So I PMed Evan about this, but I figured I'd throw this out to the community to see if you guys could come up with a solution.
I've been thinking about the denomination of coins in darksend and I think I've ran into a problem.
If I want to darksend 954 coins from Address A to Address B, how will this be denominated? The most obvious way to do it is:
9 entries into the 100 coin pool
5 entries into the 10 coin pool
4 entries into the 1 coin pool
The problem is - it will be clear that Address A sent 954 coins to address B by looking at the block chain - it doesn't matter how much mixing occurs, 954 coins leave address A, then sometime later 954 coins accumulate at address B.
The only way I can think of keep it anonymous is if the coins are sent to multiple receiving addresses. I suggested a while ago in the thread that maybe multiple addresses could be concatenated together and used as a "DarkRecieve" address - this would allow multiple coins to be received in denominated fashion.
Another potential solution is to require that in order to send 954 coins you must have a total of 1000 coins, but this would be a really bad solution because if you just wanted to send 101 coins you would need an addtional 899 coins in your wallet to enter into the 1000 coin pool to ensure anonymity.
Let me know if you guys can think of any great solutions.
Need more brainstorming!!111 To use a cash analogy, if I give you £954 and nobody sees the money changing hands, and neither of us keep any record of it except mentally, then we have an anonymous transaction. If we are seen/photographed passing cash from one hand to the other, we're busted, or if records are later found, we're possibly incriminated. However you mix the transaction, currently there are partial records, at least on the sending end. DarkSend by itself does not provide perfect anonymity, no one tool can accomplish that. Other steps need to be taken.
Password protecting the goddamn wallet on startup would alleviate the sender-record problem at least. |

I might be overwhelmingly naive and optimistic, but perhaps its an exchange (BTC-e???) that is accumulating drk in order to introduce it and have the liquidity to support it...
NOW THAT WOULD BE SOMETHING!!!
If an exchange needs liquidity, it's doing it wrong or up to no good. They're not banks, they exist to swap money between customers and take a small cut of each trade, that's all, they shouldn't need stockpiles of whatever they list. I beg the differ. If BTC-e suddenly introduces drk trading, they have loads of demand, but no supply. Furthermore, no-one here in their right mind would transfer drk to btc-e in order to sell unless price skyrockets bcs we all understand the potential of such a move. SO, if i were them, i'd stack a pile of drk to introduce liquidity right from the start. But - it's all hypothetical... If BTC-e introduces DRK, sellers as well as buyers will come and the market will dictate the price. |

Is it really a good thing to have one guy owning 5% of the coin? Seems worrying. Hope it's an exchange or pooled investment address.
There are bigger whales -- at least one person with 300k and another with 200k and likely a few others. This one just happens to hold it in a single public key (which is generally bad practice). Honestly I wouldn't worry about these large holdings. DRK doesn't have the liquidity to handle such large amounts so they'll be holding for a long time.

Much more worrying would be a situation like BTC, where there are at lease two individuals who admit to having >10% of the total hash each. One is the owner of KnC, surprise surprise. |

Hashes @coinmine safe? Cant access the pool, but my miners getting accepted shares. Anyone to clarify?
there was a post earlier to say its now working and they are trying to get website going. Thanks bro, do you know whats that 45.8% unknown pool at the pools hashrate chart? It's not a pool. It's all the hashrate that comes from other sources, beyond the known pools. If you solo mine, if you have a big rig, if you have an unlisted pool, it's all in the "unknown" pie slice. So someone is having almost 51% and is unknown to everyone? What gives? edit: down to 34% now, but still.. No, what I'm saying is that this slice does not represent 1 person. It's the sum of all solo miners, fpga miners, large gpu rigs that mine without a pool, small pools that are unlisted, botnets etc etc. +1 so everyone selling stop being lemmings. You are giving cheap dark to people. DRK in wired article on monday. This is healthy, I have no idea what the plans are of whoever has acquired hundreds of thousands of DRK in the last few days, but I'm pretty sure they have more vision than the average ADD crypto nerd. I suspect there will be a mighty influx of butthurt whiners when the price rockets up again. This guy keeps stacking... added another 10.5k to his stash today, currently standing at >200k DRKs. Yep, I predict much butthurt from whiners. To be fair, I also predict some gnashing of teeth from myself, because I could pick up a lot more DRK, it's just that the wife would certainly kill me if it all went wrong. |

I make up about 25% of my p2pool nodes hashrate, and they find blocks reliably, avg. 40 mins. May give solo a try.  If I can work out how.  your node probably finds one block per day or less. 40mins is b/c whenever any node finds a block you get paid. Simple math tells me you're right. But I enjoyed the happy fantasy of 10-15 DRK payouts three times a day for the few minutes it lasted.  Note to self: post-siesta coffee and cigarette first, before jumping onto the intertubes and posting nonsense! |

