How to build blockchain from scratch

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. Go is an open source programming language, which makes it easy to construct simple, reliable and efficient software. If you want to learn this programming language, you should first find a good tutorial. Brother Lian's go language + blockchain training has recently published a new set of go language tutorial, and the teacher's speaking is very good

with the global hot discussion of the concept of "blockchain", the application of blockchain technology has been quietly added to the daily life scenes such as finance, logistics, credit reference, manufacturing and retail. Some experts have shown that the future blockchain will be closely related to people's lives, and the integration of blockchain technology and people's daily life is the general trend

the popularity of the blockchain market has triggered a large number of talents demand based on blockchain technical personnel, and the popularity of blockchain talents is rising at the speed of light. According to the "2018 blockchain high salary list" released by lagou.com, Tencent, Xiaomi, Suning, Jingdong and other domestic enterprise giants have released many high salary blockchain post demands, trying to explore blockchain related technologies and applications. It is also pointed out in the list that the demand for high salary jobs is mainly based on blockchain related technical jobs, among which Suning and Keda have been given the highest monthly salary of 100k

the huge market demand for technical talents will inevitably lead to the explosive emergence and growth of the whole blockchain training market. Most of the training modes can be divided into online training, traditional IT organization training, and offline short-term training camps, which mainly focus on high-end forms. However, in the process of the hot market evolution, there are also a variety of blockchain training chaos: lecturers' qualifications are watered down, and even the most basic names are not disclosed, the syllabus is opaque, and the teaching quality is shrinking, Unreasonable class arrangement and uneven training fees and so on

with the large-scale development of the whole blockchain training market, brother company ecation, together with Yin Cheng, a senior blockchain expert, and his Tsinghua Shuimu Weiming team, has set up a blockchain college. With its professional and powerful team of technical lecturers, detailed and comprehensive curriculum system, and a large number of authentic enterprise blockchain projects, it aims to deepen the blockchain teaching and training field, And train more professional technical talents for enterprises and society<

Yin Cheng, a senior blockchain technology expert, graated from Tsinghua University, is the dean of brother Lian blockchain college. He once served as Google Algorithm Engineer, the world's most valuable expert in the field of Microsoft blockchain, and the gold medal lecturer of Microsoft tech.ed conference. Proficient in C / C + +, python, go language, sicikit learn and tensorflow. With 15 years of programming experience and 5 years of teaching experience, senior software architect, Intel Software Technology expert, famous technology expert, with many years of working experience in the world's top it company Microsoft Google. He has many years of experience in software programming and lecturing, and has developed many procts in human-computer interaction, ecation, information security, advertising and blockchain system. He has deep experience in project management and R & D, has two AI invention patents, and has practical experience in developing e-money deployed to Microsoft Windows azure. Teaching explanation is in simple language, so that students can apply what they have learned
the first stage: blockchain instry and go programming for 5 weeks
the second stage: cryptography and consensus algorithm for 2 weeks
the third stage: Ethereum source code analysis and development for 3 weeks
the fourth stage: Super ledger and node.js for 2 weeks
the fifth stage: bitcoin & EOS for 4 weeks
the sixth stage: comprehensive actual combat of the project

3. At present, blockchain technology is in the stage of rapid development. In the past two years, China has invested a lot of funds and talents in this area
technical personnel can learn this technology, while non-technical personnel can start from the instry media and instry community
If an enterprise needs to develop blockchain applications, it can entrust a professional third-party company. In Guangzhou, today's technology is good.

4. Blockchain was born in bitcoin. It is a decentralized database. As the bottom layer of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction. Here you can recommend a better practical application scenario of combining physical jewelry and blockchain technology. Domenech's Maobei digital virtual currency, please adopt

5. Xiao, who don't have much spare money, want to be big again. They pay thousands of yuan for the community such as Huo chain blockchain academy, and they can earn ten times as much when the market comes; Only bitcoin and Ethereum will earn the least, with little risk.

6. Blockchain is a kind of chain data structure that combines data blocks in order according to the time sequence, and it can't be tampered and forged by cryptography
virtual currency is simply a kind of digital currency using cryptographic algorithm, and virtual currency is invisible
the media of the central bank also said that private digital currency transactions will not be opened after the situation is stable

7. It's very difficult for indivials to make money by using blockchain. Generally, they can only get some tokens from some project platforms, such as the coin doctor community, and occasionally some candy airdrops. As for what blockchain can do, that's too much, blockchain + finance, blockchain + medical, blockchain + pension, blockchain + Tourism... Countless.

8. The development cost is about 500000 yuan. It's very easy to find websites with blockchain information types. You can network "blockchain network" and "blockchain XX network" and other information stations. There are at least thousands of them in China. No, let's go online.

9. Take out some spare money, do a good job in asset analysis and allocation, and hold it for a long time after buying. With the rapid development of the blockchain instry, it is likely that people will enjoy instry dividends, which is also the easiest way for ordinary people to participate
however, the recent market is really frightening. We can only rely on the support of faith. We don't know what will happen to the new currency AET, so we can only silently expect it to double
