Polkadot is the leading layer-0 network – that is, a blockchain whose primary purpose is to facilitate transactions between different blockchains.
Polkadot does this by allowing the creation of secure “parachains” that allow you to conduct transactions between blockchains (i.e. Ethereum and Solana). Users use DOT, the native token of Polkadot, to reserve private space on these parachains. When the transactions are completed, the parachain automatically finalises them on their native blockchains.
DOT is also used as a governance token, giving users the ability to vote on changes to the protocol and is distributed to those who stake their tokens to secure the network.
