In the context of “supplanting the GPS” narrative, is there any data on the expected accuracy of PoL? GPS with RTK correction can get you to centimeter accuracy; would be nice if FOAM network provided at least that much.
I also wonder about the latency at which FOAM zones would be able to localize clients. When talking of proof of location, this, of course, will depend on blockchain’s block mining schedule (so, 10s of seconds with Ethereum 1.0). What about ways to consume FOAM localization service in a more real-time (and perhaps less confirmed) fashion, do you foresee any? Consider a self-driving vehicle navigating dense urban environment; GPS signal is particularly unreliable in those. Such vehicle may need an occasional proof of location too, but what it could really use is a reliable low-latency positioning data.
