Overview of this book

Ethereum is a blockchain-based, decentralized computing platform that allows running smart contracts. This book provides a basic overview of how Ethereum works, its ecosystem, mining process, and the consensus mechanism. It also demonstrates a step-by-step approach for building decentralized applications. This book begins with the very basics of Blockchain technology. Then it dives deep into the Ethereum architecture, framework and tools in its ecosystem. It also provides you an overview of ongoing research on Ethereum, for example, Layer 1 and 2 scaling solution, Stablecoin, ICO/STO/IEO, etc. Next, it explains Solidity language in detail, and provides step-by-step instructions for designing, developing, testing, deploying, and monitoring decentralized applications. In addition, you’ll learn how to use Truffle, Remix, Infura, Metamask, and many other Ethereum technologies. It’ll also help you develop your own cryptocurrency by creating ERC20, and ERC721 smart contracts from scratch. Finally, we explain private blockchains, and you learn how to interact with smart contracts through wallets.

Understanding Remix development fundamentals

In Chapter 5, Developing Your Own Cryptocurrency, we discussed the ERC-20 and ERC-721 smart contracts and wrote smart contract functions. Now, we can do a quick code verification using the Remix online IDE before we use Truffle to write a unit test. We learned about a basic Remix online IDE feature in Chapter 4, Solidity Fundamentals. In this section, we will explore more Remix features, namely the following:

  • Working with the Solidity compiler
  • Analysis
  • Testing
  • Deploying and running transactions
  • Debugging

Remix provides both online and local versions to work with. The online version is available at https://remix.ethereum.org. To install Remix on our local device, run the following npm command:

npm install -g remix-ide
remix-ide

Once it has been installed successfully, run the remix-ide command and open localhost:8080, as shown in the...
