Anyone can add places to the FOAM Map and share their knowledge of the world. Cartographers challenge when they find something that seems false or incorrect, starting a process in which the community votes to decide if a location should be included or removed. Cartographers use FOAM tokens to sort places and ensure location data is correct and up to date. Since the tokens have value, spamming has a cost and participants share the value they create. Tokens enable people to agree on which locations should be included in the FOAM Map without the need for a central authority. Currently, FOAM uses Ethereum as its base blockchain. But FOAM could be connected to any other blockchain. As far as the radio beacons are concerned, FOAM’s location protocol is hardware agnostic. In other words, it works with different types of hardware.
