Building With Ethereum

Build products on top of Ethereum's new and expansive technological stack. Writing any good web application requires planning, care, and deft technical skills, but Ethereum's execution model presents its own challenges for engineers wishing to build applications on top of its smart contract layer. Building performant and engaging product experiences is one of the most important – and often underappreciated – roles in any company. This book looks at the full product stack needed to build such experiences on top of Ethereum smart contracts, weaving tutorials and case studies through more conversational discussions of the various constraints, trade-offs, and complexities involved in doing so. You’ll learn about the fundamentals of Ethereum from a new perspective, developing a strong understanding of how the Ethereum Virtual Machine (EVM) works and how it affects product engineering, as well as all the pieces of technology that go into decentralized apps (dapps) behindthe front end: RPC nodes, wallets, indexers, application hosts, and more. You’ll be exposed to plenty of UI, JavaScript code, and idiomatic ways to bring on-chain data into your front ends. And you’ll be given up-to-date knowledge of the best practices and future possibilities that decentralized computation might offer the product engineer. What You Will Learn Understand the EVM and how it works Gain insight into smart contracts and how apps connect to them Understand the difference between live data and indexed data How decentralization affects the UI of applications Build engaging, tasteful product experiences on top of Ethereum Who This Book Is For A confident – mid-level or senior – software engineer or web developer who hasn’t properly branched out into Ethereum; someone who might have scratched the surface, but wants adeeper understanding of the principles behind dapps, and who wants a head start on the hurdles faced while building them.
