Securing Blockchain Networks like Ethereum and Hyperledger Fabric

By: Alessandro Parisi

Overview of this book

Blockchain adoption has extended from niche research to everyday usage. However, despite the blockchain revolution, one of the key challenges faced in blockchain development is maintaining security, and this book will demonstrate the techniques for doing this. You’ll start with blockchain basics and explore various blockchain attacks on user wallets, and denial of service and pool mining attacks. Next, you’ll learn cryptography concepts, consensus algorithms in blockchain security, and design principles while understanding and deploying security implementation guidelines. You’ll not only cover architectural considerations, but also work on system and network security and operational configurations for your Ethereum and Hyperledger Fabric network. You’ll later implement security at each level of blockchain app development, understanding how to secure various phases of a blockchain app using an example-based approach. You’ll gradually learn to securely implement and develop decentralized apps, and follow deployment best practices. Finally, you’ll explore the architectural components of Hyperledger Fabric, and how they can be configured to build secure private blockchain networks. By the end of this book, you’ll have learned blockchain security concepts and techniques that you can implement in real blockchain production environments.

Getting to know Hyperledger Fabric

Hyperledger Fabric is a permissioned blockchain managed by a consortium of companies. The project has been hosted and promoted by the Linux Foundation since December 2015, since the Linux Foundation together with 30 sponsoring companies (including IBM) decided to create an enterprise-class open source blockchain. Other major companies of the caliber of Intel, Accenture, and Huawei have subsequently joined the project, and their number currently exceeds 250 members.

Hyperledger Fabric is designed to provide high flexibility and extensibility, both at an architectural and application level. The modular architecture extends to the consensus mechanism, thus allowing specific consensus algorithms to be adopted on the basis of the different use cases, simply by choosing the most suitable component to implement the consensus mechanism of choice.
