Question

What is a relay chain in blockchain?

Answer 1

In blockchain jargon, a relay chain is a fundamental component of a multi-chain architecture, such as the one used in Polkadot. The relay chain serves as the main chain that coordinates communication and security between different parachains (side chains) within the network. It plays a crucial role in ensuring interoperability and scalability in a blockchain ecosystem.

Answer 2

A relay chain in blockchain refers to the main chain in a blockchain network, such as the chain in the Polkadot network. It is responsible for the network's security, consensus, and finality, as well as coordinating communication between different parachains (parallel blockchains) within the ecosystem. The relay chain ensures interoperability and scalability across the entire blockchain network.
