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.

We have defined and built a business network model and then packaged it as a .bna file and deployed it to a Fabric network. We also set up a Composer REST server to communicate with the business network over HTTP. At the end, we have introduced IBM BaaS by running a marble application example in the IBM blockchain.

From now on, you should be able to build more complex blockchain projects using Hyperledger Fabric and Composer. If you have read the previous chapters, you'll now have an idea about the difference between business-driven blockhains, such as Hyperledger, and cryptocurrency-driven blockchains, such as Bitcoin or Ethereum. Finally, if you are not happy with Hyperledger and you are searching for an alternative, you should explore the Corda project (https:...
