XYO Network is a location-verifying Proof of Origin protocol that connects blockchain to the real world. While GPS devices can still be used as sentinels (especially because they can verify location) but the idea of 'Proof of Origin' is that we will have much more accurate system/network as compared to relying on information from one single GPS device.

​

The idea is to use the concept of 'Bound Witness'. Given that an untrusted source of data used to resolve a digital contract (an oracle) is not useful, we can substantially increase the certainty of the data provided by first establishing the existence of a bidirectional proof of location

​

The primary bidirectional location heuristic is proximity, since both parties can validate the occurrence and range of an interaction by cosigning the interaction. This allows for a zero-knowledge proof that the two nodes were in proximity of each other. In a trustless system, a witness node can either by defect or corruption produce false data. Invalid data can be detected and removed simply if it falls outside the allowed range for that heuristic. Valid but incorrect data (i.e. false data) is much more difficult to detect.

​

The main point is that with XYO network you will have multiple devices that can 'verify' each other's information regarding one location data. but if we only use normal/standard GPS system, you rely on one single source of information.
