Title: The impact of bad crypto (DASH, SDC, etc). How much does math matter?
Post by: TechorMarketing on April 22, 2016, 10:32:20 PM
Examples:

DASH high school math:

Hey, I heard that you can break InstantX. When can we expect that to happen? I will personally tip you if you do it. Don't disappoint me. Generalize this said you could.

I found a high school level probability math error in the InstantX white paper that had been there for a guess roughly a year and nobody had done the peer review. So this tells you there is no world-class development team.

The white paper was claiming astronomical odds of colluding masternodes able to corrupt the InstantX transactions. I showed the probability was much more reasonable.

DASH paper wallet faulty RNG (January 4th - April 5th, 2016):

Hello Everyone,

Unfortunately we broke paper.dash.org on January 4th and the seeding process for generating a wallet was insecure since then. There are no known Dash thefts that have taken place because of this (yet), but if you created a wallet using paper.dash.org between January 4th and April 5th, please move your money to a new place.

We take these kinds of issues quite seriously and believe it's our fiduciary responsibility to create the most secure environment for users to store value safely in our ecosystem. To address the issue we’ve reverted the patch that caused the issue and have also reverted paper.dash.org to an earlier, much safer version.

Thanks,

Evan Duffield

Clearly there are not enough qualified cryptographers to go around.  Is high school math good enough if you have fancy graphics and marketing materials that can attract interest from uneducated users? Is it realistic to expect copy/paste altcoin devs to produce the type of cryptographic research generated by MRL?

XMR / Monero broken crypto:

I think chainradar are using all the 0 mixin transactions from exchanges and pools in order to guess - the things in https://lab.getmonero.org/pubs/MRL-0004.pdf. I tried some transactions with mixing 7 and 5 between my wallets and they are successfully guessing most of them. This issue is already addressed in the MRL-0004 and we knew that, but it's scary seeing it in chainradar. Everybody should stop using mixing of 0 until this is enforced in the protocol - including pools and exchanges. I suppose some mixings between your own wallets with high mixing should resolve the issue for now. Trollfest incoming :(.

:'( :'( :'(

The issue was discovered and addressed by MRL. Since the latest hard fork 0 mixins are not possible (aside from a minor exception for dust transactions).

This issue is related to privacy not "bad crypto" or math errors. Monero now has a minimum mixin enforced for all transactions unlike DASH where DarkSend is optional and far less effective.

https://hellomonero.com/article/moneros-march-23-2016-hard-fork-what-you-need-know-updated
"Minimum mixin level has changed to 3.  Note that Monero does not use the term "mix" in the way other cryptocurrencies do.  A mixin is the number of ring signature partners that you have.  A mixin of 3 means that your transaction will be indistinguishable from 3 other partner transactions."

It's bad crypto alright. Monero users were transacting "anonymously" for a year only to discover later that they could be trivially deanonymized because those in charge hadn't fixed a "hole" in the system from the start.

As to the InstantX jamming theoretical attack:

The attack vector on InstantX was about the attacker owning hundreds or thousands of masternodes (ie paying tens of millions of USD to acquire them) just to ...jam a InstantX transaction, which, if failed, would go as a standard transaction.

So, the game theory of the attack vector is that someone will pay tens of millions of dollars to jam an instant x transaction, while undermining his money in the process.

Do you see that the game theory of the attack vector is completely broken in terms of costs to the attackers and gains for the attacker?

That's elementary logic right there.

It would be like saying "bitcoin is fundamentally flawed because someone could buy 51% of the mining equipment and attack it". Yeah, well, if they did that, their equipment would then be useless. It's an economic suicide for the attacker, so to speak. The game theory has to account for this, no?

The poll was not focused on privacy, the danger of high school level mathematics is far greater than that. The random number generator (RNG) error with the DASH paper wallet generator literally put users at risk of their entire balances being stolen.

It is.

Monero already fixed this problem in the recent hard fork by forbidding mixin 0 transactions.

Newsflash: not even the rng in bitcoin-qt is 100% reliable as i was hearing from the horses' mouth in the technical section somewhere. All your funds are at risk due to rng being not random.


And then again: "security" is always an illusion. Wishful thinking of a human mind afraid of pain and death. There is no good corespondence to the idea of "security" in the real world so it will likely forever be a chase for unicorns but i digress.
"Security" is just an idea fueled by whishful thinking. It can never be reached in reality.

The only thing that gives us something close to security is the fact that 99.99% of people are too stupid to understand what's happening if that makes sense?

There is no security behind the curve - none whatsoever

The "high school mathematics" mentioned were of the following type:

"If someone has XXX masternodes then they can jam an InstantX transaction X% of the time because InstantX locking is performed on the masternodes".

Cost for the attacker: Millions of USD to buy masternodes
Gains for the attacker: No gains. Only losses by devaluing his investment.

Elementary game theory logic = violated.

This was refuted at the time by:

https://github.com/fluffypony/chainradar-checker

Quote
I tested it against 19 transactions, some mixin 4 and some mixin 20 (excluding my own signature, so mixin 5 and 21 according to ChainRadar).

For these transactions none of them were completely compromised by ChainRadar, and ChainRadar got 0 out of 157 guesses correct.

If you are going to claim such a thing, please properly check it wasn't bogus/FUD.  



It's bad crypto alright. Monero users were transacting "anonymously" for a year only to discover later that they could be trivially deanonymized because those in charge hadn't fixed a "hole" in the system from the start.

Erroneous as well, like I've stated above and others pointed out as well.



Also, what is the point of opening these kind of threads? It will end in mud-throwing anyway. Ironically it already started in the first few posts here.

This was debunked both by fluffypony writing a program to analyze it (and showing the deanonymizing "results" obviously wrong) and later a reply from chainrader stating that it was just a bug in their web site showing wrong data and not even an attempt at deanonymizing at all. FUD/panic, in other words.

Mixin 0 was always a bad idea and a security weakness, no matter if a deanonymizing implementation was getting it right, wrong, or guessing.

Cost for the attacker: Millions of USD to buy masternodes

There is no such cost, since nothing is consumed. You still have the masternodes when you are done. If done as a malicious attack that reduces the value of the token, an attacker would have already stripped his exposure from his stake and resold it via derivatives. If merely done for spying purposes then you can continue to both spy and collect masternode rewards. This will outcompete honest masternodes over time since spying has economic value.

Yeah, well, if you want it that way, buying the monero supply to sybil all the mixins (a la BCN-83% "their mixin is insecure"), would also be a feasible economic attack. So XMR = REKT by the "theoretical" buyer of most coins  :'( :'( :'(

In practice it doesn't work that way.

Unlike masternode ownership that continues to pay rewards, that can't work without an ongoing cost post MRL-0004, given the math in MRL-0001 (not necessary to follow the math -- the chart showing the 'burnout' effect is good enough). Even Bytecoin could fix this eventually if they implemented a minimum mixing, although it would take quite a while for 82% premine to burn out.

These types of attacks where someone comes and buys all the coins are too theoretical for my preference.

All of the coins are not even needed for many masternode attacks. That was the point of the "incorrect high school math" discussion. In many cases the number required is far lower than "all". It is analogous to hash rate attacks which can be done with <50% hash rate, except that in the hash rate case, there is a cost when the attack doesn't succeed. In the masternode case that cost doesn't exist, because a node that is a laying-in-wait attacker is being rewarded at the same rate as any other node.

