Nice.

Now just to get on Mintpal, the big one.

The fact we've had 1000BTC days on a smaller exchange like Poloniex is very encouraging. God knows what will happen when we get on Mintpal.

I am amazed at the amount of trolls on here...this is literally unbelievable...miserable pricks...

Trolls: Fuck you pricks, I am harvesting your tears like fucking rainwater and drinking them in my top fucking shelf margaritas hahahaha CRY CRY CRY PLEASE i love it =))) Every time you guys cry I feel sooo good hahaha

LOL

yeah that was a good post lol  Cheesy Tongue

Indeed. Gave me a good chuckle.

Guys, do we have any progress on getting listed on Mintpal? I know obviously we are cryptonote technology, which has different api's to Bitcoin but I think it would do wonders for our adoption if we could get on there.

I honestly think we could go up 300% if we got listed on Mintpal. Sadly I don't even see us on the list of coins to be voted in.

stop replying to coinpredator(return) he is the last of the trolls left from the previous thread, just ignore him

+1.

Instead let's focus on this:

24 HR LOW - 0.00014800
24 HR HIGH - 0.00029550  
LAST PRICE - 0.00027199  

which happened after the market reacted favourably to some great things to come: http://www.reddit.com/r/blackcoin/comments/26bojv/big_news_blackcoin_new_developments/

So much good news. So much to look forward too. And with the Max Borges, the top tech PR firm to guide us, I see us getting a lot of high profile press. Especially with so much INNOVATION.

This level of greed and hysteria is always a sign you're in a bubble. Reminds me of some of Bitcoin's bubbles.

The drop down from here is going to be sharp and very quick. Rises like this are never sustainable.

"Hello everyone, I am here to announce current developments within BlackCoin

1) New PoS 2.0 System by rat4 The main man, rat4 himself, has been working hard and diligently on what we dubbed "PoS 2.0". This new Proof of Stake system will further solve potential attacks to vectors that other currencies are vulnerable to.

2) We are currently working on a new privately developed BlackCoin wallet. This wallet will introduced an exclusive anon and multi signature feature. Also along with that some More features that are yet to be announced but will be Revolutionary. The wallet is Code named "Legionaire".

3) Dzimbeck, an external developer, is working on a system that will bring smart contracts, decentralized cash/btc/blk markets, anti-malleability and other features.
4) We are now in conversations with a national sales team leader that worked for a very large visa/mastercard point of sale company. He will lead our national introduction to merchants on accepting Blackcoin through Coinkite and through a yet to be announced blackcoin wallet system.

5) It’s about one week until Coinkite will add BLK to their PoS systems. For those that do not understand the importance of this, this will make BlackCoin available in the real world. People will be able to buy BlackCoin directly from the terminals and also buy products directly from shops. In my opinion Coinkite is one of the most important companies in the crypto space right now.
We will be answering questions this sunday on our live BlackCast.
If you have any questions for us please feel free to leave your questions below.
I will See you all on Sunday :-) UBER UBER

The dev of Darkcoin implemented a Much much more advanced CoinJoin than maxwell did.. You cannot compare the two. The darksend/masternode system is as anonymous as Ring Signatues.


The Darkcoin dev himself says Ring Signatures are more anonymous. Which is why he wanted to implement them in Darkcoin.

His words were pretty much, he will be implementing ring signatures, which will substantially improve anonymity.

It's pretty sad you bash MRO every day in here. You make yourself look quite the embarassment. Would you like us to post in your topic constantly bashing Darkcoin's weaknesses?
1151  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][XCO] XCoin | New Secure Hashing Algorithm (cpu only) on: May 22, 2014, 08:34:22 PM
So, HUGE progress this morning! I have a proof-of-concept of the anonymous transactions working on testnet! Here's some screenshots, these were 3 separate transactions sent to 3 different addresses, at separate times.

