Explore Polkadot, a scalable, interoperable blockchain platform powering a network of parachains and enabling next-generation decentralized applications.
Polkadot is a layer-0 protocol that connects multiple specialized blockchains (parachains) into a unified network, offering shared security and cross-chain communication. Built with Substrate and using a nominated proof-of-stake (NPoS) system, it enables seamless scalability and flexible governance. Ideal for deploying production-ready Web3 applications across interoperable chains.
