The relay chain and parachains
Polkadot’s architecture revolves around the Relay Chain. Around it orbit various parachains individual blockchains with specific uses. These parachains can specialise in anything from decentralized finance (DeFi) to gaming or identity management.
Because Polkadot doesn’t have apps on it, it’s called a zero layer, because it is a foundation layer. But the parachains around it do have dApps (apps made on a blockchain rather than the internet). Here are some really to look into.
Imagine Polkadot as a bustling city with different districts, each serving a unique purpose. The Relay Chain ensures seamless communication between these districts.
Substrate
Developers can create their own parachains using the Substrate framework. It’s like building with Lego blocks — assemble your unique blockchain, connect it to Polkadot, and benefit from the network’s security and interoperability.
This flexibility encourages innovation and rapid development.
