Come on, I used "car" to suggest a sizable amount.  Replace it with "plane tickets" or "home theater" or whatever if you wish.

But isn't bitcoin supposed to be used to pay for everyting through the internet, from chewing gum to a mansion in Bali?  

(And if you buy a gold-plated Rolls Royce from a reputable dealer 1000 miles away, why would he not deliver it to your home -- after he got your check and cashed it?)

A couple of weeks ago, some famous bitcoin guru (Matonis?) explained in an article how in the future one would walk into a car dealership, choose a model,  point the smartphone to the QR code on the windscreen, and drive out, without interacting with a single person.  He did not mention satoshi-testing, air gap, brainwallet -- or what the client would to if the sticker on the windscreen turned out to be fake.


I fail to see why you think that applications built on top of the Bitcoin network are fundamentally any less secure as a payment method than applications built on top of the legacy banking system.

(For a response to the following argument, leave Matonis or any other Bitcoin proselytizer aside for now, please. I don't enjoy arguing strawmen.)

The Bitcoin applications and their security can (and will eventually) exhibit the same amount of security (or lack thereof) as those tied in with the banking system. That part is obvious, because the Bitcoin protocol doesn't address the security of this layer in any way.

EDIT: I should say "reach at least the level of security of applications on top of the banking system", because of the possibility to built Bitcoin applications as open-source applications, which seems to have a better track record wrt security compared to closed source applications.


What is fundamentally different is the security of the underlying transfer mechanism itself. In the case of the legacy banking system, built on central authority, it allows high-level interference if conflict resolution is required. In the case of Bitcoin, no such interference is possible, because the decentralized consensus cannot be changed by any individual (or any group below ~50% of network computing power).

So, to summarize: the only additional security that comes from applications on top of the banking system are

a) better, more secure, more intuitive applications - which is not a fundamental problem, and will be solved over time, with more time and ressources being invested in creating them. Go check out electrum in the meantime, to see what an already pretty good application looks like.

b) security through central authority revisions - this part is by design, and it is not at all obvious to me that the positive effects (justified execution of central authority) outweight the negative effects (unjustified execution of central authority). We probably won't be able to answer this question without reference to some principles that we do agree or do not agree on, but I am pretty sure that any case of justified execution of central authority in finance you can bring forward, I or someone else will be able to counter with a case of abuse of such power.

Wow this is not good Sad

No, it certainly is not. I especially don't like the implications for future GABI and COIN impact.

(I know, they're not the same type of investment vehicle, but I'm not sure either if they're different enough to make a completely different buying behavior likely at the moment).

I remain long-term bullish, but I am also starting to get myself used to the idea that we could be in for a substantially longer bear market, to the order of another year, of no substantial and lasting price increase.

Boolberry is now freaking suspicious, not only it has been pumped to top of polonix volume but the attack coincided with this.

No. No fucking way. Let's stop those insinuations right here!

There is no evidence that BBR has anything to do this, and you're doing XMR a huge disservice by implying this.

In addition, you completely lose the right to complain about anti-Monero FUD if you spread FUD yourself.

If you have any hard evidence, present it. If you don't, stop spreading FUD. It's really that simple.

While I agree with you, you must admit that the trolls and hacks have created an environment of suspicion, and it is natural that the anonymous dev, for whom there is in fact a fair body of circumstantial evidence of participation in the original cryptonote implementation, should attract that suspicion.  I'm hoping that CZ will dispell some of the FUD around BBR.  If people frankly voice their concerns, they may be dispelled more promptly.  You help by rightly observing there is a lack of material evidence for this specific suspicion, but the factors which allow suspicion to fester in the background remain, and getting them aired out may disinfect.




> but the factors which allow suspicion to fester in the background remain

Seems to be a CN thing then... It's not as if, to the outside observer, XMR looks immaculate (de-optimized initial mining, rather unintuitive emission curve if the goal is a broad adoption).

