Fengxiangrencom will launch blockchain channel

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". <

p>

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. At present, blockchain technology is mainly applied in smart contract, identity authentication and asset transaction

in addition to solving the security problem, blockchain technology can also change the following areas:

1. In the future, music right distribution is likely to enter the stage of blockchain, removing the intermediate link, so that musicians can get more direct income. In the past, record companies or the Internet were required to increase user stickiness. There were a lot of fees in the middle of promotion or song playing, but not many were really given to the authors, because the original right was still in the hands of several major record companies

2. Writing right is the same. For example, you may have to find a publisher before. This right can't be sold many times, and the money given to the author is also very small. With blockchain technology, all users need to pay the right fee to the author, not limited to a single publisher. Previously, Mr. Li Xiaolai did the press one project, which is mainly aimed at right distribution

3. The Internet of things and blockchain technology will combine to proce the blockchain Internet of things (Biot). Blockchain Internet of things can greatly rece the risk of hacker attacks. With the help of blockchain Internet of things, it may be as convenient as mobile phones to obtain warehouse sensor data

Kevin Kelly's book out of control has become the wind vane of the development of the Internet. In his later book necessity, he also mentioned that "technology has a preference in nature, which makes it move in a certain direction. On the premise that other conditions are the same, the physical and mathematical principles that determine the development of science and technology will favor certain specific behaviors

the development of blockchain technology is an "inevitable" trend, and bitcoin and some valuable digital currencies are only proced because of one of the needs. Today's blockchain is like the Internet in 1994. The development of the times will screen out the best technology and procts. It's just a matter of time

now there are too many "pseudo blockchain" projects focusing on blockchain, because too many people blindly invest in them without understanding. I want to make a fortune in this market. Those people are aiming at leeks that enter the coin circle without learning anything. They casually make small packages on the open public chain, issue a coin, hold a roadshow and want to circle a group of people to come in. They want to run after they circle money. In fact, they have no actual technical content and can't solve any practical problems.

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

4. What is digital currency? Is it the same thing as electronic money and virtual money
the difference between digital currency, electronic currency and virtual currency
in fact, digital currency is a kind of indexed RMB, a legal encrypted digital currency and an alternative currency in the form of electronic currency. Digital currency can be divided into two types: non cryptocurrency (e-gold, XRP) and cryptocurrency (bitcoin)
it can not be completely equivalent to the virtual currency in the virtual world, because it is often used for real goods and services transactions, not limited to online games and other virtual spaces. It is different from Alipay and WeChat, and Alipay, WeChat payment and mobile phone banks are all electronic money, not digital money. The popular digital currencies in 2016 include bitcoin, lightcoin, bitstock, etc. At present, there are thousands of digital currencies issued all over the world
virtual currency refers to the non real currency, especially the currency in the network virtual economy. The issuer is not the central bank, and it can only circulate in a specific virtual environment. In the case of the connection between virtual and reality, virtual currency has its real value. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point, roll counting of Shanda company, u-coin meter ticket launched by Sina (used for igome game), chivalrous Yuanbao (used for chivalrous road game), and grain silver (used for bixue Qingtian game). Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency. For example, bitcoin is illegal digital currency
since the beginning of the year, the relevant person in charge of the people's Bank of China has said that the future of mobile payment is bright, and the central bank is actively studying the relevant research results and practical experience at home and abroad to strive for the early issuance of digital currency. At the digital currency seminar of the people's Bank of China held on January 20, the relevant person in charge of the people's Bank of China disclosed that the central bank has set up a special research team since 2014 to conct in-depth research on the digital currency issuance and business operation framework, key technologies, circulation environment, etc., and strive to launch the digital currency issued by the central bank as soon as possible. At present, the research has achieved phased results
what benefits will digital currency bring to our lives
for this problem, the relevant person in charge of the central bank said that if the digital currency is successfully issued, it will bring many conveniences: it can effectively rece the high cost of the issuance and circulation of traditional paper money, and improve the convenience and transparency of economic transaction activities; It can rece money laundering, tax evasion and other illegal and criminal acts, enhance the central bank's control over money supply and money circulation, better support economic and social development, and help the comprehensive realization of Inclusive Finance; It helps to build a new financial infrastructure, further improve the payment system, improve the efficiency of payment and clearing, and promote the upgrading of economic quality and efficiency. More digital currencies can focus on bitMom

