## Introduction
This document represents the changes to be made in the code of an "honest validator".
## Prerequisites
This document is an extension of the [Deneb -- Honest Validator](../deneb/validator.md) guide.
All behaviors and definitions defined in this document, and documents it extends, carry over unless explicitly noted or overridden.
All terminology, constants, functions, and protocol mechanics defined in the updated [Beacon Chain doc of EIP-7251](./beacon-chain.md) are requisite for this document and used throughout.
Please see related Beacon Chain doc before continuing and use them as a reference throughout.
## Beacon chain responsibilities
All validator responsibilities remain unchanged other than those noted below.
### Block and sidecar proposal
#### Constructing the `BeaconBlockBody`
##### ExecutionPayload
`prepare_execution_payload` is updated from the Deneb specs.
*Note*: In this section, `state` is the state of the slot for the block proposal _without_ the block yet applied.
That is, `state` is the `previous_state` processed through any empty slots up to the assigned slot using `process_slots(previous_state, slot)`.
*Note*: The only change to `prepare_execution_payload` is the new definition of `get_expected_withdrawals`.
```python
def prepare_execution_payload(state: BeaconState,
safe_block_hash: Hash32,
finalized_block_hash: Hash32,
suggested_fee_recipient: ExecutionAddress,
execution_engine: ExecutionEngine) -> Optional[PayloadId]:
# Verify consistency of the parent hash with respect to the previous execution payload header
parent_hash = state.latest_execution_payload_header.block_hash
# Set the forkchoice head and initiate the payload build process
withdrawals, _ = get_expected_withdrawals(state) # [Modified in EIP-7251]
payload_attributes = PayloadAttributes(
timestamp=compute_timestamp_at_slot(state, state.slot),
prev_randao=get_randao_mix(state, get_current_epoch(state)),
suggested_fee_recipient=suggested_fee_recipient,
withdrawals=withdrawals,
parent_beacon_block_root=hash_tree_root(state.latest_block_header),
)
return execution_engine.notify_forkchoice_updated(
head_block_hash=parent_hash,
safe_block_hash=safe_block_hash,
finalized_block_hash=finalized_block_hash,
payload_attributes=payload_attributes,
)
```
