Blockchain Developer's Guide

By: Brenn Hill, Samanyu Chopra, Paul Valencourt, Narayan Prusty

Overview of this book

Blockchain applications provide a single-shared ledger to eliminate trust issues involving multiple stakeholders. It is the main technical innovation of Bitcoin, where it serves as the public ledger for Bitcoin transactions. Blockchain Developer's Guide takes you through the electrifying world of blockchain technology. It begins with the basic design of a blockchain and elaborates concepts, such as Initial Coin Offerings (ICOs), tokens, smart contracts, and other related terminologies. You will then explore the components of Ethereum, such as Ether tokens, transactions, and smart contracts that you need to build simple DApps. Blockchain Developer's Guide also explains why you must specifically use Solidity for Ethereum-based projects and lets you explore different blockchains with easy-to-follow examples. You will learn a wide range of concepts - beginning with cryptography in cryptocurrencies and including ether security, mining, and smart contracts. You will learn how to use web sockets and various API services for Ethereum. By the end of this Learning Path, you will be able to build efficient decentralized applications. This Learning Path includes content from the following Packt products: • Blockchain Quick Reference by Brenn Hill, Samanyu Chopra, Paul Valencourt • Building Blockchain Projects by Narayan Prusty

About Packt


Now you have a good idea of the different subprojects that make up Hyperledger and an awareness of the tooling you can use to build Hyperledger-based projects. Hyperledger is a set of technologies for building private blockchain networks for enterprises, versus the public and tradeable networks, such as Ethereum and Bitcoin. The Hyperledger family is made of six projects and a set of support tools, all with subtly different focuses and advantages to suit different projects.

Over time, the different projects are expected to become more consistent and interoperable. For instance, Hyperledger Burrow and Hyperledger Sawtooth have already cross-pollinated with the Seth transaction family, which allows Sawtooth to run Ethereum smart contracts. It is expected that tools such as Cello and Composer will be extended to support additional Hyperledger projects in time, leading to an increasingly robust ecosystem.

Next, we will discuss Ethereum in depth. Ethereum is a public blockchain network...
