People's network blockchain
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 incentives5. 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 Xi Jinping, general secretary of p>
, 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
bitcoin is a fraud, so we must be cautious in investment and financial management
even if it is called "hard currency", the price of gold will not only rise but not fall. There is no bubble in gold, but the price is too high, there is a bubble, and the bubble will eventually burst, such as virtual currency such as bitcoin. The more general virtual currencies, the closer bitcoin's value is to zero
this kind of currency, which is a purely calculated digital symbol, has no asset support, no financial revenue and expenditure, no cash reserve and no use value. It is only a circulation symbol. Once it loses its credit guarantee, it is a pile of beautiful printed waste paper. Investors should be alert that there is no so-called safe investment in this world, and all investments are risky
the people's Bank of China and other departments issued a document to severely punish the above-mentioned behaviors, making it clear that token trading is not protected by law. With some virtual currency trading platforms turning to overseas, speculative money speculation has also turned to "underground". In the face of continuous renovation, on the basis of continuous strict supervision, government departments should constantly upgrade the means and ability of supervision, and continue to increase publicity and crackdown on popular science, so as to avoid the masses being deceived
extended information:
investing in virtual currency is more of a kind of speculation. Investors should strengthen their risk prevention awareness and identification ability. Without confirming the identity of the other party, they should not be involved in money transactions, trust low-risk and high return investment procts, especially not join the investment and financing group without verification, These are often well-designed traps by telecommunication network fraudsters
it's better to purchase the investment and financial management accompanied by the children, and learn from the official and authoritative channels, and report to the police in time when they are found to be cheated. Properly protect all kinds of account password, identity information, etc., don't tell others easily. Any reference to the need for transfer and remittance should arouse high vigilance and consult with trusted acquaintances

extended data:
blockchain is far more than a technology, which involves the spirit of "multi-party cooperation". In modern society, a lot of things must rely on everyone's cooperation to achieve 1 + 1 & gt; But we should try our best to avoid the problem of "information asymmetry" in cooperation
therefore, members of the alliance should keep accounts and share data together, and make everything public to eliminate "information asymmetry", so as to protect everyone's interests and make the business environment develop healthily. Honest work will get e benefits, if cheating will naturally be known to all. Technology is the foundation to help achieve this pattern. This is the more important "blockchain thinking"

Heavy weight! What kind of information is released behind the people's Daily's re evaluation of special currency
April 18, 2018
as the wind vane of policy, people's Daily has a self-evident influence on all walks of life. On April 16, people's Daily published a comment on bitcoin and other digital currencies, to the effect that it is difficult to ban digital currencies completely, and landing payment should be opened. For a time, it triggered a big discussion on policy risk in the currency circle. Why did people's daily comment on bitcoin again? Does this mean that China will lift the ban on bitcoin? Today, I'd like to analyze the information hidden behind the people's daily article
therefore, it is boldly predicted that there can only be one form of bitcoin and blockchain enterprises in the future, that is, the form of Instrial Park supported by the state. As the saying goes, bitcoin is not a good blockchain if it does not solve the employment rate. At present, the whole market is not mature, and the state will not prohibit OTC trading for the time being. However, with the increasing economic risks, the supervision of the currency people will be more and more strict
in the past two days, there have been some good news, such as the blockchain channel on people's online, and some domestic mainstream media have also made some relatively positive reports on digital currency. Driven by the favorable situation, the mainstream currencies began to recover first
digital currency is a kind of global circulation thing, which can not be prohibited by a certain country or region. It can only be supervised to severely crack down on some illegal and criminal acts. However, as a mainstream digital currency, BCH's value advantage is fully demonstrated in the rising market.
With the announcement of the state accelerating the development of blockchain technology, various digital wallets and digital currency fraudsters using blockchain technology in the market have changed, which is known as the direction of state support in fact, this is e to some wrong elements
this kind of wallet is called digital wallet in the market, which allows wallet operators to buy ICO coins from abroad, so that operators can guess coins and increase the value of money. In short, it's the same as "postcards.". The only difference is that the object name is replaced by "blockchain cryptocoin". As long as everyone puts money in my wallet, everything is normal. You can say that you can deposit 100 today and 1000 tomorrow
