Well that's not the concern. The concern is an adversary spying on a small but significant portion of masternode activity (say 15%). Your one tx might have an astronomically low probability of being revealed, but other transactions on the network won't be so lucky.


yes they will, that's how probability works Smiley

if there is an unbelievably tiny probability or catching a DS transaction with 15% of the network, you will catch an unbelievably tiny number of transactions....i.e. none in any sensible timeframe.

You will still catch transactions. If you fire a gun into a large crowd, someone will get hit, even if everyone's individual probability is low.

A robust anonymity solution will make it just as costly to unmask one solution vs any other.

OK, let's see. 

(DISCLAIMER: I'm not a mathematician, I just fucked around in a spreadsheet....feel free to rip this to shreds and I will eat humble pie)

If I fire a gun into a crowd the probability of hitting someone is either 1, as you suggest, or very close to 1.

If I compromise 15% of the masternode network (per your example) and, for the sake of argument, everyone is mixing with 4 rounds of Darksend, the probability of tracing a transaction - i.e. having a complete set of data for a transaction is:

1.22265E-66

Let's say there are 1 million transactions in 24 hours, so multiply that figure by 1 million and we get:

0.00000000000000000000000000000000000000000000000000000000000122265

This is how many complete transactions we are likely to sample in one day at 1m tx/day. So divide that into 1 to find out how many days are required to (probably) assemble a complete transaction:

817898000000000000000000000000000000000000000000000000000000

Assuming my calculations are correct (see disclaimer) and I was a betting man, I'd go with firing the gun into a crowd Smiley

Of course this doesn't take into account possible extrapolation techniques that fluffy referred to, but does address your point on probability (probably, again see disclaimer Smiley )









This assumes that one un-compromised round of Darksend is enough.
1702  Alternate cryptocurrencies / Altcoin Discussion / Re: XMR vs DRK on: March 27, 2015, 06:42:14 PM
These probability calculations are misleading because they are from the perspective of the individual transactor as opposed to the attacker.

Evan is basically saying "The networlk isn't secure, but there's so fucking many of you that the chances of your transactions being traced are slim. Here's a really low percentage to distract you: 0.000000000000001%. Wow!"

The probability calculations make the assumption that only one round of Darksend is needed for privacy / fungibility. The correct analysis would entail calculating the probability of say 4 un-compromised Darksend rounds in sequence out of say a 20 round Darksend given that x% of the masternodes are compromised.

Edit:fluffypony hints at this issue in this post. https://bitcointalk.org/index.php?topic=1001642.msg10901590#msg10901590

So?  What is your problem? Big pharma companies buy smaller ones so they could stop the development of current drugs as to eliminate competition.
In this case Evan bought a name. Your developers who sold it are to blame!
Its a free market, you could have bought it off from your developers. Were your developers transparent? Did they tell community what was going to happen?
Your developers saw an oppurtunity to get out with some cash and they did, you guys should do the same as you got the boost!
Also should direct all the hatres towars  your developers who sold the project, your developers abonded your coin! Deal with it !

I rest my case!


Our jugdement is always clouded by our emotional investments

Satoshi made us think in a different way, to not to trust, to question. Satoshi gave us Blockchain, the trustless authority.

When we have blockchain based solutions, why should we place our trust on nodes? Isnt it what we all are here for? to build trustless systems?

There are two types of people here, those who want to gain more fiat and those who want to help humanity. Choose your side
This is a noble sentiment, but not entirely true. There are certainly any number of gradations on the scale running from St. Francis of Assisi, to Bill Gates. Now while I consider BG to be little more than a criminal, on any number of measures he could be considered of more help to humanity than S.t Francis. The fact is that the desire for fiat and to help humanity are not mutually exclusive. More to the point of this discussion is the fact that even a "pure" desire to help humanity will not settle this debate.

I suspect (in a completely unfounded way Wink) that I have more in common with the first person sited above, than most folks on this forum; my pursuit of fiat has been, for the most part, to be able to help others who are not in a position to do so. 10 months ago, on a mountain in the middle of a jungle, connected by a feeble long-distance wi-fi link, I wasted some time browsing, and found an ongoing debate between advocates of something called Shadow coin, Monero, and Darkcoin. As a technophile, and someone who witnessed first-hand the devestation wrought by banksters, I was intrigued.

