peaq is built using Substrate and will connect to the Polkadot Relay Chain as a parachain. A parachain is a blockchain that is connected to a larger relay chain. The goal is for the relay chain to provide a high level of security, with its large validator set and high value at stake, to all of its connected parachains. There are benefits of being an own parachain such as outsourcing chain security to achieve a higher level of security at a better cost - allowing to focus more on core features. Another important benefit would be to use the relay chain to bridge to other chains in the Polkadot ecosystem.
