Polkadot (DOT) is an open-source project supported by the Web3 Foundation. In June of 2022, it unveiled the beta version of a dashboard that simplifies staking (holding and earning interest on) of DOT. It was founded by Gavin Wood, an Ethereum co-founder, in 2020 as a way to "maybe create the next version of Ethereum," Wood said in a 2021 Protocol interview.
