The FOAM Proof of Location protocol empowers a network of radio beacons that can offer secure location services independent of external centralized sources such as GPS through time synchronization.
- An open standard for location in Ethereum smart contracts.
- Consensus on whether an event or agent is verifiably at a certain point in time and space.
- A general purpose visual blockchain explorer that enables users to understand, engage and act with spatial data.
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. Zones can include time stamped messages from customers in a competitive market for a transaction fee.
