课程名称：从零开始学习Ethereum web3js 课程概述： Ethereum是基于区块链技术的开放软件平台，允许开发者构建和部署去中心化应用程序。与比特币类似，Ethereum也是一种分布式公共区块链网络。然而，两者在目的和能力上存在显著差异。比特币主要用作点对点电子现金系统，用于进行在线支付，而Ethereum的区块链则侧重于运行任何去中心化应用程序的编程代码。 课程还将介绍web3.js——一个以太坊JavaScript API，它是一系列库，允许您通过HTTP或IPC连接与本地或远程以太坊节点进行交互。此外，智能合约的概念也将被探讨。智能合约是用于描述可以促进金钱、内容、财产、股份或任何有价值的东西交换的计算机代码。当运行在区块链上时，智能合约像自运行的计算机程序，当特定条件满足时会自动执行。由于智能合约在区块链上运行，其执行过程严格按照编程要求进行，不受审查、停机、欺诈或第三方干预的影响。 本课程将引导学员从基础知识开始，逐步掌握Ethereum和web3.js的核心概念与应用。
What is Ethereum? Ethereum is an open software platform based on blockchain technology that enables developers to build and deploy decentralized applications.Like Bitcoin, Ethereum is a distributed public blockchain network. Although there are some significant technical differences between the two, the most important distinction to note is that Bitcoin and Ethereum differ substantially in purpose and capability. Bitcoin offers one particular application of blockchain technology, a peer to peer electronic cash system that enables online Bitcoin payments. While the Bitcoin blockchain is used to track ownership of digital currency (bitcoins), the Ethereum blockchain focuses on running the programming code of any decentralized application.web3.js - Ethereum JavaScript APIweb3.js is a collection of libraries which allow you to interact with a local or remote ethereum node, using a HTTP or IPC connection.What is a smart contract?Smart contract is just a phrase used to describe a computer code that can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Because smart contracts run on the blockchain, they run exactly as programmed without any possibility of censorship, downtime, fraud or third-party interference.
