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.

The Interplanetary File System (IPFS) is a decentralized network protocol for sharing hypermedia in a distributed file system. IPFS can be used to link blockchain transactions This effectively timestamps and secures the content, without having to put the data on the chain itself. Filecoin, an IPFS-based decentralized storage cloud, is closely related with the IPFS protocol, and provides the incentive system.

BOScoin is a South Korean company that is developing a self-evolving cryptocurrency platform for trust contracts. It uses an embedded decision-making system called Congress Network and has a Proof-of-Stake (PoS) consensus mechanism. BOScoin is working to construct an algorithm for smart contracts that will ensure binary responses. BOScoin tries to solve this problem of undecidability of smart contracts by using a domain-specific language understandable by the average user. It also tries to mathematically demonstrate the decidability of its smart contracts’ implementation. To do this, they've introduced the concept of Trust Contracts; which are securely executable contracts based on a technology called Owlchain.
