The Future Of Work
Just curious as to what is going on with anonymity testing / bug fixing. I know there was the test Wednesday and it seemed to work well - what is the plan going forward?

Do you have any milestones scheduled?



Except for cleaning up some minor bugs, he just has to put some protections in.  He posted about them early this morning, I asked if he could use at least 3 of the systems he mentioned to double up on securing the transactions from manipulation, and he said that's probably what he'll end up doing (couple of pages back)


Every clones and even the well established coins would add the darksend tech to theirs . .
Will this anyways affect the growth potential of DRK???


it isn't so easy to do, and when they do, we will already have been using it.  There is something to be said for being the first.  It's been established that we must keep it open source or nobody would use it.

Thank you, I get it.

I got my miner compiled, now it's all about configuration I assume.
My 3 cards are full of Hardware errors, I'll investigate.

Thanks for your help.

I tryed to do something like that, even modified my gpumon to make screen-r point to sgminer, samething with tha common.pl file to link the "mine start" command to sgminer.

When I launch mine start: i got the Gpu(overclock line, then nothing more. the process crash. I don't know what the problem is. I'm very bad with that linux stuff. I was thinking may be it's because of my cgminer.conf file. I put kernel : darkcoin and darkcoin: true inside it. Is there some sort of log file to know what the problem is?

I don't know if you saw the updated post, so  here it is again.  It's for the GPU miner.

First, update your driver to latest stable release
Then download and install the AMD_APP_SDK

Now download the ADL_SDK, hang on to that


do an apt-get update

then   apt-get install -y build-essential m4 libssl-dev libdb++-dev libboost-all-dev libminiupnpc-dev git automake libcurl4-openssl-dev

now download the source;

sudo git clone https://github.com/evan82/darkcoin-sgminer

go into that folder, find the ADl_SDK folder and copy the contents of the ADL_SDK folder you downloaded and unzipped earlier into this folder

cd darkcoin-sgminer

./autoconf -i
  
./configure CFLAGS="-O3 -march=native"

make


just chnge the "darkcoin-sgminer" and /evan82/darkcoin-sgminer to whatever version you're doing  Hope I covered it correctly, good luck

We need to get on cryptsy. The market manipulation is just ridiculous at this point.

Hello,

I've got a question for buying BTC.
As I think it's low, I was thinking in buying BTC with $.

But what I saw in coinbase : Bank Accounts Used to buy and sell bitcoins — U.S. only
Can't use visa credit card there?

I already try the VirWox.. They closed/banned my account directly because I was suspicious lol.. They never told me why, the country?

What?Huh For information I'm French living in Mexico.

How can I do to buy BTC with fiat? I never did it, always haing BTC by mining other coin....

If you do have credit card, i can refer a good merchant.

Who else takes CC?

Sorry . . They stopped accepting .

I'm posting this here, for everyone's benefit. Thanks!

Hi, I am Gnosis, the Anoncoin developer working on implementing Zerocoin. First of all, I think it is excellent that there is so much interest in developing a fully anonymous currency. I am not just a developer but also a user, or I will be when an anonymous currency exists! When coin creators compete, the coin users win!
However, CoinJoin has been around for a while, and it has not seen much use for anonymity. There's a good reason for that: it's not very anonymous.
Quoting my bitcointalk post:
Quote
CoinJoin has questionable anonymity compared to Zerocoin. The reason is that with CoinJoin, two or more users must somehow partner up and forge a transaction together. They communicate over a secure channel to do this. The coins are only mixed among these "partners." Picking partners you can trust is a significant obstacle: how can you know that your partners will "forget" the mixing that happened? One may try to repeat this 10 times with randomly chosen partners, but how can you know that your partners are not all just sock puppets of one malicious entity (on an anonymous network, it is trivial to create as many fake users as you want )? If that is the case, then your efforts are in vain.
Compare this with Zerocoin, where you put your coins in an accumulator, and they are mixed with the coins of all users who have put coins into that accumulator, since the beginning of Zerocoin. There would be a different accumulator for different denominations of Anoncoins (1, 5, 10, 50 ANC, etc.).
To put it simply, the more users' coins your coins are mixed with, the more anonymity you have.
I cannot speak to Darkcoin's implementation (or planned implementation) of CoinJoin since I cannot seem to find any specs or code on their Github or their site. If anyone knows, please point me to them.
I look forward to a practical and secure solution for anonymity from the DarkCoin devs! Smiley

First off, these are fantastic questions. The answer to implementing this in such a way where it is very difficulty to exploit is by adding cost and verification.

