🛡️ Decentralized-X

A decentralized social media application built on Ethereum that combats misinformation using blockchain verification, IPFS content storage, a reputation-based validator network, and community-driven consensus.

---

📌 Overview

This project demonstrates how decentralized technologies can be harnessed to tackle misinformation at its roots by:

• Verifying media originality and provenance via IPFS + smart contracts
• Empowering a reputation-based consensus system to validate reported content
• Providing transparency, traceability, and community governance for social media

---

🔧 Prerequisites

• Node.js (v16 or later)
• NPM
• Metamask wallet (connected to Sepolia Testnet)

---

📁 Project Structure

• PostContract.sol: Handles post creation, hash lookup, user registration, and engagement (likes/dislikes).
• Misinformation.sol: Manages report mechanisms, validator consensus, and on-chain reputation updates.
• frontend/: Contains the React.js frontend for interacting with the blockchain and IPFS.

---

🔐 Smart Contract Details

📝 PostContract.sol

Manages:

• User registration/login
• Post creation with IPFS hash
• Original/sourced detection
• Likes/dislikes

🚨 Misinformation.sol

Manages:

• Reporting & flagging logic
• Validator-based voting system
• On-chain reputation for validators/reporters
• Reward/penalty via consensus

🚀 Getting Started

1. Clone the repository

git clone https://github.com/thatayushmallick/decentralized-x.git
cd decentralized-x

2. Install Dependencies

Run the commands :

cd frontend
npm i

3. Configure Metamask wallet

• Ensure your Metamask is connected to Sepolia with test ETH
• Test ETH can be obtained from sources like https://cloud.google.com/application/web3/faucet

4. Compile Smart Contracts (Optional)

• Upload the smart contracts PostContract.sol and Misinformation.sol on Remix IDE.
• Compile the smart contract Misinformation.sol.
• Set environment as Sepolia Testnet on Remix IDE.
• Deploy the smart contract.
• Copy the contract ABI and contract address and paste them in frontend/src/contract.js.

5. Start Development Server

Run the command :

npm start

Open http://localhost:3000 in your browser.

Note : Ensure your Metamask is connected to Sepolia with test ETH.