Also, I would guess a large part of the reason you dismiss these sorts of attacks is a false inference from the word "attack" as something that needs to be done on demand (i.e. go buy up all the coins quickly on an exchange -- which will obviously fail). A better way to phrase it may be "failed incentives", which can also occur over an extended period. For example, in PoW, mining becoming extremely concentrated is not an active attack (where you go and buy up all the hash rate quickly), it is something that may very well happen (and arguably has happened, at least to some extent) over time that still very much undermines the security assumptions of the system.

We are talking about ...jamming a transaction, after spending a shitload of money. And that's to jam 0.x% of instantx transactions that at worst will be confirmed 150seconds later per the casual block confirmation... that doesn't make any sense.

If it's a valid game theory scenario, and makes sense for the attacker, we'll see it happen. I don't see it happening.

I was talking about darksend spying, which you can't see happening, but is all but inevitable (and the only way out there is essentially an accidental miracle) given the incentives.

InstantX has other issues, worse than jamming, as far as not seeing it happening, there really isn't any incentive to even jam right now (who cares?). If it got to the point where Bitcoin is or even beyond, with real reasons for various interests to attack each other, that could and likely would be very different.

Analyzing soundness and especially over the longer term when it really matters is very different from just observing no one is attacking now. The same can be said for every single vulnerable system that has ever been attacked, looking at it the day before.

Well, the more you mix, the lower the probabilities of bad actors affecting you. That's pretty much the same across the board, in all mixing scenarios, including Cryptonote mixin settings.

The OP however refers to the "highschool maths" from a TPTB post about InstantX.

I've already explained the critical difference between the two. One has an ongoing cost to bad actors, the other does not. The lack of any quantifiable cost means is that attacks are plausibly unbounded. More mixing will not save you.

Was there any peer review of the InstantX white paper whatsoever? Was TPTB the first one to catch the error 1+ years later?

The elephant in the room is monetary properties, not technical ones. It's very simple, for tier 1 monetary assets:

Good crypto = Public Blockchains
Bad Crypto = Obscrued Blockchains

For higher order tiers (backed money, e.g. Bitcoin CT), obscured blockchains are acceptable.

So you should therefore be discussing the merits of Good/Bad crypto within the domain of Public Blockchains explicitly or Good/Bad crypto within the domain of Obscured Blockchains explicitly since they are distinct monetary domains and obscured blockchains do not have any native (unbacked) monetary properties in the first place - even if it is "good crypto".

If CT is ever implemented for Bitcoin itself (and segwit seems to make that more likely, even if only marginally), it will not be a higher order tier, it will be regular, ordinary main-chain Bitcoin transactions in which the amounts payable to each output are obscured (mathematically verifiable, but not visible in plaintext). You will no longer be able to look up addresses on a block explorer and see balances.

If implemented on a side-chain, I would consider that "higher tier" although I guess perspectives differ somewhat.

Nothing is "mathematically verifiable" except in theory.

Blockchains are not theory, they are practice.

That means they have to use technology that portends to implement theory but does not guarantee it. And even if they could guarantee it there's no way for an end user to ever know conclusively that they've got their hands on an authentic instance of that technology (except of course "in theory"  ;) ).

So for unbacked monerary tokens no blockchain is "verifiable" by anything other than mass visual inspection on an ongoing basis of every single address by the fare paying public, independently of whether they happen to be holders of private keys or not. It's the sociological endorsement that emerges from that shared consensus that supports the value, not "math".

And if CT is ever implemented for bitcoin itself then bitcoin will no longer be a tier 1 asset and no longer constitute viable money. (At least not in any sociological sense that could support its value).

Just for clarification, by "monetary tier", I meant this: If I use my bike as "money" to pay for something then the bike is the tier 1 money and the contract that says someone owns it is the tier 2 asset. The tier 2 asset can be obscured, burned, washed through the washing machine, without compromising the integrity or value of the tier 1 asset.

In crypto, obscured blockchains (such as CT) potentially have the job of record keeping and obscuring the ownership of a tier 1 asset (bitcoin). But they are not tier 1 assets in their own right (by virtue of being obscured).

So arguing about what constitute "good and bad crypto" when comparing public and obscured blockchain is like arguing which is more secure - the money or the safe.

this was an informative topic over all i didn't know a couple of these things that happened.

but generally i don't care that much about these things that is why i haven't heard about them. i am mostly into bitcoin and follow it closely.

so altcoins for me are just a way to earn some money from the pumps and trade them.

although i would be lying if i said i wasn't interested in altcoin at all, there are 1-2 projects that really interest me and i follow them (i am not naming them to prevent hate :D) but there is always some good projects out there. and as long as they are fixing theirs issues i am fine with it.

Why are there guys who try make simple things sound as complicated as possible to obscure the truth and there are guys who try to make complex things as simple as possible to reveal the truth?


The visibility of the transactions in the blockchain enables anyone and everyone to confirm the validity of the ledger. Cryptonote does not have this visibility, therefore the validity of the transactions cannot be confirmed, which means there is no independent way of verifying that the implementation or the protocol have not been broken.

It could be broken, we dont know and we have no way of showing that it is not being exploited right now.

That's not true. You can verify Monero's coinbase as you do in Bitcoin.

Yes, but not the rest of the chain unfortunately.

Not sure what you're talking about, even when CT is implemented, you can still validate the coin total.


"[–]fluffyponyzaXMR Core Team 3 points 2 months ago

"So, having only the blockchain data, is it possible to mathematically prove that all blocks inside followed the rules?"

Yes - read gmaxwell's write-up on CT and you'll see that amounts can still be verified.

To illustrate it as simply as I can: imagine if every transaction input was 1000 XMR. But, using ring signatures, you mix your real input of 55 XMR with a bunch of other ones that adds up to 1000 XMR. Analysing the blockchain we can still verify that it adds up to 1000 XMR, but we can't tell which value is yours."

You are still singing this tune, eh?

For those just tuning in, you should know that this guy is responsible for the brilliant statement of

"Cryptography has never been a significant part of cryptocurrency - even though it may share the first few letters. "

This occurred during a very heated debate in what I hoped we could consider "classic" DASH vs XMR threads, which were quite literally 1 year ago.

https://bitcointalk.org/index.php?topic=1001642.msg10921597#msg10921597

Cryptography has never been a significant part of cryptocurrency - even though it may share the first few letters. It works on a system of digital signatures.
It would seem that you actually do not understand what cryptography is in the modern sense.

A fundamental nature of information is that it wants to be freely copied everywhere to everyone. That any bit is equal and indistinguishable from any other bit of the same value and that any bit is eventually known to all who care.  Cryptography is all that technology by which we hope to confine and constrain the nature of information, to put up fences and direct it to our exclusive purposes, against all attacks and in defiance of the seemingly (and perhaps actually) impossible.  Digital signatures are cryptography by any modern definition and utilize the same tools and techniques (for example, a DSA signature is a linear equation encrypted with an additively homorphic encryption), and suffer from most of the same challenges as the message encryption systems to which you seem to be incorrectly defining cryptography as equivalent.  Moreover, the use of digital signatures isn't the only (or even most relevant) aspect of cryptography in cryptocurrencies-- e.g. the prevention of double spending of otherwise perfectly copyable and indistinguishable information in a decentralized system is a cryptographic problem which we address using cryptographic tools, and-- like all other practical cryptography-- achieve far less than perfect confidence in our solution. As are more modest ends like interacting with strangers but not being subject to resource exhaustion from them.

