Probably some huge bad luck

Looks like such pool is under attack by the bad share exploit. Has been for 8+ hours now.

I checked logs and there was nothing that stood out. I also noticed hashrate charts and they look normal http://uswest.mine.nu:7903/static/ Does look like the odds were forever NOT in our favor  

@chaeplin

Do all pools need to update to latest source ?

Do all pools need to update to latest source --> no.

Tested. All share rejected.

p2pool code, attacker got nothing. p2pool no need of change.

Thanks for checking chaeplin!

Maybe someone can contact suchpool admin to have them update.

Edit: I have alerted them in IRC and yes they are under attack at the moment http://drk.suchpool.pw/index.php?page=statistics&action=pool

Yes if you check the stats page they are under attack http://drk.suchpool.pw/index.php?page=statistics&action=pool

No one has responded in IRC yet, but I have messaged all the relevant links in channel.

That poster on /r/bitcoin admitted that the latest DarkSend is indeed decentralized but pointed out that the specs don't mention anything about signing. As mentioned in gmaxwell's original post (https://bitcointalk.org/index.php?topic=279249.0), blind signatures are needed to truly prevent anyone from learning the sender-receiver mapping. Does DarkSend implement blind signatures? If not, are there plans to introduce it?

Yes, the implementation uses blind signing. All it cares about is that your input and outputs are there with the correct amounts, if that's the case you sign your input away to all of the outputs. When everyone signs like this, it's trustless and completely secure.

SuchPool is over 51%, with two 1gh miners, and one 1gh miner on coinmine.pl. I thought exploit was fixed yesterday.

[meebs]

It's getting very annoying as well. The suchpool has been at 200% share rate for half a day now.

Guys, you may want to stop referring to the guy running the exploit as the "1GH guy" as there is an honest pool out there called 1GH (not mining Dark but still confusing).

Wtf why can't these pools limit the hash rate per worker

Well, the 1 GH/s fake contributor is taking a lot of shares while contributing false shares. He was on coinmine and lotterymining yesterday. Pool owner should contact the pool owners of lottery or coinmine or fix it by himself:

Hi - 1GH guy on coinmine pool is (and was) valid

EDIT: and my pool was not exploitable

The question I'd like to know is why on EARTH are they running a gigahash rig through a pool... Surely that's enough to solo mine extremely profitably for the foreseeable future?

They'd have to set up a wallet somewhere and point all those (thousands?) clients there.

And the wallet being somewhere on a computer they can trust, would potentially mean that they could be traced.

Great news! Thanks for the fast response. Cheers!

Aha I see now. So basically what it comes down to is it's most likely a botnet or other illicit group of machines, and having it point at a mining pool stops the owner being accountable for their connections. I don't see why they don't use P2Pool if trust is such an issue. That would fairly immediately stop the network being so close to a mess all the time, and almost nobody's fees are high enough to make it pay out less.

It could also just be someone who is looking to burst mine every once in a while when they get a block of compute from a provider like amazonaws. Or they run another cluster that mines when other cores aren't in use.

But in that case, surely it would make a lot more sense to mine legitimately, rather than pushing so much hashing power onto a pool which is already perilously close to owning over 50% of the network... I mean, a single machine on any cloud host could provide a private P2Pool node to mine on. It just seems very suspicious to me is all, considering where they're choosing to mine.

Burst mining also doesn't make sense because coinmine is PPLNS not PPS. It's an incredibly inefficient way to mine if you're only using it in bursts.

If DRK is too hard to mine, then what is needed is a DRKMultiPool. Similar to what BlackCoin is doing: http://www.blackcoin.co/mining/want-to-mine-blackcoin-again/

Anyone have the skills/time to get this up and running. We could spread darkness over all the shitcoins out there...

I have to admit that this sounds like a great idea. I would to see a darkcoin multipool work like this. Can anyone make it?