The vulgarity, and crudeness were hard to stomach, (not to mention the name "Darkcoin") but for the sake of those I wanted to help, I continued investigating. In the end, having only limited resources of time and even less of money, I had to decide to follow only one. In spite of its name I chose Darkcoin. I chose it not based on superior technology, (which I suspected it had) but on the basis of superior people. They had their share of trolls and FUDers, but they also had a reasoned core of supporters (such as majamina here :-) who reasonably and politely stood up to the FUDers and trolls, or simply ignored them. Even more importantly, Darkcoin's developer, did not live in shadows or participate in the trollfest, but continued, day-in, and day-out, to improve the coin. I saw no ongoing development in the other coins, and their developers did not even deserve the term, from what I could see; they certainly weren't willing to show their faces in the light of day.

I returned to the U.S. to teach last September, and began participating in the DRK community, lobbying along with some others for a name change, and slowly trying to acquire a masternode of my own. I now own 908 DASH and hope to buy another $80.00 worth tomorrow. (That is after sending $280 (which is half my pay) to help those I left.") In retrospect  seems clear I have made the right decision. Shadow coin is no longer worth discussing, and the general tenor of Monero backers supports the market's judgment of them.  In large part it was the incessant screams of "instamine," which I was perfectly capable of investigating on my own, which drove me from them. Maybe they are right, and their tech is better, to me it makes no difference, the caliber of their people out-weights any consideration of the tech.

It grieves me to think that most of you probably have no idea what I am talking about, and will never know the joy of being invited to share a meager meal with those who would not be alive but for your small involvement with them. Should you want to experience this, pm me, and I will be happy for you to accompany me on my next trip. It is my hope that it will not be too long before a masternode will relieve me of the need to return to the States to refill my coffers.


If I am wrong, and DASH becomes worth nothing, and Monero takes over the world, I will sleep easy, knowing that Evil men often rule the day while goodness lurks in the dark; that money is but a means to an end, and that character determines the nature of that end.

I pray that you all end well...

These two comments belong together. As BiteMyShinyMetalAss has correctly pointed out the attempt by the Darkcoin foundation to kill Dashcoin in order to obtain the Dash name for the purpose of waging trademark battles in the courts puts Darkcoin aka Dash squarely in the Bill Gates / Big Pharma camp. It also explains the sheer amount of trolling that the Main DRK now Dash thread has attracted after the re brand was announced. This kind of corporate / big business type bullying is likely to rankle many in the crypto coin communities regardless of whether or not they hold Dashcoin or Monero.

strix You have made an impassioned plea for ethics over greed; however its is DRK aka DASH that lies in the "corporate greed" camp.

Isn't Monero empirical proof that scam-free open source crypto projects are still viable?

Absolutely!
It's a gem for this reason if nothing else.
Glad to be around.


Yes it is. it is also one of the reasons I have invested in Monero and support the project.
1705  Alternate cryptocurrencies / Altcoin Discussion / Re: XMR vs DRK on: March 25, 2015, 03:19:15 AM
OK so Dark is bad because my granny with her wallet in masternode is bad because she is a trusted third party...

And I can't use the official Monero wallet with a mouse because the 5 devs trolling here didnt build a GUI yet in the last 12 months, so i should go get a wallet with gui from a trusted 3rd party?

In short, no, that is not equivalent.

You can review or compile the open source wallet yourself, so it is not trusted anything.

so if I want to use a mouse with Monero I need to learn to code and compile first, *before* getting the trusted third party wallet which I then have to review for malicious code.  How long you think the GUI will take then it seems like a bit of a priority and you have a lot of devs around?

This is the Design and Development Goals for Monero. https://getmonero.org/design-goals/ There are quite a few things ahead in the list before the GUI. One can buy now and learn the command line in GNU/Linux and possibly learn to compile code (this may be necessary) or wait until the GUI comes out. Of course the price after the GUI comes out could be higher or lower than now.  Wink

LOL okay by DOS you mean command line, because I was wondering what the hell Linux and Mac users had to do with DOS.

But in any case there is no official GUI. There are five third party GUIs, four of them are open source (the fifth is de facto open source since you can see the source in your browser).

