Information on attacks

100 confirmations on btc-e because of the attack.
Is the attack over? If yes why btc-e didnt decrease the confirmations? -
I dunno but I’m more than a little upset by it! :(

the reason is that we can be under attack and it’s when they need to be ready. so it’s preventive of a new attack. they can’t detect the attack before they get potentially screwed so can’t adjust the confirm in real time so they stay safe.
we are in big danger when the hash rate is below 1.5Gh/s like yesterday. when we are mostly over 2.5Gh/s we are on the safer side as far as we know from previous attack. between 1.5 and 2.5Gh/s we are in danger zone, but the attacker has to coordinate a bit and some luck-bad luck can make the attack more or less difficult so can require very long attack to orphan the original chain or even fail.
if I was BTC-e I would not lower the confirm either unless FTC has a minimal legitimate 2Gh/s. we can’t guaranty that 2Gh/s at all time now so they need to stay in the safe side with high confirm number :-[

We’ve had it well below 1GH/s yesterday before the last retarget. If someone attacked us at that moment, we retargeted faster and gained additional hash power from returning miners. As long as our profitability is comparable to LTC, there is no reason to worry about. We’re stabilising. The difficulty roller coaster is getting tolerable.
