by re-mining the blockchain do you mean that that one person could keep on making money?

@97980: No, I'm referring to the fact that they could create multiple forks of the block chain which diverge after a certain point.  This wouldn't gain them any extra money (because shorter forks would be invalidated), but it would let them undo previous transactions by including a conflicting transaction in the new fork.

<p>Let's say that, hypothetically speaking, someone had the mining power to mine all unmined bitcoin(I believe around 6 million bitcoin, correct me if I'm incorrect). Would they confiscate it off of them? Would there be some kind of software barrier? which would mean that even if you had such great mining power, you wouldn't be able to mine so many bitcoins.</p>
