Kusama is a network built as a risk-taking, fast-moving 'canary in the coal mine' for its cousin Polkadot. As it is built on top of the same infrastructure, Kusama often acts as a final testing ground for new features before they are launched on Polkadot. Unlike true TestNets, however, the Kusama KSM native token does have economic value. This incentive encourages paricipants to maintain this robust and performant structure for the benefit of the community.
