Polkadot (DOT) is a multi-chain blockchain platform created by Gavin Wood, another co-founder of Ethereum. The core concept is interoperability — Polkadot enables different blockchains (called parachains) to communicate and share security under a central relay chain.
Polkadot's architecture consists of a central Relay Chain (the main network that provides security), Parachains (independent blockchains connected to the Relay Chain), Parathreads (pay-as-you-go parachains), and Bridges (connections to external networks like Bitcoin and Ethereum). This design allows specialized blockchains to interoperate seamlessly.
DOT has multiple functions within the ecosystem: governance (DOT holders vote on network upgrades), staking (securing the network earns staking rewards), and bonding (required to connect parachains). Polkadot's OpenGov system, launched in 2023, enables more decentralized and granular governance than any other major blockchain.
