I have recently been introduced to the many use-cases for blockchain technology. One of the examples that Russ Fustino mentioned was the storage of sensor data for the automotive industry.
If all data is publicly available, I foresee many instances where the manufacturer may not want this sensor data to be accessible without authorization. Is there a way to securely encrypt this data or store privately/ externally?
More generally speaking, should personal data (emails, names, etc) remain off of the blockchain all together?
