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.

Deploying the LC

First off, we need to start Hyperledger Fabric. For that, change the directory to fabric-dev-servers/ and start the ./startFabric.sh script as follows:

cd ~/fabric-dev-servers
sudo ./startFabric.sh

Next, create a peer admin card by executing the script ./createPeerAdminCard.sh. As a result, you'll get an output similar to the following:

If everything goes as expected, we can move on to building the business network archive.

Deploying business network

The first step is to create a business network archive from a directory on disk, by using the Composer command Line interface (Composer CLI) as follows:

composer archive create -t dir -n .

As a result, a business network archive file called [email protected]...
