Kusama coin is the native coin of the Kusama blockchain, which is intended to serve as an unaudited and unrefined release of Polkadot. Kusama will serve as a trail version for Polkdadot, and will allow developers to build and deploy a parachain or try out Polkadot’s governance, staking, nomination and validation functionality in a real environment.

The Kava token fuels the Kava.io cross-chain collateralized debt platform. Kava’s multi collateral CDP system allows users to collateralize a variety of assets so that they can increase their exposure to favorable trading conditions in volatile markets. The Kava platform is secured by over 100 validators and uses the Tendermint consensus algorithm.

The Nervos Network is an open-source public blockchain ecosystem that is designed to secure multiple assets. Unlike other smart contract platforms that require users to pay transaction fees to help secure the underlying networks, the Nervos Network hopes to create an incentive system that will enable multiple assets to be secured regardless of their price volatility. It does this by capturing the total network value through its native coin the Nervos CKByte, which entitles holders to storage rights on the Nervos blockchain. The network uses a PoW consensus mechanism.
