The growing adoption of cloud computing has introduced unprecedented scalability and flexibility to digital operations but has also exposed users to heightened cybersecurity threats, including data breaches, unauthorized access, and loss of control over critical information. This paper explores how blockchain technology can serve as a robust solution to these challenges by enhancing trust, transparency, and security in cloud environments. Specifically, the study examines blockchain’s decentralized architecture, cryptographic techniques, and immutability as mechanisms to address core vulnerabilities in traditional cloud systems. The paper reviews various blockchain-based cybersecurity models—such as smart contract-based access control, decentralized identity management, and tamper-proof audit trails—and evaluates their effectiveness in real-world scenarios. Through comparative analysis and recent case studies, the findings demonstrate that blockchain not only strengthens data integrity and user authentication but also reduces reliance on centralized authorities that often-become single points of failure. However, the paper also acknowledges the scalability, energy consumption, and interoperability challenges that must be addressed before widespread implementation. In conclusion, the integration of blockchain technology into cloud computing infrastructures presents a promising pathway toward more secure, resilient, and autonomous digital ecosystems. The paper advocates for continued research and cross-industry collaboration to optimize blockchain frameworks for cloud-specific applications and to establish standardized protocols for broader adoption.
