Proof Of Location protocol

[g0rlitzer]

Hello guys,
since I red FOAM "introduction to PoL" (https://blog.foam.space/introduction-to-proof-of-location-6b4c77928022) i wonder about its application.
From what i understood the real factor to obtain a specific and meticulous position signal is the merging of (at least) 4 "zone anchors" (miner-knots) based on sync time.
Those operators join a smart contract that enables to earn a reward for nodes activity (so called Service Level Agreements).
First of all tell me if i misunderstood the article or the compliant technology. So is this protocol capable of trackign only x and y coordinates?
D you think is a good choice to lay on ethereum chain or it would be better to build a propretary one?
It seems to me an huge possibility for privates to build a proper owned "sonar"(maybe this isn t a good similitude)  that, meshed and linked with other's ones, will  track every device even indoor!

You can get all three x y and z from only three "zone anchors" - it will just be less accurate than four.

They aren't tracking the "z" coordinate in the traditional sense of the third spatial dimension. They are calling their 'smart contract suite' as the "z-coordinate" which is confusing. Ultimately, they are only tracking things on the surface, so just x and y coordinates. They then allow you to build as many smart contracts on this single (x,y) location as you want, each one getting a 'unique z coordinate' so the smart contracts are kept separate.

Thanks,
So I was right.. the "z coordinate" works as an unique identifier and nothing else. Another point i wish to understand relates to the indoor spacing location: just with a beacon signal system how is possible to map the real zone without a visual feedback? I mean it seems to me that this protocol would be suitable whether joined with the GPS protocol ( this one would provide a general context and the foam protocol would assure the right location)
