Question 2

Relay Chain

Answer 2

The central chain that provides security and coordination

Question 3

Parachains

Answer 3

Independent blockchains connected to the Relay Chain

Question 4

Heterogeneous Sharding

Answer 4

A blockchain design where multiple independent blockchains (shards — called parachains in Polkadot) run in parallel, each with its own rules, token, and consensus — yet they’re often connected to a central chain (like Polkadot’s Relay Chain) for shared security and cross-chain communication.
