We started this chapter with an understanding of the Ethereum platform as a way to achieve a decentralized economy. We explored the meaning of decentralization over political, logical, and architectural axes. Ethereum was found to be centralized about the logical axis. We dived deep into the web 3.0 technological stack of Ethereum and saw how swarm stores data, how whisper communicates, and how EVM interacts with blockchain, using smart contracts and a stack-based machine code. We identified that loops are a good rule-of-thumb for a language being Turing complete. We saw how gas is the magic sauce to curb performance related problems on Ethereum and how we need ether to top up our gas limit to run smart contract codes on the blockchain. We introduced the notion of uncle hash in the Ethereum blockchain. Also, we distinguished between ETH and ETC as a community activated hard fork. Mining requires huge memory access and hence prevents ASIC miners but encourages GPU miners. Finally...

Overview of this book
Ethereum is a public, blockchain-based distributed computing platform featuring smart contract functionality. This book is your one-stop guide to blockchain and Ethereum smart contract development.
We start by introducing you to the basics of blockchain. You'll learn about hash functions, Merkle trees, forking, mining, and much more. Then you'll learn about Ethereum and smart contracts, and we'll cover Ethereum virtual machine (EVM) in detail. Next, you'll get acquainted with DApps and DAOs and see how they work. We'll also delve into the mechanisms of advanced smart contracts, taking a practical approach.
You'll also learn how to develop your own cryptocurrency from scratch in order to understand the business behind ICO. Further on, you'll get to know the key concepts of the Solidity programming language, enabling you to build decentralized blockchain-based applications. We'll also look at enterprise use cases, where you'll build a decentralized microblogging site.
At the end of this book, we discuss blockchain-as-a-service, the dark web marketplace, and various advanced topics so you can get well versed with the blockchain principles and ecosystem.
