A. What can the go language do

1. Server programming: If you used C or C++ to do those things in the past, Go is very suitable to do them, such as processing logs , data packaging, virtual machine processing, file system, etc.

2. Distributed systems, database agents, middleware: such as Etcd.

3. Network programming: This area is currently the most widely used, including Web applications, API applications, download applications, and Go’s built-in net/http package basically implements all the network functions we usually use. .

4. Development of cloud platforms: Currently, many foreign cloud platforms are developed using Go. The well-known Qiniu Cloud, Huawei Cloud, etc. have products developed using Go and are open source.

5. Blockchain: There is currently a saying that technical practitioners call Go language the development language of the blockchain industry. If you study blockchain technology, you will find that many blockchain systems and applications are developed using Go. For example, ehtereum is currently the most well-known public chain, and fabric is currently the most well-known. Alliance chains, both have go language versions, and go-ehtereum is also the officially recommended version of Ethereum.

Many later projects were re-implemented natively using the Go language. This process was simpler than other languages, which also contributed to the emergence of a large number of native development projects using the Go language. .

B. How about Go language

Go language is a new programming language launched by Google that can reduce the code size without losing application performance. Complexity. Rob Pike, chief software engineer at Google, said: We developed Go because software development has been frustratingly difficult over the past decade or so.

Go is the second programming language released by Google in 2009. In July 2009, Google released the Simple language, which is a BASIC language used to develop Android applications.

On January 10, 2010, Beijing time, the Go language Won the 2009 annual award announced by TIOBE. This award is given to the programming language with the largest market share growth in 2009.

Rob Pike, a senior software engineer at Google, said, "Go allows me to experience development efficiency that I have never experienced before." Pike said that, like today's C++ or C, Go is a a system language. He explained, "It allows for rapid development, but it's also a true compiled language, and the reason why we're open sourcing it now is because we think it's already very useful and powerful."

In 2007, Google started developing Go as a 20% project, which allowed employees to spend 20% of their time outside of their own work to invest in the project. In addition to Parker, other Google engineers are also members of the project.

Pike said that the running speed of compiled Go code is very close to that of C language, and the compilation speed is very fast, just like using an interactive language. None of the existing programming languages ​​are specifically optimized for multi-core processors. Go is a language written by Google engineers for this type of program. It's not designed for beginners in programming, but learning to use it isn't very difficult either. Go supports object-oriented and has features such as true closures and reflection.

In terms of learning curve, Parker believes that Go is similar to Java, and Java developers should be able to learn Go easily. The reason why Go is released as an open source project is to give the open source community the opportunity to create better tools for working with the language, such as plug-ins in the Eclipse IDE.

Go is not used in any of Google's publicly released web applications, but Google has developed several internal projects using the language. Parker said it's too early to say whether Go will have an impact on Google's upcoming Chrome OS, but Go can indeed be used with Native Client. He said that "Go allows applications to run perfectly in the browser." For example, using Go can implement Wave more efficiently, both in the front end and the backend.

Go has two compilers at the same time, one is Gccgo based on GCC, and the other is a set of compilers for 64-bit x64 and 32-bit x86 computers (6g and 8g) ). Google is currently developing its support for ARM chips and Android devices. Parker said, "The problem with Android phones is that we have never had a math coprocessor."

C. Why do some people think that the GO language will become a trend in developing underlying blockchains

Why should we learn Go language due to the explosion of blockchain?

The demand for blockchain talents in 2018 was 9.7 times that of the same period in 2017. According to statistics from recruitment websites, most positions in the blockchain require mastering the Go language.

E. 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 can reduce the complexity of code 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.

F. Does go language have a future?

Go language is specially optimized for the programming of multi-processor system applications. Programs compiled using GO can be comparable to the speed of C or C++ code, and are more secure and supported. Parallel processes. Not only can you develop the Web, you can also develop the underlying layer. Zhihu is developed by golang. The preferred language for blockchain is Go. Ethereum and Hyperledger are all based on Go language.
The goal of Go is to improve the management of existing programming languages' dependencies on libraries and other software elements that will be called repeatedly by applications. This language is also designed to solve multi-processor tasks due to the existence of parallel programming models.
Google has high hopes for Go. Its design allows the software to take full advantage of the simultaneous multi-tasking of multi-core processors and solve the troubles of object-oriented programming. It has modern programming language features, such as garbage collection, and helps Programmers deal with trivial but important memory management problems. Go is very fast, almost as fast as C or C++ programs, and can quickly create programs.
Currently, Go language is mainly used for server-side development. It is positioned to develop large-scale software. It is suitable for many programmers to develop large-scale software together. It has a long development cycle and supports cloud computing network services. The Go language allows programmers to develop quickly, and as the software continues to grow, it makes it easier for programmers to maintain and modify it. It combines the efficiency of traditional compiled languages ​​with the ease of use and expressiveness of scripting languages.
As a server programming language, Go language is very suitable for processing logs, data packaging, virtual machine processing, file systems, distributed systems, database agents, etc.; in terms of network programming, Go language is widely used in Web applications, API applications, downloads Applications, etc. In addition, the Go language can also be used in the fields of memory databases and cloud platforms. Currently, many foreign cloud platforms are developed using Go, so the development prospects of the Go language are still very good!

G. What is the go language suitable for?

The go language can be used not only to develop the web, but also to develop the underlying layer. Not only that, Ethereum and Hyperledger are both based on the go language, as well as the go language. version of btcd, you still need to understand this.

And it should be noted that the Go language rock is also more suitable for server development, cloud platform development, microservice practice and reconstruction, blockchain development (mainly led by Ethereum), etc.

The go language has many advantages. For example, the performance of the Go language is very good. The most important thing is that it can develop as efficiently as the Python language while having strong performance. You must know that the Go language is Static language, while Python is a dynamic language.

Of course, the Go language is relatively simple in terms of compilation and deployment, and the Go languageThe language can be directly compiled into machine code, and the compilation generates a static knowable slave file, which is relatively convenient.

Data expansion: Go is a smart script developed based on the Inferno operating system. Go was officially announced in November 2009, becoming an open source project and implemented on Linux and MacOSX platforms. Later, the implementation under Windows system was added. In 2016, Go was selected as the "TIOBE Best Language of 2016" by the software evaluation company TIOBE.
