What Is KSM?

Kusama is a public blockchain network that is running the exact same codebase as Polkadot. It is aimed to be a canary build for the Polkadot network which is an experimental and development environment for new features that will eventually be deployed to Polkadot. Because of the experimental nature of Kusama, the developmental speed is much faster and it has seen significant traction since launched in 2019.
