921  Alternate cryptocurrencies / Altcoin Discussion / Re: Can anyone explain me the exact reasons for the hate on Monero? on: September 19, 2014, 06:54:23 PM
I appreciate your honestly.  The reality of the situation is that it appears that this is a hype type situation around a technology that are going to lose a lot of small fishes a lot of money.  By continuing to hype what WILL come crashing down (if not in price first - then by the exploit BCX outlined if it stays a decent sized target).

I honestly don't see this "hype" situation you're describing. We don't make promises or say we're going to do something merely to create hype. When we push something out, like with the OpenAlias system we pushed out today, we are already well down the road to having it working, if not completed already. Anyone outside of the core team that tries to create hype will have to, unfortunately, deal with out release cycle.

We (the core team) have already stated that we will work on Monero regardless of whether the price goes up or down. Monero is not going to "die", even if the price goes down. The exploit still has more vague hand-waving than actual details. Nonetheless, if such an exploit exists then either we will figure it out over time and patch it, or the exploit will be used and we will patch it (just as we did with the block 202612 exploit).

This, too, will not make Monero "die" any more than Bitcoin "died" in August 2010 when someone created a block with 184 billion Bitcoins. They had to suspend the network and roll it back, causing a fork at that bad block. It took over 2 days for the correct fork to win out. In fact, Bitcoin has, over its history, had 23 exploits serious enough to have CVE numbers. And yet it hasn't died. This constant declaration of death because someone manipulates the price or some other person unverifiably claims to "have an exploit" is just silly.

The entire thing is built around greed of the big guys (see rptellia). 

The "big guys" were not around at the beginning, so I can't get how you say that "the entire thing is built around" them. That makes no logical sense whatsoever. Either way, they can be as greedy as they want, they're not affecting us or our ability to develop. Eventually their "greed" will either result in them being rewarded financially, or they will chicken out and leave. Not every early, loud-mouthed Bitcoin proponent is still around.

This overt stab at screwing people over and being dis honest by creating hype about a technology that is NOT ready for prime time has created this backlash.

Again, where is the hype?

Are there proponents of Monero who say that Monero is "amazing" or what have you? Sure. But I have not seen them claim Monero is ready for prime time (in fact, quite the opposite), and I have not seen them claim we're developing anything that we aren't.

@fluffy, awesome intro on the openalias project.

Can you please check if I've configured an XMR alias correctly at the following DNS location:
myagui.monujo.com

It's not a secured domain or anything at this time, I just wanted to check if I got the implementation basics right.
Thanks!

Someone needs to check the source code too but I believe the whitepaper's notation is screwed up.

The paper defines private key a and public Key A through the transformation A = a*G, where G is the Hash function.
So in this case, the multiplication step is to denote the hash mapping.

In the paper, it also defined the key image as I = x * Hp(P)

Now this seems like it is the multiplication of private key x with the hash to the public key P.

But I think this is actually I = x * Hp(P) = x*G2, where G2 like above is another hash function so this is just a hash of private key x using some deterministic hash function that is dependent on public key P (Hp(P)).

I'll just quote from someone who knows way more math than I do -


sarang: The operation is actually repeated elliptic addition... and that addition is really a curve intersection and some other complicated shit
sarang: Multiplying an integer by an elliptic curve point is well-defined
sarang: the x*H(p) is not another hash
sarang: You convert the hash output H(p) to an elliptic point
sarang: and then do the integer-elliptic multiplication
sarang: so it's super important to identify what is an integer and what is an elliptic curve point
sarang: The notation is identical, as it would be in formal mathematics
sarang: They usually use lowercase for integers and uppercase for points
sarang: and always use the multiplication order integer*point
sarang: just as a matter of convention, that is
sarang: so anyone saying you can divide a point by an integer is wrong
sarang: elliptic curve crypto would be broken wide open if that were the case
sarang: Oh, and G is NOT a hash function. It's the elliptic base point
sarang: so A is also an elliptic point

I'll apply Hp on all public keys (P is public key) in signature.
I know I, P, Hp(P) seems I can compute x

x = I / Hp(P)
 

Edit:
P is one of 6 public keys ... I'll try all

lol cryptography, how does it work?

https://cryptonote.org/whitepaper.pdf
Quote
The signer picks a random secret key and computes the corresponding
public key P=xG. Additionally he computes another public key
I=xHp(P) which we will call the "key image"
...
Nobody can recover the public key from the key image and identify the signer

lol, but everybody can compute "key image" from public key and then identify the signer


Edit
if this mean I = x * Hp(P) then I can compute even x

x = I / Hp(P)
I is known  and I can compute all Hp(Px)
 

Hp is a deterministic hash function. You only know I, x is secret. P is computed using x. Explain again how you're going to reverse the hash function?

