Polkadot is a next-gen blockchain network designed to facilitate the interchange of multiple blockchains. Whereas other networks work in isolation, Polkadot links various blockchains into one unified network, enabling them to communicate and share information and funds. It does this with a novel architecture that has a central Relay Chain that coordinates parachains. This setup improves scalability, security, and flexibility. It also has OpenGov, a decentralized governance system where token holders vote on upgrades and proposals. DOT is the native token of Polkadot that is employed for staking and governance. Being inspired by the idea of a decentralized and interconnected Web3, Polkadot was built with a vision of a truly decentralized and interconnected network.
