Video: FOAM — How Proof of Location works
This demo video explains in detail and visualizes how the FOAM Proof of Location protocol works.
From the initial Zone formation to how a Presence Claim is added to the Ethereum blockchain, we hope this video helps explain how the Dynamic Proof of Location protocol functions.
FOAM is building a decentralized Proof of Location protocol that offers a higher level of security and network strength than conventional location based services.
To become a location service provider, a radio beacon stakes a safety deposit of FOAM tokens to participate in the network as a Zone Anchor. It searches for three other beacons nearby. Once four Zone Anchors are connected, they ping messages back and forth to synchronize their clocks. After reaching consensus on the time, a Zone is established and the Zone Anchors are rewarded in FOAM tokens.
A location customer enters the Zone and requests a Presence Claim. Then it transfers the Zone Authorities a fee. Each Zone Authority detects its distance to the location customer by measuring the time it takes to receive a message. Once measured, the Zone Authorities store the information on their local blockchain to reach consensus on what happened.
The Presence Claim is sent to Verifiers. They receive it and check the data against the data reported in other zones. This is then printed in the Ethereum blockchain and made public. The Location Customer receives its verified location claim through a decentralized application.
Proof of Location has uses across an array of verticals: mobility & transportation, location based gaming, and supply chains.

Disclaimer: Please note that Dynamic Proof of Location will not be available at the time of sale, and is previewed for information purposes only. The availability of these features in the future will depend on the circumstances described in the Dynamic Proof of Location section of the FOAM product White Paper.
Please note that the verticals and use cases referred to in this post remain potential use cases only, are provided for information and discussion only, and would not reflect the utility or functionality of the FOAM protocol at launch — the success of any use cases will depend on how users and community participants expand and build out the FOAM network, as well as the development of the proof of location protocol (including in particular the establishment of zones, which are not envisaged at the initial launch), before any potential use cases might come to fruition.
