Polkadot (DOT)

Polkadot is a blockchain network which can be described as a ‘blockchain of blockchains’, or multichain and is maintained by former Ethereum CTO Gavin Wood. Launched in 2020, Polkadot is often described as a “next generation” blockchain” and has raised over $200 million from investors. Polkadot consists of two blockchains, the main chain known as a relay chain and a second chain known as parachains. Parachains can feed into the main chain and receive the same security benefits from this. Parachains allow users to build on top of Polkadot in a similar fashion to how users can build onto Ethereum.
