I still don't understand what will happen with all the attacker's "fake" transactions once he published his longer chain to the public? Surely those transactions will be republished/rebroadcasted to the public pool and available to get selected by other miners again to be included in their block (to be confirmed) right? So what's the point of creating your own chain privately and publishing it once it becomes the longest one if your old "fake" transactions are still able to be confirmed down the road by other miners? Are you saying once the attacker's transactions got confirmed, he has to do the same process all over again? (creating a private chain and broadcasting it once it becomes the longest one) Thanks.
