Decentralized Cloud Storage Architecture Using Block Chain for Data Integrity
Miss. Tafeem · International Journal for Research in Applied Science and Engineering Technology · 2025
Cloud computing offers scalable storage but raises concerns over data integrity and trust due to centralized control. This project presents a decentralized cloud storage system using blockchain to ensure secure, transparent, and tamper-proofdata handling. By integrating cryptographic hashing, smart contracts, and audit logging, the system allows users to verify data integrity without third-party auditors. Implemented with ASP.NET and C#, the prototype demonstrates secure uploads, controlled access, and verifiable audit trails, forming a foundation for future blockchain-enabled cloud systems.
