FOAM (blockchain)

Foam is a blockchain software development company building an open protocol for decentralized geospatial data markets.

Foam is a blockchain software development company building an open protocol for decentralized geospatial data markets built on top of Ethereum. The company is headquartered in Brooklyn, New York City, New York and was founded in 2015 by Ryan John King, Kristoffer Josefsson, and Katya Zavyalova.

The FOAM Proof of Location Protocol allows for autonomous geospatial services through the secure coordination of radio beacons (called Zone Anchors) that verify that an event or user is at a certain time and place. Zone Anchors are FOAMs distributed network of radio beacons with radio transceivers which communicate with each other using a Byzantine Fault tolerant clock synchronization protocol to create accurate and synchronized clocks. Zone Anchors are incentivized through the use of the FOAM cryptocurrency token. When enough Zone Anchors are communicating with each other they create a Zone that maintains a quorum on time and space, and can begin to offer location services that are enforced through smart contract safety deposits. Validators perform triangulations and fraud proofs to verify locations within Zones in exchange for transaction fees.
