Blockchain By Example

By: Bellaj Badr, Richard Horrocks, Xun (Brian) Wu

Overview of this book

The Blockchain is a revolution promising a new world without middlemen. Technically, it is an immutable and tamper-proof distributed ledger of all transactions across a peer-to-peer network. With this book, you will get to grips with the blockchain ecosystem to build real-world projects. This book will walk you through the process of building multiple blockchain projects with different complexity levels and hurdles. Each project will teach you just enough about the field's leading technologies, Bitcoin, Ethereum, Quorum, and Hyperledger in order to be productive from the outset. As you make your way through the chapters, you will cover the major challenges that are associated with blockchain ecosystems such as scalability, integration, and distributed file management. In the concluding chapters, you’ll learn to build blockchain projects for business, run your ICO, and even create your own cryptocurrency. Blockchain by Example also covers a range of projects such as Bitcoin payment systems, supply chains on Hyperledger, and developing a Tontine Bank Every is using Ethereum. By the end of this book, you will not only be able to tackle common issues in the blockchain ecosystem, but also design and build reliable and scalable distributed systems.

Blockchain-Based Futures System

Reaching this chapter is a notable accomplishment in your Ethereum learning trip, during which you've thoroughly learned how to write smart contracts with Solidity, and how to build a complete DApp using web3.js and Drizzle. We focused, in the last two chapters, on building a decentralized web application on Ethereum using a set of tools, such as Remix or Truffle. In this walkthrough, we will learn how to harness a powerful language, such as Java, to build an Ethereum desktop or mobile application. Along the way, we will discover new concepts in Solidity, such as calling third-party APIs in your smart contracts or libraries.

As we learn by example in this book, we will break into finance and build a financial project that manages a futures smart contract using Java (SE). Throughout this interesting use case, we will go over the following points...
