Was it mentioned if the hacker/white hat was going to return the BTC that they withdrew?
If they don't return that BTC, Poloniex would be out of pocket in a huge way.
I hope we can pull together an adequate bounty for the white hat such that they will return all BTC.
He said he would, but I haven't heard from him since he explained the vulnerability. My guess is he is waiting on the block chain rebuild to see where he stands with XCP.
If all the XCP gets returned to the Poloniex account, then the dump will stand, and he can keep the BTC. If not... then let's hope he returns it, and I'm going to have to roll back some trades.
Hmmm...its still feeling like the fair and reasonable thing to do under the circumstances is to offer the hacker a fair-market rate bounty for identifying the exploit... Then the onus would be on the hacker to choose how s/he will be remembered in history.
Either s/he chooses to become a whitehat, a hero. And can live with fame, personal pride, and good karma ... not to mention much respect, trust, and future opportunity from within this community!
Or s/he chooses to be a blackhat, a thief. And inevitably experience some guilty conscience, maybe loss of sleep, bad karma in this life ... possibly the next life too =(
Lets get this bounty sorted out, and then hopefully our hacker will make the right decision!
