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.

Polymath is a blockchain-based protocol that makes it easier to raise capital and create security tokens. The Polymath ST-20 standard embeds regulatory requirements into the tokens themselves, restricting trading to verified participants only. The protocol simplifies the complex technical challenges of creating a security token and aims to bring the multi-trillion dollar financial securities market to the blockchain.

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.
