QuantDog

Inspiration

The looming quantum threat to cryptography motivated us to build a proactive solution. With quantum computers projected to break current encryption within 5-10 years, over $2.25 trillion in cryptocurrency assets face immediate risk, yet 95% of crypto exchanges and wallets remain unprotected.

What it does

QuantDog is an intelligent quantum threat detection platform that deploys honeypot wallets across blockchains as early warning sensors, monitors threats in real-time, and automatically switches between classical and post-quantum encryption based on threat levels to preserve speed when there is no threat expected.

How we built it

• Frontend: React 19 with TypeScript, TailwindCSS v4, shadcn/ui components, and Three.js for 3D visualizations
• Backend: Python with FastAPI for high-performance APIs and async operations
• Real-time Communications: WebSocket connections for live threat monitoring and instant updates
• Cryptography: Post-quantum cryptography implementation with NIST-compliant algorithms
• Infrastructure: Docker containerization and Terraform for cloud deployment
• Network Layer: TUN/TAP interfaces for packet capture and cryptographic routing

Challenges we ran into

Our biggest challenges included implementing packet interception with TUN/TAP interfaces in Docker, getting post-quantum cryptography KEM working over networks, and deploying complex infrastructure with Terraform while building algorithms to distinguish normal blockchain activity from quantum attacks.

What we learned

Cryptographic algorithms across all sectors are in serious trouble once quantum computing reaches anticipated levels in 5+ years. We discovered the "harvest now, decrypt later" threat is already real, and there's a massive untapped market opportunity for quantum-safe solutions in the vulnerable crypto space.