Here’s the gist of how I envision DarkSend to work in the long run. Some of what I’m going to mention is done, some of it I’m working on currently. I’d love some ideas on possible attack vectors on my implementation, so we can make it as bulletproof as possible.

Pools

DarkSend adds various extensions to the Bitcoin protocol for implementing transaction pooling. Like normal Coinjoin the pools take transactions in stages. The stages currently are:

POOL_STATUS_IDLE
POOL_STATUS_ACCEPTING_INPUTS
POOL_STATUS_ACCEPTING_OUTPUTS
POOL_STATUS_SIGNING
POOL_STATUS_TRANSMISSION

So the users relay these items throughout the network as the stages happen. After all items are gathered into the pool, the transactions are merged together into one, remotely signed and then broadcasted.

Masters

To defeat propagation problems, master nodes are elected each new block. They are responsible for being the authority of what goes into the joined transaction each session. This is done in a tamperproof way, but I think it’s not important to the discussion.

So what is the cost?

There must be a cost to using this anonymous network, otherwise like you say there will be issues with millions of accounts popping up. I’m not dead set on which solution(s) to implement, but here’s a couple ideas:

Burnt Identities

Higher difficulty shares to the current block would be mined and then stored in the blockchain permanently. Multiple of these would be used for each transaction and would be “burnt” when misused, causing the attacker to have to mine them again.  

Verification?

To use the pools it will require unique unspend outputs, someone that wants to mess with the system would have to have a large pool of funds in many addresses. So to attack a pool with 100 slots, you would require funds dispersed to 99 addresses, on 99 nodes working in common.

Other possible fee-less solutions?

There is interesting research on protecting against sybil attacks that lends itself really well to a decentralized ledger, such as this paper:

http://dimacs.rutgers.edu/Workshops/InformationSecurity/slides/gamesandreputation.pdf

The idea is to build a social graph of the inputs and outputs of each entry and they should all know different people. If 99 of them all have the same “friends” that they associate with, then they’ll have to enter a different pool. Which will ensure the pool is not full of the nodes belonging to the attacker.

An application for machine learning?

I’m been making models for trading equities for over 7 years now. I ran a financial firm that sold the signals for a few years and I have experience with natural language processing using classifiers. So, I could make a classifier and actually embed it into Darkcoin to determine which pool a node should use, to separate out nodes that seem to be in common.

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.

I’ve been working on DarkSend about a month and we’ve already fixed the decentralization and propagation issues, this is just another bridge to cross in the future.

Thanks!

Is it possible to implement 3 solutions to work side by side?  Or would that conflict or slow things down too  much??  I like repetition Smiley

I think that's what the end result will be and it shouldn't slow down anything

Then that is what I would do Smiley

Hello,

I've got a question for buying BTC.
As I think it's low, I was thinking in buying BTC with $.

But what I saw in coinbase : Bank Accounts Used to buy and sell bitcoins — U.S. only
Can't use visa credit card there?

I already try the VirWox.. They closed/banned my account directly because I was suspicious lol.. They never told me why, the country?

What?Huh For information I'm French living in Mexico.

How can I do to buy BTC with fiat? I never did it, always haing BTC by mining other coin....

If you do have credit card, i can refer a good merchant.

Who else takes CC?

Every clones and even the well established coins would add the darksend tech to theirs . .
Will this anyways affect the growth potential of DRK???
It is all about the community and future development.  If we come together as a community and eduffied and hopefully future developers continue to improve Darkcoin, then we're golden.  If the community is only in it for short term profit and eduffield and other devs don't feel like making improvements, then we're in trouble.

So, what accordingly would be the expectations from the community?

Hmm.
What normal hashrate for 280x, 270x and 7850?
On 280x i have 1.8mh
270x - 1.176mh
7850 - 1.050mh

Its normal?

on my 280x i get 2.18 mhash

it's a hardware thing!
Consumes more energy than scrypt or no?

Users report it consumes about half
My gpus are taking 1200W with DRK and 1500W simple scrypt

The guy with the killawatt reported a 38% difference.

That's right my power usage mining Darkcoin is 38% less then mining lets sat Doge.
