Polkadot is a next-generation blockchain platform that enables interoperability and scalability across different blockchains within a unified network. Launched in 2020 by the Web3 Foundation and co-founded by Dr. Gavin Wood, Polkadot addresses blockchain isolation by allowing independent blockchains, called parachains, to communicate and share data securely. This architecture, featuring a central "Relay Chain" for security and coordination, allows parallel processing of transactions, significantly boosting throughput and efficiency.
The native token, DOT, is essential for governance, staking, and connecting parachains to the network. Polkadot's design encourages innovation by making it easier for developers to build custom blockchains with shared security and cross-chain communication. This vision for a connected, decentralized internet has positioned Polkadot as a leading force in the blockchain space, supporting projects across finance, gaming, and other sectors.
