GitHub blockchain programming
you should be talking about the technology of virtual currency. This source code is usually developed by C + +.
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 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.
blockchain is an important concept of bitcoin, which is essentially a decentralized database and serves as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access A new distributed infrastructure and computing method for programming and operating data by using intelligent contract composed of automated script code
go language + blockchain training course:
1 What are the advantages of go
advantages of go
1: performance
2: language performance is very important
3: developer efficiency & don't be too innovative
4: concurrency & Channel
5: fast compile time
6: team building ability
7: powerful ecosystem
8: gofmt, Mandatory code format
9: grpc and protocol buffers
can be directly compiled into machine code, independent of other libraries. Glibc version has certain requirements, and deployment is completed by throwing a file
static type language has the feeling of dynamic language. Static type language can check out most hidden problems when compiling, while dynamic language has the feeling that there are many packages that can be used and the efficiency of writing is very high.
why should we learn go language and what are the advantages of go
1. What are the advantages of go
1: performance
2: language performance is very important
3: developer efficiency & don't be too innovative
4: concurrency & Channel
5: fast compile time
6: team building ability
7: powerful ecosystem
8: gofmt, Mandatory code format
9: grpc and protocol buffers
can be directly compiled into machine code, independent of other libraries. Glibc version has certain requirements, and deployment is completed by throwing a file
static type language has the feeling of dynamic language. Static type language can check out most hidden problems when compiling, while dynamic language has the feeling that there are many packages that can be used and the efficiency of writing is very high.
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.
however, as Ethereum and hyperledger fabric have the best support for go language, go language must be learned
next, I'll give you the answer to another question, hoping to help you
Background: I started to study blockchain technology in 2015, so I have a certain understanding of blockchain
statement: it is estimated that everyone who sees this question wants to get started with blockchain, so this answer is mainly an introction at the entry level. It's just an introction at the entry level, which is not suitable for blockchain practitioners to improve their learning.
of course, GitHub is not omnipotent, and it can cope with most personal software development without it.
First of all, it is clear that GitHub is not very suitable for beginners. That is to say, if you are a programming beginner and want to learn some programming knowledge through the Internet, then GitHub is not suitable, because GitHub is the world's largest version control and open source project management software, but if you are a developer with practical development experience, So it's very good to learn some new programming knowledge and improve yourself through GitHub
1. First of all, why is GitHub only suitable for beginners and not for beginners? GitHub is the world's largest version control system and open source project management website. There are a large number of open source projects in which programming language and private projects of some enterprises. In short, the company uses GitHub for team cooperation and management, while some developers use it as a hosting platform for open source projects to share communication technology with developers around the world. Now it's clear that GitHub is mostly a relatively complete project without basic knowledge of programming, so it's not suitable for beginners to learn. For those who want to improve themselves after they get started, they can improve themselves by focusing on some open source projects, learning and analyzing or communicating with some developers
How to use GitHub to learnfirst of all, if you want to learn through GitHub, you must learn how to use GitHub, which is also a very important skill. First of all, we need to learn how to publish projects through GitHub, view other people's open source projects, and use GitHub for team cooperation. This is only part of it. We also need to learn how to contribute our own code to an open source project on GitHub, and how to communicate with some developers through GitHub. Because these things are more complex, I won't explain them in detail, In a word, only when you learn how to use GitHub can you learn from GitHub
finally, it is very important to pay attention to some technology communities and open source projects to improve our programming ability, especially some open source communities. Many excellent new technologies are proced in these communities, so as a computer learner and a software developer, updating learning knowledge through the network is one of our basic skills
