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.

Building an ERC-20 token

In this section, we will build an ERC-20 token. In previous chapters, we saw several ways of developing smart contracts, including writing smart contracts in Visual Studio Code and compiling them and then deploying them on a blockchain network. We also used the Remix IDE, Truffle, and MetaMask to experiment with various way of developing and deploying smart contracts. In this section, we will use a quick method to develop, test, and deploy our smart contract on a Goerli test network. We will not use Truffle or Visual Studio Code in this example as we have seen this method before; we are going to explore a quicker method to build and deploy our contract.

In this example, we will see how quickly and easily we can build and deploy our own token on the Ethereum blockchain network.

Pre requisites

We will use the following components in our example:
