Why sovereign infrastructure matters

Every packet that leaves your network is a dependency. Every cloud service is a single point of failure. We built BlackRoad OS to eliminate both — a fully distributed system that runs on hardware you physically control.

The best infrastructure is the kind you can hold in your hand and reflash in five minutes.

The architecture

Our mesh connects five Raspberry Pi 5 nodes across a local network, each serving a specific role in the cluster. WireGuard provides encrypted tunnels between all nodes, and Cloudflare tunnels handle external routing.

# WireGuard mesh topology
alice    10.8.0.6   # Gateway, Pi-hole, PostgreSQL
cecilia  10.8.0.3   # AI inference, TTS, MinIO
octavia  10.8.0.4   # Gitea, NVMe storage, Docker Swarm
aria     10.8.0.7   # Portainer, Headscale
lucidia  10.8.0.5   # APIs, web apps, DNS

Self-healing with autonomy scripts

Each node runs heartbeat checks every minute and healing scripts every five minutes. If a critical service goes down, the node restarts it automatically and logs the event.

Hardware acceleration

Two nodes carry Hailo-8 AI accelerators, providing 52 TOPS of neural network inference at the edge. This powers local LLM inference, computer vision, and TTS without any cloud dependency.

What we learned

Power management is everything on Pi hardware. We implemented CPU governor tuning, swap optimization, and thermal monitoring across the fleet. The result: stable temperatures under 60°C even under sustained AI inference loads.