Just thinking... as the blockchain will grow up forever, is it possible in the future that only the masternodes will have and keep it if we have more than 1-2000 of them?
don't understand the question, but masternodes get awarded a set number of coins from block rewards - not all the block rewards Sorry for my English  I was asking for the possibility in the future that not every user will need the blockchain on his machine. I was asking if it can be implemented in protocol that only masternodes will keep the blockchain. it is possible that not every user stores the whole blockchain. All they need is a "snapshot" (e.g. "one week ago") they trust. So it is up to you if you trust the snapshot-maker enough or if you want to store it yourself. The pools on the other hand should use the whole blockchain to make "legitimate" transactions, and the masternodes as well. The dev has already said I believe that masternodes holding the blockchain is part of the plan. |

two of the main pools knocked out within 24 hrs. Hmmm.
drkpool website ok, no pool
coinmine website down, no pool
Might just be issues preparing for the upcoming fork. There is currently 30GH online, only about 2 GH is p2pool, so there are working pools out there... Recent small price decline is just serious investors shaking the lightweights out. |

Either CPU botnets or large data centers. I saw them once hitting 8.6 GHs of the network. You'd need 500 R9 280x to mine @ 1 GH/s, or ~25000 average botnet CPUs. FPGAs (or even ASICs) are already here. 500 GPUs  I don't think anyone has that much, at least I never heared about something like this. For 1.8 GH/s you would even need 875 GPUs. Nobody here cares about the heavy disadvantage agains FPGAs here? You are all crying about scrypt ASICs but X11 programmed FPGAs are ok?  Show me a working FPGA that's competitive with a GPU and I'll worry. (Or build one ) I know people with ~100 GPU farms, 500+ is not too far-fetched. Assuming it wasn't just a glitch in the reporting software... I'm more concerned about the lack of a startup passphrase in a supposedly privacy focused system. Really, am I alone in this? |

You guys know you can set up as many failovers as you like right?
If you prefer pools to p2p that's fine, but have a p2pool failover (or two) as well, it's better than having your rig idle!

Would it be possible for a government to compromise Darkcoin by building it's own masternodes?
Yes, which is why transactions will be sent through multiple masternodes. As long as at least ONE of the masternodes with which the transaction is routed is not compromised, anonymity is achieved. Eventually we expect that there will be 500-1000 masternodes, so a single agency would have to own 90-95% masternodes to de-anonymize a significant portion of transactions if transactions were routed through 20 nodes for example. Even if that were the case, the number of masternodes the transaction is routed through could just be be increased to 40, 50, or more to thwart their efforts. Plus they would need to drive the price through the ROOF to accumulate a significant portion of the masternodes. Bear in mind too that DarkSend is a useful tool for _EVERYONE_ |

Will there be a new Mac wallet available before the hard fork. What happens if I still use the current wallet after this date?
There would need to be, yes. |

Price is dropping, but someone is definitely accumulating... http://chainz.cryptoid.info/drk/address.dws?188207.htmAddress- XosXcEm3Y6Mv6tmBKd1rUWhqB9Pf1hABj7 It started accumulating darkcoins a week ago and now it already has 192,000 DRK !!! That's a whopping 4.6% of all darkcoins in circulation!!! Wouldn't be Bter would it? most likely Btter Nah the deposits started 4/23. Btter has only been trading a few days. Could be another cryptsy wallet or what about mintpal? Smart trader, or maybe the CIA.  Just picked up another 1100. Current status: SMUG  |

I've been busy. Just looked and woosh so many comments, which is great, but I'm a bit confused about how to proceed. There are a lot of competing views. It's to be expected but makes it a bit hard to get anywhere. I guess I'll go through it again and try to find where the consensus lies.
Just carry on mate, you'll never please everyone, don't worry about it, you're doing a fantastic job. |

trustless
This word confuses most people, they hear it and draw exactly the wrong conclusion. If it's going to be used it needs a few words of explanation along with it. |

Excellent, but first thing that struck me was this:
"Transactions are pooled together in the blockchain" - they're pooled off chain I believe, that's what makes them anonymous?
They are pooled on chain by being pooled off chain first.  All the addresses appear together in one transaction on the blockchain when using DarkSend. Feel free to ignore me then!  |

I've taken in suggestions about images, colours, etc. What do we think of this? http://darkcoinsample.hostoi.com/It would be nice to get a new website up before that wired articles comes out. People will be looking up DRK.  Excellent, but first thing that struck me was this: "Transactions are pooled together in the blockchain" - they're pooled off-chain I believe, that's what makes them anonymous? and "making them anonymous from the wallet." - not sure what this is supposed to mean... "Transactions are pooled off-chain, making them anonymous and untraceable," or something instead? edit: OK "from the wallet" means anonymity built in, no 3rd party stuff required. Some other typos: Download a wallet thingy appears twice in Getting started page Find an Darkcoin exchange should be "a" not "an" You can send Darkcoins to friends, relatives or trading partners "as way" should be "as a way" and maybe lose the plural on Darkcoins to keep things consistent And there are a couple of places with a missing space after a punctuation mark, before the next sentence or the sentence continuing I appreciate it's a work in progress, and it's fantastic work, all the above is meant constructively! edit2: "When making payments with Bitcoin it's like leaving your checking account open in your browser" - eduffield Yeah well so is having the wallet fire up and display all your transactions without needing an initial password. Startup password please, I am going to go on moaning about it, I promise... |