Far more so than other sub-fields of engineering, cryptographic systems are doing something which is fundamentally at odds with nature and share an incredible fragility and subtly as a result (and perhaps all are failures, we have no proof otherwise).

A failure to understand and respect these considerations has resulted in a lot of harmful garbage and dysfunctional software.


And then by andytoshi

Can you (or Tok) point to a part of a cryptocurrency which isn't cryptography?

the dev team, the website, any part of the wallet not doing a cryptographic function, the buyers, the masternode operators, the network transport, whatever isn't going into a cryptographic function.

This thread is moving pretty quickly (ten pages of mudslinging in half as many hours!) so I'm not sure you'll see this, but there's an important misunderstanding here. You're right that the human beings aren't cryptographic (e.g. the development team, market participants, etc) --- though it's important to observe that this makes them very unsuited to cryptographic functionality. gmaxwell had an elegant description of cryptography as "technology by which we hope to confine and constrain the nature of information" despite information respecting no ownership, borders or morality. He described this as "inherently subtle and fragile", which it is, but this indifference to political and social pressure also make it efficient (human trust is expensive to build and maintain!) and robust against a lot of political and social pressures that human systems are not. This robustness is the cypherpunk motivation for bringing cryptography into everyday life: anything we have the technology to do cryptographically rather than socially ought to be, since social systems can change quickly and unjustly. Nowhere is this more true than finance, so cryptocurrency is a perfect environment for this kind of thing. So cryptocurrencies try to eliminate human decision points wherever possible, and where not they try to set things up so others can't override each others' decisions (hence the value implied by buzzwords like "decentralization" and "censorship resistance" and "public verifiability").

I'm not entirely clear on what masternodes do these days, but I infer that their actions affect users' privacy, i.e. they are "confining and constraining" information. This is a cryptographic function too. Human decisions may factor into their behaviour, but they are still performing a cryptographic function; human involvement does not change this, only changes the failure modes.

All this to say that basically the entirety of cryptocurrency really is cryptography. Even many of the human parts. The network transport is part of the cryptosystem: it needs to be designed to prevent modification of data in transport, authentication of data even when endpoints are anonymous and spoofable, etc. A wallet is part of the cryptosystem: it's responsible for creating verification keys ("scriptPubKeys" in Bitcoin, which are usually abbreviated to addresses) whose corresponding private keys are controlled by the correct parties to the correct extent, and for correctly and securely storing these keys. Wallets are decoupled from the main cryptocurrency cryptosystem, and in particular are not part of the hard part --- consensus code --- but they are certainly cryptographic and are subject to the same sort of subtle missteps as other cryptosystems. (For example, the oft-cited BIP32 "bug" where a party in possession of a public key and chaincode can derive the secret key from a non-hardened child secret key; it would not be hard to come up with a plausible-sounding system which "unintentionally" exposed secret data through this mechanism.)

I'll repeat my above statement: basically the entirety of cryptocurrency really is cryptography. This is important. It's why things are so subtle, why complexity is dangerous, and why changing even trivial-seeming things can have drastic and hard-to-analyze consequences. This is where "a lot of harmful garbage and dysfunctional software" comes from. It's the default for poorly-thought-out systems. And in cryptography, "poorly thought out" means anything less than expert cryptographers spending large amounts of time and effort designing things to be both correct and clearly correct. (Given how few experts there are in the cryptocurrency space, I could tell you that almost all of it is shit just by the pigeonhole principle :).)

This is not a cheap standard to hold a system to even if its designers want to; and falsely claiming that something is not cryptographic is an easy way to excuse not wanting to. But such claims do not change reality.

The encryption of data through cryptography is the foundation of cryptocurrencies.

This is simply false.



At the end of the day, reader, whomever you are, you are obviously free to do whatever you wish and listen to whomever. Just know who (and what) you're getting in bed with.

Post by: AlexGR on April 23, 2016, 05:11:10 PM
We are talking about ...jamming a transaction, after spending a shitload of money. And that's to jam 0.x% of instantx transactions that at worst will be confirmed 150seconds later per the casual block confirmation... that doesn't make any sense.

If it's a valid game theory scenario, and makes sense for the attacker, we'll see it happen. I don't see it happening.

I was talking about darksend spying, which you can't see happening, but is all but inevitable (and the only way out there is essentially an accidental miracle) given the incentives.

Well, the more you mix, the lower the probabilities of bad actors affecting you. That's pretty much the same across the board, in all mixing scenarios, including Cryptonote mixin settings.

I've already explained the critical difference between the two. One has an ongoing cost to bad actors, the other does not.

You are leaving aside multiple costs for the bad actor. Devaluation for the coin by harming it, inflation costs for the holder (which are only partially mitigated by masternode rewards, yet maxcoins is >3x of current supply), mass acquiring costs that lead the price upwards (it's not the same, in terms of market-prices, buying 100 dash and 400.000 dash to buy 400MNs), etc.

Quote
The lack of any quantifiable cost means is that attacks are plausibly unbounded. More mixing will not save you.

If you involve 1 MN for mixing, and 10% of them are crooked, you have 10% of being deanonymized by hitting the crooked MN.
If you go in 2 rounds, with 2 different MNs, your chances go to 10% of 10%.
In the third round you have 10% of 10% of 10% chance.
...etc etc.

Multiple round mixing was designed specifically to address the bad actor scenario.

Quote
Was there any peer review of the InstantX white paper whatsoever? Was TPTB the first one to catch the error 1+ years later?

The "error" involves broken game theory for the attack vector.

If we are just trying to find theoretical "dangers" but ignoring the underlying game theory, then Bitcoin and all crypto are already dead. They aren't because they are based on game theory, costs and rewards for the attacker etc.

Now don't try to distract from this gigantic design error by citing "probability" or similar nonsense! It doesn't change the fact that anyone hit by a meteorite is going to die even though he or she was wearing clothes! That's why I decided to stay naked for the rest of my life, because it's not going to make any difference when the meteorites strike!

Not even. Evan asserted that tptb had miscalculated something and ran away after tptb corrected him. The same thing happened when I confronted Evan about X11--though I had some help from Shelby on understanding the problem.

He has since changed his opinion of Shen and admitted he's a more than capable cryptographer--his opinion of Evan has gotten worse over time, but nice attempt to change the subject.  ::)

You'll have to ask Shelby. My guess is he'll tell you before you get a chance to ask, but my point is that Evan runs away when he can't explain a failure. Shen actually argued with Shelby for days, but then again, Shen knew he was right and didn't need to run.

Unlike people wasting their time on forums mudslinging, Evan uses his time to code the next features of DASH.

If he sits here debating all day then we'd hear: "doesn't he have anything better to do, like code?"

If he codes and doesn't debate endlessly the (self-defeating - from a game theory perspective) scenario of ...jamming an instantx transaction after acquiring a large number of masternodes => "he run away".

