Hands-on blockchain with Hyperledger: Building decentralized applications with Hyperledger Fabric and Composer

Detailed Summary of the Book

The book begins with an overview of blockchain technology, outlining its core principles, such as distributed ledgers, consensus mechanisms, and cryptographic security. This foundational understanding sets the stage for exploring Hyperledger, an enterprise-grade blockchain framework that has gained traction for its flexibility, scalability, and permissioned network capabilities.

Moving forward, the book introduces readers to Hyperledger Fabric, a framework for developing enterprise blockchain solutions. Key concepts such as chaincode (smart contracts), channels, private data collections, and consensus models are explained in detail. Practical exercises guide readers through the process of setting up a Hyperledger Fabric network, writing and deploying chaincode, and exploring its modular architecture.

The book also covers Hyperledger Composer, an intuitive development tool designed to simplify and accelerate the creation of blockchain applications on Fabric. Readers will learn how to model business networks, define assets, participants, and transactions, as well as test and deploy their blockchain solutions seamlessly. The hands-on labs in the book are structured to reinforce theoretical knowledge, ensuring a well-rounded understanding of both Fabric and Composer.

By the end of the book, readers will have the skills to structure blockchain-based solutions to tackle real-world business challenges. The book also provides insight into the broader Hyperledger ecosystem, highlighting projects like Sawtooth and Indy, and their respective roles in the blockchain landscape.
