We where today attacked with a scam attack, it has been dealt with, and im considering legal action for trying to
cheat the pool, and thereby the users out of coins...

It's good that you want to help your miners out. Much respect. But Im curious as to what exactly happened? I noticed the official pool is still getting A LOT of orphan blocks. Could there be something else deeper going on?

Ok, to summerise, without disclosing too much info for others to try on other pools:

that guy with the huge "mining speed" was using a weakness in the stratum code, i notised a weakness in the way the pool got the shares
and set defences up to prevent that kind of cheating, in reality he did not have that kind of mining power, and his shares wasnt worth anything to the pools overall progress. if you look at all the blocks discovered, why did hes miner not discover ANY blocks at all, we should have been getting loads of blocks with that kind of speed, so i investigated, together with evan we set up a fix, now, next time he tries, the system will automatically ban him for a week. he tried connection through a proxy but already he was unable to get that kind of speed that he had at first.
so that tells me it works as it should.. i also banned his ips from the server. and disabled automatic payout from his account.

regarding the orphants on the official pool, i think we got that sorted out as well...

Glad to hear that there's progress about fixing stratum exploits.

Any chance you could get Evan, or someone who has a clue what's going on, to comment about the difficulty? Some blocks its 150, some it's 300, then we get a spike and its around 800. Normally I'd let it slide, but the most recent spike was over 10k . . so what's going on?

I've seen plenty of KGW implementations but haven't seen crazy swings like I've seen with this coin. Has this already been talked about before in the tread?

KGW has only 1 goal in life, to keep the generation of blocks at the target time, if it changes, it will also change the diff to try and counter any blocks being generated too fast... regarding the 10k spike, well, i can only speculate...

so will he be able to do this on other pools and p2pools as well?

Maybe someone could answer this one for me. Is Darkcoin ASIC resistant? And how does it compare to Vertcoins Scrypt-Adaptive-Nfactor? I am actually a DRK supporter I just want to understand how script ASICS could affect the coin and how it compares to Vertcoin in this regard. Thank you.

Darkcoin's asic resistance is mainly do to the quantity of different algorithms that need to be implemented. asics could be made, however it's just a lot more work than making them for a single-algorithm coin. Adaptive-nfactor is much more effective asic resistance, as the memory requirements increase over time, so even if asics were to be made they would be rendered useless over time.

I think it isn't as ideal as it sounds for adaptive-nfactor. I mean if someone equips an ASIC board with, say, multiple times the RAM that current GPUs have, they can have a significant advantage in raping the coin. If the coin "adapts" to a higher memory requirement, then it'll lock out the current GPUs that most ordinary miners use - furthering the ASIC advantage of the whale who is already ahead of the GPUs. Am I missing something?

Every time this happens they disappear in short order due to KGW, so not really anything to worry about when you see it. Just a whale that finds the pool closing in on him

The daemon reported the hashrate at 280Gh for a moment, which is insanity. That can't be true

have we surpassed bitcoin hashrate yet Tongue

The actual equipment necessary is tremendous if it were to do this naturally. Boiling everything down to i7 processors and r9 290's . . in order to double the difficulty . . you need double the equipment. Looking at suchpool.pw . . the net hashes right now are 12g#. Taking this as normal with 306 difficulty . . then the hashes number would need to double to take it to 612 difficulty. Then double again to take it to 1224 difficulty. Then double again to take it to 2500 difficulty, again to 5k, and one last time to 10k difficulty. This ends up being 2^5.

So @ 12 g#, we'd need about 5517 R9 290's . . or about 33k i7 processors just to have it there now.

Doubling this . . 11304 290's, 66k i7's . . about $5.8 million in just GPU hardware ($21 million in processors)
Double again . . 22068 290's, 132k i7's
Double again . . 44136 290's, 264k i7's
Double yet again . . 88272 290's, 528k i7's
One last doubling . . 176544 290's, 1M i7's

Also, normalizing to Scrypt . . a 10k difficulty for this coin is a difficulty of 3872.

Last I checked no one person had pretty much the entire Litecoin network in hashing power . . so I really need to lean toward a bug or serious exploit in the difficulty retargeting algorithm.

Someone please let me know how far off I am.

Thanks for this.

Just a shot in the dark here (no pun), but could beta v3 have introduced any bugs vis-a-vis difficulty/nethash? It just seems way too high even now though it has dropped (to the 700s Roll Eyes

)

There is no guarantee anywhere. If there is money to be made to create an ASIC that can handle all 11 algorithms, someone will make it. I don't think we'll be there for at least a few years, but then what do I know? Everything happens faster now than with the original Bitcoin.

DarkSend Beta Version 3.5 (v8.9.7)

- Session ID's are now tied to the blockHeight, so they'll be much more stable. Some users were reporting stale DarkSend messages all of the time because they couldn't sync.

Documentation:
http://darkcoin.io/downloads/DarkSendv3.pdf
http[Suspicious link removed]] http[Suspicious link removed][/url]
Ubuntu 64 qt: http://darkcoin.io/downloads/beta/darkcoin-qt
Ubuntu 64 daemon: http://darkcoin.io/downloads/beta/darkcoind

What's Next?
The next update is going to be a big one, it'll probably take me a week maybe.

Currently the network uses 1 master node, so it's a centralized implementation. I'm going to write some tamper proof logic to pick a random node from the network and elect it as the master. This is a neat implementation, because when you leave on your client it supports the network and you'll randomly receive fees when people try to attack DarkSend ( or turn off their clients in mid-transaction, lose their internet connection, etc ). We should see a really healthy amount of full nodes because of this, maybe even more than Bitcoin itself eventually.

I may want to make out with you. But totally not in a gay way.

I'd make out with you too, except I'm old and icky and it'd be like making out with my kid.... ooooh, gitting REALLY goss now!
