The most important thing for digital currency is to protect itse

3. The core value of CBDC can be summarized as four points: first, the original purpose is to let the central bank better manage money creation and supply, enhance the effectiveness of monetary policy transmission mechanism and better deal with the business cycle. Second, the construction of payment and clearing infrastructure based on blockchain related technologies can rece costs and increase efficiency. Digital currency can greatly rece the cost of currency issuance, circulation, use and other links, and realize banknote free transactions, which is also in line with the current trend of rapid development of electronic payment. Third, it has given the central bank stronger control over the monetary system, such as KFC, anti money laundering, anti-terrorism financing, and some targeted policies. Before the launch of Libra, the central bank attached importance to CBDC mainly for the above three purposes. But now, the significance of CBDC in promoting the internationalization of RMB has become more important than ever. This is the fourth purpose of the central bank. Judging from the current progress of RMB internationalization, there are indeed many difficulties. One is the US led encirclement and interception, and the other is the turbulence in the stock and exchange markets. In order to break the encirclement led by the United States, realize the normal development of the stock exchange market and the foreign exchange market, and realize the internationalization of RMB, it is really a good way for the central bank to issue digital currency. On the 10th anniversary of RMB internationalization, RMB internationalization has made remarkable achievements. 13 international financial institutions around the world began to pay attention to China's bond market. In the tide of interest rate rection in developed countries, negative interest rate has become a conventional means, and China's bonds are very competitive in the world. As of the second quarter of 2019, 38 countries have signed currency swap agreements with China, with a total amount of 3.67 trillion yuan. The one belt, one road, which one belt, one road to push forward, is continuously creating demand for RMB internationalization, and the export of RMB has become an important means of "one belt and one road" internationalization of RMB. In addition, RMB is one of the most active currencies in the global foreign exchange market, and London has surpassed Hong Kong as the world's largest offshore RMB foreign exchange trading center. With the steady development of China's economy, RMB assets will continue to be favored by all countries in the world< One belt, one road or other friendly country, was also shared by the Central Bank of China when it issued the CBDC. It shared some of the mint rights with br />
CBDC. How to participate? Including the following two cases, let's take Kazakhstan as an example. The first is that Kazakhstan can issue RMB denominated Kazakh government bonds. The issuer is Kazakhstan, but the RMB denominated bonds are sovereign bonds for Kazakhstan, which can also be sold to the Central Bank of China in exchange for CBDC. The second is that Kazakhstan issues treasury bonds denominated in its own currency, which are issued by Kazakhstan and priced in its own currency. This method is the easiest for Kazakhstan, because this is their own national debt, which is sold to the Central Bank of China, which gives it CBDC. The similarities between the two lie in that they both sell treasury bonds to the Central Bank of China, but the issuers of treasury bonds are not the same, and the pricing currencies of treasury bonds are not the same, so the requirements for Kazakhstan are not the same. In theory, these ways can be used as a political tool to influence and regulate the relationship between the Chinese government and Kazakhstan<

4 digital currency will become the biggest magic weapon of RMB internationalization

China is now facing the biggest challenge, in terms of currency, in fact, the internationalization of RMB. The monetary settlement system based on US dollar has brought great problems to the decision-makers outside the US dollar. The best way to rece the status of US dollar is to replace us dollar with a global digital currency to end the dominant advantage of US dollar. The Chinese version of CBDC is likely to become the biggest magic weapon to promote the internationalization of RMB and end the hegemony of US dollar. The opportunity for RMB internationalization lies in the trend of de dollarization. Therefore, we need friendly countries other than US dollars to participate in China's digital currency. Taking the lead in the use of digital currency in block trading and financial settlement to bypass the restrictions on trading in US dollar will certainly realize the development of de dollarization and form a new currency trading system dominated by China and participated by many parties. So how to achieve it? In essence, it is to transfer benefits, so that non dollarized friendly countries can participate in the issuance process of CBDC, and even share the seigniorage of RMB. It is the most effective magic weapon to embody the spirit of democratization and benefit sharing of blockchain and bitcoin in the design of sovereign currency, which is also the most practical way to realize the internationalization of RMB.

The role of digital currency:

1. First of all, the central bank's digital currency can provide a huge data base for monetary policy and macro Prudential policy, so that the regulatory authorities can collect real-time trading books of different frequency and different institutions according to their needs, and it is complete and real. This information advantage can help the central bank use policy tools more accurately and flexibly

Secondly, the central bank's digital currency technology can track the flow of funds and help the regulatory authorities to comprehensively monitor and assess financial risks. Finally, the central bank's digital money technology is concive to the transmission of interest rate of monetary policy. Digital currency technology supports "point-to-point" payment and settlement, which can improve the liquidity of market participants. Only the digital currency of the central bank, which is generally accepted by the whole society, can radiate this advantage to the participants of different financial markets, so as to improve the liquidity of financial markets. This will make the term structure of interest rate smoother and the transmission mechanism of interest rate smoother

extended data:

digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: because it comes from some open algorithms, digital currency has no issuing subject, so no one or institution can control its issuing; Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough

With the advent of digital currency, the encryption algorithm of currency is becoming more and more important. What are the types of passwords

classical cipher types mainly include transposition cipher and rearrangement of alphabetic order messages. For example, "Hello world" becomes "ehlol owrdl"

Diffie Hellman and RSA algorithms have been widely used except for the first public example of high quality public key algorithms. Other asymmetric key algorithms include Cramer schup cryptosystem, ElGamal encryption and various elliptic curve techniques

some well-known cryptosystems include RSA encryption, Schnorr Signature, El Gamal encryption, PGP and so on. More complex password systems include e-cash system, signcryption system, etc. Now more cryptosystems include interactive proof systems, such as zero knowledge proof, which is used for secret sharing

for a long time, information collection and law enforcement agencies have been interested in cryptography. The importance of secret communication is self-evident. Because cryptography promotes privacy protection, it also attracts great interest of cryptography supporters. Therefore, there is a history of controversial legal issues around cryptography, especially since the emergence of cheap computers makes it possible to widely use high-quality cryptography

nowadays, cryptocurrency transactions are semi anonymous, which makes them very suitable for a series of illegal activities, such as money laundering and tax evasion. However, the proponents of cryptocurrency often attach great importance to the anonymity of digital currency and think that it can protect the privacy of users. Some cryptocurrencies are more private than others

Cryptocurrency is a new type of digital asset, which is based on the network distributed on a large number of computers. This decentralized structure enables them to exist outside the control of the government and central authorities. The term "cryptocurrency" also comes from the encryption technology used to protect the network

blockchain is an organization method to ensure the integrity of digital currency transaction data, and it is an important part of many cryptocurrencies. Many experts believe that blockchain and related technologies will subvert many instries, including finance and law. Cryptocurrencies have been criticized for many reasons, including their use for illegal activities, exchange rate fluctuations and the vulnerability of the infrastructure that underpins them. However, digital currency is also praised for its portability, divisibility, anti inflation and transparency

The contract transaction of digital currency is not safe. There are still many loopholes in the digital currency trading platform, for example, the most common ones are as follows:

1. Denial of service attack

denial of service attack is the most important attack against the digital currency trading platform at present. Through the denial of service attack, the attacker makes the trading platform unable to access normally, while the user cannot accurately distinguish the attack degree, It often leads to panic asset transfer, which brings some loss
