A Brief Introduction to Web3: Decentralized Web Fundamentals for App Development

Journey into the world of Web3-based application development, its related protocols, and its usage in developing decentralized applications. This book will explain how programmable blockchains are revolutionizing the world of web applications, which can be run on decentralized platforms or peer-to-peer networks like IPFS.
You'll start with an introduction to decentralization with a focus on blockchain implementations like Ethereum and Bitcoin. You'll then learn to develop simple decentralized applications (dApps) using Solidity, the language used for developing apps with Ethereum as well as smart contracts, wallets, gateways and NFTs. This book also covers how security and scale are addressed by L2 networks for scaling Bitcoin and Ethereum blockchains.

A Brief Introduction to Web3 is your go-to guide for setting up simple Web3 applications using the Ethereum blockchain programming model.
What You Will Learn

• Build NFT tokens
  
• Examine Web3 differs from Web2-based applications
• Understand the fundamentals of blockchain and the corresponding data structures around it
• See how consensus and trustless computing can be performed using blockchain
• Use Solidity and Truffle to build Web3 applications

Who This Book Is For

Software developers and architects who are looking to hone their skills in dApps and web3 applications developed on sound principles of decentralized computing.

深入探索基於Web3的應用程式開發世界，了解相關協議以及在開發去中心化應用程式中的應用。本書將解釋可程式化區塊鏈如何革新網頁應用程式的世界，這些應用程式可以在去中心化平台或點對點網絡（如IPFS）上運行。
您將從去中心化的介紹開始，重點介紹像以太坊和比特幣這樣的區塊鏈實現。然後，您將學習使用Solidity開發簡單的去中心化應用程式（dApps），Solidity是用於開發以太坊應用程式和智能合約、錢包、閘道和NFT的語言。本書還介紹了如何通過L2網絡解決比特幣和以太坊區塊鏈的安全性和擴展性問題。

Web3簡介是您建立使用以太坊區塊鏈編程模型的簡單Web3應用程式的指南。
您將學到什麼

• 建立NFT代幣


• 研究Web3與基於Web2的應用程式的不同之處


• 了解區塊鏈的基礎知識以及相應的數據結構


• 了解如何使用區塊鏈實現共識和無信任計算


• 使用Solidity和Truffle建立Web3應用程式

本書適合對去中心化計算原則下的dApps和Web3應用程式開發技能有興趣的軟體開發人員和架構師。
