    ) -> Result<(), ConsensusError> { ... }
}

Type that validates an ExecutionPayload.

Required Associated Types

type Block: Block

The block type used by the engine.

type ExecutionData

The execution payload type used by the engine.

Required Methods

fn ensure_well_formed_payload( &self, payload: Self::ExecutionData, ) -> Result<RecoveredBlock<Self::Block>, NewPayloadError>

Ensures that the given payload does not violate any consensus rules that concern the block’s layout.

This function must convert the payload into the executable block and pre-validate its fields.

Implementers should ensure that the checks are done in the order that conforms with the engine-API specification.

Provided Methods

fn validate_block_post_execution_with_hashed_state( &self, _state_updates: &HashedPostState, _block: &RecoveredBlock<Self::Block>, ) -> Result<(), ConsensusError>

Verifies payload post-execution w.r.t. hashed state updates.