So, splinters, brother's eyes, etc. ... I'd rather we don't go there. If there's a valid question about the competition, let's raise it (and we do so plenty enough in here). But speculative accusations serve no purpose other than to create bad blood in something that could be, in the longer term, a collaborative effort.
1244  Economy / Speculation / Re: rpietila Calling the Bottom on: September 04, 2014, 07:46:24 PM
Dont get me wront. Bitcoin would have been a really cool thing. Well, if it had come *before* Paypal etc.. We already have an online payment system.
Costing a whole lot more (3% of the sale plus ~30 cent fixed vs. ~5 cent),
Actually i would argue it costs PayPal less, but they charge more.
Bitpay basicly has the same expenses as Paypal. While the transactions cost less with BTC all the other expenses need to be covered as well, just like Paypal that includes servers, staff etc..
Paypal is highly profitable, Bitpay, who knows. Maybe they are still burning though venture capital.
And thats excluding the other costs, fees to aquire BTC, miners not actually getting payed for signing the transaction instead getting the lions share from block rewards. Sure, its still a long while to go until block rewards are so low that the hashing power securing the network gets so low a 51% attack is almost trivial. My guess would be that miners will revolt and demand higher transaction fees long before than.

and being a nightmare for merchants because of conflict resolution by default going in favor of the customer.
And thats excactly the reason why customers arent adopting BTC on a large scale. Why would you want to give up customer protection?

I answered that in the posts afterwards: because merchants have a strong incentive to convince customers to pay in BTC. So most likely: they will give rebates / other benefits to BTC paying customers to encourage a payment vector that increases their margin by ~3% (or maybe closer to 2% after the rebates).

EDIT: Up to OP to decide if the off-topicness should end here. I enjoy the tangentials, but understand also the desire to keep the discussion centered around the original post.

I agree that most economists consider inflationary currency optimal.  I suppose, in a sense, that makes them the orthodoxy.  "Orthodoxy" sounds a bit odd to me.  In my mind the word is linked with religious orthodoxy--inflexibility, unwillingness to adapt, resistance to new ideas--"crusty."
Your usage makes Evolutionary biology today's orthodoxy, and Creationism ...what?  More of a feelsy peeve than an objection.

If economics ("economics" here being the field that guides - some of - a state's decisions on how to optimize its economic output) is ever pursued with the same rigor as biology, I will share that feelsy peeve :D (sorry, potshot, I know.)

Bitcoin is already an amazing experiment.  No way to overstate this.
Re. "[is] economical development ... impossible with a deflationary currency":  It's not a binary thing (just stressing this, I doubt you meant to say it was).
Better questions:
Is deflationary currency optimal for economic growth?
Is the type of economic growth likely to happen with deflationary currency optimal for society?
Is economic growth a prerequisite or even a measure of society's worth/wellbeing?

You're asking exactly the questions that I want to see answered as well. No disagreement here. Just that I'm happy to have them empirically answered, even if there's a risk that the outcome will be negative.


The point is for many companies, initial savings of going with *nix (initial cost being nothing) are countered by higher overheads of using it.
If I'm paying my guy $70/hr to do X, and it takes him a few minutes less to do it on a winbox, I recoup the licence cost in a day.  This does not mean that my company won't be using Linux, but it won't replace Windows.  I'd love to maximize profit, but going with freeware/shareware to the exclusion of rapeware isn't the way to do it.*

True. Which is why I consider it a completely plausible scenario that Bitcoin will never reach the "end user" in scale (like Linux in the OS market), but will be the/a backbone of our entire financial infrastructure (like Linux is for servers).

I agree that the C in the codebase in insane and dangerous. In the least, we need to refactor to C++ and comment the code.


Whatever works.

But:

"glad to hear the devs had the same idea" sounds more like you were? are? considering changing the codebase entirely.

There is no plan to replace the codebase entirely. We are open to input and considering ideas. Two very different things.


Thanks for the answers to my questions. I have nothing to add.

I would have thought that Peter Todd (previously a core bitcoin dev) would have enough on his plate as he recently (few weeks ago) joined the Viacoin dev team.

We had already talked to Peter about consulting for us before that. He does various consulting work, especially open source projects. He explained on reddit (go find it if you care) that one of his consulting clients happens to be Viacoin, and he didn't even know much about what they are doing. In typical pump-and-dump fashion, Viacoin quickly turned that consulting gig into him being their "chief scientist" and promptly put out a slicked up press release about it.

In short you are reading too much into it, and for what its worth we won't be wasting any of our donation money writing press releases and trying to promote a consulting gig as something more than what it is.



Alright, makes sense. That's not really the question that's on my mind though.

The abrasive style aside (I can even see some virtue in that), this...

If even expert bitcoiners can have their coins stolen by hackers, imagine having millions of non-tech-savy users, each with thousands of dollars worth of bitcoin in their wallets on windows machines.  Hardware wallets like Trezor can help, but there are dozens of ways of getting around them.

