The XY Oracle Network is a blockchan-based location verification service. It is designed to be compatible with many devices and across different smart contract protocols. XYO uses innovative cryptographic techniques to combine real-world data with a blockchain-based system that can be used by DApps. The XYO Network was developed by a San Diego based company called XY, that makes GPS and Bluetooth devices. The company is building the network's infrastructure that will consist of location-verifying beacons that will enable smart contracts to incorporate location data. The network is powered by the Ethereum-based XYO token.

FLO is a Proof-of-Work blockchain with a metadata layer called floData. It enables users to easily record notes to its blocks, and can be used to create DApps. One of FLO's central features is the Open Index Protocol, which standardizes cryptographic ownership on open networks. The founders of FLO are also working on Alexandria; an open-source standard for users to publish and distribute original content. FLO's source code is based on that of Bitcoin and Litecoin. It is designed to enable fast transactions times.
