Blockchain-Enabled Secure Data Storage in Decentralized Cloud Environments
Cloud storage has become a popular solution for handling large volumes of data, but its centralized nature raises serious concerns related to security and data privacy. To address these issues, this work presents a decentralized approach using blockchain technology, which eliminates dependency on a single storage authority. In this system, any node connected to the internet can participate in the network, forming a peer-to-peer structure that improves resource utilization and reliability. The proposed model ensures data security by encrypting user files before storage and distributing them across multiple nodes using the IPFS protocol. IPFS generates a unique hash value for each file, which acts as an identifier and is securely recorded on the blockchain. This approach ensures data immutability, transparency, and easy retrieval. Overall, the system provides a secure, efficient, and highly available method for storing data in a decentralized cloud environment.
