책소개

▶Book Description
Blockchain is a decentralized ledger that maintains a continuously growing list of data records that are 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, making it permission-less.
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 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 about concepts such as cryptography in cryptocurrencies, ether security, mining , smart contracts, solidity, and more. You will also learn about web sockets, various API services for Ethereum, and much more.
The blockchain is the main technical innovation of bitcoin, where it serves as the public ledger for bitcoin transactions.

▶What You Will Learn
？ Walk through the basics of the Blockchain technology
？ Implement Blockchain's technology and its features, and see what can be achieved using them
？ Build DApps using Solidity and Web3.js
？ Understand the geth command and cryptography
？ Create Ethereum wallets
？ Explore consortium blockchain

▶Key Features
？ Create powerful, end-to-end applications for Blockchain using Ethereum
？ Write your first program using the Solidity programming language
？ Change the way you think and design your applications by using the all new database-Blockchain

▶Who This Book Is For
This book is for JavaScript developers who now want to create tamper-proof data (and transaction) applications using Blockchain and Ethereum. Those who are interested in cryptocurrencies and the logic and database empowering it will find this book extremely useful.

▶What this book covers
？ 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.

？ Narayan PrustyNarayan Prusty is a full-stack developer, with five years of experience in the field. He specializes in Blockchain and JavaScript. His commitment has led him to build scalable products for startups, the government, and enterprises across India, Singapore, USA, and UAE.At present, Ethereum, Bitcoin, Hyperledger, IPFS, Ripple, and so on are some of the things he uses on a regular basis to build decentralized applications. Currently, he is a full-time Blockchain SME (Subject-Matter Expert) at Emirates National Bank of Dubai.He has already written two books on JavaScript titled Learning ECMAScript 6 and Modern JavaScript Applications. Both these books were reviewed and published by Packt.He starts working on something immediately if he feels it's exciting and solves real work problems. He built an MP3 search engine at the age of 18, and since then, he has built various other applications, which are used by people around the globe. His ability to to build scalable applications from top to bottom is what makes him special.Currently, he is on a mission to make things easier, faster, and cheaper using the blockchain technology. Also, he is looking at possibilities to prevent corruptions, fraud, and to bring transparency to the world using blockchain technology.
