Here to happily reverse troll the monero shills Grin

Just watch how the fag inserted the "BBR is also danger, woo me" and get exposed for being generally a douchebag not just here but in other places. He "holds both XMR and BBR" but is basically a Monero shill. It's not like he is recommending BBR anywhere. You will only find them here to subtly talk down BBR. Just watch how they work.

Edit: Watch for some developments here. drawingthesun is just a fucking rat poision. This is just a small sample. I am not wasting anymore time on it. This community needs to watch out for these fake supporters who come here and say "I own BBR too" and similar lines. They are basically douchebags of the highest order.

I'm quite amazed how weak a hand you are, to be so influenced by people that are not actually on the team of that coin. I and rpietila are not apart of this coin any more that we are "spokespeople" for bitcoin. I am hoping this isn't a FUD campaign just as you start your marketing campaign for BBR

Quote from: drawingthesun on September 02, 2014, 04:38:20 AM

I wouldn't worry about DTM, they belong to a set of users that have picked up dirt cheap mega Boolberry stacks (because they didn't want to pay market rates for Monero) and now are hoping for riches. DTM is never going to stop talking about his Boolberry.

Yeah, GML is also up, but that doesn't mean anything profound.

Do you want us to mention every coin that was up? Only one matters, and it isn't BBR.

Except that Zoidberg is a none trick poney, Linux has expert management skills.

The XMR/BBR sibling rivalry is adorable. Sound like somebody is cranky because BBR spiked up +25% while XMR crashed -13%. Wink

Boolberry spiked because I pissed of James. The joke's on him though, I made so much money from that.

Quote from: drawingthesun on August 31, 2014, 11:30:38 PM

It seems the only thing going for Boolberry is that James is pumping it, James constantly lies about how much better Boolberry is.

As far as I am concerned, Boolberry is now just a pump and dump until CryptoZoidberg dumps James publically.

Dude you need to calm down!

I am not a shill, people know I hold Monero and BBR, I'm not being deceptive about my position.

Also, Monero still does anonymous better than darkcoin, it was a flaw, it was fixed, move on child.

Also, the same attack could have been used against any other cn coin, or did you forget that silly!

Yah unfortunately your post history says you are an exclusive monero shill and a bad one at that. Thank fuck you are not shilling "other CN coins" otherwise they would have started getting pounded like monero too.

What is with pricks coming here and saying they hold BBR and act like the world here owes them something? Seeing more and more Monero shills post this way lately. Is CZ supposed to blow them individually or what is the expectation?

How am I acting like the world owes me something? This is your fantasy, not mine.

Anyway, the BCX attack would affect both bbr and xmr, however I doubt it even exists.

That is your fantasy. Everytime someone attacks XMR you faggots are sure to announce how it is actually a CN issue and how bad CN code is and how sucky it is to inherit a flawed coin bla bla bla. Every other time it is shilling 24x7 about monero.

And then you proceed to post how monero is always hated and attacked. Just keep telling yourself that others cannot see through the bullshit. Anyways we will soon find out who is affected, won't we? Until then Shill Forrest, Shill....

I actually have no idea how to respond to people like you, the problem is that you're inventing a lot of drama in your head that isn't actually real.

You need to take a walk and calm down.

The Anonymint attack, that might only affect Monero, (As Zoidberg said), apparently Tacotime has been working on a fix for some time.

Why make a 500 bitcoin bet, when you can steal that amount instead?

LOL here come the shills. Hero Members and Legendary members defending the gold they found. For those who don't know this faggot is bad news. Anyone remember the Block 21602 attack on Monero couple of weeks ago? This fag was running around with this big mouth in the Darkcoin thread and arguing with the Darkcoin developer and within a day Monero borked.

So the guy who sold celeb photos for bitcoin, he should really have used darkcoin...

Why? Bitcoin is as secure as Darkcoin, if he wanted real anonymity he would have used Monero.

I can't imagine someone with your amount of history would be so ill informed? Darkcoin is quite anonymous. Have you even read how it works? It's my own implementation of coinjoin that is much more anonymous than anything offered on the bitcoin network, plus it's not vulnerable to any of the coinjoin attacks (coinjoin sudoku). It's decentralized, secure, timing-attack resistant and it works on mainnet, right now.

I'm going to just guess that you haven't actually done any reading about Darksend and show you how it works:

http://blog.anonymousbitcoinbook.com/2014/08/visualizing-one-round-of-darkcoins-darksend/

https://bitcointalksearch.org/topic/anndash-dash-dashorg-first-self-funding-self-governing-crypto-currency-421615

Here's an example transaction:

http://test.explorer.darkcoin.fr/tx/6f52d97497c6f6ff2d866de53a1dcd8b3d3b74c8feb16e2e91624fda0985a917

So the gist is if you put 550DRK into the pool, it'll be broken down into 100DRK*5, 10DRK*5 and paired with the same denominations from another user. So after that transaction, no one can tell who is paying for what.

It's also very low bloat compared to monero /bytecoin because it only happens when it's needed. The whole blockchain is 346MB right now. Monero is not even close to as old and already is many times that size.

Isn't the issue here that Dark is an active coin? What I mean is that the user has to actively want to mix their coins and this can create a low anonymity set. (hence the small blockchain)

As I understand it, the Monero chain is larger because every single payment is passively anonymous. (There are exceptions right now due to 0 mixin, but this will be removed soon)

The strength of the anonymity set in Monero is so grand that it makes no sense to use something inferior if you actually need an anonymous currency.

Dude you need to calm down!

