Blockchain for the IoT: Privacy-Preserving Protection of Sensor Data

The paper proposes a design theory (requirements, principles, and features) for a blockchain-based sensor data protection system that certifies IoT data, ensuring tamper-resistant, privacy-preserving, scalable and efficient data gathering, processing and exchange, demonstrated with the CertifiCar instantiation.
