Cumulus parachain inherent
The ParachainInherentData
is the data that is passed by the collator to the parachain
runtime. The runtime will use this data to execute messages from other parachains/the relay
chain or to read data from the relay chain state. When the parachain is validated by a parachain
validator on the relay chain, this data is checked for correctness. If the data passed by the
collator to the runtime isn’t correct, the parachain candidate is considered invalid.
To create a ParachainInherentData
for a specific relay chain block, there exists the
ParachainInherentDataExt
trait in cumulus-client-parachain-inherent
that helps with this.
Structs§
- This struct provides ability to extend a message queue chain (MQC) and compute a new head.
- The inherent data that is passed by the collator to the parachain runtime.
Constants§
- The identifier for the parachain inherent.
