This article mainly explains "Why do you use go language to do blockchain". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "Why do you use go language to do blockchain"?

What can the Go language do?

Go language is mainly used for server-side development, and its positioning is to develop "large-scale software". It is suitable for many programmers to develop large-scale software together, and the development cycle is long and supports cloud computing network services. The Go language allows programmers to develop quickly, and as the software grows, it makes it easier for programmers to maintain and modify. It combines the efficiency of traditional compiled languages and the ease of use and expressiveness of scripting languages.

As a server programming language, Go is very suitable for dealing with logs, data packaging, virtual machine processing, file system, distributed system, database agent, etc.; in terms of network programming, Go language is widely used in Web applications, API applications, download applications, etc.; in addition, Go language can also be used in the field of in-memory database and cloud platforms. At present, many foreign cloud platforms are developed using Go.

Why do you use go language to make block chain?

1. Maintainable code in long-term projects.

The Go language is simple. And every time you come back to the code after a cessation, it doesn't have so many weird quirk to waste your time. In addition, it requires a small amount of learning, because its grammar is relatively popular, developers' learning curve is very smooth, this feature itself is very attractive to developers. This also leads to a low probability of Bug in (facilitate). So the whole development process seems so simple and fast. In general, the greater the amount of code, the harder the project is to maintain. A blockchain system requires thousands of lines of code, so we need a language to make maintenance easy.

2. Easily become a master of Go language.

Generally speaking, engineers who have some programming knowledge can quickly become Go language engineers in a month. When everyone needs the same language to work together, the Go language is the best choice because it is quick and easy to get started.

3. Speed and efficiency.

Unlike Python, Go is not an interpretive language-it is compiled. This drastically greatly reduces the number of Bug that pops up during the run. This is a bit like C, where the code is compiled and errors appear and processed at compile time before running; however, it is more advanced than C and more productive than JavaScript and Python.

A blockchain is in great need of efficiency, given that it uses an encryption (cryptographic) algorithm, and that it transfers a large amount of data (propagate) to the network and stores it on the network.

4. Born for distributed system.

This is evident in tools and software built with Golang. Docker, as a micro-service container, is also built with Golang. We have seen that we can easily handle millions of requests with microservices built by Golang.

5 、 Goroutines

Concurrency is to make several programs or parts of a program run at the same time, or in parallel, in order to improve computer throughput (throughput). Typically, concurrency is achieved through threads in Java or some other language. Go uses the "Goroutines" method. Goroutines means functions that can be executed at the same time as other functions. A Goroutine takes up about 4kb in memory, while a thread needs about 1024kb memory. As a result, Goroutines is 250 times smaller than the threads used in other languages, which allows it to execute a growing number of other Goroutines at the same time.

The Go language follows its guidelines-"Don't communicate through memory sharing, you should share memory through communication" (not to communicate by sharing memory, instead share memory by communicating). Parallel operations are of special significance to block chains. The ingenious and natural feature of running a large number of functions at the same time allows Go programs to run flexibly on distributed systems, which is the main requirement of blockchain. However, this feature has long been discovered, such as Docker,MongoDB,Netflix,Uber and so on, and their product features mainly rely on high concurrency.

6. Everyone in the blockchain field uses it.

Many DApps and tools based on stable blockchain use the Go language. You need a certain function, it is easy to find a corresponding library. Go is compiled, so it is executed directly by the operating system. This allows us to implement technologies like sandboxie (EVM (Ethereum Virtual Machine)) in Etay Fong more freely. And if it is Java, because its own running carrier JVM is a virtual machine, to do a sandboxie on it is essentially a higher level of abstraction, which is totally unnecessary and will waste computer resources. Of course, the experience of using Go is like a scripting language, and the cost of learning is very low, so it is very suitable for small projects. On QPS (The Queries per second), it is much better than Java, so it is suitable for building services with high request volume.

At this point, I believe you have a deeper understanding of "Why to use go language to do blockchain". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
