<p>With unlimited money, you could destroy almost anything. I don't really see why it matters. If someone with unlimited money spends a few billion dollars to destroy Bitcoin, we'll just create Bitcoin2 and maybe he'll spend another few billion destroying that. We can keep creating new crypto-currencies indefinitely. If each one gets a few billion dollars out of the hands of some evil entity, that's a win in my book.</p>

Doesn't work this way: if you destroy one currency, the trust in the next one would be back at zero...

Quite the reverse, the inflow of billions of dollars will spur *massive* interest among people trying to get a piece of that money.

<p>In fact they can. Somebody who could raise 20x of the entire network's computing power can rerun the transaction history from the beginning, throwing out any transactions they don't like. So long as the rest of the transactions are consistent, they should be able to gain the trunk blockchain line. This would make the entire blockchain we have been running up to this point a very large split.</p>

<p>I was reading this interesting discussion in the comments section on ZH where this guy was talking about how a single entity (think corrupt government and banksters) can throw money and processing power at will at the network to successfully manage a 51% attack or just cause havoc in the system by sending incorrect network messages, such as denying valid transactions or allowing invalid transactions. </p>

<p>Can someone please comment on whether this is possible and if not, how does the bitcoin algorithm/ecosystem counter such an attack</p>

@NickODell i've clarified the question further. i guess the question is not ALL about a 51% attack like i posted earlier.

With unlimited money, you could destroy almost anything. I don't really see why it matters. If someone with unlimited money spends a few billion dollars to destroy Bitcoin, we'll just create Bitcoin2 and maybe he'll spend another few billion destroying that. We can keep creating new crypto-currencies indefinitely. If each one gets a few billion dollars out of the hands of some evil entity, that's a win in my book.
