Late October 2019，The blockchain industry has officially become a national strategy。April 21, 2020，Blockchain has been officially included in the scope of “new infrastructure” by the National Development and Reform Commission。The People's Bank of China announced in Shenzhen at the same time、Chengdu、Suzhou、Xiongan New Area and future Winter Olympics scenarios launch internal closed pilot testing of digital bet365 withdrawal (DC/EP) using digital bet365 withdrawal wallets as carriers，my country is expected to become the first country in the world to issue digital bet365 withdrawal。New infrastructure、The rapid development of blockchain and digital bet365 withdrawal injects new momentum into economic recovery，Promote the digitalization of our country’s social and economic structure、Adjustment, transformation and upgrading of informatization and intelligence，But at the same time, it increases the complexity of our country’s financial activities。

　Focus on preventing and resolving bet365 withdrawal risks

This year is the final year for the battle to prevent and resolve financial risks，May 22，Clearly stated in the government work report，Risks have accumulated in financial and other fields，Effective prevention and control of major financial risks is still one of the current goals。Under the global warming trend of digital bet365 withdrawal，We should focus on systemic financial risks and overall financial risks under the new economic background。

Information security risks of blockchain。Blockchain-based central bank digital bet365 withdrawal as a bet365 withdrawal symbol，its issuance、Circulation、All aspects such as withdrawals must be implemented based on the Internet，Secure storage of digital currencies、Safe Transaction、Put forward extremely high requirements in all aspects of safe circulation。However, there are still a series of risks and hidden dangers in the current security of blockchain information technology。First, there is a conflict between openness and restricted access in the blockchain。Compared with traditional technology，Although blockchain technology relies on decentralization、Features such as anti-tampering and high transparency greatly improve the security of financial transaction systems，But it is still impossible to restrict data access rights。Transaction data included on the blockchain、All information including signature information，Can be freely accessed on the same chain，Unable to achieve beneficial protection of personal privacy information data and security。Second, there are underlying security vulnerabilities in the blockchain that have not yet been overcome。Once a hacker attacks and steals the public’s private key code information，can control the blockchain system，Posing a threat to the public’s personal financial security。At the same time，The central bank provides digital bet365 withdrawal services based on cloud servers，In blockchain mode，After a node is connected to the network，Establishing connections with other nodes，The decentralized characteristics of blockchain，Enable each node to have equal rights to publish broadcast information to confirm transaction validity。Any link is compromised，Both will lead to the overall collapse of blockchain-based digital currencies。Third, blockchain transaction security capabilities need to be improved。Since digital currencies are mainly used in high-frequency retail business scenarios，Put higher requirements on digital bet365 withdrawal transaction processing capabilities，In particular, it is required to have the security capability to support the high concurrent transaction needs caused by shopping carnivals such as "6·18", "Double 11" and "Double 12"，But the current blockchain-related technology is not yet mature。

Legal regulatory risks of digital bet365 withdrawal。Currently, our country urgently needs to build a relevant legal system for digital bet365 withdrawal，Issuance of digital bet365 withdrawal、Provide adequate legal support for circulation and supervision。Compared to traditional currencies，Difficulties in defining the transfer of ownership of digital currencies，Plus the digitization of digital bet365 withdrawal、Anonymity、Dynamic transfer and other features，The bet365 withdrawal circulation process is no longer based on the bet365 withdrawal itself but transformed into based on transaction facts，There is no actual transfer of bet365 withdrawal either，Only presented as continuous transaction record changes，Once lost, it is difficult to retrieve，And the protection of the rights and interests of digital bet365 withdrawal holders needs to be strengthened。

Reasonable monitoring risks of digital bet365 withdrawal。There are currently practical difficulties in real-time and effective supervision of digital currencies，Posing a threat to the security of the financial system。One，Digital bet365 withdrawal has the essence of de-mediation，Potentially encountered malicious tampering during the production and circulation process、Fake、Risk of duplication。In view of the special bet365 withdrawal form of digital bet365 withdrawal，Its risk prevention is different from traditional currencies。Part 2，Due to the portability of digital bet365 withdrawal、Anonymity and transnational circulation，There are potential financial security risks of money laundering and cross-border capital arbitrage。In view of the point-to-point transaction settlement nature of digital bet365 withdrawal，The existing anti-money laundering financial supervision division of labor system needs to be further improved，And exert its effectiveness reasonably and effectively。

Financial policy dilemma under digital bet365 withdrawal。First, digital bet365 withdrawal brings risks and challenges to the existing financial system。Issuance of central bank digital bet365 withdrawal，It will bring about changes in the flow of social deposits，Transfer from financial institution to central bank。The cash leakage rate of commercial banks increased，Deposit creation coefficient shrinks，Loss of money creation function at M2 level，Resulting in reduced M2 liquidity，Intensifying the risk of financial disintermediation。Second, digital bet365 withdrawal makes it more difficult to formulate financial policies。my country’s digital bet365 withdrawal issuance adopts the “central bank-commercial institution acting as an agent” two-tier investment model，Digital bet365 withdrawal enters the circulation system，Will amplify the spillover effects of monetary policy，Causing systemic risks such as over-delivery。If the digital bet365 withdrawal is issued too much, it will cause the digital bet365 withdrawal to depreciate，Inducing price increases in the real world，More challenges to existing monetary policy making。

