Polkadot is a Layer-0 protocol designed to connect multiple specialized blockchains—called parachains—into a unified, interoperable ecosystem. Built using the Substrate framework, Polkadot enables developers to create custom, purpose-built blockchains that plug into its central relay chain for shared security and cross-chain communication.
Key features include:
Polkadot is designed to serve as the foundation for a decentralized web, enabling a modular, multi-chain architecture optimized for performance and innovation.
