```python ```python
def get_base_reward(state: BeaconState, index: ValidatorIndex) -> Gwei: def get_base_reward(state: BeaconState, index: ValidatorIndex) -> Gwei:
if get_previous_total_balance(state) == 0:
return 0
adjusted_quotient = integer_squareroot(get_previous_total_balance(state)) // BASE_REWARD_QUOTIENT adjusted_quotient = integer_squareroot(get_previous_total_balance(state)) // BASE_REWARD_QUOTIENT
return get_effective_balance(state, index) // adjusted_quotient // 5 return get_effective_balance(state, index) // adjusted_quotient // 5
``` ```