Notice how you can't tell who is sending to who. Soon all blocks will only have 2 transactions, 1 for the creation event and a merged transaction with everything else.

http://www.xcoin.co/coinjoin1.png
http://www.xcoin.co/coinjoin2.png

That's so cool you got it working, but could you explain to those of us that aren't knowledgeable what it all means please?  I understand how it's supposed to work, I just don't understand how to read the chart,  Cheesy  Tongue

I also feel that if you were to explain it, there would be great interest from the public!  Thanks!

Bitcoin is often promoted as being somewhat anonymous, but the main problem is that if I know your address, I can literally tell everyone you've ever paid. Imagine everyone you met, was able to see everything you bought in your checking account. That's pretty much the situation Bitcoin and other alt-coins are currently in. We need to move quickly to a anonymity-by-default approach.

There are many solutions out there for fixing this and we know how to implement them. But, the developers are very scared of implementing these fixes, with the possibility of bringing down a 10+ billion dollar economy.  So it will take years at the very minimum to do this.

So, that's where XCoin comes into play. I want solve many of these problems that Bitcoin and other alt-coins experience, making XCoin the beta to Bitcoin. The goal is to be years ahead in development, with cutting edge features that would be insanely difficult to pull off in their codebase.

So what progress was made this morning? I implemented a rough version of CoinJoin. The idea behind what I'm working on was originally put forward by Gregory Maxwell  and it's a great idea (if you want to read more, the original post is here: https://bitcointalk.org/index.php?topic=279249.0).

In short, transactions in the Bitcoin Blockchain are stored like this:

"User1 paid User12 the amount 1.2BTC"
"User4 paid User2 the amount 1.2BTC"
"User11 paid User3 the amount 1.2BTC"

In XCoin they'll look like this:

"Debit User1 the amount 1.2XCO, Debit User4 the amount 1.2XCO, Debit User11 the amount 1.2XCO"
and
"Credit User12 the amount 1.2XCO, Credit User2 the amount 1.2XCO, Credit User3 the amount 1.2XCO"

Notice, in the XCoin you can't tell who paid who. But in Bitcoin the parties are linked together. This will be a large step forward to providing anonymity by default.

It appears the technical design of this DarkCoin is fundamentally flawed and can't be fixed.

There must be some proof that senders sent transactions for all peers on the network to verify before they can accept the block and begin working on the next block solution. Such proof must exist otherwise balances could be stolen by rogue peers.

Thus I must assume you are doing a CoinJoin-like proof for all senders that in that block. And I assume these proofs are transmitted with the block, even if you purge them later (using a proof-of-work chain such as in the mini block chain design).

The problem is that CoinJoin is subject to denial-of-service attack in that if any sender fails to sign in the second step, then no senders can send.

Thus CoinJoin can't scale to a larger number of senders joined. It works best with a few senders and the probability of denial-of-service (rogue sender) is low.

Did you even read the CoinJoin thread carefully?

There is a second insoluble flaw that CoinJoin does nothing to obscure IP address and thus you have no anonymity against powerful entities.

P.S. I don't have time to read 300 pages of this thread to find out if you already addressed this issue. Please give me a link to any prior reply.

Wow, it's that open eh?

Still, this example implies that one could still link up the amounts of the transactions to find the end users.  How unique are transaction amounts, and how hard would it be to hide that level?  Is there a breaking up of the payment so that the amounts are harder to compare or something?  Or am I missing something due to the simplification of the explanation?  

Yes, you could still use the transaction amounts to track money through the system. This combined with some logic to use common transaction amounts or some other logic like that in the wallet could definitely help. Even with the problems, having coinjoin implemented directly into the client is a huge step in the right direction.

And timing analysis too.

^ are these points still valid?

When is the darksend code being open sourced so it can be vetted by peers?

the old thread should be reopened

With self moderation added imo. If the board won't allow it, maybe emailing a moderator could get it done for us in the back end.

That thread gets a lot of hits on google still and is top of my search results when I google for blackcoin on bitcointalk.

Yeah, not for anyone, but self moderation has been keeping this thread in order. The only two thinks we can do at this point is making sure this one grows big enough or get the old one self moderated / a link to the new one.

