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

History of Hyperledger

The Hyperledger project was founded in 2015, when the Linux Foundation announced the creation of the Hyperledger project. It was founded in conjunction with a number of enterprise players, including IBM, Intel, Fujitsu, and JP Morgan. The goal was to improve and create industry collaboration around blockchain technology so that it would be usable for complex enterprise use cases in the key industries most suitable to blockchain disruption: technology, finance, and supply chain.

The project gained substance in 2016, when the first technology donations were made. IBM donated what was to become known as Hyperledger Fabric, and Intel donated the code base that became Hyperledger Sawtooth.

Unlike most projects in the blockchain space, Hyperledger has never issued its own cryptocurrency. In fact, the executive director of Hyperledger has publicly stated that there never will be one.
