Where exactly is the "spyware" aspect of DASH located?

It's an open source project, so please, if possible, name of file and line of code...

Here is what I wrote:

I claim that Dash is spyware because the anonymity is trusted to masternodes which are an obvious target for the NSA or anyone who can profit on breaking anonymity (e.g. those who want to blackmail you or whatever).

I don't need to dig in the source. It is a conceptual truth in terms of the way the anonymity has been described (at least the last time I paid attention).

Evan mentioned he was going to improve it for Evolution, but even if he shifts to onion routing across masternodes, that won't entirely absolve the attacks on anonymity from colluding masternodes (although it can improve the statistics on the masternode coverage needed for breaking anonymity). Ditto any mixnet he employs, including if he prefers to implement CoinShuffle.

Instead if he implements Cryptonote then he won't have RingCT's features. If implements RingCT, then he is copying Monero's recent research. Also I doubt he is capable of understanding the RingCT white paper and implementing it. He will probably have to work by copying source code or hiring some expert crypto assistance.

In any case, that won't correct the other flaws in InstantX and mass-scale transactions that are his other big selling points of Evolution. And none of that will correct the fact that masternodes reduces Dash to an inferior proof-of-stake security/politics model.

I will correct the comparison chart to indicate the anonymity may be improving for Evolution.

OK, I missed that (just got to the thread), but Spyware, as a term, is something entirely different.

It's one thing to say that an obfuscation model could be vulnerable under XYZ circumstances with a probability of x% of that happening, and another thing altogether to say "spyware". This is sensationalist crap. Especially when the masternode model as is implemented right now can use multiple rounds of laundering where each round reduces the probability of that happening to an insanely low percentage.

Sybil attacks with those you are mixing with is a very overlooked -yet much weaker point- than masternodes being crooked. Pretending to be a mixing partner does not require NSA-level resources. Unfortunately, all mixing systems will have this problem to one degree or the other.

I disagree with the probability miscalculation that says many mixers assures the probability of unmasking is reduced asymptotically towards 0. There are patterns that develop and can be correlated. The more visibility, the more correlation. For me to enumerate all scenarios would require writing a research paper.

When all the masternodes are hosted, it is not crap to say the NSA can probably get access trivially. When most are hosted on one cloud provider (something I read, don't know if it is true), then even an employee could potentially get access trivially.

You simply can't get anonymity without cryptography. The masternodes see everything in clear text. Dash is more likely to be spyware than anonymity. In fact, I've conjectured the wild speculation that Evan hasn't been worried about SEC because he might be on the dole of the NSA (but that is too conspiratorial to assert as likely).

Dark my ass. Dark where the NSA got its fist up the users' buttholes. I have often returned to the wild speculation that Dark(Vader)Coin was really a big data harvesting coin.

The official definition of spyware is any software that exposes your data out on the wire. It doesn't have to actually be intended to do that. Just opening the security hole is sufficient to meet the definition.

It's your table / your labels / your definitions so I don't mind really. I just needed some clarification because it was stated as fact that dash is ...spyware.

I already updated the table to link to our discussion and added "potentially improving". So hopefully it is clear to readers that the characterization is contested to some degree.

I somewhat agree with you that "spyware" is a bit harsh and doesn't imply that the mixing might work in some scenarios, except in another sense I think it is unfair if I don't draw attention to the fact that it can be the opposite of anonymity and actually increase the odds of intercepting user data in clear text in certain attack scenarios. For example, it provides prefiltered list of those who are attempting to be anonymous— which is one example of why multiple rounds won't help in some scenarios of "privacy".

Feel free to try and attack a PoS chain and let me know how successful you are.

That happens all the time.  PoS coins have to use (increasingly convoluted) checkpoint schemes to fight 'nothing-at-stake' type attacks.

NovaCoin, for example, just got #rekt by one.  And Balthazar is 100 times smarter and better at coding than Dash's trash developer.

It would be such a terrible tragedy if Dash suffered catastrophic consensus failure about an hour before Madoffield's Miami talk starts...  Grin

I have linked to this post in my comparison table for the BitShares column of the Research row.

That's nice, but you're largely discrediting the R&D Bitshares and other cryptocurrencies have done.

I've now separated the Research and Development into two rows on the comparison table upthread. I am recognizing the significant Development work done on all those coins.

As for the Research row of the table, I am definitely asserting that Dash's research is abysmal. Recent more detailed study on InstantX has further convinced me of my long-held "helicopter view" intuitions.

As for BitShares, let's discuss more below and I will adjust my perspective as necessary.

Afaics BitShares has introduced inferior systems such as DPOS which suffer from the flawed security model of Proof-of-Stake. They do some reasonably high-level tech (Daniel is smart dude) but afaics their focus has been incorrect. I remain somewhat opened-minded to BitShares, because at least Daniel is smart.

Crap like BitUSD failed afaik. As what I remember, many of Daniel's ideas have been not very well thought out. Nevertheless he is a smart dude, so I don't entirely ignore BitShares (unlike Dash which I totally ignored for the past year until they announced Evolution which purports to compete with my design, so then I had to investigate more closely).

You PoW zealots love to harp on PoS as being insecure, yet there has only ever been one successful attack on a PoS coin (and it was one that is dying with little community support- similar to how numerous PoW coins with low hash rate have been successfully attacked.) dPoS also allows for many great features.. it is the backbone for SmartAssets, Hire-able employees, high scalability, etc..

I can do all those features better than DPOS and with PoW. The insecurity of PoS has been explained in the prior couple of posts.

bitUSD has not failed- look at a historic graph and it has held its peg quite well. It did not work as it was originally designed, but it certainly works. You (wrongly) think you are omniscient and know what features are important for a cryptocurrency to succeed, and thus disregard all innovations Bitshares has invented/implemented as useless. At least I can admit when I am wrong or when I am speculating.

Before you posted, I had already edited my post as follows (to replace the underlined portion you quoted):


At least the original design for BitUSD failed afaik. Which is what I told him when he was proposing it.


I haven't had time to study what changes were made after the initial design was discovered to be flawed (as I told them it was back in 2013) and whether the new design works correctly.

No you are incorrect about my views. I know a peg can work by employing speculation, but it can never be lossless. I wanted to do some more work on quantifying that, but it is not high on my priority list. If BitShares has perfected the math and understanding, then kudos. But I don't assume they have without studying it. And I haven't had the time to study their latest design iteration on BitUSD. You know there is so much garbage released in altcoin land, nobody has enough time to study every shred of it in detail.


The above is not useless in my view, but devil is in the details on assets and programmable block chains, so I can't access that until I am ready to do a deep study. Their work may be trivial or deep. I do not know.

Referral Program (https://bitshares.org/technology/referral-rewards-program/)
Bridges/Gateways (built-in to the wallet)
Hire-able Employees (self-funding development, advertising, etc..) (due to dPoS)
Fee-backed assets (in development/conceptual phase)

I recently tested the waters a bit on that structure to see if it could really motivate me to work on a new feature for them. I discovered precisely what I am warning you about, that politics will tend to diverge not converge (should I provide a link?). I predict that chaos will reign in DPOS eventually and a dictator will have to take control. I remain somewhat open-minded, but the theory of the power-law distribution seems irrefutable.

The most scalable blockchain (that currently exists) (https://bitshares.org/technology/industrial-performance-and-scalability/)

I am smirking. Perhaps yeah on "currently exists", but don't ask me to start digging on the flaws because I will probably accidentally blow up BitShares the same as I did Dash (I didn't even plan to find that broken math in Dash, it came out of a discussion about security of my design in my thread). I don't have the time to waste on that though. Otherwise the "currently exists" will always be a valid retort.

I already blew up their claimed 1000+ TX/sec and got everyone to realize it is only about 100+ TX/sec in reality on current hardware.

An improved multi-signature transaction protocol (https://bitshares.org/technology/dynamic-account-permissions/)
Recurring and scheduled payments (https://bitshares.org/technology/recurring-and-scheduled-payments/)
Collateralized Bond Market (https://bitshares.org/technology/collateralized-bond-market/)
Stakeholder-Approved project funding (https://bitshares.org/technology/transferable-named-accounts/)
Transferable named accounts (https://bitshares.org/technology/transferable-named-accounts/)
Insurance (in a conceptual phase)

Smart contract stuff is very interesting. But I am not sure if hard-coded contracts or a programmable block chain is best.

So it is difficult for me to agree that this is research. Unless I study it and find a lot of innovation on math and sort, I will say this is a lot of obvious development that anyone would do if they were enumerating different hard-coded variants of things one could do with a more generalized programmable block chain.

I hope you realize my point is that a generalized paradigm in theory has exponentially more network effects.

So I am bumping up BitShare's development rating significantly, but I maintain their Research level is some where between average and above average. It isn't fundamental Satoshi-level research for crypto (which is the sort of research I have been attempting).

Stealth addresses + Confidential Transactions (more as to the Developmental side of R&D as these ideas were not original)

They copied that. I admit their accumulated development is quite high. And I even saw they had a contributor whip up some of that anonymity work very quickly, so it isn't just one guy on the development side. On research side, I think it is less impressive.

This is all apparently useless according to you. You must not fully understand how everything works, that it exists, and/or the implications of all the features listed.

I hope you realize now that I don't think it is entirely useless but it is rather my intuitions about priorities and scaling faster.

I think they've gone for the "I'll build every feature" approach. And I am going for the "I'll build the platform and let others build every feature" approach.

But I don't dismiss that they might get traction. We will see. As I said, I haven't entirely dismissed BitShares.

Your claim that attacking a PoS coin is a "fixed cost" and attacking a PoW coin is an "unbounded cost" is similarly ridiculous considering the costs of attacking both types are dynamic (PoS depending on the price of the coin and PoW depending on the hash power of the coin.)

It is absolutely correct. Once you control a PoS coin, you control it forever at no additional (significant) cost. How can anyone else ever take control away from you since you control staking and the only way anyone else can get stake is by buying it from you? No one can and you don't need to continue expending resources (mining) to retain control as you do with PoW.

Wrong. If someone buys up 50%+ of the currency supply to attack it, the PoS coin's community thanks them for the donation, forks the coin, rolls back the blockchain, and continues business as usual.

In that case, the system doesn't work at all, because it doesn't enforce consensus. You might as well have "the community" record everyone's holdings on a spreadsheet.

Also, attacking via 50% doesn't necessarily require "buying up" anything. It could be (at least in part) having hacked an exchange or other large holder, or having accumulated stake through borrowing. The same with PoW (compromising a large pool for example), except that it isn't permanent.

Obviously that is not an ideal solution, but a worst-case scenario solution. Feel free to try and attack a PoS chain and let me know how successful you are.

You are missing the point. The stake is an attack.

If you and few others who were Kings before but gave up majority stake, you fork but the users may not follow you. The masses tend to be very apathetic about changing what they are accustomed to.

The majority can change the protocol at-will. Ditto with Satoshi's PoW (but I claim not in my innovation), except it is an unbounded ongoing cost;whereas, with PoS it is a one-time cost. And you can even recoup that cost by shorting the coin if the manipulations will cause a drop in price, or by recouping profits gained from changing the protocol.

As long as the protocol changes don't too much inconvenience the masses, they won't bother to change. For example, adding a small transaction fee that is paid to the new Kings.

You claim we can't attack PoS, but this may be because there is no profit for us to do so, because your PoS coins have no usership nor sufficient non-mirage liquidity to profit from shorting. Go grow the usership and/or the true liquidity of the float, then observe the game theory.

You are also presuming that the majority of stake exists. Instead you may have 10 coalitions of minority stakes all fighting each other. Thus 10 forks and chaos due to being able to spend the coins 10 times.

Forking will almost always be avoided because politically it is devastating. Again the attackers can just short the coin.

A dictator attacker who unifies control (a la Napoleon) by acquiring majority stake would perhaps be cheered (ending the chaos). This is the strategy being deployed right now before our eyes to bring the world to its knees to beg for a NWO one world government to stop the nation-state chaos. The banksters created that chaos on purpose.

"Proof-of-Stake Politics (non-decentralized governance)" - I guess you haven't been following Bitcoin lately? There are just as much politics involved with PoW as soon as a cryptocurrency is large enough. Google "Bitcoin block size limit controversy".

Perhaps you haven't noticed that changing Bitcoin's protocol is incredibly difficult because it requires convincing 50% of the mining hashrate to do so. In my design, it will require ~100%. That is zero effective politics. People can foam at the mouth but they can't actually change the protocol.

That sounds like a horrible idea... you are banking on the fact you will release the cryptocurrency without any flaws. Furthermore, it will be hard to make changes if something desperately needs to be changed. One saboteur can ruin it for everybody. If Satoshi would have made Bitcoin that way, I'm sure Bitcoin would already be dead. Cryptocurrencies need to be able to evolve easily due to unknown issues that will certainly come up in the future.

Btw, thanks for raising the point that my innovation to eliminate control-of-the-majority means hard forks become that much more difficult to accomplish. I do need to make sure I pay attention to that!

A PoW coin becomes progressively more difficult to hard fork as the mining becomes more diversified. Obviously Satoshi could—and Monero can still—hard fork, because they have loyalty of the miners because it is not yet a widely adopted block chain.

But yeah, a PoW coin needs to get their protocol correct before it becomes too widely deployed.

Also note that even widely deployed, miners are much more willing to accept a hard fork which fixes a bug for as long as it isn't injuring their vested interests.

Users invest in a protocol and if politics can change the protocol at any time in the future, then users can't trust the future. This is another reason Bitcoin can't just graft on all the innovations of altcoins. It is one of the prominent reasons I am trying to design a PoW block chain which can be hot-plugged with unlimited public block chain transaction format variants that are orthogonal to the PoW chain which remains a constant (so they don't all have to reinvent security).

Whereas, PoS proponents want absolute control forever. And thus they are private club designs. Their designs will never be ubiquitous platforms because they are not strictly protocol:

The only way you could accomplish what you stated is for the system to not enforce a consensus protocol.

---8<---

Either proof-of-stake is not a decentralized protocol for consensus so your point is correct, or vice versa so your point is incorrect. This ties into the point that politics has absolute control in proof-of-stake. Does everyone always agree with the decision of the government. Who is that again who predicted DPOS would end up in a shooting war?

The PoW proponents are trying to design the protocol that will be the block chain for the entire internet, not some private club where we get to play King forever. Inventing a protocol that is orthogonal to politics is I think part of the definition of an end-to-end principled protocol (end-to-end is an underlying principle of all popular internet protocols).

Whereas in Proof-of-Stake coins, the collectivized, centralized control is absolute.

As stated above, there is a reason why a "majority rules" system is best.

Also I assume you are ignoring the radical distinction in the security model. I will link the chart to our recent epiphany on explaining that distinction.
As stated above, there is a reason why a "majority rules" system is best. And yes, I have no idea what you are referring to when you say "radical distinction", however I've probably read about it before as I have been in and/or read a lot of PoS v PoW debates before. I have a full time job, a life, etc.. I don't have all day to spend on the forums like some people...

Bitshares R&D is average yet Monero (LOL) is above average and your vaporware is above average. Monero releases one whitepaper and all the sudden they are above average R&D... give me a break lol.

