What is Polkadot?

Polkadot is an advanced sharded, multichain network founded by Dr. Gavin Wood, the co-founder and former chief technology officer of Ethereum and creator of the Solidity programming language. Polkadot is built using Substrate, a blockchain-building framework that makes it easy to create a blockchain optimized for any use case.
