What are parachains?

Parachains are sovereign blockchains running in parallel within the Kusama and Polkadot networks. Conceived by Gavin Wood, co-founder and former CTO of Ethereum, parachains bring the future of the internet to a whole new level, allowing the scalability, interoperability, and security needed to really turn the promise of blockchain into the next generation of the internet, Web 3.0.
