The problem the god sensor solves
In a world increasingly dependent on automated decision-making, we lack a Verifiable Truth Layer for real-world data.
Centralization Risk: Current IoT and sensor networks rely on centralized APIs that can be manipulated.
Privacy vs. Utility: Proving a location or a climate reading shouldn't require exposing the exact device metadata.
DePIN Scalability: Current "Proof of Physical Resilience" systems are often clunky and expensive to settle on-chain.
GodEye solves this by generating ZK-Proofs at the edge, signing them via Orbitport Satellites for absolute timestamping, and settling them on Ethereum for sub-cent costs.
Challenges we ran into
Noir Integration: Compiling complex circuits for tiny edge devices required significant optimization of the ZK-pipeline to fit within enclave memory constraints.
Satellite Latency: Implementing a robust "retry" logic for the Orbitport KMS signing loop to handle transient satellite connectivity.
On-chain Settlement: Balancing the 5-minute uptime requirement with Ethereum's block times—we solved this by implementing a "batch verification" system in the manager contract.
Gas Optimization: Minimizing the cost of reward minting while maintaining a strict on-chain record of every verified proof.
