How to do fruit 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". <

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. 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. I saw an agricultural traceability project of dmtc rice before -

is to install an RFID chip on the proct, which records the whole life cycle of the proct, which is equivalent to that every commodity has an identity tag. These data will be linked in real time and form a tamperable information to ensure the safety and traceability of goods
my understanding is probably like this, so should other traceability procts
you can also ask me if you have any questions, I hope it will help you!

6. In essence, currency issuance and chain reform are different expressions, which means that enterprises or other organizational forms token their own value through blockchain technology, change the existing organizational structure, wealth distribution and value circulation mode, and rebuild a new economic rights and interests system. The incubation area of star exchange is looking for potential traditional enterprises free of charge, To provide them with technical support, the implementation of traditional enterprise chain reform program. Xingke issues digital currency through silubium public chain, which is a public chain that has cultivated different kinds of blockchain applications in many countries, and has strong practical application value.

7. You can take a look at Yu Lingxiong. He is a big IP in the coin circle, and the public recognition is very high. I recommend you to take a look at him.

8. It is suggested that we should find an organization to build a blockchain instead of doing it alone. For example, the coin win alliance can have better projects to do, and the God who works together can also make himself mature.
