Kusama is an early, unaudited, and unrefined release of Polkadot. Kusama aims to serve as a proving ground, allowing teams and developers to build and deploy a parachain or try out Polkadot’s governance, staking, nomination, and validation functionality in a real environment. Kusama is a scalable network of specialized blockchains built using Substrate and nearly the same codebase as Polkadot. The network is an experimental development environment for teams who want to move fast and innovate on Kusama, or prepare for deployment on Polkadot. Kusama was founded in 2019 by Gavin Wood, founder of Polkadot and co-founder and former CTO of Ethereum.
