Execution payload validator.

Implementations§

Source§

impl<ChainSpec> ExecutionPayloadValidator<ChainSpec>

Source

pub const fn new(chain_spec: Arc<ChainSpec>) -> Self

Create a new validator.

Source

pub const fn chain_spec(&self) -> &Arc<ChainSpec>

Returns the chain spec used by the validator.

Source§

impl<ChainSpec: EthereumHardforks> ExecutionPayloadValidator<ChainSpec>

Source

pub fn ensure_well_formed_payload<T: SignedTransaction>( &self, payload: ExecutionPayload, sidecar: ExecutionPayloadSidecar, ) -> Result<SealedBlock<Header, BlockBody<T>>, PayloadError>

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

  • missing or invalid base fee
  • invalid extra data
  • invalid transactions
  • incorrect hash
  • the versioned hashes passed with the payload do not exactly match transaction versioned hashes
  • the block does not contain blob transactions if it is pre-cancun

The checks are done in the order that conforms with the engine-API specification.

This is intended to be invoked after receiving the payload from the CLI. The additional [MaybeCancunPayloadFields] are not part of the payload, but are additional fields in the engine_newPayloadV3 RPC call, See also https://github.com/ethereum/execution-apis/blob/fe8e13c288c592ec154ce25c534e26cb7ce0530d/src/engine/cancun.md#engine_newpayloadv3

If the cancun fields are provided this also validates that the versioned hashes in the block match the versioned hashes passed in the CancunPayloadFields, if the cancun payload fields are provided. If the payload fields are not provided, but versioned hashes exist in the block, this is considered an error: [PayloadError::InvalidVersionedHashes].

This validates versioned hashes according to the Engine API Cancun spec: https://github.com/ethereum/execution-apis/blob/fe8e13c288c592ec154ce25c534e26cb7ce0530d/src/engine/cancun.md#specification
