cumulus-pallet-parachain-system is a base pallet for Cumulus-based parachains.
This pallet handles low-level details of being a parachain. Its responsibilities include:
- ingestion of the parachain validation data;

- coordinating upgrades with the Relay Chain; and
- communication of parachain outputs, such as sent messages, signaling an upgrade, etc.
Users must ensure that they register this pallet as an inherent provider.
