DOT

Polkadot is a decentralized, nominated proof‑of‑stake blockchain that serves as a multi‑chain network linking independent blockchains, called parachains, to a central Relay Chain for shared security and consensus. Its core purpose is to enable interoperability, allowing assets and data to move across heterogeneous chains without relying on centralized bridges, and to support scalable decentralized applications ranging from DeFi and smart‑contract platforms to identity and gaming solutions. DOT, the native token, is used for staking, governance, and bonding to secure parachain slots, giving token holders influence over protocol upgrades and parameter changes. By providing a modular architecture and cross‑consensus messaging, Polkadot positions itself as a foundational layer for a more connected Web3 ecosystem.
