Building Ethereum DApps: Decentralized Applications on the Ethereum Blockchain

Summary

Building Ethereum Dapps introduces you to decentralized applications based on the Ethereum blockchain platform. In this book, you'll learn the principles of Dapps development by rolling up your sleeves and actually building a few!

Foreword by Thomas Bertani.

About the Technology

Imagine unbreakably secure applications that handle personal and business transactions without any central agency controlling the process. Decentralized applications, or Dapps, do just this, shifting power to users. The Ethereum blockchain platform provides the tools you need to build Dapps, including an innovative "smart contracts" model and Solidity, a Dapp-aware JavaScript-like programming language.

About the Book

Building Ethereum Dapps teaches Dapps development on the Ethereum blockchain platform. You'll begin with a mental model of how Dapps operate, and then dive into designing and implementing smart contracts in Ethereum's Solidity language. You'll explore Ethereum smart contract development tools, like Truffle and Web3, and pick up best practices for design and security. Practical exercises throughout give you valuable hands-on experience.

What's inside

• Ethereum's key components
• Implementing smart contracts in Solidity
• Communicating with a smart contract in Web3
• Developing Dapps with Truffle
• Best practices for design and security improvement

About the Reader

For developers with intermediate experience in JavaScript or an OO language. Familiarity with blockchain concepts is helpful.
