FOAM is developing a blockchain-based location service protocol for embedding physical locations in Ethereum smart contracts. The FOAM network will use radio beacons and will provide incentives for decentralized location services that will be given by network participants. Users will stake tokens to become zone anchors, that will work with radio beacons to return location data to the network. FOAM's Proof of Location protocol will be used to confirm consensus on the location of objects and entities in space and time.

RealTract is developing a smart contract platform based on a Directed Acylic Graph (DAG) protocol. They hope to create a faster and more scalable smart contract platform that can handle more use cases. The RealTract network is currently powered by the Ethereum-based RET token.