You can spin it any way you want really. It doesn't matter.

If you think mudslinging is a good tactic for promoting Monero, then be my guest. You'll be actively contributing to defining what bad crypto is: Crypto that wants to rise not by virtue of its better characteristics, but by throwing mud at their opponents.

This is now, what? The 10th thread or so of "Monerotards" attacking DASH? Get a life. Or a better coin. Then the market will appreciate it, if it becomes such. You won't get any value from the market without providing value to the coin. Even if DASH never existed, Monero would still be stuck. Contemplate that for a change.

You couldn't spin the narrative away from Evan's shortcomings, so you're going to take your ball and what? I guess the apple doesn't fall from the Dev. Now, as for mudslingin', you just threw a hissy about Monero's mudslinging while calling us Monerotards, and while your quoting someone to do it, you're still doing it. I'd rather not get into a hypocrisy debate, but grow the fuck up. We're all big boys here and should be able to take it as well as we dish it--but I'm sure you're preaching the anti-mudslinging mantra to Tok, Ceti, and Macrochip.

As far as markets go,  given Monero's volume compared to Dash's, I think we are doing just fine--imagine if we had 3,700,000 coins locked up in a masternode scheme?

Now the thread is completely derailed from the hs math versus cryptography, but seeing how Evan isn't good at hs math, maybe the thread should ask if middle school math is good enough?

I don't know the details of whatever feedback TPTB provided there -- it may or may not have been helpful in particular -- but I know more generally that several qualified experts have also read it and helped to correct errors, clarify ambiguities, and improve the clarity of the presentation.  Yes, that is how you do science.

Evan is accountable to his coin holders, not his tyre kickers.

Agreed. And in that respect, watching promoters of obscured blockchains attack "real" crypto on security or ideological grounds is a bit like watching football fans yell instructions at the players after drinking several pints of beer.

Gold futures on the other hand are not a public blockchain. They are paper contracts which you cannot see and are kept private due to the fact that they're associated with an individual. But then again, gold futures are tier 2 monetary media - a piece of paper that is backed by gold.

So even by that analogy:

Gold = Part of the "metals" public blockchain with address 79 in the periodic table that is inspectable by anyone
Gold futures = obscured blockchain that is only any use as long as its "backer" (the public blockchain metal) exists

You're trying to push the idea that because someone can hide a piece of gold under their bed, that means obscured blockchains can have "value".

That reminds me of my 6 year old daughter who thought because she had 6 coins in her piggy bank she could buy a house.

Unbacked monetary media take a very long time to garner individual trust, then public trust, then public consensus, then public endorsement. Only after that "right of passage" phase comes value anything like the status of gold.

The only reason gold gained any value in the first place was because it got kicked about in the open for thousands of years and was found to posses true monetary properties (which are very rare). But it was public consensus that ultimately endorsed its value. That led to hoarding.

But Gold never had any obscurity of its own. If it had done it would never had got past the value of sand.

Thats the difference between the view that you are expressing and that of what I'm posting here.

Just read your own post again:

Do you realise you're talking about gold ?

Nothing could be less obscured. It's lying around in the hills. An open secret. Analysed to death, has a place in the periodic table. If ever anyone even stumbled on a piece of gold there are a myriad of reference points for them to verify it. Even if you don't own it you can still verify it. It is what's known as a "bearer token" because after gold there is no further you can go in the chain of trust.

So it is with public blockchains. There is a reason why satoshi did not obscure the blockchain - even though anonymity was the priority - and that reason is plain as day to anyone who understands how gold acquired its value.

Did Monero's emissions and transactions suddenly become unverifiable?

The reason I ask is that all I need or want is to know the supply is as stated and that my amount is secure and that I can send stuff without it being broadcast to the whole world. As long as Monero does that, it has all the money properties I want--seems kind of stupid to tell me I'm wrong about I want.

If you want centralized money that everyone can see, that's your business, just don't call it anything else--and don't tell me the instamine is redistributed because you read some market tea leaves.

The elephant in the room is monetary properties, not technical ones. It's very simple, for tier 1 monetary assets:

Good crypto = Public Blockchains
Bad Crypto = Obscrued Blockchains

For higher order tiers (backed money, e.g. Bitcoin CT), obscured blockchains are acceptable.

So you should therefore be discussing the merits of Good/Bad crypto within the domain of Public Blockchains explicitly or Good/Bad crypto within the domain of Obscured Blockchains explicitly since they are distinct monetary domains and obscured blockchains do not have any native (unbacked) monetary properties in the first place - even if it is "good crypto".

You are still singing this tune, eh?

For those just tuning in, you should know that this guy is responsible for the brilliant statement of

That any bit is equal and indistinguishable from any other bit of the same value and that any bit is eventually known to all who care.  Cryptography is all that technology by which we hope to confine and constrain the nature of information, to put up fences and direct it to our exclusive purposes, against all attacks and in defiance of the seemingly (and perhaps actually) impossible.  Digital signatures are cryptography by any modern definition and utilize the same tools and techniques (for example, a DSA signature is a linear equation encrypted with an additively homorphic encryption), and suffer from most of the same challenges as the message encryption systems to which you seem to be incorrectly defining cryptography as equivalent.  Moreover, the use of digital signatures isn't the only (or even most relevant) aspect of cryptography in cryptocurrencies-- e.g. the prevention of double spending of otherwise perfectly copyable and indistinguishable information in a decentralized system is a cryptographic problem which we address using cryptographic tools, and-- like all other practical cryptography-- achieve far less than perfect confidence in our solution. As are more modest ends like interacting with strangers but not being subject to resource exhaustion from them.

Far more so than other sub-fields of engineering, cryptographic systems are doing something which is fundamentally at odds with nature and share an incredible fragility and subtly as a result (and perhaps all are failures, we have no proof otherwise).

A failure to understand and respect these considerations has resulted in a lot of harmful garbage and dysfunctional software.


And then by andytoshi

Can you (or Tok) point to a part of a cryptocurrency which isn't cryptography?

the dev team, the website, any part of the wallet not doing a cryptographic function, the buyers, the masternode operators, the network transport, whatever isn't going into a cryptographic function.

This thread is moving pretty quickly (ten pages of mudslinging in half as many hours!) so I'm not sure you'll see this, but there's an important misunderstanding here. You're right that the human beings aren't cryptographic (e.g. the development team, market participants, etc) --- though it's important to observe that this makes them very unsuited to cryptographic functionality. gmaxwell had an elegant description of cryptography as "technology by which we hope to confine and constrain the nature of information" despite information respecting no ownership, borders or morality. He described this as "inherently subtle and fragile", which it is, but this indifference to political and social pressure also make it efficient (human trust is expensive to build and maintain!) and robust against a lot of political and social pressures that human systems are not. This robustness is the cypherpunk motivation for bringing cryptography into everyday life: anything we have the technology to do cryptographically rather than socially ought to be, since social systems can change quickly and unjustly. Nowhere is this more true than finance, so cryptocurrency is a perfect environment for this kind of thing. So cryptocurrencies try to eliminate human decision points wherever possible, and where not they try to set things up so others can't override each others' decisions (hence the value implied by buzzwords like "decentralization" and "censorship resistance" and "public verifiability").

