Cumulus‐based NPOS Parachain
The documentation is mainly about how to connect our existing NPOS parachain to the relaychain as a parachain.
A set of tools for writing Substrate-based Polkadot parachains. Refer to the included overview for architectural details, and the Connect to a relay chain how-to guide for a guided walk-through of using these tools.
It's easy to write blockchains using Substrate, and the overhead of writing parachains' distribution, p2p, database, and synchronization layers should be just as low. This project aims to make it easy to write parachains for Polkadot by leveraging the power of Substrate.
Cumulus clouds are shaped sort of like dots; together they form a system that is intricate, beautiful and functional.

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; = ingestion and dispatch of incoming downward and lateral messages;
- 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.