Hmmm... I like Klee, good guy. But I wouldn't call him an "expert Bitcoiner". Not after he left his password and/or seed, in cleartext, in his dropbox Cheesy

Seriously though, no Schadenfreude here. Just pointing out, this was so far removed from best security practices, I simply have to call bullshit on the implication that if this can't keep your coins save, nothing can. It'd be a bit like saying "If not locking your door, going on vacation for 2 months, and advertising on the local newspaper that your door is unlocked and you're on vacation doesn't prevent burglary, what could possibly do?!"
1252  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: September 04, 2014, 03:34:04 PM
What could have caused this spike, a single whale buying?

I honestly think we broke upward because we were scraping the bottom at around $470.  The last bottom we were scraping for a while was $420, and that was all the way back in May.  So my thinking is the "floor" has rising about $40-50 since then.

Don't quote me on it though, as bitcoin is full of surprises.

Agreed. Most likely technical (failure to break through previous low, high stability for the past 3-4 days, decent buying pressure on stamp), maybe triggered today by news (ECB decision) - but if so, it's probably more of a trigger than a reason.

Now, whether this is the turning point is another thing, entirely. Daily close above $500, and we can start talking about that possibility. Cheesy
1253  Economy / Speculation / Re: rpietila Calling the Bottom on: September 04, 2014, 03:27:48 PM
Not to mention that, in terms of divisibility, until digital currencies came along, with decimal places that could be extended out, a deflationary currency wasn't practically implementable past a certain point. Physical currencies can only be split so much into smaller units, printed, and distributed, to maintain liquidity.

Excellent point. This might not capture 100% of the "hoarding" / deferred spending problem economists like Krugman like to throw at fixed supply models, but it probably accounts for a substantial part of it. If you can spend an appropriately small fraction of something extremely valuable you are at the very least more likely to do so than someone who fears overspending, because of insufficient (and possibly intransparent) divisibility.
1254  Economy / Speculation / Re: rpietila Calling the Bottom on: September 04, 2014, 03:03:47 PM
..."OMG, a deflationary currency can NEVER work!" argument...

I don't think you're presenting the argument against deflationary currencies in the best light [smiley].  It is an argument that predates Bitcoin by at least a century, and one at the root of *every economy on Earth.*  Not just the orthodoxy.  At least what I know of it has nothing to do with tx fees.

Quote
...tx fees after emission is done will gravitate towards: total cost of running network * share of current transaction of total transactions on network, plus a small premium to make it worth miners time and effort. I don't see this as ever being more costly than current commercial payment providers, similarly to how there is no cheaper operating system than, say, Linux.

Considering that today's cost of running the network is around the value of all the coins mined, I see no reason to make this assumption.

Re. "no cheaper operating system than, say, Linux":  Why do you suppose major corporations use Windoze?  Stupid?  Like Bill?  Don't care about profits?

Maybe I didn't phrase that all too clear: I lumped together those two issues (tx fees post-emission, deflationary currency) to make the point that several contentious issues will only arise in reality well into the future, potentially giving us time to adapt / get used to them.

re: deflationary currency. Don't be mistaken, I'm not brushing aside the complexities of the issue. I do however claim that, current economical orthodoxy considers central bank guided inflationary currencies the de facto optimum. Agreed with that statement? Not that they're optimal, but that the vast majority of economists seem to consider fixed supply currencies broken beyond repair.

My point is not that a deflationary currency is necessarily better (sorry PMers), but that it will be an interesting experiment in about 100 years from now to see if modern economical development is really impossible with a deflationary currency (if Bitcoin does indeed become a major factor in global finance in the future).

re: Linux. Wasn't the point who is using it. We were talking price. (and I'm sure you know this, but while consumers barely use Linux, the Internet infrastructure relies heavily on it.)

Back on topic:

Thanks, tacotime, smooth, fluffypony for keeping us update in realtime. This is precisely the emergency response I was hoping for.

Two questions:

1) Can you already rule out that the same (or similar) attack can be mounted again?

2) Can you already rule out conclusively that no lasting damage was done (as in: according to the pre-attack ownership situation)? Any chance that some subtle damage was done that'll be discovered only later?
1256  Economy / Speculation / Re: rpietila Calling the Bottom on: September 04, 2014, 01:39:41 PM
...
Note however that I talked about "transaction costs", which for traditional payment systems are carried by the vendor/merchant. And from their side, it does stand as 3% + 30 cent (Paypal), 2% (Visa, but only if you're big enough) vs. 0 cost (if Bitcoin is used natively and the sender pays the tx fee).
...