Just keep posting here Smiley We'll outgrow the old one soon enough!

Yeah. Maybe rat4 can shoot a quick pm to the moderator and ask for it to be made self moderated.

That said, the old topic was probably the most trolled topic in bitcointalk history Cool So I don't mind forgetting about it and just getting this topic up to 1000 pages.

Bytecoin will also have to fix it's own issues to become NSA-proof. As it is right now, it is not. And the extremely low transaction volume in its network doesn't allow for much mixing (same applies for clones). Mixing without volume = problem. Darkcoin has a tremendous advantage in that department.

I'm afraid with that, you show you have no clue what ring signatures even are. This is actually where CryptoNote outperforms DRK by a massive margin that cannot be closed. DRK, like just about all altcoins, has a microscopic volume in the bigger financial picture - only BTC (and maybe LTC) has the consistent volume to pull off half-usable CoinJoin since it requires other participants. Ring signatures do perfect mixing with arbitrary amounts and arbitrarily low volume. And I do mean perfect. They are the theoretical limit that CoinJoin can't approach. ZKP is also perfect, but with a larger anonymity set that comes with other costs.

You also don't seem to understand 'bloating'. Because that's actually not even it - the issue is pruning. All cryptographically strong anonymity solutions cannot perform pruning because they, by nature, need outputs from far in the past. Why? Because that's precisely how you get a large anonymity set! The very reason Bitcoin and Bitcoin-clones like DRK can perform pruning is because their anonymity is of low quality and fundamentally limited to that low quality. Saying a system has '99.99% anonymity' when you don't seem to understand the concept of an anonymity set is kinda of silly, no?

There actually are (inconvenient) ways to prune ring signature or zero knowledge currencies.
But here we are in 2014 with a large Bitcoin blockchain and we're doing fine. Hardware and network improvements have outpaced the blockchain growth. If sync time is your argument against actual anonymity rather than pretend anonymity, that's rather unconvincing.

Very nice post sir.

How did you gain this deep knowledge of the protocols? If you are a coin dev if it would be great to have you on board this project.
1155  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][SYNC]X11 | POS| 1,000 Coins| 1 day mining left| NOW ON MINTPAL on: May 22, 2014, 07:31:26 PM
I dumped this coin yesterday for 40% profit as soon as it became clear the encrypted addresses only apply to the web block explorer.

I'll wait until there is something working as a lot of coins are promising anonymous but only DRK, MRO AND BCN have it working.



In the long run do you think DRK will be the winner?  MRO is the only other one worth considaring. 

DRK is massively premined (something like 20 to 30% of all the coins mined in the first day according to the block explorer). Darksend is also closed source and thus not reviewed by peers. The market cap is now also pretty enormous... each 100% increase in price costs a fortune now. Plus the protocol is not fully anonymous and they are looking to incorporate MRO's ring signatures instead (DRK dev admitted he's working on it).

MRO on the other hand is not premined. The supply curve is a straight line starting from zero as you can see here: http://monerochain.info/charts/coins There's also less than a million coins in circulation. And the market cap is 25 times smaller than DRK.

Since there's virtually no coins out right now that are anonymous and DRK has grown to a massive market cap, it seems logical that any other coin that offers anonymity features is underpriced. Hence the rush of new coins such as SYNC, XLB, XC, promising anonymity features being worked on.

I don't know if MRO will be a winner, but I do strongly believe it's undervalued.
1156  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][MRO] Monero - Anonymous Currency Based on Ring Signatures on: May 22, 2014, 07:06:33 PM


thats all you need to know about DRK.

Is that really true?

No wonder the guy behind it is supporting it like it's his full time job.

Buy and sell your MRO at https://cryptonote.exchange.to

Don't use Poloniex. Had several withdrawal issues, site constantly fails to load...
1158  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] BlackCoin (BC/BLK) | PoS | No Premine - No IPO - ONLY OFFICIAL THREAD on: May 22, 2014, 06:31:57 PM
- Basically what BlackCoin needs is a coinbase like service but just for Blackcoin. So your average joe in the street can easily buy a small amount of them and store them in that service online. So they don't need to worry with the hassle of downloading blackcoin qt and the blockchain etc. This should be a trustless service.

