Yu Jianing MIIT blockchain

1. The explanation of MIIT is as follows: blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing paradigm to program and manipulate data by using smart contracts composed of automated script code
take an example: for example, Sun Tzu asked Li Zi to borrow 100 yuan, but Li Zi was afraid that he would default, so he asked the village head for notarization and added the account. This is called centralization. But if you don't ask the head of the village, you can shout "I'll lend my grandson 100 yuan! Please put it in the account book. "This is called decentralization
in addition, you can refer to bitcoin, the representative proct of blockchain

2. Blockchain Technology Application Research Center is an institution directly under the blockchain Technology Application Research Institute.
the blockchain Technology Application Research Institute was established in Zhengzhou City, Henan Province under the policy guidance of the Ministry of Commerce, the Ministry of instry and information technology and the Ministry of science and technology.
initiated by the SME Development Promotion Association, it is a well-known professional analyst, the most authoritative blockchain research expert in China, and an expert professor in Colleges and universities, CEOs of well-known enterprises participate in
research institutes that provide Zhongyuan enterprises with blockchain technology landing solutions. It is the first and the only third-party technology research institution established in China to study the communication and service blockchain technology
based on the working principles of authority, standardization, systematicness, openness and public welfare, the blockchain Technology Application Research Institute assists the government in formulating the instry supervision mechanism and assisting the government in promoting landing solutions. It aims to provide Zhongyuan enterprises with the research and promotion of blockchain technology landing scheme, popularize and enhance the concept and awareness of the majority of enterprises for blockchain technology, play a guiding role in the development of Zhongyuan, promote the healthy and orderly development of Zhongyuan blockchain technology, and help the economic rise of Zhongyuan
the blockchain Technology Application Research Institute will support 1000 Central Plains enterprises to implement blockchain technology application within two years by docking with one billion capital resources, so as to help the Central Plains economy to overtake.

3. AOS is a public chain of privacy, ETH is a comprehensive public chain of smart contracts, and the track is different. However, God V said that privacy features should be added to eth in the summer of 2020. If we compare this point, it is still possible

Why do we say that eth ecology is complex? If we want to fully deploy privacy, it will be difficult in a short time. However, as a new public chain, AOS can quickly deploy its functions, so it is entirely possible for AOS to surpass eth in privacy.

5. You are content with it, so good units also dislike this dislike that, you know how many people live less than you. This is the leader's idea. It's useless for you to apply to anyone, and it's not good for you. You should see the right time to speak, and don't come out on your own.

6. Bitcoin is a kind of network virtual currency, which can buy real-life goods

it is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals

in 2013, the US government recognized the legal status of bitcoin, which led to a sharp rise in the price of bitcoin. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan

7.

In the Internet age, the birth of every new thing will make people think. Understanding what blockchain is is the premise of all expectations, queries and discussions

-- it is difficult to tamper with. The blocks on the blockchain are closely linked, and each block will correspond to a long string of function passwords. If the content of a block is modified, the subsequent block content will no longer match, resulting in information tampering and invalidation, which greatly improves the integrity and authenticity of information on the network. Some people in the instry call the difficulty of tampering with information on the blockchain "finding a grain of sand in all the sand on the earth."

-- decentralization. Compared with the traditional way, blockchain can realize the automatic operation of a system without the management of the central organization“ Two strangers can reach trust quickly and cheaply without relying on the third-party intermediary, and then realize the direct and efficient point-to-point transaction. " Yu Jianing, director of the Instrial Economy Research Institute of the information center of the Ministry of instry and information technology, said

for example, online shopping goods now need a third-party payment platform in the payment link. If it is under the blockchain application, sellers and buyers can realize direct transactions under the trust mechanism

8. Bus routes: South extension of Metro Line 1 → Metro Line 2, the whole journey is about 30.7 km
1. Take South extension of Metro Line 1 from Nanjing South Station, pass 8 stops, and reach Xinjiekou station
2. Take Metro Line 2, pass 12 stops, and reach Xianlin central station
3. Walk about 810 meters, After arriving at Xianlin School of Nanjing University of Posts and telecommunications, you can see the picture of the building This data comes from the network map, and the final result is subject to the latest data of the network map
