Blockchain Development Guide
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<

publication time: 2016
recommendation: this book is mainly for programmers. Combined with API programming, we can tell you the principle and usage of cryptocurrency, as well as how to develop related software. For non programmer readers, the first few chapters of this book are still applicable as in-depth introction of bitcoin Book pdf download: https://quant.la/Download
Dahua blockchain is a book published by Tsinghua University Press in September 2019, written by Zhang Yingping. This book is a blockchain book that comprehensively explains bitcoin, Ethereum, super ledger and EOS, a blockchain development guide from engineer basic skills, development language to smart contract development, and a blockchain engineer guide from technology, project to career development planning
"Dahua blockchain"
"Dahua blockchain" is a blockchain book that pays equal attention to theory and practice, easy to understand and professional. The blockchain technology guide (the first three chapters) mainly explains the concept of blockchain, blockchain applications, bitcoin, Ethereum, super ledger, EOS and other mainstream blockchain technologies. Through learning, each reader can fully understand the implementation principles of mainstream blockchain technologies and understand the future development trend of blockchain. The practical part of development (the last two chapters) starts from the basic skills of blockchain, simulates the development of real blockchain projects, and explains in detail the design, development and deployment of smart contract and DAPP. Through learning, every reader can master the development of blockchain
At the beginning of self-learning blockchain related knowledge, we can adopt the "bottom-up" method, that is, through reading books, reading white papers , we can check the information , and then summarize and connect these knowledge , and integrate them into a relatively complete knowledge system so I went to the bookstore and bought a of the Analects of Confucius. I read it from the beginning to the end and found that there were too many details and insights in it, which could not be transmitted through any interpretation. Actually, I spent a lot of time and read a lot of interpretation before. I really want to abandon the essence and pursue the end. I have to work hard it's the same in every field. When you don't understand it, you will have a kind of inexplicable fear of it, thinking that it is high and unattainable. In order to step into these fields quickly, you will look for a lot of so-called "interpretation" and "news" around it 2. technical perspective Basic Stage: 1. Blockchain Development Guide - author Shentu Qingchun: the author's research on the bottom layer of rendant bitcoin is very in-depth, and the explanation is very easy to understand 2. Blockchain technology guide - author Zou Jun: as the first domestic book to explain blockchain from a technical perspective, it is worth reading. Since its publication in 2016, it has been consistently evaluated well 3. Principles, design and application of blockchain by Yang Baohua and Chen Chang: as the CTO of Zhigui, Chen Chang remembers that the previous ink chain was based on hyperledger fabric, so this book has a thorough explanation of hyperledger related open source procts 3. Blockchain world is divided into two parts. The first part comprehensively reviews the birth, growth and graal development of blockchain in 2008 through full and accurate information, introces in detail the originality of blockchain technology, the scientific mechanism and the artistic logic, and introces the application characteristics of blockchain through more than ten instry scenarios such as finance, anti-counterfeiting and medical treatment. In the second part, combined with the spirit of G20 summit and the 13th five year plan, the author explores the combination of blockchain and digital economy, as well as the author's views and suggestions on the development trend of the instry
Sharing area network:
the application scope of blockchain technology is still very wide. Based on the characteristics of decentralization, distrust, collective maintenance and reliable database, its application in the financial instry is the first step
blockchain is the underlying technology of bitcoin, and the application and development of blockchain in digital currency is mature
like the block chain based trading system development scheme provided by Yingtang Zhongchuang, the developed software system has great safety factor and transparency
At present, there are not many videos on the market for systematic learning of blockchain, and self-learning of blockchain is still relatively rare. You can apply for classes. Black horse programmers will open a new blockchain discipline. Teachers will teach in an easy-to-understand way and explain in simple terms. You can certainly learn it.

from the characteristics of the language itself, go is a very efficient language, which highly supports concurrency. Go language itself pays more attention to distributed systems, and concurrency processing is relatively good, such as advertising and search, which are high concurrency servers
go language advantages:
excellent performance, can be directly compiled into machine code, does not rely on other libraries, go is extremely fast. Its performance is similar to Java or C + +
concurrency is supported at the language level, which is the biggest feature of go. It is born to support concurrency, and go is the concurrency supported in gene, which can make full use of multi-core and make it easy to use concurrency
the built-in runtime supports garbage collection, which is one of the features of dynamic language. Although GC is not perfect at present, it is enough to cope with most of the situations we can encounter, especially GC after go1.1
it's easy to learn. The authors of go language all have the gene of C, so go naturally has the gene of C. There are 25 go keywords, but the expressive ability is very strong. It almost supports most of the features you've seen in other languages: inheritance, overloading, object, etc
rich standard libraries, go has built a large number of libraries, especially the network library, which is also my favorite part< As like as two peas, br / > built-in powerful tools, Go language is built with many tools chain, the best should be gofmt tools, automatic formatting code, make team review become so simple, code format is exactly the same, it is very difficult to think differently.
cross platform compilation and fast compilation. Compared with the sluggish compilation speed of Java and C + +, the fast compilation time of go is a major efficiency advantage
disadvantages of go language:
package management: package management of go language is absolutely not perfect. By default, it has no way to make a specific version of the dependency library, nor can it create replicable builds. In contrast, python, node and Ruby all have better package management systems. However, with the right tools, the package management of go language can also perform well
lack of development framework: go language does not have a major framework, such as Ruby's rails framework, Python's Django framework or PHP's laravel. This is a heated discussion in the go language community, because many people think that we should not start with using frameworks. This is true in many cases, but if you just want to build a simple crud API, it's much easier to use Django / djrf, rails laravel, or Phoenix
exception handling: go language can help developers deal with compilation errors by simply returning errors (or call stack) through functions and expected calling codes. Although this method is effective, it is easy to lose the scope of the error, so it is difficult to provide meaningful error information to users. Error package can solve this problem by allowing us to add context and stack trace to return error
another problem is that we may forget to handle errors. Static analysis tools such as errcheck and megacheck can avoid these errors. Although these solutions are very effective, they may not be the right way.
