Cumulus 云像点状浮在空中，跟这个项目很相像（因为以 Cumulus 云为原型故得名——待项目发展得更酷，我们可能会对它重新命名，敬请期待。）
Cumulus is an extension to Substrate that makes it easy to make any Substrate built runtime into a Polkadot compatible parachain.
Cumulus Consensus is a consensus engine for Substrate that follows a Polkadot Relay Chain. This will run a Polkadot node internally, and dictate to the client and synchronization algorithms which chain to follow, finalize, and treat as best.
A wrapper around Substrate runtimes to allow them to be validated by Polkadot validators and provide witness generating routines. It adds a
validate_block API to the Substrate external interface, which will be called by validators.
将它集成到 substrate runtime 就像导入 crate 包并将这一行宏添加到代码中一样简单。
计划为平行链的 Polkadot 收集人。
