You must feel really superior.
LOL, BlackHatCoiner thinks he can modify the timestamps at will, so nothing is holding you back.
If you're the only person in the network, then you can decide which timestamps you'll use between the blocks and increase or decrease the difficulty analogously. You can't achieve this if there are other miners too, because they'll mine fairly and outpace your blocks. Only if you owned the majority of the hash rate and did the whole work by yourself until you exceed them, you could replace your chain with theirs.
any wallet client will not check the proof of work verses the other chain.
I wasn't talking about the wallet clients. I was talking about the Bitcoin clients.
At least that is the way it works in this reality, not sure about the fantasy world you guys seem to live in.
