FOAM
Open Protocol for Proof of Location on Ethereum
FOAM is an open protocol for proof of location on Ethereum. Our mission is to build a consensus driven map of the world, empowering a fully decentralized web3 economy with verifiable location data. FOAM incentivizes the infrastructure needed for privacy-preserving and fraud-proof location verification. The starting point for FOAM is static proof of location, where a community of Cartographers curate geographic Points of Interest on the FOAM map. Through global community-driven efforts, FOAM’s dynamic proof of location protocol will enable a permissionless and privacy-preserving network of radio beacons that is independent from external centralized sources and capable of providing secure location verification services.
FOAM incentivizes a distributed network of beacons with radio transceivers, called Zone Anchors, to be deployed. The first step in joining the network is sending signals to connect with and discover nearby Zone Anchors.
Proof of Location depends on accurate and synchronized clocks. Zone Anchors send messages until a consensus can be formed on the precise time. The timed difference of messages sent and received allow for location to be calculated and the geometry of the network to be determined. We rely on a Byzantine Fault tolerant clock synchronization protocol.
Once synchronized, groups of Zone Anchors can establish a Zone and pledge to offer location services that are enforced by smart contract safety deposits, which provide accountability to faulty behavior. A Zone maintains a quorum on Time and Space.
Zones can include time stamped messages from customers in a competitive market for a transaction fee. This is done while Zones are resynchronizing clocks and publishing their time logs to a data store. Validators provide fraud proofs and calculate Triangulations for precise location data to verify final Presence Claims.

The FOAM Proof of Location protocol empowers a permissionless and autonomous network of radio beacons that can offer secure location services independent of external centralized sources such as GPS through time synchronization.
Interesting project with a pretty neat idea. Am looking forward to the implementation. Only hard part will be the implementation and adoption but if all else works, will be a pretty massive project.

Very interesting idea that can totally use a blockchain technology implementation. Their idea of a location protocol based on the Ethereum network is very unique. Good luck team!

I like the idea behind this project, as it addresses the main principles that blockchain was built on: decentralization and privacy.
I will closely follow the evolution of this project, as its idea intrigues me.
Rated the team with a 4 as I see no LinkedIn links on the website.
FOAM is committed to building spatial protocols, standards and applications that bring geospatial data to blockchains and can empower a consensus-driven map of the world. Very unique and interesting idea to work on radio beacons. The future of proof of location is in FOAM.

FOAM is an intriguing project utilizing low power wide area networks (LPWAN) as location "anchors" to provide the network with reliable location information. This is a block foundry launch and the team is solid with reliable backing. I am excited about this project.
