Polkadot - The Backstory

Polkadot is a framework for scaling out the Ethereum protocol. It was created by Vlad Zamostov and Merit Kotovich of Parity, an open-source software company. Polkadot lets you create chains that can be used in different ways without having to use all shards of Ether. The project has been working on since late 2014 but only just finished its first version this year.
