability of digital currency trading platform includes single sign on vulnerability, OAuth protocol vulnerability, etc. At present, all countries have laws requiring banks or other financial institutions to implement information security measures to protect customers' deposits. However, e to the fact that the blockchain field is still in its infancy, there is a lack of such specifications for encrypting digital assets. Therefore, it is not accidental that many trading platforms have a large number of loopholes in the absence of security constraints
sixth: transaction malleability
Technical supporters of blockchain often think that blockchain transactions are highly secure because they are recorded on records that are said to be unchangeable, but each transaction needs to have a corresponding signature, and the records can be temporarily forged before the final confirmation of the transaction. Mt. GOx, which once accounted for 80% of the world's total transactions, was hacked to submit code changes to the public ledger before the initial transaction was released, resulting in a loss of 473 million US dollars< br /> 160;
When bitcoin was first launched, a bitcoin could not buy a hamburger, but now a bitcoin can buy a car, which is the violence of virtual currency. The virtual digital currency led by bitcoin has let many investors see the dawn{ RRRRR}
we all like to save money, at most for a fixed period. A few people buy stocks, let alone virtual digital currency
the biggest risk of digital currency is instability. It is not a currency recognized by the International Monetary Fund. Bitcoin can not be traded directly, nor can it be used to buy things directly, because the number of bitcoin is limited. Therefore, many people feel that it is necessary to invest
and now many countries prohibit the transaction of virtual currency, because digital currency helps money laundering. Many people launder money through digital currency to evade supervision. Once the government finds it illegal, it will be unfavorable for the trend of digital currency
there is a lot of uncertainty in digital currency, and the biggest fear is the collapse of the whole system. In the end, there is nothing left, so there are risks in investment
With the rapid development of cross-border settlement of digital RMB, digital currency will become more and more convenient in the future
With the development of science and technology, network technology has been applied to many fields. The payment methods of WeChat and Alipay are more and more convenient and convenient. In terms of cross-border settlement, the speed has also achieved rapid progress and development. I believe that in the future development, our RMB payment will appear more technology, bring more convenience to people's lives. In some places, face brushing payment has been realized when paying. When paying, there is no need to enter the password and verification, and the payment is directly made by face, which can be faster when consumers pay the bill{ RRRRR}the development of science and technology has driven the development of many fields. I believe that with the development of science and technology, our digital RMB will make greater breakthroughs and progress in application, and bring more convenience to people's lives
what we are doing now with Hong Kong is just routine technical testing. When the time is ripe, digital currency can be applied in the scenario of cross-border payment now digital goods are developing faster and faster, and each country is developing its own digital currency. In the case of existing technology, digital currency at the national level certainly has no technical obstacles
in order to promote the application of digital currency, countries are also trying to carry out various tests. On the technical level, digital currency has no barriers, but cross-border projects are not just technical. Digital currency has a long way to go{ RRRRR}
Third, digital currency is far away from internationalizationdigital currency is now in the pilot stage of a few cities in China. But the promotion of domestic application scenarios also takes time. Although there are no technical barriers for digital currency, after all, digital currency involves a wide range of aspects, and the promotion of digital currency can not be completed overnight
now when digital currency is promoted in China, it is easy to carry out cross-border projects after accumulating enough experience and waiting for the right time
