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.

Summary

In this chapter, we have examined the most delicate aspects regarding compliance with privacy requirements in the context of the processing of sensitive data carried out through blockchain. We have dealt with various aspects regarding the use of blockchain in the healthcare sector, and the critical issues associated with the growing diffusion of IoT technologies adopted in managing medical data. We also analyzed the possible advantages offered by the adoption of the blockchain to mitigate the vulnerabilities of IoT devices. Finally, we dealt with compliance issues with the GDPR, analyzing the main aspects of the EU legislation that are difficult to apply within the blockchain.

Congratulations! You have come to the end of a demanding path that has led you to greater awareness of securing blockchain. We hope you enjoyed your reading!
