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.

Using MetaMask and Remix IDE to deploy a smart contract

MetaMask was introduced in Chapter 12, Further Ethereum. It is an interface between the Ethereum blockchain and the web browser. It enables easy access to the blockchain and is quite useful for development activities.

As MetaMask injects a web3 object into the browser, we can use it with Remix IDE to deploy contracts to the blockchain.

It is very easy to deploy new contracts using MetaMask and Remix. Remix IDE provides an interface where contracts can be written in solidity and then deployed on to the blockchain.

We will use Remix IDE and MetaMask to deploy a sample smart contract to the local running private blockchain that we just created in the last section.

In the exercise, a simple contract that can perform various simple arithmetic calculations on the input parameter will be used. As we have not yet introduced Solidity, the aim here is to demonstrate the contract deployment and interaction process only...