　　Keep the bottom line Achieve three-dimensional prevention and control

With the advancement of digital bet365 withdrawal，Financial security issues under blockchain conditions require us to take measures at multiple levels，Resolutely hold on to the bottom line，Achieve three-dimensional prevention and control。

Attaching great importance to information technology research and development。Technical risk management is the primary risk prevention area for digital currencies under the blockchain。First，Basic technology and rule arrangements should be chosen carefully，Strictly formulate trading rules、Decision-making arrangements and other aspects，After a period of stable operation and demonstration, digital bet365 withdrawal will be officially introduced to society。Second，Should be based on information security、Data Security、Transaction security、Terminal security and other multiple angles，Increase blockchain、Research and development efforts in digital bet365 withdrawal encryption technology and other information technology fields，Accelerate technology upgrade，At the same time, we conduct top-level design of information system construction based on the current "dual-layer architecture" of legal digital bet365 withdrawal。Third，Learning from Bitcoin’s asymmetric encryption technology application，And build on it，Progressively improve the system scalability of my country’s blockchain digital bet365 withdrawal，Gradually extend practical application scenarios。Fourth，Increase investment in human resources in information technology-related fields。Encourage the cultivation of information technology talents，Support blockchain R&D investment and subject research by universities and large high-tech enterprises。Fifth，Purify the network environment，Prevent financial security risks in blockchain scenarios。

Improve the legal system supporting digital bet365 withdrawal。First，Make a standardized definition of the nature and impact of digital bet365 withdrawal，Introduction of laws and regulations on digital bet365 withdrawal management，Clearly define the legal status of digital bet365 withdrawal，Build a complete legal protection system for issuance and circulation，Provide legal support for the legal compensation and ownership transfer of digital bet365 withdrawal。Secondly，Improve the access and management of digital bet365 withdrawal issuers，Clear the method of digital bet365 withdrawal issuance，Constructing anti-counterfeit bet365 withdrawal、Anti-Money Laundering、Anti-fraud and other legal supervision systems。Finally，Blockchain and digital bet365 withdrawal are both emerging fields，Development has multiple possibilities and complexity，We should promptly learn from the design framework and issuance mechanism of other countries’ central bank digital currencies and the legislative guarantee system，Make timely adjustments based on actual conditions、Revised and Improved。

Build a reasonable regulatory system for digital bet365 withdrawal。Digital bet365 withdrawal is different from traditional bet365 withdrawal，It is necessary to further improve the existing regulatory system to prevent various potential risks，Improve financial security。First, it is necessary to build a modern and standardized financial regulatory framework。The second is to follow certain procedures，Develop an information disclosure system in the field of digital bet365 withdrawal transactions。The third is to adopt open supervision methods。On the basis of accurately identifying risk points，Flexibly respond to potential risks in the issuance and circulation of digital bet365 withdrawal，Building a benign digital bet365 withdrawal circulation environment。The fourth is to open up and welcome the new business model conceived by digital bet365 withdrawal，And conduct reasonable supervision in a timely manner，Prevent and resolve systemic risks。The fifth is to “use chain to control chain” to achieve effective supervision of digital bet365 withdrawal。Building a blockchain-based regulatory system through regulatory technology，Promote the “Blockchain+” supervision mechanism。Sixth is to deepen international regulatory cooperation on digital bet365 withdrawal。

In-depth study of the impact of digital bet365 withdrawal policy。First, ensure the effectiveness of the current monetary policy transmission。Actively research the rules of digital bet365 withdrawal issuance and circulation、Basic issues of digital bet365 withdrawal such as business operation architecture，And based on in-depth investigation and research on the important impact of digital bet365 withdrawal issuance on the current monetary system and financial system，Strictly demonstrate the path and mechanism for the implementation of the digital bet365 withdrawal system。The second is to reduce the risks that digital bet365 withdrawal brings to the security of the existing financial system。The reason why money has the function of a means of circulation，Because money is the independent value of commodities。Digital bet365 withdrawal is essentially an encrypted string with value characteristics，Only replaces the circulating metal bet365 withdrawal to perform the function of a means of circulation，The issuance of digital bet365 withdrawal should also be limited to the metal bet365 withdrawal needed in circulation。Monitoring and analyzing the money creation mechanism of digital bet365 withdrawal、After the policy transmission mechanism and the crowding out effect on traditional bet365 withdrawal，The central bank should flexibly operate multiple policy tools，Ensuring the effectiveness of the current monetary policy transmission under the digital bet365 withdrawal system。At the same time，Properly utilize the current dual-layer architecture of legal digital currencies based on the hierarchical use of accounts and wallets，Divide levels with commercial banks，Building a benign operating mechanism。

With 5G、Internet、Artificial Intelligence、Blockchain、The development of bet365 withdrawal innovation models brought by big data，bet365 withdrawal innovation and bet365 withdrawal security as a pair of contradictions，Continuously performing conflicts and integration on a global scale，We must integrate into the virtual real world with an open mind，Understanding unrealistic circulation media，Create my country’s stable and harmonious bet365 withdrawal security system with a correct attitude。
