Hi all! Another noob here... name's Ron. I'm bummed I just this week started investigating crypto$ because I might have been able to get a lot more of these DRKs! But, oh well. CPU mining about a tenth of a coin a day! (i7 870) - Just ordered a R9 270 to replace my old GeForce (I'm poor). So anyway... I've done graphics for years and when I saw the promotion stuff mentioned I started working on a 3D DarkCoin. I was disappointed to see that the promo team isn't interested in this but here's a few picks of the initial stages I may or may not get back to... Of course you are welcome to contribute to my well being and time. DRK donations: XpQZscB95M63vBewcyBWe9hgj4nMhBWi69 holy crap that looks amazing!

I wonder where we can get it to work into the overall picture.

The kgw exploit is real.
The problem is that the software will accept blocks that are timestamped earlier than previous blocks, (for good reasons) up to the median timestamp of the previous 11.
Kgw counts these as very fast blocks and adjusts the difficulty up by its 20% maximum. Once. But you can use that once to roll the timestamp back after five blocks that are long enough to drive the difficulty 20%lower each.
So the exploit is to start mining your own block chain, time stamping several blocks into the future far enough to get the maximum downward adjustment of difficulty each time. Then jump backwards in time getting the maximum upward difficulty once. Rinse, repeat, and your chain gets ridiculous low difficulty and you mine a whole lot of blocks while advancing your timestamp not much further than the main chain.
When the time in the main block chain catches up, you release your own chain and force a reorganization, which allocates to you all the coins mined for the last umpty ump blocks.

Thank you for responding . . I send a msg to BitcoinEXpress and then started looking at last posts and was actually gonna send you a message next. But it looks like you beat me to it. I'm seeing the regular drops to sub 150 difficulty . . in conjunction with 800 difficulty . . but using the logic you put in your post, can this be used to get to a 10k difficulty? Could this also explain the increase in recorded orphaned blocks?

I'm in the process of rewriting KGW for our purposes. I've spend a few hours thoroughly going through the code and I think I can come up with a better implementation that doesn't have these kind of problems. DarkGravity?

Me too, but I like the way Cryddit is willing to explain how this happens instead of just saying yes.

Agree on the 99designs comment. The above 3d renders looks really nice, not usable for a logo but great for a stock article image for the press or somesuch. I'm sure it'll get used. Can we get high res copies of each minus the watermark? We don't have a bounty for any art the community generates outside of vectorised logos, so feel free to create whatever you like and the community will donate if they like it & are feeling generous. 5 DRK sent to the artist.

I wonder if we could get Dooglus to do it similar to Just-Dice and Doge-Dice, I think thats the most popular model as its both investor/bettor friendly. A well run dice site requires a lot of trust since the house needs substantial funds. I'd invest 1000 to the house if Dooglus did Dark-Dice