I'm not entirely clear on what masternodes do these days, but I infer that their actions affect users' privacy, i.e. they are "confining and constraining" information. This is a cryptographic function too. Human decisions may factor into their behaviour, but they are still performing a cryptographic function; human involvement does not change this, only changes the failure modes.

All this to say that basically the entirety of cryptocurrency really is cryptography. Even many of the human parts. The network transport is part of the cryptosystem: it needs to be designed to prevent modification of data in transport, authentication of data even when endpoints are anonymous and spoofable, etc. A wallet is part of the cryptosystem: it's responsible for creating verification keys ("scriptPubKeys" in Bitcoin, which are usually abbreviated to addresses) whose corresponding private keys are controlled by the correct parties to the correct extent, and for correctly and securely storing these keys. Wallets are decoupled from the main cryptocurrency cryptosystem, and in particular are not part of the hard part --- consensus code --- but they are certainly cryptographic and are subject to the same sort of subtle missteps as other cryptosystems. (For example, the oft-cited BIP32 "bug" where a party in possession of a public key and chaincode can derive the secret key from a non-hardened child secret key; it would not be hard to come up with a plausible-sounding system which "unintentionally" exposed secret data through this mechanism.)

I'll repeat my above statement: basically the entirety of cryptocurrency really is cryptography. This is important. It's why things are so subtle, why complexity is dangerous, and why changing even trivial-seeming things can have drastic and hard-to-analyze consequences. This is where "a lot of harmful garbage and dysfunctional software" comes from. It's the default for poorly-thought-out systems. And in cryptography, "poorly thought out" means anything less than expert cryptographers spending large amounts of time and effort designing things to be both correct and clearly correct. (Given how few experts there are in the cryptocurrency space, I could tell you that almost all of it is shit just by the pigeonhole principle :).)

This is not a cheap standard to hold a system to even if its designers want to; and falsely claiming that something is not cryptographic is an easy way to excuse not wanting to. But such claims do not change reality.

The encryption of data through cryptography is the foundation of cryptocurrencies.

This is simply false.



At the end of the day, reader, whomever you are, you are obviously free to do whatever you wish and listen to whomever. Just know who (and what) you're getting in bed with.

I believe toknormal is intentionally being disingenuous by pretending to not understand that zero-knowledge proofs and homomorphic functions are long-established and well-tested forms of good crypto.

It is typical for DashHoles like tok to attempt bamboozling noobs with FUD about how "zomg if a coin's blockchain is 'Obscrued' (sic) how do U NO there are only X number of coins?"

Dash: The privacy coin for those not educated sufficiently to understand ZKPs.

If tok wanted to understand good crypto rather than merely FUD against Monero, he would read and understand this:

https://en.wikipedia.org/wiki/Zero-knowledge_proof

Nobody should listen to tok's ham-fisted gainsaying and dissembling.  Given the humiliating epic spanking he got from gmax and andytoshi, I'm surprised he's not too embarrassed to continue making a fool of himself here.  But then again he's probably trying to protect his bags of DarkDashDuffCoin, and may even be paid for his promotional/propaganda/browbeating efforts.

I get the feeling your idea of unverifiable is much different than mine. The same as your idea of privacy is different than mine. Or good cryptography. Or what constitutes fair distribution.

So do you think Monero's cryptography is broken or are using the "I don't understand it, so therefore no one will use it" attack/defense?

No more broken than SSL.

But SSL is not a store of value. It is a decentralised cryptographic messaging system. Invest in it if you like it.

The only thing that distinguishes a cryptographic messaging system from Bitcoin is that Bitcoin is a public blockchain and cryptographically obscurred blockchains are not.

Thats what makes Bitcoin money.

If it was not a public blockchain and everyone could not inspect every single address - regardless of whether they possesed a private key to that address or not - then it would not constitute (base) money.

I can see my balance and I can see my transactions and I know that the ring signitures work, so I don't need anyone (especially a wanabee economist) to tell me that I need to see other people's balances for it to be money. I think you missed the meeting where we discussed that the highest form of human functioning is to think in the abstract, to imagine concepts into being.

Firstly, in this case, we're talking about unbacked money, so I'm afraid you do.

Secondly, a blockchain is anonymous - like a rock. So the fact that you hold a piece of it doesn't endow it with your identity. Nobody is therefore "seeing your balance" by catching sight of that piece of rock.

You can relax.

Are you stupid or does metadata not exist in your myopic view of the world--it's rhetorical. It's backed by the cryptography being secure and the parameters that the miners agree upon--so no, I don't need to see what happens to the transactions that don't belong to me.  This lackadaisical attitude towards privacy explains dash's shoddy design-- "just relax, we've got it all under control, OSPEC? That's overkill, just put your node on amazon."

Also, your idea of money falls flat on its face when applied to a coin that uses an insecure chain like X11. An attack can go on for so long that there is no way to roll back the chain as a fix--so maybe, just maybe, the cryptography is more important than just a bunch hs mathers eyeballing the blockchain and saying, "Looks good, must be money."

The only sure way to gain respect in the Bitcoin community is to contribute code.

Why would I want respect from the community of a coin with a broken design that I aim for my project to supercede  ???  (note no one is excluded from leaving the broken design and joining the winner)

iCEBREAKER, just admit you can't understand what I wrote at the linked research.

Good to see iCEBREAKER is still going to need some proof from me. I love the competitiveness.

Sorry when I build up Monero because I state facts that are true about it, it doesn't mean anything has changed in terms of my plans. Hell will freeze over before I will ever write a line of code for Monero[1]. No disrespect to those who created Monero, they will be welcome to join the winner.

(can you tell I am getting healthy now, lol)

[1] I am not going to get involved in any C++ source code bases, so no bitcoind and no Monero. I know C++ since I wrote CoolPage (million user app) in it, but been there, done that, never again. More importantly, I want to change the world, so I am not going to get involved with designs that can't possible scale to 1 million transactions per second. That would be a waste of my legacy. And I am not going to get involved with communities that are off in their little corner of the internet and haven't attracted superstar non-anonymous programmers. I want to see LinkedIn accounts and career history plus major accomplishments. Gmaxwell and Adam Back don't count, because they are number theoretic/cryptography nerds. They are not systems engineers (which was obvious in my technical debate with gmaxwell regarding the indexing of streaming audio formats) and certainly not savvy marketers for the large scale adoption we need. Honestly I think smooth is very smart, but I have no idea who he is and what he has done in his career in detail. I have some vague public rumor (and his private statement) that he worked in FinTech.

Not quite. I said Bitcoin is broken and both can't scale to million tx/s. But that doesn't make Monero broken for its target market. Bitcoin is broken both for scaling and for centralization of mining. Monero has advantages on the latter and also adds strong privacy.

My reasons for not wanting to be folded into the development group of Monero, is because I would be a little fish in a little pond. And I am not enthralled about coding on C++ code bases. So what is the redeeming factor, when I have so much opportunity and excitement on what I am working on now? I find it a bit insulting (but more humorous and motivates my competitive fire) when iCEBREAKER and americanpegasus insinuate that the only useful coding I could do in this world would be on the itsy bitsy coins they own. That is because they are speculators and not developers. The developers don't say that to me, because they know better.

