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 Matic Network is a sidechain based scaling solution for public blockchains. Matic aims to allow developers to better scale their Ethereum DApps by using a version of Plasma, along with side chains that use a PoS consensus mechanism. Matic plans on supporting other blockchains as well in order to facilitate interoperability.

ARK, which is a fork of Lisk, is developing an interconnected blockchain ecosystem that will make it easier for users to develop their own blockchains. Ark emphasizes interoperability and usability. Their moto is “Point.Click.Blockchain” and their goal is to allow for easy deployment of DApps. Ark's "push button blockchains" can be easily created with minimal programming knowledge. Ark also hopes to encourage adoption by developers by accommodating 18 different programming languages.
Ark has a delegated Proof-of-Stake (dPoS) consensus mechanism. Their governance model allows users to vote for delegates that secure the network. The top 51 delegates voluntarily share there tokens with their voters.
Ark contract execution service (ACES) connects ARK with other blockchains and will enable exchanges of value between them.
