1. 1. Low transaction cost
compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to a third party, and its transaction cost is lower, especially compared with cross-border payment which provides high service charges to payment service providers
2. Fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization, High anonymity
in addition to the point-to-point transaction without intermediary participation, one of the advantages of digital currency over other electronic payment methods is that it supports remote point-to-point payment, It doesn't need any trusted third party as an intermediary, and the two sides of the transaction can complete the transaction in a completely strange situation without mutual trust. Therefore, it has higher anonymity and can protect the privacy of traders, but it also creates convenience for cyber crime, which is easy to be used by money laundering and other criminal activities

2. How does the central bank set the minimum limit on the amount of money to be paid into an account? If you want to visit the official website of the people's Bank of China, you need to make an information inquiry
3. The central idea of digital currency is decentralization, but the central bank should only use the encryption method of digital currency.
4. It is reported that the central bank's research on the issue of digital currency is not a temporary move. Since 2014, the research on the central bank's digital currency has been carried out for five years. In 2017, the digital currency Research Institute of the people's Bank of China was officially established, and has applied for more than 70 patents related to digital currency technology< In recent years, with the development of Internet technology, especially blockchain technology, many so-called "virtual currencies" have emerged in the world, such as bitcoin and Laite currency, which are controversial in recent years. So, how is the digital currency proposed by the central bank different from these commercial "virtual currencies"? The following is an analysis of the patent of Xiaoju
some patents of the digital currency Research Institute of the people's Bank of China (data source: huijuyun)
what is digital currency? --[ Invention patent] digital currency system
cloud computing is the mainstream direction of the future back-end server, and the digital currency back-end system adopts cloud based solutions
in e-commerce activities, e to different roles, the requirements for digital currency are different: customers require digital currency to be easy to use, safe to store and anonymous; Businesses require digital currency to be certifiable and can be converted into real currency; Banks require that digital currency cannot be illegally used or forged. Therefore, digital currency d-rmb should have the following characteristics:
1. Security: it can prevent any party in business from changing or illegally using digital currency< 2. Non repeated spending: digital currency can only be used once, and repeated spending can be easily detected
3. Controllable anonymity: banks and businesses collude with each other and can't track the use of digital currency, which requires that the system can't link the purchase behavior of e-cash users, so as to conceal the purchase history of digital currency users, but the issuer of digital currency can track the use of digital currency
4. Unforgeability: digital currency that users cannot fake
5. Fairness: the payment process is fair, which ensures that either the two parties succeed in the transaction, or both parties have no losses, so as to prevent one of the parties from suffering losses in the transaction
6. Compatibility: the issue process and circulation of digital currency in d-rmb system should refer to the issue and circulation of physical currency as far as possible
as for digital currency, it should be able to adapt to various use scenarios of existing currency and be freely convertible with existing currency
this patent provides a digital currency system, including central bank digital currency system, commercial bank digital currency system, and authentication system
among them, the central bank's digital currency system is used to generate and issue digital currency, and to register the ownership of digital currency; The digital currency system of commercial banks is used to perform banking functions for digital currency; The authentication system is used to provide authentication for the interaction between the central bank digital currency system and the terminal equipment used by the users of the digital currency, and for the interaction between the central bank digital currency system and the commercial bank digital currency system
schematic diagram of the basic structure of the digital currency system
to achieve a convenient and safe digital currency system, and can be applied to a variety of application scenarios of digital currency in reality< How to convert digital currency into cash[ Invention patent] method and system for converting digital currency into physical cash, The digital currency system of the commercial bank sends the digital currency to the central bank digital currency system, the central bank digital currency system generates a one-time withdrawal code, and then sends it to the user terminal equipment for presentation to the user, and changes the owner information of the digital currency from the user to the central bank
the digital currency system of the commercial bank sends the one-time withdrawal code provided by the user to the digital currency system of the central bank. The digital currency system of the central bank confirms that the one-time withdrawal code is valid, and then increases the cash amount of the commercial bank account, and sends a notice to the digital currency system of the commercial bank that the one-time withdrawal code is valid, After receiving the notice, the digital currency system of commercial banks issues a contribution instruction, in which the contribution instruction is used to control the machine or prompt the user to pay the cash whose amount is equal to the cashed amount manually<

How can digital currency be consumed online? --[ Invention patent] method and system of online payment using digital currency chip card
this patent is a method and system of online payment using digital currency chip card. A method for online payment using digital currency chip card is provided. The method includes: a user terminal device sends payment information to an acceptance terminal device, and the payment information includes digital currency chip card information and digital currency equivalent to the payment amount; After receiving the payment information, the receiving terminal sends the payment information to the digital currency system of the commercial bank; After receiving the payment information, the digital currency system of the commercial bank sends a request to change the owner to the digital currency system of the central bank; The central bank digital currency system changes the owner of the digital currency to the merchant's commercial bank code after receiving the request to change the owner; The digital currency system of commercial banks changes the account amount of merchants<
the method flow chart of online payment with digital currency chip card in recent years, the commercial virtual currency has been controversial, and more and more people realize that the future development trend of digital currency is legal digital currency issued by central banks based on national credit. At present, China is still in the stage of accelerating the research and development of digital currency. For example, the central bank held a working video conference in the second half of 2019 on August 2, calling for "accelerating the pace of research and development of China's legal digital currency". Recently, the "opinions of the CPC Central Committee and the State Council on supporting Shenzhen to build a leading demonstration zone of socialism with Chinese characteristics" clearly stated that "We support the development of innovative applications such as digital currency research and mobile payment in Shenzhen". Let's wait and see when digital currency will meet you.
