The difference between Tencent and ant xiongan digital currency
the three party payment tools such as digital currency and Alipay and WeChat payment are different. The payment of Alipay and WeChat is a well-known third party payment tool in China. Digital money is also possible in theory, but the market share of digital money in the field of payment is still very low.
1、 Different monetary attributes
1. Digital currency:
digital currency belongs to legal tender
2. Wechat:
wechat belongs to the third-party payment instrument
3, Alipay:
Alipay belongs to the third party payment tool. p>
2. Different issuers
1. Digital currency:
the issuer of digital currency is the central bank
2. Wechat:
the clearing Party of wechat is a commercial bank
3, Alipay:
Alipay's settlement party is commercial bank. p>
extended data
in the third-party payment mode, the buyer uses the account provided by the third-party platform to pay for the goods (to the third party), and the third party notifies the seller of the arrival of the goods and requires delivery; After receiving the goods, inspecting the goods and confirming, the buyer shall notify the third party for payment; The third party transfers the money to the seller's account
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:
1. Due to some open algorithms, digital currency has no issuing subject, so no one or organization can control its issuing
Because the number of algorithm solutions is determined, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency3. Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough
digital money is getting closer and closer. Many people will wonder whether digital money will completely replace cash or completely replace WeChat and Alipay mobile payment? What are the differences between digital money and WeChat or Alipay payment? The following is an analysis
digital money and WeChat Alipay payment. Although they all belong to mobile payment, the two payment methods are very similar. P>
WeChat or Alipay payment
WeChat Alipay payment has become the most commonly used payment. We just take out the mobile phone and open the WeChat or Alipay scan payment code, so that we can do business and shop without cash at all. P>
, but WeChat or Alipay payment is based on the premise that the mobile phone must have signals, but also have the premise of the network. Similar to the current p>
, although there are many ways to pay, similar to some elderly people, or cheap mountain areas, WeChat and Alipay temporarily use difficulties, or need to use cash to achieve a transaction. p>
but after the digital currency comes out, these difficulties can be solved. The elderly and remote mountainous areas can also use digital currency, so they can say goodbye to cash
comprehensive analysis shows that digital money is an upgraded version of WeChat and Alipay mobile payment. Since it is an upgraded version, and it is issued by the central bank, it naturally has its own advantages. WeChat and Alipay do not have these advantages. As long as there are differences between the advantages and disadvantages, there is definitely a difference between the two. The above three points are the biggest difference between them. p>
In early 2014, the Central Bank of China set up a special research group on legal digital currency to demonstrate the feasibility of issuing legal digital currency by the central bank. On January 29, 2017, the central bank officially established the digital currency Research Institute. After the successful development of the prototype of legal digital currency, the digital currency Research Institute of the people's Bank of China has tried to deploy institutions in many parts of the country, and through the integration with R & D institutions and instries, it has achieved the research results of financial development technology. In 2018, the digital currency Research Institute of the people's Bank of China successively settled in Nanjing and Shenzhen. In 2019, the people's Bank of China announced that digital currency will be piloted in Shenzhen, Suzhou, Cheng and xiong'an

Institute of computer science, University of national defense science and technology -
Yinhe - Ⅰ's computing speed was 100 million times per second in 1983
Yinhe - Ⅱ's computing speed was 1 billion times per second in 1994
Yinhe - Ⅲ's computing speed was 13 billion times per second in 1997
Yinhe - Ⅳ's computing speed was 1 trillion times per second in 2000
Yinhe - Ⅴ's computing speed in research was 1 trillion times per second? Billion times (military) on November 19, 1992, the "Galaxy II" 1 billion times supercomputer developed by the University of Defense Science and technology passed the national appraisal in Changsha
it has realized the leap from vector supercomputer to parallel supercomputer, becoming the third country to realize 1 billion times supercomputer after the United States and Japan. In 1994, Yinhe II supercomputer was officially put into operation in the National Meteorological Administration for medium range weather forecast. On June 19, 1997, the "Yinhe III" parallel supercomputer developed by the University of national defense science and technology passed the national appraisal in Beijing. The machine adopts distributed shared memory structure, which is oriented to large-scale scientific and Engineering Computing and large-scale data processing. The basic word length is 64 bits, and the peak performance is 13 billion times. The machine has a number of leading technologies in China, and the comprehensive technology has reached the current international advanced level< At present, only a few developed countries have mastered the development technology of high-performance supercomputers“ The successful development of the "galaxy-iii" supercomputer has enabled China to step into the world's advanced ranks in this field
in March 1994, in the fierce market competition, "Galaxy III" was officially established. In June 1997, it took more than three years to successfully develop the "Galaxy III" 10 billion times supercomputer whose system integration technology reached the international advanced level at that time, realizing the leap from multiprocessing parallel supercomputer to large-scale parallel processing supercomputer
in 2000, Galaxy IV supercomputer with 1024 CPUs came out, and its peak performance reached 1.0647 trillion floating-point operations per second. All its indicators reached the international advanced level at that time, which brought the development level of high-end computer system in China to a new level
"galaxy" series supercomputers are now widely used in weather forecasting, aerodynamic experiments, engineering physics, oil exploration, seismic data processing and other fields, resulting in huge economic and social benefits. The National Meteorological Center has used the "Yinhe" supercomputer in the medium range numerical weather forecast system, making China one of the few countries in the world that can issue 5-7-day medium range numerical weather forecast
