All Use Cases
IoT Data Integrity & Provenance
Guarantee the integrity and timestamp of IoT sensor data for regulatory, safety, or contractual purposes. Cryptographic proof that data hasn't been tampered with.
The Challenge
- Sensor data can be altered after collection, undermining trust
- Regulatory compliance requires proof of data authenticity
- Disputes over readings lack verifiable timestamps
The Solution
- Immutable storage ensures readings can't be modified
- Cryptographic timestamps prove when data was recorded
- Verification API allows third-party validation
Common Applications

Manufacturing QA
Tolerance measurements and defect detection logs.
Energy Metering
Consumption readings for billing and compliance.
Medical Telemetry
Patient monitoring device data for healthcare records.
Cold Chain Compliance
