Overview of this book

Blockchain with Hyperledger Fabric - Second Edition is a refreshed and extended version of the successful book on practical Hyperledger Fabric blockchain development. This edition includes many new chapters, alongside comprehensive updates and additions to the existing ones. Entirely reworked for Hyperledger Fabric version 2, this edition will bring you right up to date with the latest in blockchain. Using a real-world Trade Finance and Logistics example, with working code available on GitHub, you’ll really understand both how and why Hyperledger Fabric can be used to maximum effect. This book is your comprehensive guide and reference to explore and build blockchain networks using Hyperledger Fabric version 2. This edition of the book begins by outlining the evolution of blockchain, including an overview of relevant blockchain technologies. Starting from first principles, you’ll learn how to design and operate a permissioned blockchain network based on Hyperledger Fabric version 2. You will learn how to configure the main architectural components of a permissioned blockchain network including Peers, Orderers, Certificate Authorities, Channels, and Policies. You’ll then learn how to design, develop, package, and deploy smart contracts, and how they are subsequently used by applications. This edition also contains chapters on DevOps, blockchain governance, and security, making this your go-to book for Hyperledger Fabric version 2.

Programming language

As we discovered earlier in the chapter, at the heart of Hyperledger Fabric is an immutable log of multi-party transactions. This idea transcends any given programming language; indeed, we'd really like as many participants as possible to participate in a network of multi-party transactions.

Moreover, given we have a decentralized system where different organizations develop different smart contracts and applications, it's just not feasible to suggest that only one programming language can be used.

This joint desire and need for language openness is why Hyperledger Fabric allows multiple programming languages to be used for smart contract and application development. At the time of writing, the most popular programming languages are JavaScript, TypeScript, Java, and Golang, and support for these is built into Fabric. Additionally, the Hyperledger Burrow project allows developers to write smart contracts in Solidity, a programming language used...
