why do you think casey had any malicious intentions towards bitcoin? my best guess is he was just some guy that wanted to invent something and he had no idea or anything about anything else. lets not label him as a bad guy without some type of proof. maybe he's dumb because he didn't know he was opening up a pandoras box but dumb does not equal malicious does it?
I have a hard time believing that someone who is capable of finding an exploit in the protocol hidden in the verification rules and not publicly known, is someone who is "dumb" and doesn't know what he is doing.
Find a better solution.
Well, we first need to get everyone to agree that we need to fix this oversight that is being exploited then begin arguing about the fix. Right now there are still people who either say "it will go away on its own" or claim "there should not be any fix at all".
