Why Choose This Project?

Traditional cloud storage platforms rely on centralized servers, making data vulnerable to hacks, data loss, and privacy breaches. This blockchain-based decentralized file storage system uses IPFS for distributed storage and smart contracts for secure access control, ensuring that files are tamper-proof, encrypted, and only accessible by authorized users. Users can store, share, and track their data securely without intermediaries.

Features That Make It Market-Ready

• Decentralized File Storage – Files stored on IPFS across multiple nodes, preventing single-point failures

• Wallet-Based Authentication – Login via MetaMask; secure and passwordless

• Smart Contract Access Control – Only authorized users can access or download files

• File Upload & Retrieval – Upload files, generate IPFS hash, and retrieve securely

• Permission Management – Grant or revoke access to specific users

• Optional Payment Integration – Pay per storage or download via smart contracts

• Immutable Records – All file upload, sharing, and access events recorded on blockchain

• Dashboards for Users & Admins – Manage files, monitor access logs, and track storage usage

Working Flow

1. User Connects Wallet
   → Login via MetaMask

2. File Upload
   → User uploads file
   → File stored on IPFS → returns unique hash
   → Metadata (filename, owner, permissions) stored on blockchain

3. Access Control
   → Owner grants or revokes access to other users
   → Smart contract enforces permission rules

4. File Retrieval
   → Authorized users request file
   → IPFS hash verified via blockchain → secure download

5. Optional Payment Flow
   → Payment locked in smart contract (if required)
   → Released upon successful access or download

6. Immutable Records
   → All uploads, shares, access events recorded on blockchain

7. Dashboard Update
   → Users and admins see file history, access logs, and storage stats
