The fatal flaw is too obvious to be found easily.

If this is a fatal flaw, will it kill NXT?

Can it be fixed? I hope so..

It would kill anybody trying to just copy-paste NXT into a clone. Not NXT itself.

Well, I am pretty sure the fatal flaw is the following one:

Not the fatal flaw although yes "mining of account ids" that are "not protected by public keys" currently would be possible (still no easy thing to do as no-one has demonstrated having done so yet).

With CIYAM anyone can create 100% generated C++ web applications in literally minutes.

The fatal flaw is not as complicated an attack (as CfB has hinted at) and Nxt itself is *safe from that* (so think - why would it be safe from that?).

I have the feeling we might be disappointed when the "flaw" is revealed. Something like "the flaw can only be exploited when the chain is short enough" or maybe some strange assumptions have to be made.

I think that the fatal flaw won't disappoint u. It's so fatal that I can't imagine anything more fatal (or my imagination is very limited).

So if the copycat uses the current source code (0.8.12) to start a clone coin, could you bring it down within a day?

No, coz the copycat won't forge even 1000 blocks. Jean-Luc removed some code.

I didn't take a look at the current version, so let's say we take some version before JL removed "some code". Could you bring it down in a day?

I know this question may sound illiterate but, what does this means?:

Each flaw has a small description. Here r SHA256 hashes of these descriptions:
