## Introduction
|
||||
|
||||
This is the beacon chain specification of the execution layer triggerable exits feature.
|
||||
|
||||
This mechanism relies on the changes proposed by [EIP-7002](http://eips.ethereum.org/EIPS/eip-7002).
|
||||
|
||||
*Note:* This specification is built upon [Capella](../../capella/beacon-chain.md) and is under active development.
|
||||
|
||||
## Preset
|
||||
|
||||
### Max operations per block
|
||||
|
||||
| Name | Value |
|
||||
| - | - |
|
||||
| `MAX_EXECUTION_LAYER_EXITS` | `2**4` (= 16) |

### Block processing
|
||||
|
||||
#### Execution payload
|
||||
|
||||
##### Modified `process_execution_payload`
|
||||
|
||||
```python
|
||||
def process_execution_payload(state: BeaconState, body: BeaconBlockBody, execution_engine: ExecutionEngine) -> None:
|
||||
payload = body.execution_payload
|
||||
# Verify consistency of the parent hash with respect to the previous execution payload header
|
||||
assert payload.parent_hash == state.latest_execution_payload_header.block_hash
|
||||
# Verify prev_randao
|
||||
assert payload.prev_randao == get_randao_mix(state, get_current_epoch(state))
|
||||
# Verify timestamp
|
||||
assert payload.timestamp == compute_timestamp_at_slot(state, state.slot)
|
||||
# Verify the execution payload is valid
|
||||
assert execution_engine.verify_and_notify_new_payload(NewPayloadRequest(execution_payload=payload))
|
||||
# Cache execution payload header
|
||||
state.latest_execution_payload_header = ExecutionPayloadHeader(
|
||||
parent_hash=payload.parent_hash,
|
||||
fee_recipient=payload.fee_recipient,
|
||||

|
||||

|
||||
)
|
||||
```
|
||||
|
||||
#### Operations
|
||||
|
||||
##### Modified `process_operations`
|
||||
|
||||
*Note*: The function `process_operations` is modified to process `ExecutionLayerExit` operations included in the block.
|
||||
|
||||
```python
|
||||
def process_operations(state: BeaconState, body: BeaconBlockBody) -> None:
|
||||
# Verify that outstanding deposits are processed up to the maximum number of deposits
|
||||
assert len(body.deposits) == min(MAX_DEPOSITS, state.eth1_data.deposit_count - state.eth1_deposit_index)
|
||||
|
||||
def for_ops(operations: Sequence[Any], fn: Callable[[BeaconState, Any], None]) -> None:
|
||||
for operation in operations:
|
||||
fn(state, operation)
|
||||
|
||||
for_ops(body.proposer_slashings, process_proposer_slashing)
|
||||
for_ops(body.attester_slashings, process_attester_slashing)
|
||||
for_ops(body.attestations, process_attestation)
|
||||
for_ops(body.deposits, process_deposit)
|
||||
for_ops(body.voluntary_exits, process_voluntary_exit)
|
||||
for_ops(body.execution_payload.exits, process_execution_layer_exit) # [New in EIP7002]
|
||||
for_ops(body.bls_to_execution_changes, process_bls_to_execution_change)
|
||||
```
|
||||
|
||||
##### New `process_execution_layer_exit`
|
||||
|
||||
```python
|
||||
def process_execution_layer_exit(state: BeaconState, execution_layer_exit: ExecutionLayerExit) -> None:
|
||||
validator_pubkeys = [v.pubkey for v in state.validators]
|
||||
validator_index = ValidatorIndex(validator_pubkeys.index(execution_layer_exit.validator_pubkey))
|
||||
validator = state.validators[validator_index]
|
||||
|
||||
# Verify withdrawal credentials
|
||||
is_execution_address = validator.withdrawal_credentials[:1] == ETH1_ADDRESS_WITHDRAWAL_PREFIX
|
||||

## Testing
|
||||
|
||||
*Note*: The function `initialize_beacon_state_from_eth1` is modified for pure EIP-7002 testing only.
|
||||
Modifications include:
|
||||
1. Use `EIP7002_FORK_VERSION` as the previous and current fork version.
|
||||
2. Utilize the EIP-7002 `BeaconBlockBody` when constructing the initial `latest_block_header`.
|
||||
|
||||
```python
|
||||
def initialize_beacon_state_from_eth1(eth1_block_hash: Hash32,
|
||||
eth1_timestamp: uint64,
|
||||
deposits: Sequence[Deposit],
|

|
||||
randao_mixes=[eth1_block_hash] * EPOCHS_PER_HISTORICAL_VECTOR, # Seed RANDAO with Eth1 entropy
|

|
||||
|
||||

|
||||

|

|

if validator.effective_balance == MAX_EFFECTIVE_BALANCE:
|

validator.activation_eligibility_epoch = GENESIS_EPOCH
|

state.current_sync_committee = get_next_sync_committee(state)

## Introduction
|
||||
|
||||
This document describes the process of EIP-7002 upgrade.
|
||||
|
||||
## Configuration
|
||||
|
||||
Warning: this configuration is not definitive.
|
||||
|
||||
| Name | Value |
|
||||
| - | - |
|
||||
| `EIP7002_FORK_VERSION` | `Version('0x05000000')` |
|
||||
| `EIP7002_FORK_EPOCH` | `Epoch(18446744073709551615)` **TBD** |
|
||||
|
||||
## Helper functions
|
||||
|
||||
### Misc
|
||||
|
||||
#### Modified `compute_fork_version`
|
||||
|
||||
```python
|
||||
def compute_fork_version(epoch: Epoch) -> Version:
|
||||
"""
|
||||
Return the fork version at the given ``epoch``.
|
||||
"""
|
||||
if epoch >= EIP7002_FORK_EPOCH:
|
||||
return EIP7002_FORK_VERSION
|
||||
if epoch >= CAPELLA_FORK_EPOCH:
|
||||
return CAPELLA_FORK_VERSION
|
||||
if epoch >= BELLATRIX_FORK_EPOCH:
|
||||
return BELLATRIX_FORK_VERSION
|
||||
if epoch >= ALTAIR_FORK_EPOCH:
|
||||
return ALTAIR_FORK_VERSION
|
||||
return GENESIS_FORK_VERSION
|
||||
```
|
||||
|
||||
## Fork to EIP-7002
|
||||
|
||||
### Fork trigger
|
||||
|
||||
TBD. This fork is defined for testing purposes, the EIP may be combined with other consensus-layer upgrade.
|
||||
For now, we assume the condition will be triggered at epoch `EIP7002_FORK_EPOCH`.
|
||||
|
||||
Note that for the pure EIP-7002 networks, we don't apply `upgrade_to_eip7002` since it starts with EIP-7002 version logic.
|
||||
|
||||
### Upgrading the state
|
||||
|
||||
If `state.slot % SLOTS_PER_EPOCH == 0` and `compute_epoch_at_slot(state.slot) == EIP7002_FORK_EPOCH`,
|
||||
an irregular state change is made to upgrade to EIP-7002.
|
||||
|
||||
```python
|
||||
def upgrade_to_eip7002(pre: capella.BeaconState) -> BeaconState:
|
