In this episode of Web3 On Fire, Ryan King of Foamspace discusses the background and evolution of the Foam project. Foam started as a geospatial protocol on Ethereum layer one, allowing users to add businesses or locations on-chain. However, the focus shifted to hardware and the development of a proof-of-location system. The hardware consists of zone anchor radios that create a terrestrial GPS network, enabling users to make fraud-proof claims about their location. Foam is exploring various use cases, including delivery verification, NFT minting, and supply chain management. The project is actively seeking collaborations and partnerships in the physical events, games, and IoT sectors.
