Blockchain Development (0) How to start learning ethereum and Blockchain

Lihe August 28, 2016 Many people are puzzled by the blockchain and Ethereum, do not know how to learn, this article briefly discussed some of the learning methods and resources.
I. The relationship between Ethereum and blockchain

From the blockchain history, Bitcoin was first born, there was no blockchain technology and terminology, and the industry extracted the technology architecture and system from Bitcoin, called Blockchain technology. Blockchain technology from Bitcoin is called the Blockchain 1.0 era, when the application is mainly electronic money and to focus on transactions, such as a variety of counterfeit coins. And Ethereum to the blockchain into the 2.0 era, Blockchain 2.0 is not overturned 1.0, but on the basis of 1.0 to realize the block awareness, value awareness, Turing complete, and the details of the optimization, thus forming a smart contract with the characteristics of the Blockchain 2.0. Bitcoin is positioned in one application, and Ethereum is positioned on the platform where you can use smart contracts for a variety of applications.

So, learn the blockchain, just learn the ether. second, the way to get started in Ethereum

For those who have not contacted the blockchain, it is recommended to attend the daily use of Ethereum.

1. Using the client

Here's a lot of tutorials, recommended an ethereum wallet tutorial

2. Mining

Mining a lot of tutorials, generally distributed in the various mineral pools, here recommended a domestic mine pool tutorial, and can join the pools of the group to exchange. The domestic mine pond has www.f2pool.com,www.bw.com and so on several big ore pond.

3, browse the public chain block information

After experiencing these things, you can view your account and transactions through the blockchain browser, and feel more intuitively.

Through the above operation, the basic can be counted on the blockchain has a preliminary understanding and perception. three, the ether square each item description

After the Ethereum release, there are a number of clients, but also support multiple platforms, beginners are often confused by a variety of clients, this article is a detailed summary.

The Ethereum client is categorized by language and is divided into different projects on GitHub, source code address: https://github.com/ethereum/, although the Ethereum client is numerous, but there are two common features:

1, the same language of the client on different platforms use is exactly the same

2, different languages of the client (mist, Geth, ETH, etc.) between the same platform (Linux, Windows or OSX) share the same application configuration, and its command line can use the same parameters.

The following is a breakdown of the purpose and characteristics of each client using the project on GitHub:

(i) Go-ethereum project

Development language: Go language

Client Files: Geth

Interface: Command line

Applicable platforms: Windows, Linux, and OSX

Features and features: The project is the most widely used Ethereum client, most of the nodes are running the client, tutorials and examples are also the most, recommended, can be used for mining, the formation of private chain, manage accounts, deployment of smart contracts and other common functions, can not compile smart contracts.

(ii) Webthree-umbrella project

This project consists of 3 clients

Development language: C + +

Client files: Alethzero, mix, and ETH

Using platforms: Windows, Linux, and OSX

Interface: Graphical interface

Features and features: The project is strictly a shell of the Cpp-ethereum project, written by the former Cto,gavin Wood of the Ethereum Foundation, so the popularity is high and the usability is good. Alethzero is a graphical wallet client, which corresponds to the function of Geth, but is completely graphical. But with the introduction of the Graphic wallet mist, which was pushed by the Ethereum Foundation, is fading. Mix is the development IDE for smart contracts (Ethereum called Dapp) that supports the authoring, commissioning, deployment, and full graphical interface of smart Contracts (DAPP), but has stopped developing and the development team has turned to remix. The ETH is a command-line client feature written in C + + and Geth.

(iii) Mist Project

Development language: JavaScript

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

Using platforms: Windows, Linux, and OSX

Interface: Graphical interface

Features and features: The project is the main project of the Ethereum Foundation, Mist is not just a wallet, but the future of Dapp (application app for smart contracts) market, similar to the Apple market, where you can have your account, you can browse, publish and sell Ethereum Dapp applications. At present, because the development is not comprehensive, the name temporarily displayed as Ethereum-wallet, the role is very simple, is a wallet function. Strongly recommended for future mainstream clients.

(iv) solidity project

Development language: C + +

Client Files: Solc

Using platforms: Windows, Linux, and OSX

Interface: Command line interface

Features and features: The project is the Ethereum Smart Contract (DAPP) programming language, using SOLC as a compiler, the project is mainly used for compiling, strictly speaking is a basic compiler platform, general development can be used to replace the mix.

(v) browser-solidity Project

Development language: C + +

Client files: Display in browser

Using platforms: Windows, Linux, and OSX

Interface: Browser interface

Features and features: The project is a smart contract browser version of the development environment, can support in the browser directly development, debugging and compilation, for beginners, can quickly get started, do not need to install, very convenient, direct access to address use: https://ethereum.github.io/ browser-solidity/

(vi) Pyethereum project and ETHEREUMJ project

The Pyethereum project is an Ethereum client written in the Python language, and the ETHEREUMJ project is an Ethereum client written in the Java language, except that the language is different and the functionality of the client Geth written in the previous go language is exactly the same.

(vii) Etheminer project

Development language: C + +

Client Files: Ethminer

Using platforms: Windows, Linux, and OSX

Interface: Command line

Features and Features: This project is part of the Cpp-ethereum project, used for GPU mining with geth, more than 100 times higher than the CPU mining efficiency, can also be used for mining pool mining Four, Ethereum common site (including smart contracts)