I thought you were referring specifically to the bloat issue that affects monero's scaling way more than bitcoin since bitcoin doesn't suffer from the same problem.

Regarding Monero's anonymity, do you stand by the statement you've expressed below in the past (regarding broken anonymity due to metadata correlation)?

Cryptonote was created by anonymous people. Even Monero's cryptographer is anonymous. Who created this anonymity that is easily broken by meta-data. I don't know if that is circumspect or just the way the world turns.

As for scaling... well scaling is a complex equation involving time, technology available, proper use of the available technology and the ratio of centralization/decentralization that is "acceptable" at any given moment.

We could say that everything can scale (if...) or everything can't scale (if....), or everything can scale in (x time), or under (z circumstances).... etc etc. The good thing with scaling is that unlike hardware and software progress, human tx needs are finite and thus the two trajectories (of increased tech progress vs finite human tx needs) will meet. If we currently, as a species, say, need 100k tx per second, there is a point where this will be feasible. And as time progresses we will be able to handle a million, ten millions, etc etc. But tx needs will still remain in a pattern of relative stability - slow growth.

Sigh, he also said dash is the worst of the three, so if you're going to use him as an authority figure, you have to accept that analysis. The enemy of my enemy is my friend until they become friends with my enemy because they just don't like you very much.

Smooth has pointed out that metadata isn't the problem that Monero was designed to solve and it's still up for I2p and TOR and other anonymous networks to prevent metadata collection. Dash doesn't even solve the problem that Monero solves and dash even finds ways to create new problems, like having an instamine and node incentives aggregate power into the form of an oligarchy.

That is true, the problem is largely independent. If your network traffic is being spied up, then you will have the same or worse (probably much worse) problems with Bitcoin or Dash or any other coin.

Also, no one involved with Monero has ever claimed it is 'NSA-proof'. The most we have ever said is that it continues to improve and could possibly, someday, reach a point of being reasonably NSA-proof if coupled with good OPSEC (as something like PGP might be considered today), but that is certainly not a realistic short term goal.

Scaling "10 times better" is frankly pretty ridiculous. There isn't any clear metric by which one would define a numeric comparison "scaling". In some ways Monero scales better than Bitcoin, in other ways worse. In some of the most important ways (such as bandwidth required for full nodes), they are very close. Bitcoin might have a small edge if you ignore additional Bitcoin traffic created by JoinMarket and other forms of mixing in order to try to do (worse) what Monero does natively.

Anyway, scaling has little if anything to do with what experts call "bad crypto". In fact, making crypto worse and using smaller key sizes, etc. could help with scaling.

Monero is not anonymous when your metadata can be correlated. One example of metadata which unmasks your anonymity is your IP address. And no, Tor and I2P mixnets do not hide your IP address from the government, in fact they are thought to be Sybil attacked honeypots that not only tell the government your IP address but also alert the NSA et al that you should come under extra scrutiny.

Congratulations. You passed your "broken crypto" review with flying colors.

Monero #REKT  :'( :'( :'(

So I wonder if you're some sort of reverse troll. Why? Two reasons: First, TPTB_need_war has more and harsher criticisms of dash, so the best you can do is make dash look worse than Monero. Second, you're taking many of TPTB_need war's statements out of context and purposely removing the time stamps to mask that many of those quotations are very old and do not reflect his current understanding of Monero--which is probably going to piss him off and entice him to find more failures in dash--though that list is long already.

So who are you working for? Because you're not doing dash any favors  ;)

Scaling "10 times better" is frankly pretty ridiculous.

It may be, on the lower side. It could be worse than 10x.

What's your blockchain size right now?

Blockchain size is not a measure of scalability (and as I said there is no useful numeric comparison of "scalability"), but the size is something like 2.5 GB.

So bitcoin is like 25x in terms of blockchain use, but has 2k-3k txs per 10 minutes.

Monero, from the looks of it, has not even 10 txs in the last hour.

Anyway, let's say btc does 200k txs per day and monero does 200 txs per day. That's 1000 to 1 in terms of txs, yet the blockchain isn't 1/1000 of BTC, it's 1/25.

My 10x may be very conservative.

Actually I'm doing precisely that. You are the (normal) trolls and I'm trolling you back. As you said it. Reverse troll.

In the context of this thread, it is a "given" that dash is bad crypto (just look at the title), so there's nothing to debate there. The OP made his mind based on a paper wallet generator and a theoretical instantx jamming scenario. So let's see what the "good crypto" is... and when you look more carefully, the self-proclaimed good crypto is broken everywhere :'( :'( :'(

It took me 30 seconds to find out that this is BS:





Quote

I can't always use time-stamped quotes on locked threads with the "quote" button. That's why I'm inserting a link instead where this is not possible.

https://bitcointalk.org/index.php?topic=1319681.msg13575212#msg13575212 (https://bitcointalk.org/index.php?topic=1319681.msg13575212#msg13575212) Here's one of your unattributed quotations that wasn't locked, are the rest as locked?

And here's me quoting it with the quote button (*notice it's 3 months old).

Monero is not anonymous when your metadata can be correlated. One example of metadata which unmasks your anonymity is your IP And IP address is not the only metadata that can destroy your anonymity in ring signatures. Other examples can include cookies in your browser and other activity you did on the web. Other examples also include telephone calls and other activity you did around that time, which have statistical significance.

And here's what he says today on this thread (which you may or may not read in full).

Now that you quoted the entire post, does it change the fact that he says MONERO IS A BROKEN DESIGN?

Not quite. I said Bitcoin is broken and both can't scale to million tx/s. But that doesn't make Monero broken for its target market. Bitcoin is broken both for scaling and for centralization of mining. Monero has advantages on the latter and also adds strong privacy.

My reasons for not wanting to be folded into the development group of Monero, is because I would be a little fish in a little pond. And I am not enthralled about coding on C++ code bases. So what is the redeeming factor, when I have so much opportunity and excitement on what I am working on now? I find it a bit insulting (but more humorous and motivates my competitive fire) when iCEBREAKER and americanpegasus insinuate that the only useful coding I could do in this world would be on the itsy bitsy coins they own. That is because they are speculators and not developers. The developers don't say that to me, because they know better.


And what he says comparing dash and Monero's privacy on this thread.

Regarding Monero's anonymity, do you stand by the statement you've expressed below in the past (regarding broken anonymity due to metadata correlation)?

Cryptonote was created by anonymous people. Even Monero's cryptographer is anonymous. Who created this anonymity that is easily broken by meta-data. I don't know if that is circumspect or just the way the world turns.

Against the NSA yes I stand by the assertion that IP address correlation unmasks, overlapping rings unmask, etc. It all adds up if you are trying to hide from governments, then I don't trust Monero or any anonymous coin. Notice I wrote "privacy" and not anonymity in prior post upthread. For privacy, I think Monero is suitable and Dash is not (because not autonomous End-to-End).

I guess my quote button works fine, maybe you should hire an expert to look over your system to see what's wrong instead of just accepting it as broken.

