}

Hooks related to the Sequencer functionality. In essence, the sequencer locks a bond at the beginning of the StateTransitionFunction::apply_blob, and is rewarded once a blob of transactions is processed.

type Context: Context

type BlobResult

Required Methods

fn begin_blob_hook( &self, sequencer: &[u8], raw_blob: &[u8], working_set: &mut WorkingSet<<Self::Context as Spec>::Storage> ) -> Result<()>

Runs at the beginning of apply_blob, locks the sequencer bond.

fn end_blob_hook( &self, result: Self::BlobResult, working_set: &mut WorkingSet<<Self::Context as Spec>::Storage> ) -> Result<()>

Executes at the end of apply_blob and rewards the sequencer. This method is not invoked if the sequencer has been slashed.
