B-Drive — Decentralized Cloud Storage on Web3

B-Drive is a decentralized storage application inspired by Google Drive — built for ETHOnline 2025 using Scaffold-ETH 2, Next.js, and IPFS/Lit Protocol.
It allows users to securely upload, view, and manage files using blockchain technology, ensuring privacy, ownership, and censorship resistance.

🧠 Overview

Traditional cloud storage systems rely on centralized servers that can be censored, hacked, or misused.
B-Drive solves this by leveraging IPFS and Ethereum smart contracts to create a fully decentralized, censorship-resistant storage platform.

Every file is:

• Encrypted and uploaded to IPFS via Lighthouse SDK
• Linked to a user’s Ethereum wallet address
• Managed by a smart contract for ownership, tracking, and deletion This makes file management:

⚠️ Note: The upload feature may not work because of the limited trial period of LightHouse SDK
