Architecture¶
Explore Polkadot's architecture, including the relay chain, parachains, and system chains, and discover the role each component plays in the broader ecosystem.
A Brief Look at Polkadot’s Chain Ecosystem¶
The following provides a brief overview of the role of each chain:
-
Polkadot relay chain: The central hub and main chain responsible for the overall security, consensus, and interoperability between all connected chains.
-
System chains: Specialized chains that provide essential services to the ecosystem, like the Asset Hub, Bridge Hub, and Coretime chain.
-
Parachains: Individual, specialized blockchains that run parallel to the relay chain and are connected to it.
