Overview of this book

Blockchain and Hyperledger are open source technologies that power the development of decentralized applications. This Learning Path is your helpful reference for exploring and building blockchain networks using Ethereum, Hyperledger Fabric, and Hyperledger Composer. Blockchain Development with Hyperledger will start off by giving you an overview of blockchain and demonstrating how you can set up an Ethereum development environment for developing, packaging, building, and testing campaign-decentralized applications. You'll then explore the de facto language Solidity, which you can use to develop decentralized applications in Ethereum. Following this, you'll be able to configure Hyperledger Fabric and use it to build private blockchain networks and applications that connect to them. Toward the later chapters, you'll learn how to design and launch a network, and even implement smart contracts in chain code. By the end of this Learning Path, you'll be able to build and deploy your own decentralized applications by addressing the key pain points encountered in the blockchain life cycle. This Learning Path includes content from the following Packt products: • Blockchain Quick Start Guide by Xun (Brian) Wu and Weimin Sun • Hands-On Blockchain with Hyperledger by Nitin Gaur et al.

Defining business networks


We can summarize all these idea using the concept of a business network:

A business network is a collection of participants and assets than undergo a life cycle described by transactions. Events occur when transactions complete.

You may wonder what this means. After all that build-up, we're telling you that a couple of apparently simple sentences describe all this complexity?

The simple answer is yes—and we'll soon explain by describing in more detail what we mean by participants, assets, transactions, and events. Then, you'll see that all this rich behavior can be described by a relatively simple language vocabulary.

A deeper idea

In fact, there is a deeper idea behind business networks—that the language and vocabulary of technology should closely match that of the business domain, removing the need for significant translation between business concepts, and technology concepts. Business networks move away from the idea of disconnected technology by describing the underlying...
