Abstract
The integration of distributed ledger technologies (DLTs) into multi-cloud environments presents a transformative approach to addressing data integrity and transactional security challenges in modern digital infrastructures. This review comprehensively examines the intersection of multi-cloud computing and distributed ledger systems, highlighting their potential to provide decentralized, tamper-proof, and transparent data management solutions across diverse cloud platforms. The paper explores key architectural frameworks, consensus mechanisms, interoperability protocols, and cryptographic models that enable seamless integration while ensuring scalability, reliability, and enhanced security. Furthermore, it analyzes current use cases, such as supply chain management, financial services, and healthcare, where multi-cloud DLT integration mitigates risks of single points of failure, data breaches, and unauthorized access. By identifying emerging trends, technological limitations, and research gaps, this review offers valuable insights into optimizing multi- cloud DLT deployments for robust data integrity and secure transactional processes. The study underscores the growing importance of cross-cloud blockchain interoperability and regulatory compliance in advancing secure and resilient multi- cloud ecosystems.
