Digital purchasing and blockchain
1. digital currency facing 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< Another risk of digital currency is credit risk. Because there are middlemen in digital currency transactions, these middlemen are different from real organizations. In reality, organizations can be seen and felt, but the middlemen of digital currency are on the Internet, so the risk is greater
3. Digital currency has the characteristics of 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
investment is risky and business should be cautious

digital currency is illegal in China. In 2017, many ministries and commissions of the state have issued relevant issues, please search online
Relevant national leaders pointed out that blockchain technology is an important breakthrough for independent innovation of core technology. Therefore, more and more attention will be paid to the application of blockchain technology, and the central bank is also studying DCEP, but it is not clear when digital currency will enter the legal application -
a few countries, such as the United States, Japan and Singapore, are tolerant of digital currency:
1) the United States: there are usdt, ETH, and Libra in the future
2) Japan: in April 2017, Japan implemented the revised capital settlement law, stipulating that digital currency and Japanese yen are legal tender and can be traded with each other
3) Singapore: Singapore is tolerant of digital currency, and it has become a common practice for Singaporeans to invest in digital currency< br />
blockchain is a decentralized database, which is a series of data blocks generated by using cryptographic methods. This is a very big concept and has a wide application prospect
digital currency is an unregulated and digital currency. It is just an application of blockchain technology, which is based on the birth of blockchain technology
to put it simply, digital currency and blockchain are closely linked, and blockchain is the bottom technology and the most important technical means of digital currency. The most successful practice of blockchain is innovation in the field of currency.
at the same time, it can provide mutual trust for transactions by using trusted self-executive code, so as to rece uncertainty and promote digital transfer and asset transactions
bitcoin is the most well-known blockchain as an encryption currency that uses blockchain technology to realize alternative payment. Bitcoin is a kind of unlicensed blockchain, also known as public blockchain, which does not restrict the identity of users who consume bitcoin or participate in verifying the authenticity of transfer blocks in the blockchain (an energy intensive process, also known as "mining"). These miners get token, or bitcoin, in return, and given that everyone can view the block (though anonymously), the blockchain itself is somewhat transparent
bitcoin is controversial and banned by many countries e to user anonymity to a large extent. However, it is worth noting that the anonymity and energy use of bitcoin are its own characteristics, not the characteristics of the whole blockchain technology.
digital currency: bitcoin and other virtual currencies
Digital financial assets: Digital stocks, private equity, crowdfunding equity, bonds, hedge funds, all types of financial derivatives, such as futures, options and other financial assets
all kinds of digital assets: real estate, data assets, intellectual property, art, luxury, cultural heritage, enterprise assets, urban assets, etc.

The center is Yuzhong District. The core of Chongqing's main urban area, especially Jiefangbei Chaotianmen business district
the main urban area of Chongqing, which is called the metropolitan area in Chongqing's urban and rural master plan, covers an administrative area of 5472.68km2, including Yuzhong District, Dakou District, Jiangbei District, Nan'an District, Shapingba District, Jiulongpo District, Beibei District, Yubei district and Banan District. Metropolitan area is the core carrier of the National Central City and the political, economic, cultural, transportation and financial center of the whole city
Yuzhong District is the mother city of Chongqing and the seat of Chongqing municipal government. Shapingba District is the cultural and ecational District of Chongqing. Beibei District was the relocation area of Chongqing ring the period of the Republic of China. It was once the seat of the Executive Yuan and the presidential palace of the Republic of China. Banan District and Yubei district were originally Ba County and Jiangbei County, which are the mother counties of Chongqing. Their status is similar to Minhang District and Baoshan District in Shanghai or Fengtai District and Tongzhou District in Beijing
extended data:
at the beginning of its establishment in 1929, Chongqing's "city" area was 2.4 square kilometers. After more than 80 years of development, Chongqing's built-up area expanded more than 200 times. By the end of 2009, the built-up area of Chongqing's main city had reached 481 square kilometers
Since 1997, e to the special structure of Chongqing, the main urban area of Chongqing, which is similar to the concept of economic and cultural transportation of the municipality directly under the central government, has been formedthis concept is often associated with "old Chongqing area" (Chongqing City, Sichuan Province, commonly known as nine districts and twelve counties) and "Chongqing Municipality" (38 districts and counties in Chongqing), 95 square kilometers)
Since Chongqing became a municipality directly under the central government for the first time in 1939, the main urban area of Chongqing was the original administrative area of Chongqing in the Republic of China, which remained until the liberation From 1950 to 1980, Chongqing was first reced from a municipality directly under the central government to a city under separate planning, and then to a prefecture level city. Its administrative area expanded to the sum of the nine districts in the main city of Chongqing plus Changshou District, Qijiang district and Shuangqiao District (Note: Shuangqiao District was incorporated into Dazu District in 2011)since the 1980s, the cities separately listed in Chongqing's recovery plan, Jiangjin administrative Commissioner's office of Sichuan Province and eight counties in Yongchuan area (Jiangjin County, Bishan County, Yongchuan County, Hechuan County, Tongnan County, Tongliang County, Rongchang County, Dazu County) have been merged into Chongqing and become a part of Chongqing