This is a bit of a tangent, but might be interesting.  Was interesting to me when I first read it, wish I could give credit, but can't remember who pointed this out.[/sheepish disclaimer]

Bitcoin transaction costs are currently sponsored by Bitcoin inflation, which [now] is quite a bit higher than 3%.  Once all the coins are mined, and miners no longer profit through mining coin, I think it's reasonable to assume that tx fees would go up substantially (along with a bunch of other untidiness that I don't like to think about Cheesy)

Right. I'm highly skeptical towards statements made today that claim that tx fees will always be negligible.

I will however also note the following: together with the "OMG, a deflationary currency can NEVER work!" argument, the 'tx fees after emission is over' concern is placed pretty far into the future (~2140 to be precise).

You can call my reference to this short-sighted, but I think it is just another example of Satoshi's economic brilliance: some of the less palatable elements from a perspective of current economical orthodoxy are coming into existence only far enough into the future that the orthodoxy has a chance to change by then.

A bit more technical, a bit less flippant: ultimately, tx fees after emission is done will gravitate towards: total cost of running network * share of current transaction of total transactions on network, plus a small premium to make it worth miners time and effort. I don't see this as ever being more costly than current commercial payment providers, similarly to how there is no cheaper operating system than, say, Linux.
1257  Economy / Speculation / Re: rpietila Calling the Bottom on: September 04, 2014, 01:29:13 PM
As for the costs of acquiring Bitcoins for the consumer: I agree, it's far from ideal currently. However, you can send money to Bitstamp (free of charge, SEPA), buy coins at market for a fee of between 0.2% and 0.5%, and withdraw those coins free of charge.
Can't he use SEPA to pay the merchant? (Honest question, I don't know the answer.)

I understood that Dell accepts payment by check or bank transfer for orders placed by mobile or e-mail.  Not clear why this restriction, or whether it is a restriction: do they say that because no client would use those slow means if they can pay "instantaneously" by credit card?

Some companies allow this (at least in Europe), some prefer other payment providers, probably because of conflict resolution / protection from charge backs. Don't underestimate how much merchants are willing to pay to be protected from the hassle of having to deal with (fraudulent or justified, doesn't matter) reversal of payments. Visa has charge back as well of course, but in my experience, they're rather thorough and don't automatically side with the payer against the payee.

Bitcoin transfers turn it around, the merchant is now firmly favored: no costs, no way to reverse the transaction. Which means that, a) the merchant hopes to get some "easy" revenue from old coin holders / early adopters, at little cost and risk (your hypothesis, as far as I know), or b) the merchant eventually will have to offer additional benefits to customers paying in Bitcoin to compensate for the loss of customer protection that customers enjoy using traditional payment methods.
1258  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: September 04, 2014, 01:18:16 PM
Now I realize what was the reason for the mid-move turn back at 510 and the quite strong selling towards 400, which was not supported by fundamentals or anything.

The attackers have taken a short position during the decline (causing the decline), and when they run out of coins, the price also stopped declining. When it started going up, it was the time to attack.

Now if the holders sell their coins so that the price drops to below 400, without corresponding buyers except the attackers, then the attackers have won financially, fleecing the community. (The community has also won, because the bug was fixed and attack repelled.)

I pledge 1000 XMR to the devs for their ongoing good work, and BTC100 will be used to buy moneros in the exchange without further warning if I deem that the scamattackers are about to get too fat a profit from their attack.

I will use another ~BTC10 to buy XMR once the time has come (/ trading continues).


I'll put at least 5 BTC on the table for buying and I'll donate at least 25 XMR when problem is solved to the devs.

What's the dev's position on crowdfunding / public contributions / etc.? I think I remember some statement by fluffypony that he's not a big fan of bounties, as they encourage sloppy coding practices, but maybe I'm mistaken. Plus bounty =/= donations, I guess.

Is there a collective address that doesn't go to one dev alone, but is the publicly know default "Monero development donation" address? I'd be willing to contribute to that.


EDIT: Nevermind, found "Donations for general development" on page 1. Sorry for the lazyness Cheesy

Who's in control of that address? How are the proceeds split up?

well retarded was the wrong word, you are right.

the point is to make this move rational, you need assumptions that this works out as intended. if I had put the orderbook down to 34, I think it would not have worked.

Completely agreement. You would have most likely created your own bottom to sell at. (Again, unless a fix takes longer than we expect, and price reflect that uncertainty and forms new lows when trading resumes. Not that I expect it, but it's a possibility.)
