Kusama is an experimental version of Polkadot. It enables users, teams and developers to experiment with Polkadot’s governance, staking, nomination and validation functionality or to build and deploy a parachain in a real environment. In addition to the staking rewards earned on Kusama, 1% of DOTs (native to Polkadot) will be distributed to Kusama participants, although the reward distribution mechanism has not yet been determined.
