FOAM is a decentralised platform built on the Ethereum blockchain aimed at creating a secure and verifiable system for location-based services. It focuses on enhancing trust and reducing vulnerabilities in geospatial data management by introducing a consensus-driven approach to mapping the world.
FOAM operates using a "Proof of Location" consensus mechanism, which is designed to provide a trustworthy method of verifying and managing location data. This involves a geospatial consensus protocol and the use of crypto-spatial coordinates to ensure accurate data verification. The platform also employs smart contracts to manage staking and safety deposits, and incentivises participation through spatially weighted mining rewards.
FOAM has a broad range of potential applications, including:
FOAM was established with the publication of its whitepaper on May 1, 2018, outlining its vision for a decentralised geospatial data protocol. The project has developed over time to integrate various spatial protocols and standards that enhance geospatial data management on blockchains, solidifying its presence within the realm of crypto-based geospatial services.