The BCX attack, which is pure fantasy. If the BCX attack exists, it'll likely effect BBR too, however I am 99% sure that BCX is being the biggest troll here.

https://bitcointalksearch.org/topic/m.8905825

We are working on resolving this issue. I was the one that offered anonymint a bounty to research BCX's claims. This is a possible exploit that anonymint says has a fix, so as long as we can concentrate on the important things, then it should be just another day in cryptoland.

My understanding of the attack is that it takes a long time to prepare, and it also requires a lot of hardware resources and only can affect some subset of tx. So, there are many conditions and few people will have the ability and resources to pull this off.

Now this could all be an overreaction to some obscure edge case, but when it comes to something like this I do not want to assume it is inconsequential even if it is improbable. At the very least, this provides some intense scrutiny of the algorithms and creates new ways to harden it.

James

I let myself to uncover a little anonymint's research that we was privately discussed this evening: imo it's not critical, it's not about stealing money and it's not coin killer. it's about anonymity that could be compromised on very rare situations(with some specific conditions) and untypical for current transactions distribution(if could call it so). It similar to flaw that i fixed in august ( https://bitcointalksearch.org/topic/m.8548412 ), so this also could be fixed without pain, and as i said - imo it's still not critical.
Anyway, his research was helpful(thanks to anonymint), but it looks like BitcoinEXpress mean something else.

Also many thanks to James for organization efforts!

Anytime there is any possible exploit anywhere near a coin's codebase it is best to do whatever it takes to get to the bottom of the threat. If it turns out to be a false alert, then it is just a few BTC spent. If it is ignored, well, the results could be pretty bad. i think the expression is "better safe than sorry"

BCX's cryptic "implementation" specific phrasing seems to indicate it is specific to XMR and that BBR already fixed this, or at least most of the exposure to this.

In this case, it highlights the thing that we all know for a while. CZ is the leading cryptonote dev, bar none. Now it could be that there are additional vectors to the one that is found so far, so we must always be on the alert. BCX is a serious guy and I have much respect for him. I am glad that both communities are working closely to get through the next 72 hours. Any attack against XMR will not be good for all the cryptonotes, regardless if BBR is already immune or not.

BBR's POW and Diff are different from XMR and the exploit seems to be exploiting XMR only anyway. There is no slippage to BBR yet which is fascinating to me as well as the fact that some of the XMR dumpers also slowly dumped BBR to keep the silver coin in check Wink

BCX's attack has nothing to do with POW per se. It targets Cryptnote's implementation of ring signatures AFAIK.

BBR is a much easier target for a Sybil mediated timewarp attack because it has a far smaller network than XMR securing it.

Please advice Sad

What should be do iCEBREAKER? Are you a professional coder too?

Quote from: TheFascistMind on September 20, 2014, 09:26:59 PM

I am sure everyone knows BBR has a feature which XMR doesn't have yet (and would require hard fork to add), where each coin is flagged with the minimum # of inputs it will mix with when it is transacted in the future. This enables BBR to avoid inadvertent unmasking of the anonymity.

Well when we consider an attacker do that on purpose, then XMR is much more suspectible to anonymity reduction (which we are still trying to decide if also reveals the private key).

We should make popcorn and coffee and order Grubhub chow fun delivery. The next three days will be very interesting. Maybe BBR and XMR will switch market caps? Shocked

This whole story should be converted into a book. Take every shilling, trolling, reverse trolling and reverse shilling and the everything else from the birth of monero into account and how everyone got everything wrong with respect to how good this coin is.

switching marketcaps is a bit much for a single exploit patched and it is quite possible that BCX noticed BBR's fix of this vulnerability and the lack of XMR's fix.

However, the 5:1 price disparity is clearly silly and I expect this to be corrected before yearend

Now this could all be an overreaction to some obscure edge case, but when it comes to something like this I do not want to assume it is inconsequential even if it is improbable. At the very least, this provides some intense scrutiny of the algorithms and creates new ways to harden it.

I let myself to uncover a little anonymint's research that we was privately discussed this evening: imo it's not critical, it's not about stealing money and it's not coin killer. it's about anonymity that could be compromised on very rare situations(with some specific conditions) and untypical for current transactions distribution(if could call it so). It similar to flaw that i fixed in august ( https://bitcointalksearch.org/topic/m.8548412 ), so this also could be fixed without pain, and as i said - imo it's still not critical.
Anyway, his research was helpful(thanks to anonymint), but it looks like BitcoinEXpress mean something else.

Also many thanks to James for organization efforts!

BBR's POW and Diff are different from XMR and the exploit seems to be exploiting XMR only anyway. There is no slippage to BBR yet which is fascinating to me as well as the fact that some of the XMR dumpers also slowly dumped BBR to keep the silver coin in check Wink

BCX's attack has nothing to do with POW per se. It targets Cryptnote's implementation of ring signatures AFAIK.

BBR is a much easier target for a Sybil mediated timewarp attack because it has a far smaller network than XMR securing it.

Please advice Sad

What should be do iCEBREAKER? Are you a professional coder too?

At dinner I suddenly had an epipheny on the exploit. I initially thought I would short Monero, because it seemed it was doomed no matter what I did, because I also see another related attack against Monero because it doesn't have BBR's safety feature. I will detailing this in my next post.

I am sure everyone knows BBR has a feature which XMR doesn't have yet (and would require hard fork to add), where each coin is flagged with the minimum # of inputs it will mix with when it is transacted in the future. This enables BBR to avoid inadvertent unmasking of the anonymity.

Well when we consider an attacker do that on purpose, then XMR is much more suspectible to anonymity reduction (which we are still trying to decide if also reveals the private key).
