Can go language develop blockchain?

can be developed. Blockchain is a programming idea, and in principle it can be implemented using any programming language. For example, go language, Solidity, C, C#, Java, and javascript can all implement blockchain development. Go language is designed to solve distributed computing, and blockchain is a typical distributed data storage system, so go language can develop blockchain. Moreover, Go is easy to learn and use, and can well meet the characteristics of blockchain development needs such as "high execution efficiency, high concurrency, cross-platform, and high network development requirements".

The operating environment of this tutorial: Windows 7 system, GO version 1.18, Dell G3 computer.

Blockchain is a programming idea that can, in principle, be implemented using any programming language. For example: C, Java, javascript, python, and Go can all be used to develop blockchain.

The programming language for developing blockchain---Golang

Go, also known as Golang, is an open source general programming language developed by Google. It was originally designed to Solving distributed computing is an emerging language in the field of cloud computing. The syntax of Go language is similar to that of C language. Its characteristics are: fast compilation speed, high execution efficiency, friendly network programming, high concurrency, and cross-platform. Go is easy to learn and use. It can well meet the needs of blockchain industry development such as "high execution efficiency, high concurrency, cross-platform, and high network development requirements" and other characteristics. It is a perfect match for blockchain development!

The underlying development of blockchain was mainly based on C in the early days. Now some projects are beginning to use Go language development. Projects written in Go include:

• HyperLedger Fabric: Most of the smart contracts built using HyperLedger Fabrics are written in Go.

#Why can Go language become the mainstream development language for blockchain?

Because the development of blockchain systems involves computing power and applications, these C languages ​​can naturally solve the problem, but the cumbersome development cost is too high. Use other upper-layer languages ​​​​such as Java, Python, etc. Although it can reduce development costs, the performance and blockchain computing power cannot keep up. Therefore, when developing blockchain technology, many companies will choose the Go language, which has low development costs and objective development performance, as the first choice language.

Go language is extremely efficient in developing blockchain and has obvious advantages, which are mainly reflected in the following aspects:

1) It can be directly compiled into machine code and does not rely on For other libraries, the version of glibc has certain requirements, and deployment is completed by just throwing a file in it.

2) A statically typed language, but with the feeling of a dynamic language. A statically typed language means that most hidden problems can be checked out during compilation. The feeling of a dynamic language is that there are many packages that can be used. Write It's very efficient.

3) The language level supports concurrency. This is the characteristic of Go, which inherently supports concurrency. Go supports concurrency in its genes. It can make full use of multiple cores and make it easy to use concurrency.

4) Built-in runtime supports garbage collection, which is one of the features of dynamic languages. Although GC is not perfect at present, it is enough to cope with most situations we can encounter, especially Go1. GC after 1.

5) Simple and easy to learn. The authors of Go language all have C genes, so Go naturally has C genes. Then Go keywords are 25, but the expression ability is very powerful and can support most of you. Features seen in other languages: inheritance, overloading, objects, etc.

6) Rich standard library, Go currently has a large number of built-in libraries, especially the network library is very powerful.

7) Built-in powerful tools. There are many tool chains built into the Go language. The gofmt tool automatically formats the code, which can make team review so simple. The code format is exactly the same, and it is difficult to think differently. .

8) Cross-platform compilation. If the Go code you write does not contain cgo, then you can compile Linux applications on the window system. How to do it? Go references the code of plan9, which is information that does not depend on the system.

9) Embedded C support, Go can also directly include C code, making use of the existing rich C library.
