🏁 PitLink PQC — Smart File Transfer System

Quantum-Safe, Latency-Resilient Data Fabric for the Next Era of Engineering Mobility

💡 Inspiration

In Formula 1, milliseconds matter.
Each car streams over 1.5 TB of telemetry, video, and simulation data per race weekend — yet racetrack connectivity remains volatile.
A single drop in the 5G link can cost crucial performance insights.

We were inspired by the way F1 engineers, edge AI labs, and field researchers battle against unstable networks every day.
Our goal was to build something universal — a self-healing, post-quantum-secure file transfer layer that guarantees data integrity, low latency, and resilience, even when the network collapses.

So, we built PitLink PQC — a fast, resilient, and quantum-safe transfer fabric that can securely sync critical data between racetrack and factory, rural lab and cloud, or drone fleet and control room.

⚙️ What It Does

PitLink PQC is a smart file transfer system that ensures high-speed, tamper-proof data flow over unreliable connections — 5G, Wi-Fi, or satellite.

It automatically:

Splits and hashes files into verifiable chunks (BLAKE3 + Merkle tree)
Encrypts everything using post-quantum cryptography (ML-KEM + AES-GCM)
Schedules priorities (P0–P2) using Weighted Fair Queuing + Earliest Deadline First
Auto-recovers from packet loss and reorders packets seamlessly
Predicts link failures using ML-based telemetry (RTT, jitter, loss rate)
Logs every action into immutable, auditable storage for compliance and traceability

In short:
It guarantees that data always arrives fast, whole, and secure — no matter how unstable the network is.

🏗️ How We Built It

We designed PitLink PQC as a layered modular system, with adaptability inspired by F1 telemetry stacks and enterprise-grade edge computing.
