A private home node for diabetic life.
Local records. · Smart reminders. · Trusted support.
Privacy first. Not as a setting — as the foundation. A diabetic node is sovereign compute pointed at one job: helping a diabetic, on hardware we own, with their private health data never leaving their box. Every choice below — the GPUs, the storage, the edge — exists to keep that true. DiabeticNode is the honest, hardware-by-hardware breakdown of what runs where, and why.
🐝 It takes a swarm to run the node. No single device does the job — the hive cooks, the vault holds, the edge runs, the wearables reach you. Six limbs, one node.
Three tiers, one law. LIVE = running & verified · IN BUILD = partly done · FRAMEWORK = designed, not yet a service. No vaporware, no black box.
Private health data never leaves the box. Models flow down, receipts flow up, PHI crosses never. Every hardware choice below exists to honor that law. → The Firewall
Privacy-first only means something if it's structural. On a diabetic node it's enforced by how the hardware is wired, not by a policy you have to trust:
| Guarantee | How the hardware enforces it |
|---|---|
| Records never leave | PHI lives only on the Synology vault on the home network; the cloud has no path to raw records |
| Inference stays local | the Jetson Orin edge brain runs the model on-box; queries never round-trip to a cloud |
| No PHI at rest off-box | the edge brain processes records in RAM only and persists none |
| Only non-PHI crosses | devices receive generic nudges; the hive receives receipts — never records |
| Everything is provable | every action mints a hash-chained, non-PHI receipt — auditable without exposing data |
| Tier | Hardware | Job | Status |
|---|---|---|---|
| The Hive (cook) | RTX PRO 6000 Blackwell GPU fleet | Slow-cook the diabetic models on owned silicon. Models flow down from here. | IN BUILD |
| The Vault (store) | Synology NAS boxes | Hold the diabetic's records — the only place PHI lives at rest. Filing cabinet, not a cloud. | LIVE |
| The Edge (run) | Jetson Orin + consumer devices | Run the model on-box; reach the diabetic via watch, phone, sensors, voice. | LIVE |
→ The Fleet breaks down the cook + vault hardware (why Blackwell, why Synology). → The Edge breaks down Jetson Orin and the real-world devices (Apple Watch, iPhone, IoT sensors, Home Advisor, Whisper).
