By: Imran Bashir

Overview of this book

Blockchain is the backbone of cryptocurrencies, with applications in finance, government, media, and other industries. With a legacy of providing technologists with executable insights, this new edition of Mastering Blockchain is thoroughly revised and updated to the latest blockchain research with four new chapters on consensus algorithms, Serenity (the update that will introduce Ethereum 2.0), tokenization, and enterprise blockchains. This book covers the basics, including blockchain’s technical underpinnings, cryptography and consensus protocols. It also provides you with expert knowledge on decentralization, decentralized application development on Ethereum, Bitcoin, alternative coins, smart contracts, alternative blockchains, and Hyperledger. Further, you will explore blockchain solutions beyond cryptocurrencies such as the Internet of Things with blockchain, enterprise blockchains, tokenization using blockchain, and consider the future scope of this fascinating and disruptive technology. By the end of this book, you will have gained a thorough comprehension of the various facets of blockchain and understand their potential in diverse real-world scenarios.

Setting up a Sawtooth development environment

In this section, an introduction is given on how to set up a development environment for Sawtooth. There are a few prerequisites that are required in order to set up the development environment.

The easiest way to get Sawtooth up and running is by using Docker. In the following example, we will set up a 5-node network using Docker.


For this process, you'll need to first install Docker. In this example we are using:

$ docker -v
Docker version 19.03.8, build afacb8b

Sawtooth supports different consensus algorithms. In this example we will use PoET. However, other options are available too, such as PBFT. The YAML configuration files for both of these options are available at the links in the following sections.

Using PoET

The following link is available to download the YAML file for setting up Sawtooth with the PoET consensus algorithm:
