This is the code repository for Mastering Blockchain, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.
Blockchain is a distributed database that enables permanent, transparent, and secure storage of data. The blockchain technology is the backbone of cryptocurrency – in fact, it’s the shared public ledger upon which the entire Bitcoin network relies – and it’s gaining popularity with people who work in finance, government, and the arts.

Blockhchain technology uses cryptography to keep data secure. This book gives a detailed description of this leading technology and its implementation in the real world.
This book begins with the technical foundations of blockchain, teaching you the fundamentals of cryptography and how it keeps data secure. You will learn about the mechanisms behind cryptocurrencies and how to develop applications using Ethereum, a decentralized virtual machine. You will explore different blockchain solutions and get an exclusive preview into Hyperledger, an upcoming blockchain solution from IBM and the Linux Foundation. You will also be shown how to implement blockchain beyond currencies, scability with blockchain, and the future scope of this fascinating and powerful technology.
All of the code is organized into folders. Each folder starts with a number followed by the application name. For example, Chapter03.
The code will look like the following:
sudo apt-get install \
build-essential pkg-config libc6-dev m4 g++-multilib \
autoconf libtool ncurses-dev unzip git python \
zlib1g-dev wget bsdmainutils automake
All examples in this book have been developed on Ubuntu 16.04.1 LTS (Xenial). As such, it is recommended to use Ubuntu. However, any appropriate operating system, either Windows or Linux, can be used, but examples, especially those related to installation, may need to be changed accordingly. Examples related to cryptography have been developed using the OpenSSL 1.0.2g 1 Mar 2016 command-line tool. Ethereum solidity examples have been developed using Browser Solidity, available online at https://ethereum.github.io/browser-solidity/. Ethereum's homestead release is used to develop Ethereum-related examples. At the time of writing, this is the latest version available and can be downloaded from https://www.ethereum.org/. Examples related to IoT have been developed using a Raspberry Pi kit by Vilros, but any latest model or kit can be used. Specifically, Raspberry Pi 3 Model B V 1.2 has been used to build a hardware example of IoT. Node.js V7.2.1 and npm V3.10.10 have been used to download related packages and run Node.js server for IoT examples. The Truffle framework has been used in some examples of smart contract deployment, and is available at http://truffleframework.com/. Any latest version available via npm should be appropriate.