The status of these counties in Chongqing is similar to that of Qingpu, Chongming and Jiading in Shanghai; Baodi and Jinghai in Tianjin or Miyun and Yanqing in Beijing are similar to Huangpi in Wuhan, Lin'an and Jiande in Hangzhou, Conghua and Zengcheng in Guangzhousource of reference: Internet - main urban area of Chongqing
if we compare the Internet digital platform with human beings: the Internet, mobile Internet and Internet of things are like the nervous system of human beings, big data is like the internal organs, skin and organs of human body, and cloud computing is equivalent to the backbone of human body. Without the network, the five zang organs and the backbone can not cooperate with each other; Without cloud computing, the viscera cannot be suspended; Without big data, cloud computing is a walking corpse. With the nervous system, spine, viscera, skin and organs, and the artificial intelligence equivalent to the soul - the human brain and nerve endings system, the basic "big wisdom cloud" platform has been formed. The blockchain technology, like the more advanced "genetic modification technology", greatly improves the brain reaction speed, bone strength and limb control flexibility from the basic level. With the help of the blockchain technology, the basic functions and applications of the Internet digital platform will be subversive transformed, which will have a stronger driving force for the economy and society< br />
why is the Internet digital platform so subversive? Research shows that there are "five full information features" in the "big smart mobile cloud" basic platform: full airspace, full process, full scene, full analysis and full value information
modern information-based instrial chain has all kinds of connections with the world through data storage, data calculation and data communication. It is the gene of this "five complete" feature that forms all kinds of information on the upper, middle and lower reaches of the instrial chain when it is combined with the instrial chain, and becomes a very valuable data resource
it can be said that any combination of traditional instry chain and digital "five complete" gene will immediately form a new mode of economic organization, which will have a subversive impact on traditional instries
in short, the modern Internet system under big data, cloud computing and artificial intelligence has a subversive effect. Today's Internet digital platform will further form the Wanlian system under the background of 5g, and the number of terminal connections will exceed hundreds and thousands of times than that of human mobile phones, tablets, laptops, etc. As a result, human Internet instry will develop from TOC type consumer Internet to tob type instrial Internet. In the era of digital economy driven by big data and other modern technologies, digital supply chain is the transformation trend of suppliers in various instries, which has become the consensus of many instries. Digital supply chain relies on cloud digital big data to achieve the effect of intelligent robot processing and application, and achieves the goal of global intelligent proction by digitizing things. Digital supply chain is the foundation of global, intelligent and flexible proction. It can realize c2m or B2B customization or mass proction through the platform. What are the characteristics of digital supply chain? What is the future development trend of digital supply chain< What are the characteristics of digital supply chain
digital supply chain is characterized by the supremacy of user experience. Through e-commerce platform, mobile terminal and other digital technologies, enterprises can save complex transaction links between businesses and customers, simplify transaction forms, save time, cost and energy of both sides, and ensure user experience. The digital supply chain platform can also go beyond the boundaries of time and region for real-time communication, negotiation and other interactive forms, which can not only enhance the experience, but also provide convenience for transactions
digital supply chain has excellent and reliable characteristics. Through digital technology, enterprises can understand real-time purchase, sales, inventory, distribution progress and other information, which is convenient for enterprises to manage procts and make clear and reasonable division of labor for employees. Suppliers can also use digital technology to monitor the dynamic proction, logistics process and proct quality in real time, standardize the behavior of employees, rece proct loss and waste, and build a reliable, efficient, low-cost and high-income operation and management system
the digital supply chain has the characteristics of active perception, and the digital platform contains a lot of information reserves, which can provide scientific and objective guidance suggestions for supplier decision-making. In the digital supply chain, cognitive technology and artificial intelligence can assist operators to perceive market demand and adjust business strategies, so as to enhance their competitiveness in the same instry. In addition, the establishment of an integrated supply chain mechanism and platform within the enterprise is of great significance to improve the overall operational efficiency of the supply chain
2. What is the future development trend of digital supply chain
at present, digital supply chain has a wide market and a large volume, and the information exchange in each link of the supply chain is not smooth, so it is urgent to integrate the digital supply chain and realize the effect of multi-party cooperation. The integration of digital supply chain is convenient for global suppliers to cooperate across the barriers of language and information asymmetry and rece the loss of cost. The integration of digital supply chain can also cooperate with upstream and downstream resources to achieve visual and intelligent management and control of the whole chain
it is one of the trends of the future development of digital supply chain that blockchain supports the construction of credible digital supply chain. Blockchain will play the role of infrastructure with cloud computing, big data and other technologies to help the construction of digital city. Regional chain technology has positive significance in technological innovation and instrial change, and it should be regarded as the breakthrough point of core technological innovation.
