}

Type that validates the payloads processed by the engine.

This provides the necessary functions for validating/executing payloads/blocks.

Required Methods

fn validate_payload_attributes_against_header( &self, attr: &Types::PayloadAttributes, header: &N::BlockHeader, ) -> Result<(), InvalidPayloadAttributesError>

Validates the payload attributes with respect to the header.

By default, this enforces that the payload attributes timestamp is greater than the timestamp according to:

7. Client software MUST ensure that payloadAttributes.timestamp is greater than timestamp of a block referenced by forkchoiceState.headBlockHash.

See also: https://github.com/ethereum/execution-apis/blob/main/src/engine/common.md#specification-1

fn ensure_well_formed_payload( &self, payload: Types::ExecutionData, ) -> Result<RecoveredBlock<N::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.

fn validate_payload( &mut self, payload: Types::ExecutionData, ctx: TreeCtx<'_, N>, ) -> ValidationOutcome<N>

Validates a payload received from engine API.

fn validate_block( &mut self, block: RecoveredBlock<N::Block>, ctx: TreeCtx<'_, N>, ) -> ValidationOutcome<N>

Validates a block downloaded from the network.
