Internet of Things (IoT) Data
A data creator wants to record temperature values on the blockchain, so that anyone can view them at any time and the data is fully transparent.
An IoT device is used to monitor the temperature. Every hour, a temperature reading is taken by the device and the resultant temperature, the device ID, the geo-location, and the datetime are appended to the blockchain using nChain Event.
The resultant location on the blockchain is published by the data creator, and anyone can view the data.
Benefits
Proof of Publishing: Immutable proof of the exact data generated by an IoT device and the time it was created.
Transparency: Anyone can inspect and confirm the legitimacy and timestamp of the IoT data.
Returned location can be looked up in a blockchain reader.
