Mastering Blockchain - Third Edition

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.

Compilers are used to convert high-level contract source code into the format that the Ethereum execution environment understands. The Solidity compiler, solc, is the most common one in use, which is discussed next.

The Solidity compiler

solc converts from a high-level Solidity language into Ethereum Virtual Machine (EVM) bytecode so that it can be executed on the blockchain by the EVM.


solc can be installed on a Linux Ubuntu operating system using the following commands:

$ sudo apt-get install solc

If Personal Package Archives (PPAs) are not already installed, those can be installed by running the following commands:

$ sudo add-apt-repository ppa:ethereum/ethereum
$ sudo apt-get update

To install solc on macOS, execute the following commands:

$ brew tap ethereum/ethereum

This command will add the Ethereum repository to the list of brew formulas:

$ brew install solidity

This command will produce a long output...
