[Summary] Some basic knowledge and technical points of Golang Ethereum development

With the continuous development of blockchain technology, Ethereum, as one of its representatives, has become one of the preferred platforms for building decentralized applications (DApps). In Ethereum development, Golang has become an increasingly popular development language. This article will introduce some basic knowledge and technical points of Golang Ethereum development.

1. Introduction to Golang

Golang (also known as Go) is a relatively new programming language developed by Google. The main difference between Golang and other languages is its efficiency and simplicity. Golang is designed to solve the problem of writing maintainable, high-performance concurrent programs, which makes it ideal for Ethereum development.

Golang has the following features:

1. Efficient built-in user-mode concurrent processing (such as goroutines, channels)
2. Automatic garbage collection (GC) mechanism
3. Fast compilation time
4. Static type (type-safe) and supports abstract types and interfaces
5. Supports cross-compilation for multiple platforms
6. Open source

2. Introduction to Ethereum

Ethereum is a decentralized blockchain platform that not only supports currency transactions (ETH), but also supports the construction of DApps. Ethereum provides a smart contract platform based on the Solidity programming language. Smart contracts can be deployed and executed automatically through the Ethereum network.

3. Advantages of using Golang for Ethereum development

Using Golang for Ethereum development has the following advantages:

1. Compared with other programming languages, Golang is The code is more concise and easier to maintain.
2. Golang is inherently capable of concurrent processing, which is exactly what Ethereum needs.
3. Because Golang has a fast compiler, development is far more efficient than other traditional languages (such as Java, C#).
4. Golang can be used to write many different types of applications and has first-class network programming, data storage and data analysis tools.

4. Golang Ethereum development tools and frameworks

There are many very useful tools and frameworks when developing Golang Ethereum.

1. Web3.go

Web3.go is a Golang library that provides access to Ethereum smart contracts. It allows developers to use the Golang language to interact with Ethereum smart contracts.

2. Ethereum.go

Ethereum.go is a Golang library for the Ethereum network. It provides an API for Ethereum nodes, which allows developers to write various Ethereum applications, such as ERC20 token contracts, etc.

3. Geth

Geth is an Ethereum node client that provides a command line interface and RPC interface. It can be used to access the Ethereum network, mine, and execute smart contracts, among other functions.

4. Ethereum Swarm

Ethereum Swarm is a decentralized storage solution provided by Ethereum. It allows developers to store data on the Ethereum network and access it using BZZ tokens. Swarm provides many Golang tools, which allow developers to use Golang to build DApps.

5. How to use Golang for Ethereum development

Golang Ethereum development needs to follow the following steps:

1. Install Golang

Installing Golang requires at least Go 1.8 or above. Download the stable version suitable for your operating system from the official website https://golang.org/dl/.

2. Install the Solidity compiler

The Solidity compiler can compile Solidity code into Ethereum smart contracts. Visit http://solidity.readthedocs.io/en/develop/installing-solidity.html to download the version appropriate for your operating system.

3. Write Golang package

Use Golang development tools (such as Goland or VS Code, etc.) to write Golang packages based on Web3.go or Ethereum.go to facilitate integration with Smart contracts interact.

4. Write Solidity smart contract code

Write Solidity smart contract code and compile it on the Solidity compiler.

5. Deploy contract

Deploy the compiled smart contract on the Ethereum network and obtain the corresponding contract address.

6. Using the contract address in the Golang program

Insert the contract address into the Golang program to interact with the smart contract.

6. Conclusion

Golang Ethereum development is growing and receiving more and more attention, especially when it comes to decentralized application development that requires efficiency and simplicity. In writing this article, we explored the basic knowledge and technical points of Ethereum development in Golang, provided some useful tools and frameworks, and also told how to use Golang for Ethereum development. I believe that after reading this article, you have a deeper understanding of Golang Ethereum development.
