A review on blockchain impact on in cybersecurity: Current applications, challenges and future trends

The potential for blockchain to transform several industries, including cybersecurity, has piqued the interest of many different sectors. This abstract delves into the relationship between blockchain and cybersecurity, showcasing how the two may work together to strengthen data security. The present cybersecurity scenario prompted this study to examine existing blockchain-based security solutions. In this study, we looked at the ways blockchain technology maintains the security triangle. The results show that blockchain has a lot of promise for solving current cybersecurity problems, especially with IoT, data ownership and integrity, and network security. However, high-cost complexity, regulatory barriers, and technology immaturity all hinder wider implementation. As a result, using blockchain-based solutions in cybersecurity requires careful consideration of how well they apply to the particular requirements of an organisation, as well as the establishment of precise implementation objectives and the navigation of potential obstacles. This pertinent systematic review sheds light on several subjects that should be explored further as fields for cyber and blockchain security research, education, and practice, including blockchain security in the IoT, blockchain security for AI data, and sidechain security.
