As we all know, after the release of Ethereum, it has multiple clients, and it can also support multiple different platforms. However, many beginners in the blockchain field are often confused by the various clients. In fact, current Ethereum clients are classified by language, and they can be divided into different projects according to language. They basically all have two characteristics in common, that is, clients of the same language have the same usage on different platforms, and clients of different languages have the same application configuration on the same platform. So what exactly is this Ethereum client? Let the editor of the currency circle take you through an article to understand the Ethereum client.

## What is the Ethereum client?

Ethereum has multiple operational clients, developed and maintained by teams using different languages. This is a significant achievement, by limiting the impact of the vulnerability to that part of the network where clients are running or running independently, allowing for many different implementations of the network to be implemented simultaneously when the network is deployed equally to all users.

Ethereum will undergo the most significant upgrade to its architecture since its inception - moving from proof-of-work (PoW) to the merged proof-of-stake (PoW) network. The consensus achieved by changing the true state of PoW (PoW) on this blockchain maintains network security. But the security, scalability and appearance aspects that the new architecture will bring are also related to this risk in the way that individual clients are dominant.

## Introduction to Ethereum client

1. go-ethereum project

Development language: go language

Client files: Geth

Interface: command line

Applicable platforms: windows, linux and OSX

Functions and features: This project is the most widely used Ethereum client. Most nodes are running this client. It has the most tutorials and examples. It is recommended for use. It can be used for mining, setting up private chains, managing accounts, and deploying intelligence. Common functions such as contracts cannot be compiled into smart contracts.

2. webthree-umbrella project

This project contains 3 clients

Development language: c++

Client files: AlethZero, Mix and Eth

Platforms used: windows, linux and OSX

Interface: graphical interface

Functions and features: Strictly speaking, this project is a shell of the cpp-ethereum project. It is the former CTO of the Ethereum Foundation, Gavin
It was written under the leadership of Wood, so it is very popular and easy to use. AlethZero is a graphical wallet client, which corresponds to the functions of Geth, but is fully graphical. However, with the subsequent launch of Mist, the graphical wallet promoted by the Ethereum Foundation, it gradually declined. Mix is a development IDE for smart contracts (called DAPP in Ethereum). It can support the writing, debugging, and deployment of smart contracts (DAPP) with a full graphical interface. It is currently the most mainstream Ethereum smart contract development platform. It is very convenient and highly recommended. . Eth is a command line client written in C++ that has the same functions as Geth.

3. Mist project

Development language: Java

Client files: Mist (currently using the name Ethereum-Wallet)

Platforms used: windows, linux and OSX

Interface: graphical interface

Functions and features: This project is the main project of the Ethereum Foundation. Mist is not just a wallet, but a future DAPP (smart contract application APP) market, similar to the Apple market, where you can have your account and browse , publish and buy and sell DAPP applications of Ethereum. At present, because the development is not comprehensive enough, the name is temporarily displayed as Ethereum-
Wallet, its function is also very simple, it is the function of a wallet. Highly recommended, the future mainstream client.

4. Solidity project

Development language: C++

Client file: solc

Platforms used: windows, linux and OSX

Interface: command line interface

Functions and features: This project is a programming language for Ethereum smart contracts (DAPP). It uses solc as the compiler. This project is mainly used for compilation. Strictly speaking, it is a basic compilation platform. MIX can be used as an alternative for general development.

5. browser-solidity project

Development language: C++

Client file: displayed in browser

Platforms used: windows, linux and OSX

Interface: browser interface

Functions and features: This project is a development environment for the browser version of smart contracts, which can support direct development, debugging and compilation in the browser. For beginners, you can get started quickly without installation. It is very convenient and can be used directly by accessing the address. :

6. pyethereum project and ethereumj project

The pyethereum project is an Ethereum client written in python language, and the ethereumj project is an Ethereum client written in JAVA language. The only difference is that the languages have the same functions as the previous client Geth written in GO language.

7. ethaminer project

Development language: C++

Client files: ethminer

Platforms used: windows, linux and OSX

Interface: command line

The above is the detailed answer of the editor of the currency circle to the question of what is the Ethereum client. I hope everyone can understand the Ethereum client in one article. Because there are many Ethereum clients, there are many Ethereum clients for us to choose from, and we can use different clients during development and deployment. Generally speaking, when developing, we recommend Ganache, which is a private chain client running on a personal computer. It can centralize smart contracts and transactions, simplifying the development of dapps. And using this client, we can also quickly see how our applications affect the blockchain, which can help us further optimize our development.
