Anonymized, Encrypted, and Decentralized.
We employ edge anonymization on each volunteer device to remove route starts and destinations before submission, keeping all data fully private.
The collected payloads contain anonymous vibration events (G-force metrics recorded at 100Hz from internal mobile accelerometers) paired with scrambled, unconnected GPS coordinates. Researchers can download these blocks to analyze road wear, model infrastructure degradation, and prioritize repairs.
Query the Public Data Repository
Access latest verified telemetry blocks using permissionless API endpoints. Our backend publishes datasets directly to IPFS.
The API returns JSON structures outlining vibration magnitudes, geofenced boundaries, and timestamp coordinates. Below is a sample query to retrieve the latest block.
