process_withdrawalsmodifiedget_expected_withdrawalsmodifiedis_builder_payment_withdrawableaddedHow this works
gloas introduces the new
BeaconState.builder_pending_withdrawals, which are pending payments from the in-protocol builder to the proposer that have a withdrawable epoch scheduledprocess_withdrawalsruns during block processing, the same as today. However, in the nestedget_expected_withdrawals, we now sweep through the list ofbuilder_pending_withdrawalsand convert the ones that have hit their withdrawable epoch toWithdrawalsThen, back in
process_withdrawals, we will sweep these withdrawals and decrement the balance of the builder on the CL. The payment to the fee recipient in the EL is made later via inclusion ofWithdrawalsin the envelope'sExecutionPayload.@ethDreamer
