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.

Project setup

Before we start to look in detail at the ICO implementation, it's a good idea to set up our working environment so we can incrementally add to the code as we walk through the explanation. For this project, we'll be using the Truffle framework and the Solidity language, which were introduced in Chapter 4, Peer to Peer Auction in Ethereum, and Chapter 5, Tontine Game with Truffle and Drizzle. The tutorial assumes you are working from a Linux-style terminal.

If you haven't already installed Truffle, do so by running the following command on the command line:

npm install -g truffle
For complete details on dependencies, and to troubleshoot any Truffle-specific issues, please refer to the official documentation at https://truffleframework.com/docs/truffle/getting-started/installation.

Next, create a project directory:

mkdir PacktCoin
cd PacktCoin
