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.

Smart contracts

We discussed smart contracts at length in the previous Chapter 10, Smart Contracts. It is sufficient to say here that Ethereum supports the development of smart contracts that run on the EVM. Different languages can be used to build smart contracts, and we will discuss this in the programming section and at a deeper level in Chapter 14, Development Tools and Frameworks and Chapter 15, Introducing Web3.

There are also various contracts that are available in precompiled format in the Ethereum blockchain to support different functions. These contracts, known as precompiled contracts or native contracts, are described in the following subsection.

These are not strictly smart contracts in the sense of user-programmed Solidity smart contracts, but are in fact functions that are available natively to support various computationally intensive tasks. They run on the local node and are coded within the Ethereum client; for example, parity or geth.
