I'm a bit rusty on my crypto-currency knowledge, but I seem to remember that there is the possibility of a 51% attack, wherein if an evil actor managed to control 51% or more of the network, they could basically wreak all sorts of havoc on the network, from denial of service, to double-spending of coins to rewriting of (recent) transaction history. As for feasibility, some mining groups have already briefly obtained 51% control of the network "by accident", but if you want to go the black hat route though, DDOS a large portion of the network, spin up a few dormant bots and presto, you have your 51%. So it isn't impossible to cheat, and certainly not impractical. This is a major problem. Has this problem been addressed at all?
