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.

NIX is developing a cross-chain protocol with an emphasis on privacy. Their platform will be powered by the NIX coin, and will allow users to exchange supported coins with atomic swaps. Nix hopes to eliminate the need for centralized exchanges with their DEX manager. The platform is based on the Ghost Protocol, which uses elements of Zercoin, and integrates the Tor network to provide enhanced security and privacy for users. NIX allows developers create and attach their own networks to the NIX network as sidechains. The cross-chain platform has a Proof-of-Work consensus mechanism.
