Vision of Polkadot

Polkadot was co-founded by Gevin Wood (Dr. Gavin James Wood) who also co-founded and former CTO of Ethereum network. 

Nowaday, there are thousands of blockchain created with different purposes, but they are not truly connected. That is where Polkadot aims to solve it by connecting these blockchain together using Relay Chain technology. They can see that in the future, there will not be solely dominating blockchain, instead these blockchains will co-exist and be connected like the internet of blockchain.