Using open source third party wallets doesn't seem to bother users of Electrum, Multibit, etc. I'm still a little perplexed as to why Monero opponents are so obsessed about it.

His is talking about the Command Prompt in Windows, which does have a fair amount of overlap with the old DOS command prompt.

Nah then bitcoin guys wouldnt touch us with a ten feet pole or how u muricans say that.
Their input is very valuable for us.
You can say that, but history would suggest otherwise. Would you really not utilize a useful product if it had a shady past?

If using slave labor organized by the Nazis didn't hurt Mercedes, then truly anything can be forgiven.

1708  Alternate cryptocurrencies / Altcoin Discussion / Re: XMR vs DRK on: March 25, 2015, 12:38:42 AM
The biggest problem with Monero is that it's being lead by people with zero business sense.

If it were a business your opinion on the matter of our "business sense" might count for something, but it isn't and it isn't trying to be one either. You might reconsider your statement in light of that. I have a pretty good idea you have no clue what you are talking about.
It may not be a literal business, but it's a competitive environment that is similar to running a business. Evan is using his experience with finance and investing to not only create an anonymous payment solution, but to create it in a way that most benefits investors. You guys have this false notion that people care about emission schedules. You have very idealistic notions, and that will hurt Monero in the long run. The world is not ideal, and no one will use Monero just because it's the fairest coin.

Evan understands this, and the instamine actually allowed him to fund development, while you guys have to beg for donations because of your stupid ideals. It's a shame, as I will freely admit that Cryptonote is a more elegant solution than Darksend.

It all depends on the time frame. The focus of the Monero project is to build solid fundamentals and yes this does take time and it is done at the expense of short term results. The "official" GUI is behind a whole list of items designed to build those fundamentals.  Darkcoin is the exact opposite the focus is to deliver results now even at the expense of creating a very shaky foundation. Spork is the perfect example of the need to deliver results now.

Long term Monero is the winner, short term the victory belongs to Darkcoin/Dash. I am in this for the long term so I am betting on Monero.
1709  Alternate cryptocurrencies / Altcoin Discussion / Re: XMR vs DRK on: March 24, 2015, 11:51:31 PM
If the spork key was programmed to last only x number of blocks after a hardfork, like a week or so, would that ease the concerns?

It is a very dangerous precedent and a slippery slope. Of course if one were program the spork key to last for only a week it would mitigate the concerns, but not eliminate them.

Edit: As for FinCEN, I do not know their position on: I am an MSB, but only for a week at a time.

How so? A single individual controls a key that can remotely disable code portions on the entire network. I know of no other cryptocurrency with a remote disruption switch like that.

It is called Spork https://www.darkcoin.io/about/what-is-darkcoin/spork/

Quote
In response to unforeseen issues with the rollout of RC3, the Darkcoin development team created a mechanism by which updated code is released to the network, but not immediately made active (or “enforced”). Communication is sent out to users informing them of the change and the need for them to update their clients. Those who update their clients run the new code, but in the event of errors occurring with that new code, the client’s blocks are not rejected by the network and unintended forks are avoided. Data about the error can then be collected and forwarded to the development team. Once the development team is satisfied with the new code’s stability in the mainnet environment – and once acceptable network consensus is attained – enforcement of the updated code can be activated remotely. Should problems arise, the code can be deactivated in the same manner, without the need for a network-wide rollback or client update. This innovation allows for far smoother transitions than in the traditional hard fork paradigm, as well as the collection of test data in the live network environment. We set out with the intention of calling this method of updating the “Soft Fork”, but the Darkcoin community quickly dubbed it the “Spork” and the name seems to have stuck.

Now here is something really worth discussing. I was starting to get bored with the Darkcoin instamine discussion. To say that this is dangerous is an understatement. This effectively turns a decentralized virtual currency into a centralized virtual currency and the holder(s) of the private keys that control the Spork(s) would very likely need to register as an MSB in the United States and the equivalent in many other countries.

I really don't get this argument. 2300 * 5k = $11.5 million. Woopity friggin doo.
That's a naive calculation. If you want to enter the market now to run 2300 masternodes, you simply cannot obtain 2.3 million coins on the open market. The money required to obtain a sizable fraction of the masternode network is exponentially higher than $11.5 million.

