FOAM Inc | 981 followers on LinkedIn. The Consensus Driven Map of the World At FOAM, we are committed to building spatial protocols, standards and applications that bring geospatial data to blockchains and can empower a consensus-driven map of the world. FOAM has three main components: 1) Crypto-Spatial Coordinate - An open-source standard for embedding physical location in Ethereum smart contracts. 2) The Spatial Index & Visualizer (SIV) - A visual blockchain explorer for creating, viewing, and interacting with Crypto-Spatial Coordinates on a web map. The SIV can serve as the front-end for decentralized applications and will facilitate FOAM's token curated registries for geographic points of interest. 3) Proof of Location - A protocol for decentralized networks to come to consensus on the location of objects and entities in space and time.