Monero cleaned up the rough edges of Cryptonote such as getting the wallets correct for the equal denominations for mixing. They were able to bring a polished CN implementation to the market. They focused on doing one thing well. Perhaps Boolberry also accomplished some of those too, but afaik zoid has become unresponsive. Although I say CN is unprovable anonymity, that is not saying it is not anonymous mixing. Tor is unprovable too, yet many people feel it aids their privacy. I saw that Dash is spyware because the anonymity is trusted to masternodes which are an obvious target for the NSA or anyone who can profit on breaking anonymity (e.g. those who want to blackmail you or whatever).

Monero has invented RingCT. That is not trivial cryptography. Even Blockstream folks were involved and impressed. Two months before they completed theirs, I (claim to have) invented a similar system ZKT (Zero Knowledge Transactions) which is based on the theoretically more compact CCT instead of Blockstream's CT. I even claim to have improved CCT to eliminate its weaknesses (e.g. the requirement for the Proof-of-Square). Simultaneously I perfected Satohi's Proof-of-Work, and the details of that are in my thread. That is something that no one else has been able to do.

So yeah, my R & D is above average, especially for only 1 dude. (and I am not even formally trained in the requisite math and cryptography, so I started with a handicap)

Afaics, Dash has invented nothing original but Dunning-Kruger flaws.
That's nice, but you're largely discrediting the R&D Bitshares and other cryptocurrencies have done.

Afaics BitShares has introduced inferior systems such as DPOS which suffer from the flawed security model of Proof-of-Stake.

At least I can admit when I am wrong or when I am speculating.

You obviously have no idea how much R&D in many different decentralized technologies Bitshares has done in its forums as a community over the past couple years. They've done way more research and development than Monero and yourself combined.

They have done a lot of ideas that seem dubious to me. Agree they are very busy and have engineering talent. But they don't seem to have focused talent. They've accomplished somethings, but nothing stands out for me as a big win yet.

If you can point out any feature that is a really a big innovation, I am interested to reconsider my thinking about BitShares?

If you sling mud atleast get your facts straight... 1 Whitepaper for Monero? What about https://lab.getmonero.org/ and https://eprint.iacr.org/2015/1098.pdf Huh So who has no Idea?
Thanks for the link, I was only aware of the Ring CT whitepaper. Still, he largely discredits all of the R&D that Bitshares has done which is rediculous and it is obvious he hasn't followed the Bitshares community closely (as it is obvious I haven't followed the Monero community closely.) Not only has Bitshares done a ton of research, but there are two words in R & D... Research and Development. Bitshares has done more development than both coins I mentioned (anonymint's vaporware and monero) combined.

Reasonable point. I will move Development to a separate row or just delete Development.

2. Bitshares is off topic on this thread. PoS isn't entirely off topic since Dash's masternodes are a form of PoS (even more so in evolution since masternodes/stake will verify transactions).

That is why I included BitShares in the same table, since we concluded recently in my thread that Dash is really proof-of-stake. And BitShares and ShadowCoin are other coins attempting to add on chain protocol level anonymity. Someone else brought up ShadowCoin, so I figured I would preempt someone bringing up BitShares and not having it already in the table.

To be fair you replied to a table that included SDC. That is also off topic on this thread. No reason to go even more off topic though.

Maybe you are correct (that I thread-jacked and you deserve to criticize me for that), but if I have to expend the effort to create a comparison chart table, then I want to do it once for every reason I might need it.

Sorry I really don't want to re-enter extended discussions, but that liar table hit a nerve.

Your very high-level conceptualizations are analogous to way Evan thinks when he is designing Dash. The flaw in your logic is you haven't even thought about the details of what it entails to accomplish what you wrote. You are broadstroking your conceptualizations without expert introspection.

The only way you could accomplish what you stated is for the system to not enforce a consensus protocol.

