... Keep in mind that once a fee is processed in Bitcoin, it is irreversible. If there is a chain split on the domain records due to a formatting/authentication dispute ... those Bitcoin transactions may be going to an authenticator who in fact never did get the registration done because the majority of the network has ignored that domain registration block
That doesn't really reflect how it works. If there is a chain split, eventually the network will settle on one of the chains. The generator that mined the block in the "winning" chain gets the transaction fee.
There is no "irreversible" payment to the generator in the "losing" chain. Well, in a sense it is irreversible but as they can only spend it in the losing chain it's not much use to them.
