As a utility token, FOAM only can provide locational data with Blockchain security for those that use the FOAM token. As the architecture being evaluated currently includes Zone Anchors’ running a Side Chain with either Plasma type, or a hybrid (ZKsnark + Ethereum). The interaction and settlement on mainchain from the sidechain will be with FOAM.
As FOAM is being built from a community governance perspective, your thoughts on using mobile devices to interact with the Protocol would be useful to the overall effort.
I can speculate that we will see details on the Zone Anchor’s design in another month or two. The mechanics of the intra-Zone communication is where the current focus is. The actual requirements for the commodity hardware shortly after. Since all work to this point has focused on established and pre-existing radio and device specifications, I do not foresee there will be a delay in building the first prototypes. I would expect that the initial nodes for the mesh will begin in NYC, with such a densely populated metro area, there will be a huge opportunity to gauge real world results based on those deployed Zone Anchors.
With LoRa frequencies, they are already freely allocated for this type of application, and while not identical worldwide, they are close enough that antennas and IC’s can and have been built to provide overlapping coverage.
In closing, please communicate your End User Mobility requirement to the Community. If you have not already, try gaming (LARPing) out the use cases. I’m wondering if your application can lean more towards end user trust at least to get off the ground… Please look at Crypto-Spatial Coordinates — the open location standard on Ethereum it should give you some insight on what FOAM is building.
