Overview of this book

Hyperledger is an open-source project and creates private blockchain applications for a range of domains. This book will be your desk reference as you explore common and not-so-common challenges faced while building blockchain networks using Hyperledger services. We'll work through all Hyperledger platform modules to understand their services and features and build end-to-end blockchain applications using various frameworks and tools supported by Hyperledger. This book's independent, recipe-based approach (packed with real-world examples) will familiarize you with the blockchain development cycle. From modeling a business network to integrating with various tools, you will cover it all. We'll cover common and not-so-common challenges faced in the blockchain life cycle. Later, we'll delve into how we can interact with the Hyperledger Fabric blockchain, covering all the principles you need to master, such as chaincode, smart contracts, and much more. We'll also address the scalability and security issues currently faced in blockchain development. By the end of this book, you will be able to implement each recipe to plan, design, and create a full-fledged, private, decentralized application to meet organizational needs.

Deploying, testing, and exporting business network archives using the Composer command-line interface

We implemented all the models, transactions, and query functions in the previous recipe. It is now time for us to deploy the application to the Fabric network.

Getting ready

There are multiple ways to do this. In the Playground, there is an option to export a file as a .bna file. We can then upload the .bna file to Ubuntu server to begin deployment. We can also update all related files in the Ubuntu server's farmatrace-network folder, including logic.js, permissions.acl, org.packt.farmatrace.cto, and queries.qry, and then manually generate a .bna file.
