XinFin is a blockchain technology company that has developed the XDC protocol. XinFin's hybrid blockchain enables peer-to-peer contracts on a regulated payment infrastructure. Their goal is to create an open source marketplace platform that will reduce inequalities in global finance.
The XDC blockchain is built upon Quorum, a permissioned blockchain developed by J.P. Morgan. Quorum was developed as a layer upon the Go implementation of the
Ethereum protocol. XDC's consensus mechanism allows for new blocks be created in a two-step process. In the first step, the transactions to be included in the new block are voted upon by all participating nodes. In the second step, one node is selected as the leader or block maker randomly. The block maker node then creates the new block.
XInFin is powered by the XDCE token.

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.

Ignis is a blockchain platform that is being developed by Jeluirda; the company behind Ardor and Nxt. Ignis is a child chain of the Nxt blockchain. Jelurida is developing blockchain platforms that will enable users to develop decentralized applications, and will be based on a parent and child chain architecture.
Ignis allows users to create child chains with specific features and to create tokens that meet their needs. This project is closely related to Ardor and Nxt.
