Introduction to Cybersecurity Applications in Blockchain Technology

Cybersecurity is a compelling need for all organizations, compounded by rapid technological change and an evolving cyberattack landscape. Many areas have been explored to address the changing security requirements, and one of them is based on blockchain technology. In recent years, blockchain technology has become a top priority for many organizations. Its range of applications (smart contracts, secure transaction recording, peer-to-peer, etc.) has grown rapidly due to its inherent robustness to hackers. In this chapter, we introduce cybersecurity and present its applications in blockchain, as well as provide existing vulnerabilities and potential attacks in the state of the art to perceive the use of cybersecurity in blockchain. We also analyse the main cybersecurity challenges and how they might be addressed through advances in blockchain technology.
