Ndani
Trustless Privacy Infrastructure
Ndani (Swahili: "inside" — inside-out trustlessness)
Ndani is the hardware architecture that eliminates the final privacy vulnerability: the trusted gateway.
Core Thesis
Anonymity requires device-held keys. Trustless privacy requires farmer-owned proof infrastructure.
The Gateway Problem
Traditional Approach:
Sensor → Gateway (Trusted) → Proof → Chain
↑
PRIVACY FAILURE POINT
(sees identity, raw data)
Ndani:
Sensor → Local Pi 5 (Farmer-Owned) → Proof → Chain
↑
OWNER ALREADY HAS ACCESS
No new trust required
By moving proof generation to farmer-owned infrastructure, privacy holds against all external observers, government, corporate, network.
Hardware Stack (~$163)
| Layer | Component | Cost |
|---|---|---|
| Sensor | ESP32-S3 + ATECC608A + LoRa + sensors | $38.50 |
| Proof | Raspberry Pi 5 + infrastructure | $115.00 |
Beyond Privacy: Economic Autonomy
Ndani enables devices as autonomous economic agents with ZK-enforced spending policies, mathematically bounded autonomy.
Even a compromised device cannot exceed its spending policy.
Status
Research phase. Targeting USENIX Security venue.
