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.

Introducing Web3

Web3 is a JavaScript library that can be used to communicate with an Ethereum node via RPC communication. Web3 works by exposing methods that have been enabled over RPC. This allows the development of user interfaces (UIs) that make use of the Web3 library in order to interact with contracts deployed over the blockchain.

In this chapter, we'll explore the Web3 API, and introduce some detailed examples of how smart contracts are written, tested, and deployed to the Ethereum blockchain. We will use various tools such as the Remix IDE and Ganache to develop and test smart contracts, and look at the methods used to deploy smart contracts to Ethereum test networks and private networks. The chapter will explore how HTML and JavaScript frontends can be developed to interact with smart contracts deployed on the blockchain, and introduce advanced libraries such as Drizzle. The topics we will cover are as follows:

  • Exploring Web3 with Geth
