Overview
Polkadot is often called a 'Layer 0' because it provides the foundation for other blockchains to build upon. Its goal is to create a 'web of blockchains' that can communicate and share security.
Architecture
- Relay Chain: The heart of the network, responsible for shared security and consensus.
- Parachains: Independent, specialized blockchains that connect to the Relay Chain.
- Bridges: Allow Polkadot to connect to external networks like Bitcoin or Ethereum.
Governance
Polkadot features a sophisticated on-chain governance system where DOT holders have direct control over the protocol's future.
