Polkadot is a platform designed to facilitate interaction between blockchains and enable asset transfers between chains. It was founded by Dr. Gavin Wood, a former developer of Ethereum, in 2016. The native token of Polkadot is DOT. Additionally, Polkadot uses a customized programming language called Substrate for the development of smart contracts. In short, Polkadot acts as a bridge between chains and allows for different chains to interact with each other.
