Applied global changes: Polkadot->Pezkuwi, Parachain->TeyrChain, pallet->pezpallet, frame->pezframe. Updated authors in Cargo.toml to include Kurdistan Tech Institute and pezkuwichain team. Used Cargo aliases to maintain SDK compatibility while using rebranded names in source code.

Branch/Release: `release-polkadot-v1.10.0`
|
||
|
||
== Purpose
|
||
|
||
This pezpallet integrates parachain’s own block production mechanism (for example AuRa) into Cumulus parachain system. It allows:
|
||
|
||
- to manage the unincluded blocks from the current slot
|
||
- to validate produced block against the relay chain
|
||
|
||
== Configuration and Integration link:https://github.com/paritytech/polkadot-sdk/tree/release-polkadot-v1.10.0/cumulus/pezpallets/aura-ext[{github-icon},role=heading-link]
|
||
|
||
There is no special config for this integration and it has no dispatchables, but you need to integrate it with other `parachain-system` crate:
|
||
|
||
=== Integrate `BlockExecutor`
|
||
|
||
When you invoke the `register_validate_block` macro, you should provide `cumulus_pezpallet_aura_ext::BlockExecutor` to it to allow `aura-ext` to validate the blocks produced by `aura`
|
||
|
||
[source, rust]
|
||
----
|
||
cumulus_pezpallet_parachain_system::register_validate_block! {
|
||
Runtime = Runtime,
|
||
BlockExecutor = cumulus_pezpallet_aura_ext::BlockExecutor::<Runtime, Executive>,
|
||
}
|
||
----
|
||
|
||
=== Integrate `ConsensusHook`
|
||
|
||
Also you might want to manage the consensus externally and control the segment that is not yet included (its capacity, speed and etc.) `aura-ext` provides the `FixedVelocityConsensusHook` that allows to check if we are still in the limits for the slot.

impl cumulus_pezpallet_parachain_system::Config for Runtime {
|
||
...
|
||
type ConsensusHook = cumulus_pezpallet_aura_ext::FixedVelocityConsensusHook<