Ok I'm not sure about "image key". I red somewhere it is derived from private key (so only me can verify because only I know private ) ... But in this paper "image key" is derived from pubic key. Does it mean I can use  VER to find out who is really spending ?

This is a TA thread - if you're struggling to grasp the cryptography then you are welcome to continue this discussion in the Monero ANN thread: https://bitcointalk.org/index.php?topic=583449.0

Alternatively, if you believe you've found an exploit, I do encourage you (again) to document it and write a PoC like every other security researcher. The process of writing a PoC normally forces me to come to grips with the intricacies of the subject, and I document thereafter.

Rem tene verba sequentur, as they used to say.
929  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: September 18, 2014, 01:00:47 PM
Got no problem with an optional payout (and even setting it to non-zero as default in the official client).

The proposal I reacted to made no mention of it being a setting, i.e. optional, however.

Ah ok, so just to make sure everyone's on the same page, this is the screenshot from the Missive:



The idea was to make it "ticked" by default, and it's a per-wallet setting, but if people want to disable it or increase/decrease the percentage they can at any time. Before the GUI is even released, though, we wanted to add this in to simplewallet / rpcwallet - again, prompted during wallet creation, and configurable at any time.

Now I know this seems like a small amount, and it won't do much difference, and you're right. This is not going to satisfy the immediate and large funding requirements. Which is why this is more of a longer-term thing to make sure we always have budget for ongoing efforts / maintenance. It does not preclude fundraising for specific features / tasks.
930  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: September 18, 2014, 10:25:38 AM
Okay, to stay on the topic. I'm community as you rightly noted and I'm a miner and I think that's a great idea. To split (or tax or whatever) block reward to finance development or whatever the said community deems necessary. If only the proceeds would go to some special address and can be spent by some voting system hardcoded in the client (and some special transaction put in the blockchain). Something akin multisig only for all coin holders . If community can't decide on what she wants money is unspent, no harm done.

Edit grammar

The problem is that in these early stages we (as in the core team) need to take the role of "benevolent dictator". The reason is that "design by consensus" has never worked - invariably someone or some group will be able to swing the vote in favour of what "they" want. By having a "benevolent dictator" that the community trusts will act in the best interested of the cryptocurrency (and not in the best interests of individuals with voting / buying power), AND who will revert a change / proposition if there is sufficient kickback, you allow for a more unified vision to be realised.

As a core team we have a pretty concrete vision, but it's hard to put it down on paper and look ahead when we're scrabbling to fix urgent things right now.

What I think would work is for us to raise funding to sort out the short-term urgent issues, and then longer-term we can raise funds for specific features / aspects.

I downloaded the newest version and it is no longer detected as a trojan. (it is incredibly slow though Tongue)

Slow compared to 0.8.8.3? What part of it is slow, what operating system?
932  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: September 17, 2014, 06:56:25 PM
who is on damage control  Undecided

What damage? Should we react every time someone claims something? At this stage, given that there are no technical details, we can only assume that it may be true or it may be false. And, thus, do nothing until something tips the evidence either way.
933  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: September 17, 2014, 05:53:59 PM
Hahem am I the only one that think BCX's findings are worrisome?

Claiming to have something and providing evidence thereof are two different things.

If you have an exploit for a (genuine, not-scammy) FOSS project, not releasing it *at least* to the developers is unconscionable - you aren't hurting a corporation or a bunch of fat cats, you're hurting a small group of developers who work - unpaid - on a software development project for the presumed betterment of everyone. You're hurting altruists who are giving of themselves for little or no reward, but I guess there are people who are so ethically imbalanced that they don't even consider this.

