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.

Requirements

In addition to integrity and consistency, which are also provided by public blockchains, there are several other requirements specifically for enterprise blockchains that make them suitable for enterprise use cases. In some cases, some requirements become even stricter in enterprise blockchains compared to public blockchains. For example, in public blockchains, eventual consistency is acceptable. However, in enterprise blockchains, the moment a transaction is committed, it should immediately finalize and irrevocably become part of the global record (state). Thus, we'll begin by briefly defining integrity and consistency before introducing specific requirements for enterprise blockchains.

  • Integrity: This attribute of a blockchain is provided by the use of hash functions and digital signatures, and plays a vital role in the overall security of the blockchain. Hash functions allow us to check for any data modifications, whereas digital signatures...
