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

public chain is a highly "public" blockchain, anyone can freely participate in the network
example of terminology usage
as an infrastructure project for mediating data exchange between blockchains, a mechanism for data exchange on public blockchains will be established
detailed description
in the blockchain used to record the transaction information of encrypted assets (virtual currency), this is a mechanism used by an unspecified number of participants to establish transaction information by consensus without a specific management entity. It is very safe to prevent forgery of transaction information, but it requires a lot of calculation, so its disadvantage is that it takes a long time to complete the transaction when there are many participants
7. Scalabilityscalability refers to the scalability of delayed transaction processing
examples of terminology usage
soaring gasoline prices highlight Ethereum's scalability issues
detailed description
e to the nature of blockchain and the limited amount of transaction data that can be written in a block, the processing is delayed. Remittances can take a long time, which can lead to higher transaction costs. bitcoin is the first cryptocurrency born, which has been considered as a special problem, but efforts to solve this problem have been implemented, such as using other technologies such as lightning network and developing new blockchain
8. Gas costgas cost is the (Network) transaction cost on Ethereum blockchain
examples of terminology usage
this week, on the Ethereum blockchain, although there are a small amount of remittances, there are still many cases of high natural gas bills being paid

9. Liquidity mining (liquidity mining)considering the provision of liquidity (currency pair), liquidity mining is to grant governance token in addition to interest, so as to attract those who implement the rate of return balance
examples of terminology usage
detailed description
in liquidity mining, by storing specific assets in the liquidity pool and providing liquidity that traders can buy and sell, the swap fee at that time can be obtained as income. These liquidity mining originated from the largest decentralized exchange "uniswap", and many liquidity mining contracts were born, such as curve finance and balancer
10. Defi (distributed Finance)defi (decentralized Finance) refers to the financial services or systems that use blockchain and provide without a central administrator
examples of terminology usage
since June 2020, the market of defi has developed rapidly
specify the abbreviation of "decentralized finance". The financial services offered by defi include the issuance of stable coins, lending currency and cryptocurrency exchanges. Many platforms use Ethereum blockchain
11. POS (proof of equity)POS is a consensus algorithm, which allows you to approve and generate new block rights according to the percentage (equity) of your own virtual currency
According to vitalik buterin, co-founder of Ethereum, migrating eth's consensus algorithm from POW to POS will improve security and scalabilityspecify the abbreviation of
proof of interest. We can also consider the holding period of virtual currency. It was born as an alternative to the "proof of work (POW)" consensus algorithm, which requires high-performance computers to approve transactions and consumes a lot of energy. If approved, you can receive a new virtual currency as a reward
12. DappsDAPP is an application developed with open source blockchain
