                                                           BalanceBean payer)
```
    This function alters the payer's balance sheet. This function must be called only after verifying that the payer can afford to execute the transaction. The verification is carried out through canPayFee == true. If the function is called on a payer with an unsustainable balance sheet, it will give rise to a negative balance sheet.
    
    Parameters:
    
    tbox -
    
    payer -
    
    Returns:
    
    the reward due to the node for the execution of the current transaction
