if you're asking if negative input is legal, yes it is. To simplify it, it's similar to how modulo operates in C. If you do: int x = (1-3) % 5; // -2 % 5
you'll get "-2" as a result, but what you're actually interested in is: int x = (1-3 + group_order) % 5; // (-2 + 5) % 5 = 3 % 5 == 5
group_order == 5, and you'll get 3 as a result... Yes, I know. So, the problem is that -2 or 3 is processed further and we are not certain if -2 behaves differently than 3 does. That is certainly a problem. EDIT: we are not certain if the 3 resulting from a -2 is process the same way as we would give it another try. "-2" is passed as input to verify() which was expecting to see "3" not "-2"... But it is not sure, if -2 in form as a 3 would result in the same outcome as it would be a 'real' 3 from the beginning. In math -2 mod 5 equals 3. Is that the result, which is wanted? ... in that case C implementation is wrong there and should not use % with negative numbers. (change to positive by adding 5) I think that's not the point here. Consider this: b = f(a)
c = g(b)
d = h(a, c)
Let's assume c results in -2 with a certain b. Even if c=-2 and c=3 are interchangeable mathematically, h might not work as expected as the pair (a, c) belong together. So, it could be the case that h(a, -2) != h(a, 3) for the very same a. This must be avoided at any cost.

I think people are getting too excited about it - it's not a bug that really affects anyone except for perhaps exchanges who are relying on the tx hash to check whether a tx went through or not (if you are using bitcoin-qt this wouldn't affect your balance at all).

what would it take to do better at our public relations face? cannot sleap, too much weed.. - I am finishing the text "Decentralized internet and Nxt solutions", so I hope it will get some comments from the community and them we can send it to big mainstream media and get attention from guys like Kim Dotcom or Assagne. As was said, contact with Kim is possible, but we need to show him this text first  Somehow, when I asked the question of how to do better at our public relations face, I didn't think the answer would be too much weed, Kim Dotcom and Julian Assagne.  HAHA, I usually dont post that... much when i doo... well...im drunk

Simple mode....
ACTUAL/NOW/CURRENT:
1) you send 1000 NXT and NXT 1 fee 2) shows that balance (false) / show is received at the destination (false) 3) it is effective in 1440 confirmations (after 48 hours) 4) someone forge the commission NXT
WITH CANCEL:
1) you send 1000 NXT and NXT 1 fee 2) shows that balance (false) / show is received at the destination (false) 3) you cancel the transfer before the confirmation 800 (~24 hours). you recover the amount, the recipient returns to its normal amount. 4) someone forge the commission NXT
___________________
Because you think DGEX and the other sites take so long to process transactions? Are not congested. Are only waiting for 1440 confirmations.

WE SHOULD START TO BUILD NXTMONEY == fixed price/value in all major currencies.
We need economists for that or u will end with eMunie-like system. I still doubt that eMunie "constant value" idea will work if people start selling EMUs. Can't see how it will work. The system doesn't even the variation of price, it just alters it. Obviously, it will look more steady when there is a lot of demand, but when people start selling, there is nothing to shrink the supply or enforce the demand...
