lol, how is this effectively different than a premine?

Neither the devs or anyone else got a fixed % of coins at the beginning. Doge is not premined either but people who start at the very beginning get the benefit of making coins more easily. That's not how you see it?

That's the way it is supposed to be.

The block reward formula's + KGW == Whale Harpoon. It see it as being a critical part of the success we've seen thus far.

Something else to consider:
If (for some reason) the difficulty rate of DRK went back down because people stopped mining it, the algorithm encourage "coin CPR" because once the difficulty drops, the rewards become higher, hopefully encouraging more mining... and more interest...

I just wish I knew about darkcoin earlier I'm not here to say insta or premine but it takes more hardware than I have to get anywhere. And let's be honest its not even 2 months old. I'd consider that an early adopter I just can barely get coins. I still help market dark though and hopefully will have good news for all of us soon! Some people are willing to give me some coin love.

• Block reward is controlled by moore's law: (11111 / (((Difficulty+51)/6) ^ 2))

Please help me to understand.

Block 22067:
Difficulty: 57527.019
Generation: 22 + 0.004 total fees

11111 / (((Difficulty+51)/6) ^ 2  =
11111 / (((57527.019+51)/6) ^ 2 =
= 1.207 * 10 ^ -4
!= 22


So I understand the block reward formula in the wrong way. Please explain.

Also, as 22 is a whole number, there needs to be an INT() or round(__,0) somewhere


thanks :-)

The GPU formula is a bit different, we switched to it when they became available via blockchain folk. It's 2222222/(((x+2600)/9)^2)  and it's modeled to better represent the variance of difficulty that they bring to our mining pools. i.e, under CPUs a move from 1 to 10 difficulty was large, but under GPUs a move from 100 to 110 is nothing.

You didn't read a word, did you?

Of course I did, but I'm failing to see the practical difference between simply handing a disproportionately large amount of the coins to a select few controlling entities, and awarding them the coins after a (mostly) trivial amount of mining.  You can theorize about the altruistic and right-minded nature of the founders and early adopters (and I'm certainly not saying you're wrong), but those same arguments could just as easily support pre/instamined coins.  At the end of the day, they control a significantly larger amount of coins than the amount of work they put into mining them relative to those that come later, regardless of what they choose to do with them.  

I should note that I'm not begrudging them the right to do whatever the hell they want with their coin.  I've never understood the people that bitch and moan about premined coins, like it was their God-given right to a fair shake for a particular coin.  Maxcoin is a great recent example. Personally I just vote with my hash power and go elsewhere if I don't like a coin or its profitability is low.  I like Darkcoin and would probably buy into it if I weren't risk averse and tend to avoid speculation.

Other ideas?

I’m open to ideas on how to provide the best security to the network. I would love to hear what people have in mind.

How about adding an option for adding decoy transactions?

Sometimes coinjoins can be picked apart just by looking at what adds up. This was painfully obvious on the darksend testnet the other day, as I remember seeing darksend transactions like Inputs: 500, 5 Outputs: 400, 100, 4, 1 where there's only one possible solution of who sent what.

One could easily construct decoy transactions to specifically add up to the amounts of the legit transaction. For example:
Intended transaction:
Input: 100
Output: 20, 80(change)
Decoy transaction:
Input: 500
Output: 10, 90, 50, 50, 35, 65, 95, 5, 100(all sent to change addresses)

If that decoy transaction is coinjoined with the intended transaction, there becomes 5 extra possibilities of where the 100 was sent to even if no transactions by others help mask it

Also, use more inputs than necessary, and use several change addresses instead of just one to help mask the intentions, and also having more and smaller outputs causes it to be more likely that they can be useful to help mask other transactions joined with them.

The testing we did was just a test of the transaction pooling and remote signing of inputs, not a test of anonymity (good eye though checking that out). One of the next tests we should have that working.

Here’s the plan for anonymizing amounts if anyone is interested:

DarkSend anonymizes unique amounts like 15.15 by using “denominations” of currency in the different transaction pools available. These denominations come in the amounts of 5000, 1000, 500, 100, 50, 20, 5, 1, .50, .25, .10, .05, and .01. For example a payment of 15.15 would be broken down and submitted to the following transaction pools:

Submit payment for 10DRK to addr Xyz using pool 10  (in pool 10 ALL outputs are for 10DRK)
Submit payment for 5DRK to addr Xyz   using pool 5     (in pool 5 ALL outputs are for 5DRK)
Submit payment for 0.10DRK to addr Xyz   using pool .10
Submit payment for 0.05DRK to addr Xyz   using pool .05

The four payments total 15.15, just like paying in cash, except you have no idea who paid you.

Users receiving anonymous payments will then receive separate out of order payments for various amounts adding up to the total amount they were intending on receiving.  

With this methodology, payments could be as granular as 0.01, this could be changed in the future if the currency becomes more valuable by adding smaller denominations.  