The 2.5 GB is not proportional to the past hour, nor is the past hour representative of all hours. A huge portion of of the entire chain, perhaps half or more, was created within the first few months due to immature pool software doing payouts stupidly, and also when there is occasionally much higher activity (during pumps, mostly). Bitcoin also didn't have that sort of usage for whole lifetime; for the first year or two it was close to dead, and up until last year the usage was significantly lower. With 2k-3k tx/block during its entire life, Bitcoin's blockchain would be much more than 25x bigger.

Overall these sorts of crude comparisons just don't make sense, and just show you are more interested in trolling than thinking.

Actually, now that you mention it, I haven't even factored that BTC's blockchain is 7+ years old vs 2 years old of XMR.

Anyway, let's make a hypothetical here.

How much bloat would Monero generate for 20.000 tx per day (1/10th of what bitcoin does), at a relatively low mixin level 3.

I just insert quote / unquote by hand if it's from the SAME post that I'm quoting. I quoted 4 pieces. The first has the timestamp, the second, right below it, doesn't need to. It's the same post (as the first).

The third (from a locked thread) isn't quotable, so I'm just inserting the message link. The fourth doesn't need the link again. It's the same post (as the third).

In case anyone is stupid enough to don't get it, there are "..." between (quote 1/quote 2) and (quote 3/quote 4)

But then again, arguing about quotes, timestamps, trolls, etc, seems to be all that you can do in this debate where XMR is proven to be bad crypto  :'( :'( :'(

A typical transaction is like that is 2-3 KB compared to maybe 0.5 KB on bitcoin (rough numbers), so a ratio of about 5x. That's still not a valid comparison, because if people ever use any kind of mixing services on Bitcoin (and they do), that makes up part of the higher tx volume and reduces the effective ratio. BTW, the same argument has been made by Adam Back with respect to CT's larger transactions. You have to compare not only transactions numbers and size, but adjust for some sort of equivalent level of functionality per transaction.

The typical btc tx is around 0.3kb, so, at 2-3kb for monero we are talking 6.6-10x.

I understand all the different characteristics, but it's precisely these characteristics that give the bloat.

The FRAUD and SCAM exposed:

Quote
https://github.com/monero-project/bitmonero

Introduction

Monero is a private, secure, untraceable currency. You are your bank, you control your funds, and nobody can trace your transfers unless you decide so.

The "brochure" is fraudulent.

The claims are false.

This is false marketing with dangerous RL consequences.

Every chain has a degree of spam, that's included in the 2.5 GB Monero chain as well. In reality the 7 TPS benchmark (which comes to 240 bytes) for Bitcoin just turned out to be an unrealistic ideal scenario, or at least unrealistic unless extreme transaction packing efficiency is forced by high tx fees. But that too applies to every chain in various ways. For example here is a mix 4 transaction that is only 758 bytes. If people really cared about fees, transactions would likely be constructed in a more compact manner. YMMV.

I guess it's solvable by higher fees that promote more efficient ways to use the blockchain but then you have to face the social-engineering attack vector "ohh my gawd these fee increases are killing adoption", etc etc.

I find it fascinating how Alex misses that the worse he tries to make Monero look, the worse dash looks--I never asked for NSA proof transactions, nor was I promised them, but I would like protection from non-state actors, and if the right network evolves within I2p or TOR or something else, then a coin that can be NSA proof would be even better, so no dash, yes Monero.

Again, you're conflating metadata that requires your OSPEC to be on point and the network you are interacting with not to leek information with Monero's technology--so this is like blaming a car company for traffic accidents caused by the absence of a stop sign. The car company can only do so much, but in dash's case they forgot the airbags and brakes.

Animosity is not good. We're just having fun here with our altcoins (or "shitcoins" for others - depending one's view I guess) :D

Just 5 minutes of anger can cause one's immune system to underperform for up to 7-10 hours or so.

On the other hand, 5 minutes of loving feelings (gratitude, appreciation) can have the same positive effect to the immune system, extending for several hours.

The "battle mode" that one might engage in while foruming and debating in troll threads, is not really conductive to one's health. It must be viewed as a fun exercise.

My father was a genius (he was a code breaker during WWII and into the Korean War) and my mother was a schizophrenic, and while my father's logic skill set and knowledge base were vastly superior to my Mother's, she regularly won arguments by using emotional triggers to get him out of his game--that education has served me well for BCT (don't let the them anger or frustrate you with the same invalidated points over and over again or attempt to steal the narrative, but find creative and efficient ways to bolster the important points, and when they just hand you one, well....).

Ladies & Gentlemen, I present to you the Toknormal Memorial DashHole Ignorance Hall of Fame.   :D

Gold is a public blockchain

Cryptography has never been a significant part of cryptocurrency - even though it may share the first few letters.



ROFL!

Yup and silver is also public as well. Would love to see ALL balances of silver holdings of every person on planet earth and alien's in other solar systems as well.

Thanks ahead of time Tok! :D

Now that you quoted the entire post, does it change the fact that he says BITCOIN IS A BROKEN DESIGN?


FTFY

Now apologize for misreading and misquoting what was pretty obvious for anyone with high school reading skills.

Yeah because if he considers bitcoin as "broken" due to its scaling which is 10 times better than monero, then monero ...isn't broken :D

Dat logic.

And he also asserted time and time again (even two posts above) that the anonymity is broken against the state due to metadata correlation.

Quote
Against the NSA yes I stand by the assertion that IP address correlation unmasks, overlapping rings unmask, etc. It all adds up if you are trying to hide from governments, then I don't trust Monero or any anonymous coin.


#badycrypto XMR  :'( :'( :'(


Sigh, he also said dash is the worst of the three, so if you're going to use him as an authority figure, you have to accept that analysis. The enemy of my enemy is my friend until they become friends with my enemy because they just don't like you very much.

Smooth has pointed out that metadata isn't the problem that Monero was designed to solve and it's still up for I2p and TOR and other anonymous networks to prevent metadata collection. Dash doesn't even solve the problem that Monero solves and dash even finds ways to create new problems, like having an instamine and node incentives aggregate power into the form of an oligarchy.

You folks may be wasting your time arguing and going back and forth with people who are all about diversions.

Once they attempt to make a point and have it debunked by their either conscious or ignorant nature they instantly change the subject and point in another direction while not admitting to their obvious faults and flaws in logic and in reality.

Actually, the public blockchain is a very good analogy for gold. Both derive their value from a public consensus endorsement through repeated shared experience.

In gold's case, it has a public "address" in the periodic table and the physical manifestation of that address is exposed to repeated validation by the whole of society over centuries.

An obscured blockchain can never achieve that level of network effect because......obscured LoL !  :P

One holder sees one address. Another holder sees another address and non-holders see nothing at all. No shared experience. No shared consensus. No shared value.

It works for backed money (e.g. fiat transport & CT sidechains). But as unbacked money is about as effective as a chocolate teapot.

The thing with gold is that it's one of the best money laundering assets.

You can buy an acre in a gold mining area and then "make-appear" 100kg of gold that you ..."mined" from your ground.

And voila. Now you have 100kg x 40k $ = 4mn USD... all "mined" out of "the ground". Or so you say.

So if you have black money => you buy gold => you pretend that you mined it => you legalized your black money.

Gold is one of the very few cases that you can make money appear out of nowhere, in terms of accounting. That's a very useful - even irreplaceable quality. Most other types of assets or currencies have a trail.

