#### Execution payload processing
##### `execution_state_transition`
##### `validate_execution_payload`
Let `execution_state_transition(execution_state_root: Bytes32, execution_payload: ExecutionPayload) -> None` be the transition function of Ethereum execution state.
Let `validate_execution_payload(execution_payload: ExecutionPayload) -> boolean` be the function checking whether given `ExecutionPayload` is valid or not.
The body of the function is implementation dependent.
*Note*: `execution_state_transition` must throw `AssertionError` if either the transition itself or one of the pre or post conditions has failed.
