With the growing popularity of Internet-of-Things (IoT) devices in mind, the IoT Refrigerator proof-of-concept demonstrates how these devices can use the speed, small footprint, and flexibility of ChainZy to implement blockchain to track metrics.
ChainZy records the times at which the unit is powered on, the compressor turns on and off, and the fridge doors open and close. Power-outages, mechanical failures, or a door left open can be detected before food goes bad. The following images show the Refridgerator proof-of-concept in action:
A. The fridge powered on with the door closed and the compressor off.
B. The fridge powered on with the door open and the compressor on.
IoT devices are becoming more common, but there is no reliable, indelible method of tracking events and metrics. As more devices are added, recording events will become more expensive.
The proof-of-concept used ChainZy capabilities to track the location, time, and status of simulated refrigerators, including:
ChainZy is designed for easy interfacing and extensibility. The proof-of-concept extended a geolocation feature in browsers to add latitude and longitude coordinates to the blockchain in only 11 lines of code.
ChainZy is made for both new and legacy applications and is easily extendable. It can handle artbitrary data and can be used as a platform for interfacing IoT devices. Its small footprint, low operating overheads, and speed in excess of 500 transactions per second make it IoT ready.