At a minimum some technical details about it would be nice.
934  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: September 17, 2014, 04:37:26 PM
Also obviously this would have to be temporary. The devs would need to commit to weaning off of such a system after given features are implemented or a given period of time.

I would suggest exhausting all possible external options for raising funds before building something into the software. I think going this other route would be more scandalized and trolled than you're considering.

I don't think that it's fundamentally bad to build something into the software. Not sure if you saw the Missive, but in the last wizard screenshot there's an idea for an auto-donation system we want to implement: https://i.imgur.com/ACDmOFJ.jpg

The basic idea is that it's completely user-selectable, based on a % of your tx fee (cumulative to avoid adding dust outputs) that is added on top of the tx fee, so it'll never have a major impact. In the GUI we'd most likely have it on at 50% by default.
935  Economy / Speculation / Re: rpietila Wall Observer - the Quality TA Thread ;) on: September 17, 2014, 04:29:19 PM
I do not talk about bitcoin here. Bitcoin is signing transaction perfect. It does not use ring signatures.

Edit:
Alice, Bob and Carol do not want spend their Monero. But hacker Dave wants their money. A ring signature obscures identities because it only proves that a Dave belongs to a group. So Dave ring-signing Alice, Bob Carol and Dave inputs and send XMR to his new stealth addresses.

Edit2:
Monero is same as money on the pavement. So easy to just pick up them from the pavement. Easy money ... but worthless, who can use them?
(Am I wrong ? Why ?)

You're right. What you've pointed out is clearly a gaping hole that allows an attacker to just take everyone's money, and somehow myself, tacotime, smooth, the rest of the Monero core team, andytoshi, gmaxwell, Wladimir v d Laan, Peter Todd, the Monero Research Lab mathematicians / cryptographers, and everyone else that has read the whitepaper and/or looked at the implementation missed this obvious and gaping flaw. Clearly you have the superior intellect and knowledge, I look forward to seeing your published research and PoC code for this flaw soon.

Until then, have a good day.
936  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: September 17, 2014, 02:54:33 PM
I did notice adding up all the XMR donations in the thread rptellia created was quite a bit more than 25 BTC (more like 40?) so I guess you must've exchanged them at lower rates to pay for expenses?

Yes - rates are at-the-time that the expense needs to be paid, so obviously donations took a beating when the exchange rate was quite a bit lower.

I think it would be a great PR move to somehow make how much "in the hole" the project is as far as what the devteam has spent on what more visible.  I know it's a labor of love but in my opinion it should be fully funded.  Maybe making it visible that the people doing the technical work are also pulling the financial load will help resolve that. 

Or maybe not too.  People are greedy to the point of hurting themselves.

It is kinda frustrating to see other projects raise hundreds and thousands of BTC based on a whim and a promise...but then again, it does change the dynamic as respects the integrity of the project. If we're perpetually in the negative there's nobody's money we can run away with:-P

If all else fails, play victim of FUD.

Bunch of Legendary fags. This is why I got out of Monero. Yah I am ok to miss the Millionaire boat. You fags can go fuck each other all day long.

To give you some input on this from the Monero core team's perspective: we try keep the SNR in the Bitcointalk ANN thread as high as possible, and #monero-dev on Freenode has a pretty high SNR as well.

We do not sanction or control any of these other threads. In due time we will likely stop posting anything on Bitcointalk related to Monero apart from announcements in the ANN thread.

Can you adapt the existing 3rd GUI to save money?

No, it's double the work to first do an RPC hack-job and then follow it up with a proper, integrated solution.
939  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: September 16, 2014, 07:33:12 PM
Is there anywhere we can see the current dev fund status / amount?

The view key for the XMR fund is in the OP...we just need to provide tooling for that:) We've received around 25.3 BTC in XMR donations, and 7.80559 BTC in BTC donations, so a total of 33.10559 BTC. Actual expenses / contributor tips / freelancers / mathematicians+cryptographers / hosting have been significantly higher (in the region of 110 BTC excluding the core team's time), which we have been covering out of our pockets. In other words, we're in a perpetually negative balance.
940  Economy / Speculation / Re: rpietila Wall Observer - the Quality TA Thread ;) on: September 16, 2014, 06:17:26 PM
lol, I still don't get it.
Who or what prevents me from ring-signing your input and send your money to my address(output).
