Someone buying at .0075 and selling at .001 is not trying to trick anyone.  It's just plain awesome, and I hope it continues.

hey guys!

Quick question, anyone have any coins per day/ hashrate at this time for Darkcoin? Considering switching my miners over but would like to see what i can expect.

Cheers!

I don't think anyone can really say with any accuracy.  The difficulty is bouncing all over the place too much to be able to make a solid prediction

[tifozi]

For a rough guestimate at the current rates,

Dark-Bot`> DarkCoin [DRK] estimated income for 30000 KH/s @ current difficulty of 171.4927 = 3.44 DRK per hour (0.00652855 BTC/$3.98 USD), 1 BTC in 6.38 days

I have 4 280x tweaked to run @ 9 MH/s for a rough payout of ~24 DRK/day for the person interested in the throughputs.

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.

I sent this conversation to a friend that is very capable in these fields, and this was his input. For your thoughts/ consideration:
====

I would have gone another way. It would go something like this:

-          You submit transaction to block chain

-          The block chain server = miner (?) gets your transaction + 100 other transactions

-          He sum all and randomly breaks to small pieces and adds to blockchain. So receiver gets coins from 1000 addresses instead of one

-          Payment is sent in batches so you do not figure out based on the sum (in case that its 5.34234) that x paid y.

 
Dealing with transaction id:

-          Transaction id is generated client side. probably several ids that need to go with each chunk of coins

-          Transaction id sent with the coins to receiver

-          There should be some private key public key verification so sender can prove to receiver that he sent the coins. Sender will write in comments “$ sent from john” and ony receiver can see it.

The only point of failure I can see is if miner keeps log of who sent and where

So far I've bought a few hundred at around 0.0012/0.0013, twice. Pretty awesome, whoever's doing that, at least so far.

[cshlock]

is c-cex down for you guys right now?

[flounderella]

Since difficulty is through the roof, I stopped mining. Its easier to just buy with BTC at this stage instead of getting the same coins mining for 30 days

[traumschiff]

is c-cex down for you guys right now?

Down for me also. DDOS maybe?

http://www.downforeveryoneorjustme.com/ lists it as online and another status checker website also but shows 300-400 ms to c-cex, so my best guess is ddos.

Really bad, withdraws not working/slow as hell and now this..

and if u try generating an LTC deposit address now?

[deeppurple72]

ill check out the p2pool-quark fork,

could you post the bitcoin network.py settings you are using for darkcoin ?


especially these:


        BLOCKHASH_FUNC=
        POW_FUNC=

        SANE_TARGET_RANGE=
        DUMB_SCRYPT_DIFF=

thanks.

settings please

I'm betting on someone is trying to do a major buy because we are about to be listed on a major exchange, I had been watching the markets pretty closely the last couple days and someone appeared to be trying their hardest to keep the price less than .002.

Me too, and I completely concur on the whole sub .002 thing.

What a bargain!!!! Pile on guys...

what major market will dark be added to?

If you don't like to read FUD then skip this post.

I don't know what is going on but what would be better way to get massive incoming DRK and BTC deposits than faking some crazy buys and sells. The site must have all time high amounts of money right now.
