Blockchain JavaScript
Blockchain is a decentralized ledger that maintains a continuously growing list of data records secured from tampering and revision. Every user is allowed to connect to the network, send new transactions to it, verify transactions, and create new blocks. This book will teach you what Blockchain is, how it maintains data integrity, and how to create real- world Blockchain projects using Ethereum. With interesting real-world projects, you will know learn how to write smart contracts which run exactly as programmed without any chance of fraud, censorship or third-party interference, and build end-to-end applications for Blockchain. You will learn concepts such as cryptography in cryptocurrencies, ether security, mining, smart contracts, and solidity. The blockchain is the main technical innovation of bitcoin, where it serves as the public ledger for bitcoin transactions. Chapter 1, Understanding Decentralized Applications, will explain what DApps are and provide an an overview of how they work. Chapter 2, Understanding How Ethereum Works, explains how Ethereum works. Chapter 3, Writing Smart Contracts, shows how to write smart contracts and use geth's interactive console to deploy and broadcast transactions using web3.js. Chapter 4, Getting Started with web3.js, introduces web3js and how to import, connect to geth, and explains use it in Node.js or client-side JavaScript. Chapter 5, Building a Wallet Service, explains how to build a wallet service that users can create and manage Ethereum Wallets easily, even offline. We will specifically use the LightWallet library to achieve this. Chapter 6, Building a Smart Contract Deployment Platform, shows how to compile smart contracts using web3.js and deploy it using web3.js and EthereumJS. Chapter 7, Building a Betting App, explains how to use Oraclize to make HTTP requests from Ethereum smart contracts to access data from World Wide Web. We will also learn how to access files stored in IPFS, use the strings library to work with strings, and more. Chapter 8, Building Enterprise Level Smart Contracts, explains how to use Truffle, which makes it easy to build enterprise-level DApps. We will learn about Truffle by building an alt-coin. Chapter 9, Building a Consortium Blockchain, we will discuss consortium blockchain.
