How to use Go language for public blockchain development?

With the continuous development and application of blockchain technology, more and more developers developing applications are beginning to consider using the Go language for blockchain public chain development. The Go language has good performance and concurrent processing capabilities, and can play a great advantage in blockchain development. This article will introduce how to use Go language for public blockchain development.

1. Understand the public blockchain chain

Before starting to develop the public blockchain chain, we need to first understand what a public blockchain chain is. The public blockchain is a decentralized, changeable and public blockchain network. All participants can conduct transactions on the public chain and add new blocks to the database. The biggest feature of the public chain is decentralization. There is no centralized control node, but a decentralized network composed of many nodes.

2. Advantages and Disadvantages

Before developing the public blockchain chain, we need to understand the advantages and disadvantages of using the Go language for development. The following are the advantages and disadvantages of using Go language for development:

Advantages:

1. Efficiency: Go language has high efficiency and high performance, especially in concurrent processing. Advantage.

2. High concurrency: Because Go uses goroutine instead of threads for concurrent processing, it can greatly improve concurrent processing capabilities.

3. Memory management: The Go language comes with an automatic memory recycling mechanism and can set memory limits.

4. Portability: Go language can be developed across platforms and can be developed on Linux, Windows, MacOS and other systems.

Disadvantages:

1. Language features: Since the Go language is a relatively new language, its programmer community is relatively small and there are relatively few related available libraries and tools.

2. Difficult to debug: Due to the characteristics of the Go language itself, its debugging method is relatively complicated.

The above are the advantages and disadvantages of using Go language for blockchain public chain development. Developers need to make a choice based on their actual situation.

3. Build the environment

Before starting the development of the public blockchain chain, you need to set up a development environment, including the Go language environment, Geth node environment, etc.

1. Download the Go language environment

Download the Go language environment from the Go official website and install it according to the official tutorial. After the installation is complete, you can view the Go version of the current environment by entering go version on the command line.

2. Install the Geth node environment

Using the Geth node environment can simulate the situation of the Ethereum node to facilitate development and testing. You can download the installation package from Geth's official website and follow the official tutorial to install it.

4. Development

After successfully setting up the environment, you can start developing the public blockchain chain. Here we use a simple public chain development project to introduce how to use Go language for development.

1. Determine the development data type

Before starting development, you need to determine the data types required for this public chain development, such as blocks, transactions, nodes, wallets, etc.

2. Determine the transaction rules

After completing the determination of the data type, it is necessary to determine the transaction rules. Transactions in the public chain are regarded as database operations, so the transaction rules corresponding to each operation need to be determined.

3. Implement distributed nodes

In public chain development, nodes are a very important part. It is necessary to realize functions such as communication and data exchange between nodes, and to ensure the consistency of each node.

4. Implement the mining function

The mining function is necessary in the public chain and needs to be completed through the PoW (Proof of Work) algorithm, and its workflow can be realized in node interaction.

5. Implement smart contracts

Smart contracts are an important application in the public chain and need to be developed using the Solidity language.

The above is a simple development process of a public blockchain development project, which requires developers to develop based on their own actual conditions.

5. Summary

In this article, we introduced how to use Go language for public blockchain development. Using Go language for public chain development has the advantages of efficiency, high concurrency, memory management and portability, but there are also some inconveniences. Before starting development, you need to confirm the data types and transaction rules required for development. When implementing distributed nodes, mining functions and smart contracts, you need to strictly follow the process. It is hoped that in future public chain development, using the Go language for development can help developers complete development tasks more efficiently.