That sounds great, and far better than anything I thought of. Your denominations seem a little weird though. Several of them have rather limited usefulness ( 0.25 -> 0.5 -> 1 is only double each step), and the lack of pools for very low amounts seems like a strange choice. Is there a reason you have all those close amount pools rather than a pool for each 10^n? (1, 10, 100, 1000, 0.1, 0.01, 0.001, etc)

Decoys might still improve that pooling system though. As the payment is broken down, an address belonging to the sender and the output of the send will end up in a transaction together for each part. If the sender has received most or all of the coins to one address, or if someone watching knows multiple of the sender's addresses, they might be able to connect the source and destination by looking at if known addresses of the sender, and any output, are always in the same transaction with each other over the duration of the transaction. By using decoy sends, you can add in parts where the sender's addresses are seen in a block, but the intended destination is not, making analysis more difficult.

CPU DRK mining question:

I'm using the fantastic darkCoin-cpuminer-1.3-avx-aes-windows-binaries, with these settings:

Code:

minerd-corei7-avx -a X11 -o stratum+tcp://drk.lotterymining.com:4444 -u username -p password -t 8 -q

My proc: Intel Core i7-3770K, 3.50 GHz

I've been consistently getting 490+ khash/s with those settings, which I think is pretty great, but I'm not sure what others are getting with the same or similar proc.

I've been consistently getting lines like this:

Code:

[2014-02-21 22:01:06] accepted: 43/43 (100.00%), 490.02 khash/s (yay!!!)

But as of this morning and after about 50/50, I've been getting lines like this:

Code:

[2014-02-21 22:22:17] accepted: 77/78 (98.72%), 486.72 khash/s (yay!!!)

Concerning that percentage, 1) what does it mean exactly, and 2) why all of a sudden (after about 2 weeks worth of mining) am I getting less than 100%?

Thanks in advance for helping me with my n00b question! 

I'm also mining on a 3770K and getting more or less the same performance. If your percentage is less than 100% that means you've submitted a stale share(s) ("boooo" instead of "yay!!!"). In your case 1 stale share, hence the 77/78 instead of 78/78. Not anything to worry about unless the percentage drops significantly.

My 3770k does about the same.

And as raze said, one stale share is nothing to worry about. It's consistently stale shares that indicate a problem. A share can go "stale" if your pool issues you a hash to solve, then someone finds the block before your computed hash is submitted. this can also happen if there is some sort of network delay as well.

Many thanks to raze182, HammerHedd, and meebs for responding! I appreciate the insight.

This is frustrating, since last night I'm now down to 24 stales on average:

Code:

[2014-02-22 12:18:49] accepted: 1440/1467 (98.16%), 475.63 khash/s (yay!!!)

I'm going to try a couple of things today: 1) I have a new awesome crazy heatsink to replace my stock Intel with and then I'm going to gently overclock to see if that makes any difference and then 2) I'll try a different pool for a bit (but not blaming the current pool at all) to see if that changes things any also.

I would be very happy with 98% accepted shares.  My reject rate mining darkcoin is currently 4 to 5% (95% accepted).  The only coin ever been better than that for me is litecoin.

I just wish I knew about darkcoin earlier I'm not here to say insta or premine but it takes more hardware than I have to get anywhere. And let's be honest its not even 2 months old. I'd consider that an early adopter I just can barely get coins. I still help market dark though and hopefully will have good news for all of us soon! Some people are willing to give me some coin love.

You still get more darkcoin than you would have got in litecoin when litecoin was worth the same as what darkcoin is now.

wow why darkcoin droped 40%

[blueforever]

a few people picked up a lot of drk for cheap! Wish I had some buy orders that low.

Someone probably fat fingered an order.

With most new altcoins an "early adoption" period for regular miners lasts less than a day after launch or sometimes even less than one hour

[BitcoinSteve]

I have 110 dkc  value in a year?

[shackleford]

So what's the rationale for this block reward system? (11111 / (((Difficulty+51)/6) ^ 2))

As I understand it, the TOTAL distribution per unit time will come crashing down as network hashrate goes up. Not to mention each miner is getting a tinier slice. That's rather discouraging.

Apart from Darksend, I think this is the best feature of the coin. All other altcoins become diluted if they doesn't become a instant success like Dogecoin.

So the early adopter edge becomes even more overwhelming? Nice way to kill a coin. An exchange medium is only worth something if others agree and also have a stake. We'll just end up a small group of hoarders waiting around for something to happen. Reminds me of QRK.

Now, I know it may seem unfair to latecomer miners and some trolls even went as far as trying to discourage people by calling this a instamine. But the thing is... the vast majority of coins have a high percentage owned by early adopters.  That is the reward they get for believing in the coin before anybody else.  Due to the diff/reward system Darkcoin might be a little more extreme, but as I just explained that system has a very important purpose.


Tldr; This is a fair coin. The diff/reward is a feature that allows more fine control over how much coin is released into the market and thus prevents manipulation by whales who plan to dump.

I don't know how you can consider 1.8 mill issued the first day anything other than an insta mine (12.5k issued last 24 hr). Anyone with 1/8 a brain knows why this happened as is the case with most alts.

"That is the reward they get for believing in the coin before anybody else" This is a joke right? There was little/no notice and if if you were lucky enough to be on the forums at the time, and had waded through the 100's of crap coin threads to see this than it was pretty lucky. If you are saying it was foresight then you are lying to yourself. After problems the dev even told a guy he would schedule a relaunch then proceeded anyway. .. can't loose that element of surprise now can we.

 I look forward to the fork without the self serving launch and reward structure (halves in 1 year lol).
