Blockchain digital migration 2020
Anti counterfeiting, such as frog coin and Weilian the source and process of frozen food monitoring of final procts such as imported milk powder and luxury goods: red wine, bags and refrigerators, because it is impossible to cheat by writing into the blockchain Back modification is being implemented or has been implemented (only the chain's partners are very strong)
smart contract or intellectual property rights, such as publishing a song. In the blockchain, you own the song, use the smart contract to sell and protect the property rights, such as Neo and Ethereum. Game development or program development: for example, cryptokitties are free to breed and trade different kinds of cats without age or rarity (the closer the age is, the more expensive it is)
the evolutionary version of ICO IPO raised $40 billion in 2017, which is the securities of any company or indivial to support its development of e-money Platform (polymeth)
free trade of game items under development
Because the blockchain technology is not mature at this stage, and the infrastructure is not perfect, many applications are limited, and the overall application is still in a very early stage
First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database. Secondly, anyone can set up a server and join the blockchain network to become a node. In the world of blockchain, there is no central node (decentralization). Every node is equal and keeps the whole database. You can write / read data to any node, because all nodes will be synchronized in the end to ensure the consistency of the blockchainp l e a s e d o n o t t a k e m y s u n s h i n e a w a y

the book "blockchain: blueprint and guide to the new economy" (New Star Press, January 2016), written by Melanie Swann, founder of blockchain Science Research Institute, points out that blockchain plays the same role in trust as the Internet in information. Like the early Internet, blockchain has the potential to innovate everything, and blockchain is the source of power for the fourth generation of instrial revolution. Melanie also constructively proposed the possibility of using blockchain to automatically track all digital behaviors and create a decentralized digital information base for identity verification, so as to provide services traditionally provided at the national level with lower cost and more efficiency
at present, international giants such as Microsoft, Tencent, Wanda, Goldman Sachs, JPMorgan Chase and Dell are all testing blockchain projects, and small and micro enterprises such as European crowdfunding have become the first to eat crabs.
the favorable development prospect of blockchain will drive the overall rise of a shares and become the focus of investment institutions. The rapid development of blockchain will bring new changes to the global personal payment mode, Global trade settlement system, global currency issuance mechanism, and improve the operation efficiency of instrial chain
I. The personal payment method has been subvertedthe future development prospect of blockchain will be connected with global commercial banks and Payment institutions to solve the multi-party communication in cross-border remittance, participate in the transmission of documents and newspapers, and realize the cross regional and cross time synchronous coordination and processing of all parties' information, which can greatly improve our original serial processing among institutions, Efficient processing of global personal payments{ RRRRR}
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
