Vault3: Decentralized Image Upload and Sharing

Introduction

Vault3 is a blockchain-powered image upload and sharing platform that ensures decentralized, secure, and immutable storage. By integrating IPFS (InterPlanetary File System) and Ethereum smart contracts, Vault3 allows users to upload, manage, and control access to their images without relying on centralized servers.

Features

✅ Decentralized Storage – Uses IPFS for secure and censorship-resistant file hosting.

✅ Smart Contract Access Control – Users can grant/revoke access via Ethereum smart contracts.

✅ Immutable and Transparent – No one can alter or delete files once uploaded.

✅ User-Friendly Interface – Built with React, ensuring an intuitive and smooth experience.

How It Works

1️⃣ Upload Image to IPFS

Users can upload images, which are pinned to IPFS using Pinata API.
🔹 Stores the file on IPFS and returns a CID (Content Identifier).

2️⃣ Smart Contract for Access Control

Users can grant or revoke access to their images using Solidity smart contracts.

🔹 Allows users to upload images, grant access, and revoke permissions.

3️⃣ Fetch Image from IPFS

Users can retrieve images stored on IPFS if they have permission.

🔹 Ensures only authorized users can retrieve and view images.

Why Vault3?

🔹 No Centralized Authority – Full control over your data without intermediaries.
🔹 Tamper-Proof & Censorship-Resistant – Ensures permanent storage and prevents unauthorized modifications.
🔹 Trustless Access Control – Only smart contracts govern permissions.
