Central blockchain

1.

We need to establish data layer, network layer, consensus layer, incentive layer, contract layer and application layer

1. The data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and time stamp

2. The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism

The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes

The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuing mechanism and distribution mechanism of economic incentives

5. The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain

6. The application layer encapsulates various application scenarios and cases of blockchain

, general secretary of the CPC Central Committee, stressed in the eighteenth collective learning of the Central Political Bureau, "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". <

the forward-looking judgment of the CPC Central Committee has brought the "blockchain" into the public view and become the common focus of financial capital, real economy and public opinion

from network power to big data, from media integration to blockchain, the Politburo of the CPC Central Committee has collectively studied and aimed at the forefront of technological change, showing the direction, foresight and foresight of the CPC Central Committee, leading the pace of China's instrial change and economic transformation. This collective study of the Political Bureau of the Central Committee of the CPC, with special emphasis on "blockchain", has opened up an imaginary space for the development and application of blockchain

from the perspective of science and technology, blockchain involves many scientific and technological issues such as mathematics, cryptography, Internet and computer programming. From the perspective of application, in short, blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent

these features ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the fact that blockchain can solve the problem of information asymmetry, and realize the cooperative trust and concerted action among multiple agents

Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects

on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention

extended data:

related extension: blockchain financial application:

since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency

standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency

in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016

the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology

on June 1, 2020, Xinhua news agency was authorized to broadcast the "overall plan for the construction of Hainan free trade port" issued by the CPC Central Committee and the State Council, which will "actively participate in the formulation of international rules for cross-border data flow, and establish standards and rules for data rights confirmation, data trading, data security and blockchain finance" as one of the key tasks of Hainan free trade port before 2035

3. Now it has entered the era of digital currency. In recent years, digital currency is very popular. For example, blockchain is the focus of people's attention. Now more and more people begin to pay attention to blockchain. Many people are concerned about blockchain's entry into China's market. Domestic policies have not explained blockchain in detail. Many people are worried about whether blockchain is legal? Is blockchain legal in China? Xiaobian, let's explain the blockchain in detail

on April 9, 2017, Hangzhou municipal government and a company jointly set up a $10 billion xiongan global blockchain innovation fund, which can promote the development of blockchain projects. This initiative has also attracted the attention of many relevant financial people. At present, Hangzhou blockchain Instrial Park is one of the important initiatives funded and developed by the municipal government, I believe this case has also become one of the representative cases in China. Since then, more and more blockchains have developed all over the country<

at present, China has a new understanding of digital currency, analyzing the value of digital currency in essence, and relevant departments are also actively participating in the corresponding research. The central bank has set up a special research group and digital currency Research Institute, hoping to further explore the digitalization of sovereign currency. From the side, it can be seen that China has a positive attitude towards blockchain technology, and the Chinese government has repeatedly stressed the important role of blockchain technology in reshaping the global financial pattern

with the development of global economy, the Chinese government has realized the commercial development of domestic blockchain projects. From the blockchain projects invested by Hangzhou municipal government, it can be seen that more and more provinces will start to carry out blockchain projects in the future, which can promote the development of local economy

is blockchain legal in China? At present, the Chinese government is actively studying blockchain, and has carried out blockchain related projects in some provinces. Through the above introction, I believe that people should have a certain understanding of the blockchain. I believe that in the near future, there will be more and more blockchain projects, which can promote the development of domestic economy and enable more and more people to get more wealth from blockchain projects.

4. Yes, since the central government emphasized that the blockchain should be regarded as an important breakthrough for independent innovation of core technology and accelerated the development of blockchain technology and instry innovation, many places have issued relevant policies to seize the air of blockchain instry. If you want to know more about blockchain, you can pay attention to huocoin University, which also has online live classes.

Behind any investment with extremely high yield, there may be a deception of "you want his interest, but he wants your principal"

on July 4, 2018, a recording of Li Xiaolai, known as "China's richest man in bitcoin", was exposed, causing an earthquake in the currency circle. In nearly an hour's recording, Li Xiaolai made sharp comments on many coin circle tycoons and taught them how to cut leeks from retail investors

Although China has rectified and banned ICO in accordance with the law in September last year, it is not uncommon for project parties to avoid legal supervision through the mode of foreign registration and underground ICO. This requires the regulatory authorities to strengthen governance, establish perfect instry standards, and promote the good development of the blockchain instry

for investors, on the one hand, they should polish their eyes and not blindly follow the temptation of the so-called "Internet red". If you really believe Li Xiaolai's words of negating value investment and advocating speculation, it will be the right choice for him and eventually become the leek to be picked by others. On the other hand, we should invest rationally. Behind any investment with extremely high yield, there may be a deception like "you want his interest, but he wants your principal"

6. Blockchain is at the end of 2008. In the paper bitcoin: a peer-to-peer e-cash system

7. According to statistics, if the central learning area of the Political Bureau of the 18th CPC Central Committee is happy, he will quarrel, and it is impossible for him to publicize it. This is a new situation, and it is impossible for senior students to exist in a process and the number of times at home.
