Abstract : This study explores the design and implementation of blockchain-backed storage for cloud computing in the Web 3.0 era, focusing on hybrid architectures that combine traditional cloud storage with decentralized blockchain layers. Using Filecoin and Arweave as representative case studies, the work analyzes system models, data upload mechanisms, consensus validation, cost structures, and reliability frameworks. Empirical datasets from 2023 to 2025 highlight trends such as growing utilization, declining storage costs, and near-perfect reliability metrics. Correlation matrices and regression forecasts further demonstrate strong relationships between adoption, cost reduction, and network growth. Results show that decentralized storage is not only technically viable but also economically competitive, offering scalable, secure, and censorship-resistant alternatives to centralized providers. The findings emphasize the role of blockchainbacked storage in enhancing data sovereignty, resilience, and transparency for digital economies transitioning toward Web 3.0.
