Four pilot projects of blockchain
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
some areas where blockchain can be used can be as follows:
& ᦇ 9642; Smart contract; Securities trading; E-commerce; Internet of things; Social communication; File storage; Proof of existence; Authentication
&9642; Equity crowdfunding
we can compare the development of blockchain with the development of the Internet itself. In the future, something called finance Internet will be formed on the Internet. This thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chain and instry chain (LAN), bitcoin series starts from public chain (WAN), They all express the same concept - digital asset, and finally converge to an intermediate equilibrium point
The evolution mode ofblockchain is as follows:
& 9642; Blockchain 1.0 digital currency; Blockchain 2.0 digital assets and smart contracts; Blockchain 3.0: implementation of distributed applications in various instries
Hello, where are the first batch of pilot cities of the central bank's digital currency? Do you think they are well deserved super first tier cities "Beijing, Shanghai, Guangzhou and Shenzhen"? I want to tell you that it's not all right. Except Shenzhen, the other three cities are Cheng, Suzhou and xiong'an new area. At present, Shenzhen is the earliest city to launch digital currency. On October 9, Shenzhen issued 10 million digital currency. 50000 people, 200 yuan per person, can enjoy the welfare, which is distributed to everyone free of charge through the way of wagging number. Here, I can only envy you. The implementation of digital currency is so fast. The friends in the pilot cities are lucky. I just want to watch you win the lottery
the first batch of pilot cities are selected in these four cities, which is the first step for digital currency to go to the whole country. When it matures in the future, it will be promoted to more pilot cities. So don't worry, just wait. Even if our city is not a pilot, it doesn't matter. Next time it will be our city. The pilot is just to test the stability of the system, and we don't have a great chance to get the red envelope of digital currency. There are so many people in Shenzhen, and only 50000 numbers are selected. Here we would like to express our support and thanks to the cities selected as the pilot cities of digital currency
Shenzhen became the first pilot city of blockchain electronic invoice in China, and Tencent provided technical support
by using blockchain electronic invoice, enterprises can apply for, issue, check and enter invoices on blockchain. Users can store, transfer and reimbursement on the chain. Cai Yige, general manager of Tencent's blockchain business, said that the blockchain electronic invoice optimizes the whole process of billing and reimbursement, realizing the seamless link between consumption scenarios and tax services
it's more and more convenient, and the progress of science and technology makes everyone enjoy the dividend

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.
According to the general office of the Ministry of housing and urban rural development, it has decided to carry out green construction pilot work in Hunan Province, Shenzhen city of Guangdong Province and Changzhou City of Jiangsu Province. The pilot areas should vigorously promote the integrated application of BIM Technology in the design, proction and construction stages of pilot projects, and take 5g, Internet of things, blockchain, artificial intelligence and other technologies as the support to promote the application of intelligent equipment and equipment such as intelligent construction sites and construction robots, so as to realize the traceability of project quality, improve project quality and management efficiency, and enhance the level of construction informatization. With the continuous development of information technology, the world has officially entered the digital era. In the digital wave, more and more enterprises join the team of digital transformation. How to effectively protect data security will become the core competitiveness of this era
blockchain has the advantages of decentralization, distributed accounting, encryption and traceability, which can ensure the integrity and authenticity of the data on the chain. Once it is tampered or forged, it can be found. At the same time, because the blockchain has the characteristics of Distributed Accounting, even if the data on indivial nodes are deleted, other nodes can still save the data completely, ensuring the normal operation of the whole blockchain storage system. Based on the above advantages, blockchain is naturally suitable for electronic data storage. The introction of blockchain can effectively solve the authenticity and legitimacy of electronic evidence and make the process of electronic data storage more reliable
since the national development and Reform Commission incorporated the blockchain into the new infrastructure, the whole country has ushered in the upsurge of blockchain policy. The central and local governments have promulgated blockchain related policies one after another, taking the blockchain as the main breakthrough in the field of new economy and technology, building the future strategic competitive advantage, and the related application scenarios of blockchain are hot. The deep integration of blockchain and instry is the embodiment of maximizing the use of blockchain< since 2014, easysaving has begun to deepen the research and development of underlying technology and application innovation of blockchain from the perspective of instry. Based on the electronic data preservation of blockchain, easysaving has launched a number of brands such as Junzi signature in the field of blockchain electronic signing, micro right in the field of blockchain intellectual property protection, and zhongzhengbao in the field of blockchain Internet justice
in recent years, remarkable achievements have been made in the cultivation and innovative application of urban block chain instry in China. First of all, the development of instrial agglomeration has been accelerated. Chongqing urban block chain instrial park has signed contracts to settle more than 60 well-known enterprises such as Qulian, Dicken, jinwowo and Langchao cloud chain, and the instrial agglomeration area has initially formed. In the blockchain application demonstration, there are also many bright spots. China's first blockchain government service platform was launched in Chongqing, and the first electronic business license based on blockchain technology was issued. The super node of "spark chain network" was settled in Chongqing, and the system of "blockchain + judicature + electronic data storage" was awarded the instrial Internet pilot demonstration project of MIIT
according to the introction of the person in charge of the network information office of the municipal Party committee, ring the "fourteenth five year plan", our city will make efforts in four aspects, vigorously promote the development and management of the blockchain instry to a new level, and inject new momentum into the construction of our city as an "intelligent city" and "intelligent city"
in terms of instrial ecosystem, our city will focus on major scientific frontier issues of blockchain, plan to promote a number of major projects of technology application and instrial development, and build a complete instrial ecosystem of blockchain. For example, the Municipal Economic and Information Commission will support key blockchain enterprises in tackling key core technologies. The municipal big data Development Bureau will push the city's blockchain instry into the fast lane with high standards
in terms of instrial layout, we will rely on Yuzhong District and Liangjiang New District to attract a group of blockchain enterprises with strong innovation ability and great development potential to set up R & D centers and enterprise headquarters. Relying on high tech Zone and Western (Chongqing) Science City, Cheng Chongqing blockchain science and technology innovation corridor will be built to promote the pilot application of "blockchain + professional fields" in all districts and counties
in terms of independent innovation, efforts will be made to improve the continuous innovation ability of blockchain technology, and build an open, inclusive and dynamic blockchain innovation environment. For example, the Municipal Bureau of science and technology will continue to strengthen scientific and technological support and promote the establishment of blockchain innovation service institutions. Yubei District will strengthen government planning and guide market players to transform from "Internet thinking" to "blockchain thinking"
in terms of integrated application development, our city will focus on promoting the deep integration of blockchain and real economy, deep application in the financial field, and wide application in the field of public services and people's livelihood. For example, the municipal agricultural and Rural Committee will accelerate the innovative development of blockchain + smart agriculture, and boost the high-quality development of digital agriculture in the city. Chongqing Business Management Department of the people's Bank of China will explore more pilot application scenarios to serve cross-border settlement and investment and financing facilitation.
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
