I'm not sure why that matters. By inputting coordinates, you have giving extra information. There is a difference between verifying that someone knows the coordinates and sharing the actual coordinates.
This particular system seems to function like an IDP. Where, upon authentication and token is issued, and the 3rd party checks the token's validity. I'm not sure that is the same as zero-knowledge.
- mattdesl 5y agoThe project can be downloaded and run locally (it is a static client side website, no server) and the proof generation and verification can be run offline, without the coordinates ever being sent over the network. Only the proof file needs to be sent between the two parties. I suppose the system itself acts as a “third party” but at no stage does it require you to share the coordinates with one another, hence zero knowledge. :) Does that make sense?
