• Create powerful, end-to-end applications for Blockchain using Ethereum
• Write your first program using the Solidity programming language
• Change the way you think and design your applications by using the all new database-Blockchain

Book Description

Blockchain is a decentralized ledger that maintains a continuously growing list of data records that are secured from tampering and revision. Every user is allowed to connect to the network, send new transactions to it, verify transactions, and create new blocks, making it permission-less.

This book will teach you what blockchain is, how it maintains data integrity, and how to create real-world blockchain projects using Ethereum. With interesting real-world projects, you will learn how to write smart contracts which run exactly as programmed without any chance of fraud, censorship, or third-party interference, and build end-to-e applications for blockchain.

You will learn about concepts such as cryptography in cryptocurrencies, ether security, mining, smart contracts, solidity, and more. You will also learn about web sockets, various API services for Ethereum, and much more.

The blockchain is the main technical innovation of bitcoin, where it serves as the public ledger for bitcoin transactions.

What you will learn

• Walk through the basics of the blockchain technology
• Implement blockchain's technology and its features, and see what can be achieved using them
• Build DApps using Solidity and Web3.js
• Understand the geth command and cryptography
• Create Ethereum wallets
• Explore consortium blockchain

Who this book is for

This book is for JavaScript developers who now want to create tamper-proof data (and transaction) applications using Blockchain and Ethereum. Those who are interested in cryptocurrencies and the logic and database empowering it will find this book extremely usefu

Architecting Enterprise Blockchain Solutions helps engineers and IT administrators understand how to architect complex blockchain applications in enterprise environments. The book takes a deep dive into the intricacies of supporting and securing blockchain technology, creating and implementing decentralized applications, and incorporating blockchain into an existing enterprise IT infrastructure.

Blockchain is a technology that is experiencing massive growth in many facets of business and the enterprise. Most books around blockchain primarily deal with how blockchains are related to cryptocurrency or focus on pure blockchain development. This book teaches what blockchain technology is and offers insights into its current and future uses in high performance networks and complex ecosystems.

- Provides a practical, hands-on approach

- Demonstrates the power and flexibility of enterprise blockchains such as Hyperledger and R3 Corda

- Explores how blockchain can be used to solve complex IT support and infrastructure problems

- Offers numerous hands-on examples and diagrams

Get ready to learn how to harness the power and flexibility of enterprise blockchains

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.

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

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.
