Some users have been asking me questions about what happened with the pool and KGW exploit. They were confused that the two were somehow connected and I thought I would clear it up.

Pool Exploit

The pool exploit was due to a miss-configuration of the stratum mining software that allowed miners to submit lower than normal difficulty shares. These shares were technically worthless and should have been invalid, but the software couldn't tell. If you're pool is still affected by this, here is how to fix it.  

Use the branch "Feature(MultiAlgo)" from this repo: https://github.com/Crypto-Expert/stratum-mining

After cloning that and checking out the correct branch, modify algo/coindefinition.py to use xcoin_hash.

Here's an example configuration for Darkcoin: http://paste.ubuntu.com/7116297/

KimotoGravityWell vs DarkGravityWave

We recently experienced a spike of difficulty from 300 to 10048 for one block. This was done by using a timewarp exploit on KimotoGravityWell where the user would submit an invalid timestamp on a block. To fix this issue without causing any unintended issues I implemented my own difficulty algorithm called DarkGravityWave, which uses 2 Exponential Moving Averages and 1 Simple Moving Average. These respond very quickly to shifts in the hashrate, but when invalid timestamps appear they can't impact the difficulty like we experienced before.

I just compiled a new node list, not complete yet. Its p2p pool nodes and random connected nodes to my other nodes, all those nodes are pretty much 24/7 currently.
try at your own risk

i just loaded a fresh compiled qt wallet wit hthese nodes in 3 minutes

Is there a proper solution to get the wallet to sync past block 34139?

I started with no user data and a freshly compiled wallet from newest github revision, the nodes from 10-20 pages back and still no full sync. Tried without those nodes, again no user data, and same issue.

Any help?

It appears he updated. I don't know if it's a final draft though.

I think DRK is approaching a mass where the bot won't be able to keep up, unless it is profoundly well funded.  Not quite there yet, but for now I'm happy to continue soaking up as many sub-13 DRK as I can afford.

Ahhhh, I am so missing this as I needed to pick some up

@chaeplin

Moved my rig out. Thanks for the heads up.

I take my words/thoughts back.

I observed the trade very closely today, and i come to realize and admit-
THERE IS someone dumping drk, pushing the price down, slowly but surely.

Althouygh I must admit that since most of us here are realy keen on this coin and hold our coins closly, this guy is going us a favor helping distribute the coins to more people. 

But coming back to the price manipulation, even if we exaggerate to assume he has 200k coins (6% of all coins circulated), and he dumps 10k coins every day (he dumped over 6,000 coins in the past hour), then he will be out of coins in 20 days...
I estimate that's exactly when we will be set to launch from beta into open source...
as the saying goes - "bring it on..."

There's still some major price manipulation going on at Cryptsy on DRK by bots

To p2pool users who use

http://uswest01.mine.nu:7903/
http://uswest.mine.nu:7903/


Please choose another node closest to you.

darkcoin p2pool node finder is http://darkcoin.mine.nu/


I setup the server for p2pool BOOTSTRAP_ADDRS.
Darkcoin p2pool has at least 18 nodes.
BOOTSTRAP_ADDRS will be updated.

uswest.mine.nu(uswest01.mine.nu) will be down, when current 5 miners change their rig setting.

Don't we have a Technical Writer among us to take on the updates/revisions to that document?

Excuse my French, but Evan is a fucking genius!  I honestly don't think I have seen some much innovation in any coins to date, since bitcoin itsself.

Keep plugging away Evan! You're building a very loyal fan base, and for good reason!

https://c-cex.com moved to much faster server. We can now handle 10x times more online users! Welcome!

Good stuff. Consider writing it in TeX though for it to look a bit more legit.

Consider it! I think it makes Dark the most anonymous coin by a longshot. Pretty much complete anonymity. With DarkSend you have plausible deniability, but the ability to assemble transaction history via amount matching makes it a binary search tree (mostly, assuming people aren't sending to more than one address, as most users will do) that can still be somewhat traced (becoming increasingly hard to track further back in the transaction history). This implementation destroys that ability completely.


edit:
If you wanted you could bake the functionality into the clients themselves. They could generate the addresses and do the denominating, passing that information to the master node as regular transactions - as you do now. I see in the whitepaper that you have the clients check with the master node before signing to verify no funny business, so this angle might be easier to implement on top of your pre-existing code. The master node would just need to verify that all outputs were denominated amounts, until the amount was below the lowest denomination.

Not sure we want to involve the word laundry or laundering but that's a genius idea.

So we really should get on the new trend of having our own profit switching engine that mines other coins and buys darkcoin like doge, mint and redd, here is the example I'm talking about http://mintpool.us/.  Maybe we can urge them to add darkcoin by giving them a reward, that's what worked on the owner to add reddcoin.

Missed this, man  you just keep coming up with better ideas!  You really think outside the box, I'm in awe!

Vote for Bter.

We need a chinese exchange too

And dont worry about not having that many votes. QQC is obviously copy accounts for spamming etc...

Yah, but think of it this way.  Evan has his name and face out there as Mr. Darkcoin.  He wants to, at the minimum, protect himself from future harassment in the form of Governments dragging him into every stupid thing people do with this coin.  I think it's a good move for him, as I don't want to see him personally dragged down if someone uses darkcoin to do something really bad. He is going to take this stand because he has to.  Don't let it rub you the wrong way.  I'm also not sure we need drug addicts and pushers to use our coin.  I'm banking on the future usefulness of it.  Unless cryptos become mainstream, they won't survive.

We're being discovered!