Your conceptualization is that you can identify who is acting in bad faith and confiscate their stake. But if you could do that in a proof-of-stake design, then it would be impossible to attack the coin at the protocol level with any level of stake. Since we we know that is not true, then it follows logically that your conceptualization is proven to be impossible. I have explained in my thread that the only way to achieve 100% permissionless security at the protocol level is with my innovation on consensus.

Either proof-of-stake is not a decentralized protocol for consensus so your point is correct, or vice versa so your point is incorrect. This ties into the point that politics has absolute control in proof-of-stake. Does everyone always agree with the decision of the government. Who is that again who predicted DPOS would end up in a shooting war?

Someone else brought up ShadowCoin, so I figured I would preempt someone bringing up BitShares and not having it already in the table.

To be fair you replied to a table that included SDC. That is also off topic on this thread. No reason to go even more off topic though.

Your claim that attacking a PoS coin is a "fixed cost" and attacking a PoW coin is an "unbounded cost" is similarly ridiculous considering the costs of attacking both types are dynamic (PoS depending on the price of the coin and PoW depending on the hash power of the coin.)

It is absolutely correct. Once you control a PoS coin, you control it forever at no additional (significant) cost. How can anyone else ever take control away from you since you control staking and the only way anyone else can get stake is by buying it from you? No one can and you don't need to continue expending resources (mining) to retain control as you do with PoW.

Wrong. If someone buys up 50%+ of the currency supply to attack it, the PoS coin's community thanks them for the donation, forks the coin, rolls back the blockchain, and continues business as usual.

In that case, the system doesn't work at all, because it doesn't enforce consensus. You might as well have "the community" record everyone's holdings on a spreadsheet.

Also, attacking via 50% doesn't necessarily require "buying up" anything. It could be (at least in part) having hacked an exchange or other large holder, or having accumulated stake through borrowing. The same with PoW (compromising a large pool for example), except that it isn't permanent.

@TPTB_need_war: Monero has a Mobile App -> https://play.google.com/store/apps/details?id=com.ionicframework.monerowallet116498&hl=nl

Not sure what the difference is between "Browser wallet" & "Browser/SPV wallet", but Monero got https://mymonero.com.

Will correct the table now. Afaics the distinction would be the wallet can be a lite (not full node) client. That was on the prior table, so I included it.

Some other points are quite subjective in my opinion.

Any besides R & D? If yes, please explain what is not objective?

2. Bitshares is off topic on this thread. PoS isn't entirely off topic since Dash's masternodes are a form of PoS (even more so in evolution since masternodes/stake will verify transactions).

That is why I included BitShares in the same table, since we concluded recently in my thread that Dash is really proof-of-stake. And BitShares and ShadowCoin are other coins attempting to add on chain protocol level anonymity.

.... AnonyMint pumping his vaporware as usual ...

"Proof-of-Stake Politics (non-decentralized governance)" - I guess you haven't been following Bitcoin lately? There are just as much politics involved with PoW as soon as a cryptocurrency is large enough. Google "Bitcoin block size limit controversy".

Bitshares R&D is average yet Monero (LOL) is above average and your vaporware is above average. Monero releases one whitepaper and all the sudden they are above average R&D... give me a break lol. You obviously have no idea how much R&D in many different decentralized technologies Bitshares

1. Monero has released many more than one "white paper". There is one formal research paper (ringCT) but at least 4 other MRL reports and some other documents.

2. Bitshares is off topic on this thread. PoS isn't entirely off topic since Dash's masternodes are a form of PoS (even more so in evolution since masternodes/stake will verify transactions).

How can I be pumping that which will not be mineable nor available in an IPO?

Explain that genius.  Wink

So... it will not be trade-able on the open market either, genius?  Wink

Not likely during the launch phase (not in any significant volume). As was covered in detail in a discussion in my thread. Nuanced issues fly over the head of people who think they know everything.
