Polkadot, introduced in 2020, is an innovative blockchain designed as a central hub for diverse blockchains. Known as a 'layer-0' blockchain, it fosters seamless interaction among various cryptocurrencies. Dr. Gavin Wood, its founder, closely aligns Polkadot with the vision of a decentralized web (web3). The native token, DOT, plays a pivotal role in staking, governance, and bonding—forming connections between DOT tokens and new chains on the network.
