BlocX is a decentralized blockchain-powered social media platform that combines Web3 technologies, AI moderation, smart contracts, decentralized storage, and governance voting into a modern social networking ecosystem.

The project aims to address common issues in traditional social media platforms such as:

• Centralized control
• Privacy concerns
• Data manipulation
• Fake accounts
• Lack of transparency
• Content ownership problems

BlocX integrates blockchain technology with AI-powered moderation and decentralized governance to create a secure and transparent platform for users.

• MetaMask wallet-based authentication
• Secure cryptographic signature verification
• Wallet connect/disconnect support
• User profile management

• Create, edit, and delete posts
• View personalized feed
• Like, comment, and share posts
• Multimedia content support

• Media files stored using IPFS
• Blockchain stores immutable IPFS hashes
• Decentralized ownership tracking

• Smart contract-based transaction recording
• Immutable blockchain records
• Transparent activity tracking
• Ownership verification

• AI-based content moderation
• Spam and harmful content detection
• Fake account detection
• Personalized recommendation system

• DAO-style governance voting
• Community proposal management
• Transparent vote tracking
• Blockchain-inspired voting logic

• Token reward distribution
• Engagement-based incentives
• Blockchain reward transactions

IPFS Storage + AI Moderation System

Users authenticate securely using MetaMask instead of traditional username/password systems.

Users can:

• Create posts
• Upload media
• Interact with content
• Manage posts

AI models analyze content to:

• Detect spam
• Filter harmful posts
• Identify fake accounts
• Improve platform quality

Smart contracts handle:

• Transaction recording
• Token rewards
• Governance voting
• Ownership tracking

Users participate in decentralized governance through proposal voting mechanisms inspired by DAO systems.
