Introduction:

Developer. This book covers all aspects of front-end and back-end. Both front-end developers and back-end developers can learn and refer to it.

Architect. Blockchain itself is a model of distributed and cloud computing. This book describes the architectural design of a blockchain product in detail. Through this book, they can learn and master how blockchain builds complex adaptive systems based on P2P networks. .

College students, teachers, scientific researchers, etc. In the process of sharing the content of this book on the Internet, university teachers have already used it as teaching reference in actual teaching. From concept to code implementation, this book closely integrates theory and practice, explains the profound things in simple terms, and is suitable for systematic research and learning of blockchain technology.

Readers who learn Node.js. This book introduces the introductory knowledge of Node.js, including the technical principles and usage skills of Node.js. It is a complete Node.js use case. Junior and intermediate readers with a certain JavaScript foundation can learn and improve more deeply through this book. Use Node.js coding skills.

E. Introduction to blockchain technology, what programming languages ​​are involved

Go language is the mainstream language of blockchain
According to BOSS research According to the institute’s data survey, the blockchain positions currently being recruited
The mainstream languages ​​​​are Go and C++. Early blockchain systems and applications
The programs are mainly implemented in C++, and most companies now use it. Go language is used to
build a public chain system.
C++ is suitable for the development of local programs.
Go language is suitable for the development of network programs and local programs.
Advantages over C++Go:
/>Garbage collection
Clear semantics
Uniform format

Disadvantages:
The efficiency is currently not as high as C++, but for desktop programs, the efficiency problem is not big, because the hardware It's already very fast.

C++ is currently the mainstream language and I believe it will become a classic like C.
The meaning of becoming a classic is that people who learn it can get a good salary, but it is only a good salary.
In the future network world, Go has a great chance of becoming popular, and I think its future is promising.

The developers of Go include the founder of Unix and the founder of C language. They are the first generation of hackers and I believe they will do a good job.

Now the go full-stack + blockchain market is experiencing an unprecedented boom, and the situation is gratifying.

F. Introduction to blockchain technology, which programming languages ​​are involved

Go language

Go language (Golang) is a brand-new programming language launched by Google in 2009 A programming language that reduces code complexity without sacrificing application performance. Rob Pike, chief software engineer at Google, said: "We developed Go because the difficulty of software development over the past 10 years or so has been frustrating."

In addition to Bitcoin being developed in C++, At present, the clients of most mainstream workshops are developed with Go language, which is enough to show the status of Go language in the entire blockchain industry.

C++

C++ further expands and improves the C language and is an object-oriented programming language. C++ runs on a variety of platforms, such as Windows, MAC operating systems, and various versions of UNIX. C++ is a very widely used computer programming language. It is a general programming language that supports multiple programming patterns, such as procedural programming, data abstraction, object-oriented programming, generic programming, and design patterns.

Most blockchain companies choose to use C++ to write the bottom layer of the blockchain. The most famous ones are Bitcoin, Ripple, etc., which mainly reflect strong computation.

Java

Java is different from general compiled languages ​​or interpreted languages. It first compiles the source code into bytecode, and then relies on virtual machines on various platforms to interpret and execute the bytecode, thereby achieving the cross-platform feature of "write once, run anywhere". The development of blockchain projects has obvious dependence on Java.

Others include Python, system architecture, Ethereum, Linux, hyperledger, JavaScript, etc. will be covered.

G. How to develop blockchain How to do blockchain development

p>

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. If you want to learn this programming language, you must first find a good tutorial. Brothers in Arms Go Language + Blockchain Training has recently released a new set of Go language tutorials, and the teacher’s lectures are very good!

As the concept of "blockchain" is being discussed globally, related blockchain technology applications have quietly been added to daily life scenarios such as finance, logistics, credit reporting, manufacturing, and retail. Some experts said that in the future, blockchain will be closely related to people's lives, and the integration of blockchain technology into people's daily lives is the general trend.

The popularity of the blockchain market has triggered a large demand for talents based on blockchain technical personnel, and the popularity of blockchain talents is rising at light speed. According to the "2018 Blockchain High Salary List" released by Lagou.com, domestic corporate giants such as Tencent, Xiaomi, Suning, and JD.com have released numerous high-paying blockchain job requirements in an effort to explore blockchain-related technologies and applications. The list also points out that high-paying positions are mainly in demand for blockchain-related technical positions, among which Suning and Keda have given the highest monthly salary of 100k.

The huge market demand for technical talents will inevitably drive the explosive emergence and growth of the entire blockchain training market. Most training models can be divided into online training, traditional IT institution training and high-end offline short-term training camps. However, the market is also full of various blockchain training chaos during the hot evolution: the instructor qualifications are watered down. , Even the most basic names are not disclosed, the course syllabus is opaque, the teaching quality has shrunk, the class schedule is unreasonable, and the training fee standards are uneven, etc.

With the large-scale development of the entire blockchain training market, Brothers Education has joined hands with senior blockchain expert Yin Cheng and his Tsinghua Shuimu Weiming team to establish the Blockchain Academy, leveraging its professional and powerful technology The team of lecturers, detailed and comprehensive curriculum system, and massive actual enterprise blockchain projects are designed to deepen the field of blockchain education and training and cultivate more professional technical talents for enterprises and society.

Yin Cheng, a senior blockchain technology expert and the dean of Brotherhood Blockchain Academy, graduated from Tsinghua University. He has served as a Google algorithm engineer, the world's most valuable expert in the Microsoft blockchain field, and a Microsoft Tech.Ed conference Gold medal lecturer. Proficient in C/C++, Python, Go language, Sicikit-Learn and TensorFlow. With 15 years of programming experience and 5 years of teaching experience, he is a senior software architect, Intel software technology expert, a famous technical expert, and has many years of working experience in the world's top IT companies, Microsoft and Google. He has many years of experience in software programming and teaching as a lecturer, and has developed many products in human-computer interaction, education, information security, advertising, and blockchain systems. With profound project management experience and R&D experience, he has two talentsArtificial intelligence invention patent, and practical experience in developing electronic currency and deploying it to Microsoft Windows Azure. The teaching explanations are simple and profound, so that students can apply what they have learned.
