¶ Encrypted Messaging PoC - Overview
Complete system architecture showing the peer-to-peer messaging infrastructure with blockchain integration and IPFS storage
A production-ready peer-to-peer messaging system built on Sonic blockchain with end-to-end encryption and file attachment support.
¶ 🎯 Project Summary
The Encrypted Messaging Proof of Concept demonstrates a complete decentralized messaging platform that enables secure, private communication between wallet addresses on the Sonic blockchain. The system combines blockchain immutability with client-side encryption to provide censorship-resistant messaging with optional file attachments.
🚀 PRODUCTION STATUS: 100% Ready for Mainnet Deployment
¶ ✨ Key Features
¶ 🔐 End-to-End Encryption
- Client-side encryption using CryptoJS AES-256-CBC
- Recipient-specific encryption ensuring only intended parties can read messages
- Content hash verification for message integrity
- Private key-based decryption maintaining user privacy
¶ 📎 File Attachment Support
- Large file handling (tested with 1.3MB+ files)
- IPFS integration for decentralized file storage
- Metadata encryption protecting file names and details
- Cost-efficient storage with hybrid on-chain/off-chain architecture
¶ ⛓️ Blockchain Integration
- Sonic blockchain deployment with excellent performance
- Smart contract written in Solidity with OpenZeppelin security
- Gas optimization through efficient storage patterns
- Event-driven architecture for real-time updates
¶ 🌐 Web3 Frontend
- React/Next.js application with TypeScript
- Wallet connectivity via RainbowKit and Wagmi
- Responsive design with modern UI components
- Real-time messaging with blockchain event listening
¶ 🚀 Real-World Implementation
⭐ PRODUCTION-READY STATUS: The system is now 100% ready for production deployment
This is not just a proof of concept - it's a fully functional, production-ready messaging system that has been thoroughly tested and validated. Key achievements:
