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.

Chapter 3. Setting the Stage with a Business Scenario

The first two chapters were focused on setting the stage and defining the landscape of a blockchain project. We now understand how the technology works within a business framework and how the various Hyperledger projects aim to solve the problem of time and trust.

With an understanding of the components that make up Hyperledger Fabric, we will now delve into application design and implementation considerations. The next few chapters will take you through the steps of creating your very own smart contract and then integrating it to an application.

In order to make these exercises relevant, we will leverage a business use case with its roots in some older civilizations: trading and letters of credit.

The chapter's objective will be to introduce the business concept of letter of credit, walk you through the sample scenario we selected, and conclude by setting up our development environment.

In this chapter, we will:

  • Explore letters of credit
  • Review...
