Expand description

Messages received by the Collator Protocol subsystem.

Variants§

§

CollateOn(Id)

Signal to the collator protocol that it should connect to validators with the expectation of collating on the given para. This is only expected to be called once, early on, if at all, and only by the Collation Generation subsystem. As such, it will overwrite the value of the previous signal.

This should be sent before any DistributeCollation message.

§

DistributeCollation

Provide a collation to distribute to validators with an optional result sender.

Fields

§candidate_receipt: CandidateReceipt

The receipt of the candidate.

§parent_head_data_hash: Hash

The hash of the parent head-data. Here to avoid computing the hash of the parent head data twice.

§pov: PoV

Proof of validity.

§parent_head_data: HeadData

This parent head-data is needed for elastic scaling.

§result_sender: Option<Sender<CollationSecondedSignal>>

The result sender should be informed when at least one parachain validator seconded the collation. It is also completely okay to just drop the sender.

§core_index: CoreIndex

The core index where the candidate should be backed.

§

ReportCollator(CollatorId)

Report a collator as having provided an invalid collation. This should lead to disconnect and blacklist of the collator.

§

NetworkBridgeUpdate(NetworkBridgeEvent<CollatorProtocolMessage>)

Get a network bridge update.

§

Invalid(Hash, CandidateReceipt)

We recommended a particular candidate to be seconded, but it was invalid; penalize the collator.

The hash is the relay parent.

§

Seconded(Hash, SignedFullStatement)

The candidate we recommended to be seconded was validated successfully.

The hash is the relay parent.
