Polkadot is a multi-chain interoperability platform founded by Dr. Gavin Wood, co-founder of Ethereum. Designed for decentralized web, it connects multiple blockchains, allowing them to communicate and transfer value. Central to Polkadot is the Relay Chain, with Parachains running parallel. Using its native DOT token for governance, staking, and bonding, Polkadot emphasizes decentralized governance and shared security, setting a new standard in blockchain interconnectivity.
