In case a successful network divides by running an enormous amount of cancer nodes, the attacker can double the coins in a manner similar to the methods discussed in the attacks with computing power with less effort. The computational difficulty behind it is discussed in the previous paragraph: Therefore, an attacker wanting to flood the network with cancer nodes should have control over several machines with IP addresses in a large amount of different network ranges. For companies, the absence of an intermediary - intrinsic to the blockchain has several advantages: The old behavior of using the verbose named argument and a boolean value is still maintained for compatibility.