And don't bring the black helicopters into this. By your same 'drop in the bucket' argument, unlimited hashing power can be bought and manufactured. Therefore, Bitcoin mining (or the mining of any other crypto) can be owned by a sufficiently determined nation state. Once they control what's written into the blockchain, it's curtains.

It's patently obvious from history that governments are not keen on relinquishing the power of the purse. I doubt they will build the hashes to pwn Bitcoin, so TPTB will just keep changing the laws to tame the public's interest.



You don't buy the Darkcoins you borrow them.

Can someone explain whether Peter Todd's concerns from the Reddit post a few days ago are valid? What is the plan as far as mixins go?

The plan for mixins was discussed here: https://getmonero.org/2015/02/23/monero-missive-for-the-week-of-2015-02-23.html Could you provide a link to the Reddit post?

i ask u, why all monero fanboys are here for trolling, make a nice GUI wallet and i'll buy ur monero....or maybe the dev team did not have abiity just to make GUI wallet ?

Defending Satoshi in a Bticoin forum is not trolling!

The monero trolls are an embarrassment to crypto. Even the monero devs waste time trolling instead of doing basic things like putting together a official working GUI wallet, So sad.

iCEBREAKER... Your a moron!   Tell you what... Go find Satoshi and bust his balls about premining Bitcoin...

Satoshi never premined/instamined/fastmined/etc. a single Bitcoin.

He publicized his system to essentially 100% of the people in the world who could possibly understand it, worked with a few of them to clean up his code before launch, announced the launch I think a week ahead of time (not sure of the time period, maybe I'm wrong here), and then everyone had years to mine it using ordinary computers before it even had any monetary value whatsoever, with no guarantee it ever would. Of course, the monetary parameters of the system were "set in stone" (his words), were never changed after launch, and the actual mining has turned out to match the schedule stated in the white paper quite closely.

The suggestion of even the slightest similarity between that experience and DRK is ridiculous and insulting, not only to Satoshi but to the intelligence of anyone reading it.

You guys are in good company though, the Bytecoin scammers who ninja-premined 82% of the coins on their system tried the Satoshi Defense too. Right around the time they were claiming that Bytecoin was created by aliens.


Actually defending the good name of Satoshi is a commendable action for any crypto-currency developer worthy of praise rather than criticism. In any event why has Satoshi been dragged into the arguments over the DRK premine?

This may just be the typical weekend pump in anticipation of Monday's news.

Since dark and monero are rising in tandem, it suggest the possibility that this rally may be a reaction to bitcoin fungibility concerns resulting from btc-e blocking evolution stolen bitcoins.

I would agree with this.
1719  Alternate cryptocurrencies / Speculation (Altcoins) / Re: [XMR] Monero Speculation on: March 21, 2015, 03:46:18 AM
Actually we are currently witnessing both XMR/XBT and DRK/XBT rising. So the negative correlation does not hold all the time.
1720  Alternate cryptocurrencies / Speculation (Altcoins) / Re: [XMR] Monero Speculation on: March 21, 2015, 12:25:46 AM
Who was it who was speculating that with a drk price decline that we would see an xmr bump? Now drk seems to be mooning are you speculating that the inverse is true ?


I have made the case that there is a negative correlation between XMR/XBT and DRK/XBT when there are bad news on the DRK/XBT side. The events of March 10 (late March 9 in some time zones) demonstrated this very well. There was a sharp drop in DRK/XBT on strong volume as a result of the initial community reaction to the re-branding at the same time there was rise in XMR/XBT also on strong volume. Furthermore there were not any particularly significant news on the XMR side. What we are  seeing now is a rise in DRK/XBT that has fallen short of the recent February high of 0.01578 on anaemic upside volume accomplished by a small downward sideways moves in XMR/XBT also on low volume.

Is the correlation perfect? Of course not. In fact there are scenarios where both DRK and XMR could rise or fall in unison; however I do believe that significant negative news on the part of DRK/XBT can lead to an unexpected "out of the blue" rise in XMR/XBT. This is due to the much larger 4x market capitalization of DRK when compared to XMR. It is far from clear if the reverse holds true namely good news on the DRK/XBT leading to a fall in XMR/XBT.
