FOAM is an open protocol for decentralized, geospatial information markets. The protocol is designed to empower customers to construct a consensus-driven map of the world that may be trusted for each software. As know-how evolves and adjustments, maps want to alter too. FOAM secures bodily house on the blockchain, harnessing the ability of Ethereum with a cryptographic software program utility token used to offer computational work and verification to the community. The part components of the FOAM protocol are designed to offer spatial protocols, requirements and functions that convey geospatial information to blockchains and empower a consensus-driven map of the world. Token mechanisms and cryptoeconomics underpin the weather of FOAM and empower the distributed customers to coordinate and work together in a decentralized and permissionless vogue.
