zkIoT

zkIoT enables IoT devices to prove compliance without exposing raw data, combining Zero-Knowledge Proofs with sensors to foster trust, privacy, and secure industrial insights.

Project description: 

zkIoT is a framework that enables IoT devices to prove compliance with rules or thresholds without revealing raw sensor data. By applying Zero-Knowledge Proofs (ZKP) to physical sensor outputs, industries can unlock trust and data usability while protecting privacy, trade secrets, and operational know-how. 

Problem

• Data exposure risk: Over 70% of IoT data leaks involve sensitive operational or personal details, discouraging adoption in critical sectors.
• Economic impact: Global IoT data breaches are projected to cost industries more than $500B annually by 2030, with healthcare and energy as the most affected.
• Adoption barrier: Surveys indicate that 60% of enterprises delay IoT rollouts due to privacy, liability, and IP protection concerns, limiting innovation in trillion-dollar markets.

Solution

zkIoT bridges physical sensors and blockchain verification through:

1. Zero-Knowledge Proofs – Devices prove compliance ("temperature within 2–8°C", "energy ≤ X kWh") without revealing raw logs.
2. Secure IoT Device Layer – Hardware-secured IDs and signed data ensure authenticity of sensor input.
3. Trusted Communication – TLS/MQTT pipelines commit encrypted sensor data, while only ZK proofs flow on-chain.

• Under-collateralized Industrial Lending × IoT Production Proof.
• IoT-based Whitelisting for EV Charging & Smart Mobility.
