Central government talks about 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

2. It is reported that the Central Bank of China is testing the digital currency based on blockchain
according to media reports, the people's Bank of China has completed a test on December 15, which shows how to conct transactions and clearing in the distributed ledger system
it is reported that this test was concted jointly with China's mainstream commercial banks, including ICBC, Bank of China and Weizhong bank< The report reads: "the people's Bank of China believes that digital currency can not only rece circulation costs, but also increase transparency, inhibit money laundering and tax evasion."
the report even suggests that Shanghai bill exchange pilot digital currency and set up a national bank bill transaction. At the same time, the people's Bank of China will also establish a digital currency Research Center, and is recruiting experts in big data, cryptography and blockchain technology< The report comes after Zhou Xiaochuan, the governor of the people's Bank of China, issued a statement in February in which he hinted that the people's Bank of China was considering using blockchain to issue digital currency
moreover, this test was concted at the time when the people's Bank of China launched an investigation into China's bitcoin exchange, which started early this month and has led to many changes in trading policies
as the world's first standard digital currency, Puyin takes 1 billion Tibetan tea as the primary standard asset, writes 1 billion Tibetan tea assets into the blockchain through digital encryption technology, and records the identification, evaluation and right confirmation of Tibetan tea.

Some time ago, a picture of Chinese aunts appearing on the scene of the blockchain conference became popular on the Internet. For a while, it caused a heated discussion. Netizens said one after another: "aunts have been targeted by the blockchain." In fact, since a few years ago, when the concept of blockchain came out, there have been some illegal elements carrying out pyramid selling activities in the name of blockchain, which has become one of the latest varieties of pyramid selling. In fact, with the development of blockchain, all kinds of virtual currencies emerge as the times require. Most of them are scams. In the name of "virtual currency" and "blockchain", swindlers carry out scams. This is mainly to make use of the psychology that investors do not understand virtual currency and blockchain, but want to catch up with the upsurge of virtual currency investment. This kind of scam seems complicated, but it is also very simple. However, once it is cheated, it is difficult to recover the investment

in a word, blockchain technology is not a fraud, but is used by swindlers to cheat investors by using information asymmetry

4. 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 a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block.

5. 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"

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

8. 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.
