Blockchain Technology: Enhancing Security in a Decentralized World
Marwan Omar · 2025
In the context of cybersecurity, blockchain technology has lent a new form and meaning in ensuring security, credibility, and veracity in networked and decentralized environments. While conventional, centralized systems continue to pose numerous cyber risks, blockchain incorporates a new essential approach to protecting data, facilitating trustless transactions, and guaranteeing its tamper-proof nature. This chapter thus examines the key components that make up the blockchain platform; these include hashes, consensus models, and decentralized structures. It underscores how blockchain enhances safety in several industries, eradicating risk weaknesses, yet combining authority within the management of data. This chapter, by touching on various cases and a thorough analysis, provides evidence of the fact that blockchain may reshape the future of cybersecurity and its application in preventing novel threats.
