Blockchain Technology-Based Improvements to Cybersecurity

Abstract

Decentralized public ledger blockchain secures transactions across untrusted network nodes. Bitcoin systems rely on it to safeguard and decentralize transaction records, attracting attention. Over the last decade, blockchain has garnered interest from numerous businesses because of its potential to transform multiple areas, including cybersecurity. This research area is new, and blockchain's cybersecurity efficacy has to be addressed. This qualitative study examines blockchain-based security applications and their suitability in the current cybersecurity environment. A single point of failure may expose a centralized administration and validation system to malware, Distributed Denial of Services (DDoS), and Denial of Services (DoS) assaults. Blockchain technology creates secure, private decentralized networks without third-party control. Blockchain allows irreversible and verifiable storage of current and historical data in a sealed ledger distributed throughout the network. Blockchain technology distributes encrypted data throughout the network, improving data security and privacy. A decentralized e-government peer-to-peer system employing blockchain technology to secure and anonymize data and boost public sector credibility is proposed in this research. The suggested system's security and privacy consequences are theoretically and qualitatively analyzed, along with a prototype.
