In this book, we take you on a fun, hands-on and pragmatic journey to learning decentralized application (DApp) development on the Ethereum blockchain using the Solidity programming language. You'll start building your first Ethereum smart contract within minutes. Every section is written in a bite-sized manner and straight to the point as I don't want to waste your time (and most certainly mine) on the content you don't need. In the end, you will have what it takes to develop a real-life decentralized eBay Clone app. In the first chapter, we see how Ethereum works and why do we care about it. In the second chapter, we will create our first working smart contract with Ethereum where we learn how to interact with Ethereum as developers. We will then move on to chapters three and four where we will learn about compiling, deployment and testing of Ethereum apps. All these will prepare us for development of our decentralized eBay clone smart contract and the React user front end in chapter five and six. The goal of this book is to teach you how to build decentralized apps with Ethereum. We won't be talking a lot about trading cryptocurrencies, how to invest in Ethereum or how to trade Ethereum (ether) coins. We will have a good overview of Ethereum and cryptocurrencies but we will not be going into super in-depth academic discussion of them as our focus in this book is to have the practical knowledge of how to work with and build products with Ethereum. Table of Contents: CHAPTER 1: INTRODUCTION TO ETHEREUM CHAPTER 2: INTRODUCTION TO SMART CONTRACTS CHAPTER 3: COMPILING WITH SOLC, UNIT TESTING WITH MOCHA & GANACHE CHAPTER 4: DEPLOYING SMART CONTRACTS TO TEST/MAIN NETWORKS CHAPTER 5: EBAY SMART CONTRACT CHAPTER 6: REACT FRONTEND FOR EBAY SMART CONTRACT

Building on Ethereum

Building on Ethereum

This book covers most of them, as well as many of the the eventual problems you'll face once you're project is growing. For instance, what happens when your contract reaches the maximum size and can no longer be deployed?

In-App purchases represent an undeniably huge potential revenue stream for any game or application. Consider that Fortnite sold over 1 billion dollars worth of in-game purchases in less than a year from its inception. Most traditional game platforms are "walled gardens" where all the assets that gamers purchase come straight from the company who wrote the game. That's good for the company; they're the only source of magic swords. But for the players, frankly, it stinks.With Ethereum, those assets could live on the public blockchain and actually be owned by the users, who could sell or trade them like CryptoKitties or any other ERC-721 Non-fungible Token (NFT). When a player tires of a game after a year or two, she could sell all her assets to other players to recoup her investment.This is the vision behind the In-App Pro Shop, an application the author built and describes in detail in the book. The source code is available on GitHub, so you can download it and follow along, learning the Ethereum development ecosystem as you go. Any developer seeking to learn Ethereum smart contract development will have many of the same questions: What language(s) should I use? What blockchain tech stack do I need to get started? What framework(s) will I use to build the UI? What should the project structure look like?The answers to these questions lead to even more, and the options can seem overwhelming. This book covers most of them, as well as many of the the eventual problems you'll face once you're project is growing. For instance, what happens when your contract reaches the maximum size and can no longer be deployed? How can your contract get information from off the blockchain, like current Ethereum exchange rates?The author doesn't attempt to define every term or make this book a canonical reference to Ethereum development. The field is moving far too swiftly for that. Rather, he leads you through the decision points you'll encounter when you try to set up a project and grow it beyond trivial scope.

Technology is constantly evolving, and blockchain is taking development to new places, as mobile did a decade ago – and Ethereum is the leading platform for creating this new wave of applications. This book reveals everything you need to create a robust decentralized application (more commonly known as DApp). Unlike other books on the topic, this one focuses on the web application layer, and guides you in creating great experiences on top of the Ethereum blockchain. You’ll review the challenges and differences involved in developing DApps as opposed to traditional web applications. After a brief introduction to blockchain history and Ethereum in particular, you’ll jump directly into building a sample decentralized application, to familiarize yourself with all the moving pieces. This book offers specific chapters on querying and rendering data from the blockchain, reacting to events, interacting with user accounts, sending transactions, managing gas, handling confirmations and reorganizations, and more. You will also find a chapter dedicated to Solidity that will give you the necessary means to understand and even build your own smart contracts. Other important topics covered include building backend servers that act as indexing layers, and managing storage efficiently with solutions like the interplanetary file system, or IPFS. Last but not least, you will find chapters that examine the biggest problems on Ethereum today: onboarding and scalability. These include the state of the art of the available strategies to tackle them, such as meta-transactions, smart accounts, ENS, state channels, sidechains, and more. What You'll Learn Connect to the blockchain from the browser and send transactions from client-side Build a web app that provides a read-only interface to a blockchain contract Create a wallet interface for arbitrary fungible tokens, displaying the user’s balance and allowing for simple transfers to other addresses Develop a web app that stores large blobs of data off-chain, and keeps a reference to it on-chain (e.g. avatars, long text descriptions) Produce a web app that relies on a centralized server for indexing on-chain information to be presented to the user Who This Book Is For Web developers focused on client-side applications, with knowledge of JavaScript and HTML/CSS. You do not need any prior knowledge of Blockchain, Ethereum, or cryptocurrency.
