XYO is a blockchain oracle— an interface layer between smart contracts and the physical world. It is a hardware-agnostic verification network that runs on IoT devices, sensors, and smart phones. XYO's Proof of Origin and Bound Witness protocol ensure high-certainty sensor data like temperature, humidity, location, pressure, etc. for smart contracts to interact with. XYO is creating a global mesh-network of sensors interacting and transmitting data amongst each other. The major goal of our network is to implement a proof of interaction protocol which can be used to identify who interacted with whom, and even where specific interactions took place on the globe.