On January 14, 2020, Beijing time, Guangdong Zhongke intelligent blockchain Technology Co., Ltd. successfully held the global open source of the underlying technology of IOT blockchain and the launch conference of the ecosystem service system in Huangpu, Guangzhou. It released the underlying technology platform of IOT blockchain iovblockchain to the whole world, relying on mdpos algorithm and cross chain technology, It has officially become the representative platform of the fourth generation blockchain algorithm technology, and ranked among the top ten blockchain underlying technology platforms in the world. After China Science and Technology Corporation settled in Huangpu, in just two months, the number of patent applications for blockchain technology has reached 11.2% of the number applied by the people's Bank of China, and 1.3% of Alibaba, the world's largest patent application company for blockchain technology. It has become the backbone of Guangzhou Huangpu blockchain instry's successful incubation and participation in global blockchain technology competition. At the press conference, China Science and Technology Corporation, Guangzhou intelligent network automobile demonstration area operation center and Zhenbao Bus Group signed a tripartite agreement on blockchain technology application cooperation, which became another important scene of blockchain technology application in Huangpu District

the technological infrastructure route in the development of blockchain instry is particularly important, including the core content of underlying algorithm ability, open source service ability, ecosystem development ability, instry standardization process and digital chip instry application. After long-term scientific research incubation, China Science and Technology Corporation has completed the open source of the underlying blockchain algorithm and started the ecological service system, and will start the standardization construction of the blockchain of the Internet of vehicles and the design and development of digital chips in 2020. The launch of iovblockchain's open source and ecological services indicates that the underlying technology strength of China's blockchain is changing the global competition pattern of a new generation of information technology. In terms of underlying technology and business ecology, as one of the core technology representatives of blockchain, it leads China's blockchain instry and becomes a Chinese force participating in global competition

the press conference was guided by the instry and Information Bureau of Huangpu District of Guangzhou City and supported by the block chain instry association of Guangzhou City, the block chain alliance of Guangdong, Hong Kong and Macao Dawan District, blockchain 728, Guangdong automotive supplies chamber of Commerce and Internet of vehicles branch. More than 100 representatives from instry organizations and core blockchain enterprises attended the press conference and participated in the technology docking activities

According to experts, blockchain can be understood as a distributed public ledger, which is connected by various blocks into a chain. In the traditional bookkeeping system, the bookkeeping right is controlled by the central server

on the "account book" of blockchain, every point in the chain can record information on it, forming a point-to-point accounting system. Therefore, blockchain technology is considered as a decentralized technology

For example, in a village of 100 people, Zhang San bought a cow from Li Si and paid him 10000 yuan. In the past, he had to rely on Zhao Liu, a middleman, to transfer his 10000 yuan to Li Si

with the blockchain system, Zhang San can directly record his 10000 yuan to Li Si's account book, and the transaction information will be transmitted to the whole village, that is, the whole blockchain system, so that other 98 people can see the information. The whole transaction process is recorded by the system, which has the advantage of traceability to prevent the loss of Zhao Liu's account book or Li Si's denial of account

extended data

in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain became the core component of electronic currency bitcoin: as a public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently

the blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. The design of bitcoin has become a source of inspiration for other applications

blockchain is essentially a distributed ledger database, it is a series of data blocks generated by cryptography Association, and each data block contains effective confirmation information of multiple bitcoin network transactions

Statistics show that in 2017, China's e-invoice circulation reached 1.31 billion, and it is expected to reach 54.55 billion by 2022, maintaining an average annual growth rate of more than 100%. Recently, when talking about blockchain invoice, people's daily stressed that electronic invoice should be added with "lock", and blockchain's open consensus, decentralization, non tampering, distributed consistency and privacy protection are the "lock" of electronic invoice

finally, I repeat my idea: blockchain gives us freedom, and freedom will bring a lot of innovation. Innovation will eventually bring us wealth. I believe blockchain will have a similar development path. The core task of blockchain is to stabilize the value, establish a trust system with almost zero cost, and release the energy of indivials in pursuit of wealth preservation and appreciation
