Building Blockchain Projects

By: Narayan Prusty

Overview of this book

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.

Preface

Summary


In this chapter, you learned about three important Ethereum libraries: Hooked-Web3-Provider, ethereumjs-tx, and LightWallet. These libraries can be used to manage accounts and sign transactions outside of the Ethereum node. While developing clients for most kinds of DApps, you will find these libraries useful.

And finally, we created a wallet service that lets users manage their accounts that share private keys or any other information related to their wallet with the backend of the service.

In the next chapter, we will build a platform to build and deploy smart contracts.