- We can then market this service in conjunction with the PR campaign.

-
A bonus would be having a dev working on some anonymity feature.

^ What I describe is a dream scenario. With those three things combined the price would go up x10.
This is short therm thinking good but short therm.

Serious people to attract serious investors have goal and plan.
We as community can eg. vote in foundation on direction of BC which will promote in BC foundation.
1. GIVE BC GOAL why because when you don't know where you are going you will never go anywhere.
Main goal of BC my eg.:
1st digital currency which is easy in use and works perfect as store of wealth.
...
2. Plan road map which goeal can bring you to your goal faster.
3. Go to goeal till you achive it fix mistakes and go to goal.
Now you filter your ideas with goals:
- anonymity feature - is not best for as our main goals
BIG future investors could be deter by it so why go that way when you can
lose more in future because of present greed ?
Because you can get +20% in next week and loose 99% in one year when governments will hunt
business supporting anonymity...
Personaly i don't want anonymity at BC this is not suits our goal try think in more than month period you you see more dark traps than overall +.

My first two points are the main ones. The last point of anonymity feature is just a bonus. Regarding anonymity, it will be coming to Bitcoin sooner or later anyway so I don't view it as a dangerous thing to have. However it's not a top priority.

Our number one goal, in my opinion, is to make a service which allows anyone to buy BC quick, easy and safely. Just like coinbase. Every new person who buys BlackCoin is another person who is on our side and will spread the word.

Your post shows how misinformed/ignorant you are.

Masternodes are an ingenius idea.

They serve to anonymous transactions
They serve as an incentive to uphold the network

Monero only has Ring Signatures going for it, which has terrible issues such as bloating and scaling, not to mention that anyone and his grandma can made a Bytecoin fork, like the devs of Monero did.

17 posts made by you in this topic in the last 24 hours, all bashing Monero and trying to spread fud  Cheesy

Have much of an agenda?
1160  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][MRO] Monero - Anonymous Currency Based on Ring Signatures on: May 22, 2014, 06:09:46 PM
I told Evan to reconsider the use of ring signature due to their scaling / bloat issue a bit prior to his post: https://bitcointalk.org/index.php?topic=421615.msg6862900#msg6862900

If he can do it without ring signatures+bloat, we're great.

What we are actually discussing right now is this:

99.99% of transactions are already private/anonymous to all but a bad actor that has access to all the network. Otherwise if someone sees a DarkSend they don't know who sent what to who. (provided they'll also have IP obfuscation / TOR etc)

So, we are not talking about achieving privacy or anonymity right now. We're trying to be NSA-proof, or close to that so that the theoretical event of someone knowing what goes on is eradicated. As far as I understand, Evan has an idea on how to improve the way masternodes conduct their transactions so that even the nodes don't know what they are transacting. When that happens, even controlling all the nodes will be futile as an attack vector and almost total anonymity can be achieved - at least as far as coin mixing goes (Bytecoin is also coin-mixing, Zerocoin is in another league but has other drawbacks).

Masternodes are such a blatantly broken idea I cannot imagine someone encourages it in good faith. How do masternodes/miners/whoever verify if a coin is not double spent and originates from a wallet with sufficient balance if they don't know what they are transacting? There are three options:

1. Zero-knowledge proofs, but that is Zerocoin at the moment and the drawbacks are catastrophic.
2. Ring signatures and similar constructs that hide the sender in a subset of the network.
3. Some other information leak that is not documented.

Do you understand why there is no other way?

If the New and Improved DRK implements 2, then it has at most the same strength as MRO and possibly less, with the added bonus(?) of more, unnecessary centralization. If it implements 3, then it is a failed anonymity solution.

+1.

Darksend also needs to be open sourced asap so it can be thoroughly vetted.
