A private home node for diabetic life.

The crystal-clear breakdown of diabetic compute

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.

The one law

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 — by construction, not by promise

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:

GuaranteeHow the hardware enforces it
Records never leavePHI lives only on the Synology vault on the home network; the cloud has no path to raw records
Inference stays localthe Jetson Orin edge brain runs the model on-box; queries never round-trip to a cloud
No PHI at rest off-boxthe edge brain processes records in RAM only and persists none
Only non-PHI crossesdevices receive generic nudges; the hive receives receipts — never records
Everything is provableevery action mints a hash-chained, non-PHI receipt — auditable without exposing data

The three tiers of a diabetic node

The Hive (cook)RTX PRO 6000 Blackwell GPU fleetSlow-cook the diabetic models on owned silicon. Models flow down from here.IN BUILD
The Vault (store)Synology NAS boxesHold the diabetic's records — the only place PHI lives at rest. Filing cabinet, not a cloud.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).

Why sovereign — why we own the silicon

Why we own it: a diabetic's health data is the most personal data there is. You cannot rent that trust from a cloud. We own the GPUs, the storage, and the edge boxes — so PHI has no reason to ever leave, our marginal cost is just kilowatt-hours, and every claim is verifiable on hardware we control. Sovereign isn't a buzzword here; it's the only way the one law can be true.