The scale is totally different. CC can be mined by an individual who doesn't have to document how they paid their electrical bill. A producing gold mine is not cheap, and then it is also probably possible to forensically detect if the worthwhile scale of mined gold had been physically extracted. And the scale makes it perhaps worth investigating/prosecuting.

I know it's not my business but it seems like Monero guys create random threads against DASH and then fill it with random stuff; Like TechorMarketing to me looks like a Monero hate thread starter by the same group who attack other coins with no development to talk about in their part. I come to this thread because I remember this
Ethereum's 'Casper' system designer Vlad Zamfir - DASH centralized governance masternode model is a failure.

Listen to his comments in this video and discuss

https://www.youtube.com/watch?v=StMBdBfwn8c&feature=youtu.be&t=1381

Ethereum's 'Casper' will be designed to avoid the catastrophic problems of the DASH design

I created this account just so these Monero drama queens stop putting shit on other people mouth, we know you hate DASH that much but at least quote Blad Zamfir right you piece of shit.

We don't need you're garbage drama and false quoting Vlad.

Checking he's history now I've seen that he did this before as well only against Dash and it is not surprising since Monero/Aeon developer himself started hate threads and then comes the shills right after it continuing talking random things up against Dash. It's pretty pathetic to be honest

P.S I think TechorMarketing deleted he's thread after getting to much heat https://bitcointalk.org/index.php?topic=1400334.msg14215301#msg14215301 ??

Cryptographers (using the laws of mathematics) decide what is bad crypto.

EG:

Quote
Peter Todd calls DASH "snake oil" and bad crypto:

* bad crypto: https://twitter.com/petertoddbtc/status/622081863008436225
 
gmaxwell calls DASH harmful garbage and dysfunctional software:
* https://bitcointalk.org/index.php?topic=1001642.msg10922949#msg10922949

The Todd also called Monero "good crypto" so that coin is off-topic on this thread.

How quickly Alex forgets--must have dementia or something.  ???

I never asked for NSA proof transactions, nor was I promised them, but I would like protection from non-state actors, and if the right network evolves within I2p or TOR or something else, then a coin that can be NSA proof would be even better, so no dash, yes Monero.

What part of "untraceable" and "nobody" don't you get?

..."nobody can trace your transfers unless you decide so"

Yeah, well, I didn't decide that I wanted the government to know what I'm transacting :'(

Monero #SCAM #REKT  :'( :'( :'(
XMR #snakeoil  :'( :'( :'(

Again, you're conflating metadata that requires your OSPEC to be on point and the network you are interacting with not to leek information with Monero's technology--so this is like blaming a car company for traffic accidents caused by the absence of a stop sign. The car company can only do so much, but in dash's case they forgot the airbags and brakes.




Against the NSA yes I stand by the assertion that IP address correlation unmasks, overlapping rings unmask, etc. It all adds up if you are trying to hide from governments, then I don't trust Monero or any anonymous coin. Notice I wrote "privacy" and not anonymity in prior post upthread. For privacy, I think Monero is suitable and Dash is not (because not autonomous End-to-End).

And if CT is ever implemented for bitcoin itself then bitcoin will no longer be a tier 1 asset and no longer constitute viable money. (At least not in any sociological sense that could support its value).

Just for clarification, by "monetary tier", I meant this: If I use my bike as "money" to pay for something then the bike is the tier 1 money and the contract that says someone owns it is the tier 2 asset. The tier 2 asset can be obscured, burned, washed through the washing machine, without compromising the integrity or value of the tier 1 asset.

In crypto, obscured blockchains (such as CT) potentially have the job of record keeping and obscuring the ownership of a tier 1 asset (bitcoin). But they are not tier 1 assets in their own right (by virtue of being obscured).

https://i.imgur.com/gEOPCxP.png

https://i.imgur.com/CIrV7MI.png

I have to say that I like this (totally flawed) argument  ;D because it seems to be convincing at first.  

However, it is flawed for two reasons: one economical, and one of principle.

The thing with any crypto currency, even bitcoin, is that there IS NO FIRST TIER.  There are no "individual bitcoins as entities existing somewhere", there are only proofs that you ARE ENTITLED TO SPEND an amount of bitcoin.

After all, what happens is that "bitcoins" are UTXO of which you can "solve the puzzle" (of which you have the private key that can easily solve the puzzle).  When you have transacted an UTXO, that specific UTXO doesn't exist any more (it is not "unspend" any more).  You've created a NEW UTXO and you've destroyed an old one.  So each transaction is a "next tier" according to the logic you introduced.

In a certain limit, you may say that "real" bitcoins are the UTXO of the coinbase, when a miner makes a new block.  Now, when that miner transfers those coins to someone, he's in fact not transferring that UTXO (he could if he were to *transfer the secret key* but that would be silly to accept).  He's giving you a new UTXO, that proves that you are now entitled to spend those bitcoins, and he's not any more.  But no actual bitcoin, no actual "bike" has changed hand: a new document has been written, a new notarial act, that tells everybody that the "bike" is now your property.

However, in as much as new UTXO are of exactly the same form as the coinbase ones, you could even say that the coinbase UTXO is already a "tier 2" act of proof of possession, and that there are no bitcoins like there is your bike: there are only successive proofs of possession, which are the successive UTXO.

Next, we come to multiple-input-multiple-output transactions on bitcoin.  There too, your argument breaks down.  If bitcoin number 57 (what's that ?  That's the non-existent equivalent of your tier-1 bike) and bitcoin number 102 are both inputs to transaction 20370 on the chain, and there is an output of 1 bitcoin, and another output of 1 bitcoin, which one is which ?  Is the owner of the first output now the owner of bitcoin number 57 (the red bike) or is he now owner of bitcoin number 102 (the green bike) ?

So even on a public block chain there's no such thing as "tier-1 possession" because these objects don't exist: the only thing that exist is PROOF OF RIGHT TO SPEND (your "tier-2" kind of stuff).

And now we come to something essential which is the economic argument: in order for a monetary unit to be fungible, the ONLY thing that should be knowable is the proof of right to spend.  That's in fact exactly the same with fiat money in a bank account.  When you pay someone, the only thing that is verified is that you have the right to spend so many dollars, and not whether those dollars are representing the green or the red bike.  That's called "fungible units".

The only thing that is needed in a payment system is a proof of right to spend.  Public block chains fail at that, because they give out MORE information than just that.  Obfuscated block chains are a better approach to that ideal.

There is no "first tier" in a monetary unit.

How much money was lost as a result of the DASH paper wallet faulty RNG.


Recently, Dash presented a significant appreciation in its price and it is believed that the main reason is the launch of "Dash Text" in Venezuela, an SMS-based crypto-currency transaction service. According to the company, the application eliminates the need for Venezuelan users to have smartphones and internet access to carry out transactions involving crypto-coins, a fact that has historically been a significant barrier to the adoption of crypto-coins in the country led by Nicolás Maduro.

The solution to this problem was built in partnership with BlockCypher, specializing in blockchain solutions that allow users to interact with multiple crypto-coins through a single platform. Currently in the beta version, Dash Text will allow Movistar and Digitel users - Venezuela's largest telecommunications providers - to access Dash services through a simple five-digit shortcode.
