You're projected to mine $6.56 worth of BTC per month.  I'd put that on the side of "not worth it".

...Sign a message with any one of the addresses from which your funds were supposedly stolen.
How does one even do that?
I'm not sure that it's possible in blockchain.info, but in the QT client, there's a button that says "sign message" or something like that.

No, there's no existing alternative. No, the alternatives you cite won't work. There are good reasons we're pursuing the path we are.

A little more helpfully, the threat model we're working towards is a completely malware compromised computer, in which the attacker has unlimited skill and control over the machine. This is a very strong threat model. In fact, it's one so strong that no existing financial system has ever managed to survive it. Even European banks that use hardware second factors aren't really resistant to this scenario because the devices they use have extremely limited I/O bandwidth (you have to manually type in codes) so it's possible for a virus author to rewrite IBAN codes to different ones and get you to sign a wire transfer to the wrong place.

In practice such viruses don't seem to crop up because wire transfers are very rare in the current banking system (they're extremely slow, awkward, expensive etc), so the banks don't have much incentive to fix it. Credit cards don't even try and survive this threat model, they just leak money all over the place. In person debit card transactions have secure hardware but assume a trusted merchant (they're not peer to peer).

So we're being very ambitious with this effort but it's the only approach that will put us on sure footing, long term.

I think you can see why the solutions you've proposed won't work given a malware compromised host. You really need the wallet to be controlled by a device that is secure, and the only known way to make such a thing is to severely limit its abilities. So, eg, smartphones can help a bit because they have more secure operating systems than desktops, but their huge abilities make it hard to secure them and lots of people have insecure smartphones as a result. A Trezor + authenticated payments s really the best possible solution.
I see your point.  Sure, some methods might defend against some types of malware attacks, but what is the use of allowing the user to trust in those defenses if they cannot defend against all malware attacks?  It would simply give the defense method (and Bitcoin) a bad name.
984  Bitcoin / Project Development / Re: 2FA for Bitcoin-QT? on: April 26, 2013, 05:56:34 PM
See - payment protocol, Trezor.

2FA for desktop wallets is a project that has been in progress for many months now. And things are coming together nicely, but it's still nowhere near ready for launch yet.
Yes, I have read about that.  Very cool project!

I suppose my question is more along the lines of:
- Is there currently ANY 2FA for any of the installable wallets?
- Should we be looking at more than just a hardware wallet for 2FA?  Would a Yubikey be possible to use?  Email confirmation code?  Etc?

As an end user, I like having options, so I want to discuss/explore what options might be possible to implement.
985  Bitcoin / Project Development / 2FA for Bitcoin-QT? on: April 26, 2013, 05:35:36 PM
Just curious... Bitcoin-QT has a password, sure, but what if you have a keylogger on your computer?  Is there any sort of 2FA available that works with Bitcoin-QT (or any of the other installable wallets)?  Or can we brainstorm ways to support 2FA that wouldn't be hackable via the same method (i.e., would defeat keyloggers)?  Yubikey support?  Hardware signatures?  Email confirmation codes?  Etc?

If this auction doesn't go anywhere, I'll be forced to put it on eBay.  Don't make me put it on eBay, people!

It's too bad that stolen bitcoins cannot be redflagged so they can't be spent or sold on exchanges. If every bitcoins previous chain of owners can be verified it shouldn't be too hard.
It wouldn't be hard, but part of Bitcoins being Bitcoins is that they are fungible.  We'd be in for a whole huge mess if people started attempting to determine whether coins were stolen.  What authority do you go by?  If one person says funds are stolen, and another person says they were legitimately acquired, who do you believe?  What if you do not have services available to check the stolen-ness of coins prior to accepting them?  Not to mention, a proper criminal could simply send the coins to a mixing service, and then the taint would be spread across many different people and addresses.

This has been discussed many times before, and always ends up that no one wants to uphold any kind of taint on Bitcoin coins.  It just wouldn't work, and would largely kill Bitcoin.

Very cool idea (esp. the custom service) and great promotion.  I don't know if you are interested, but since you likely have hardware setup just for this purpose, you might want to try some of the bounties (although I think the math is off in some cases) - https://vanitypool.appspot.com/availableWork - although honestly I think most of those would likely take some time (lol I tried "1Casascius" across 4x Quad-Core Xeon 3.5 GHz processors at work... the best it could tell me is that there was a 50% chance that I would find a working key within a year... I think I let it run for 4 hours before I shut it off... who knows, I could have found a key if I had let it run for 4 hours and 1 minute =p).

Oh also registered =).
Thanks!

I've looked through those bounties before, and never really found any that were a better value than just mining by itself.

Certainly, a 9-character address would take quite a long time even with the hardware I do have!
989  Economy / Service Discussion / Re: Butterfly Labs on: April 26, 2013, 03:40:44 AM
So they have started to trickle prototype quality Jalaps, so what is going on with the rest of the product line? i.e Litte Single SC, Single SC, Minirig.
The PCBs were designed to handle 60 watts of power draw.  While they sort of work with 180 watts of power draw at the little-single levels of hashing, it would not be in the interest of BFL to release such a beast.  They need to properly redesign the PCB to withstand the new anticipated power draw.  They can create Jalepeno units with the old boards because they are only drawing 30 watts - far below what the boards were originally meant to handle.  They are only creating a few of them because they believe the board redesign will also make the units more power efficient.  They just announced that they finished the board revisions, and should hopefully be receiving the new boards in late next week.  At that point, full-bore production of all the product lines can commence.

Make sense?

Address in question is 1HHwDwxpeq4ZxRDE3TDNVfhT6jyj6Cx6nE

I don't have nearly 500 BTC.  That's what is screwed up.  Only one of the accounts on that list is from me which seems very odd given not sure how transfers from multiple separate accounts could be under one transaction. 

SgtSpike - Just went back and re-read my original post.  Don't recall asking for handouts.  Just trying to do public service.  Don't jump down my throat.

Ok, we'll run with this.

So your address is 1HHwDwxpeq4ZxRDE3TDNVfhT6jyj6Cx6nE.  What Bitcoin wallet software are you using?
991  Economy / Service Discussion / Re: Blockchain.info Unauthorized Withdraw on: April 25, 2013, 11:10:43 PM
Did you create a new wallet after the first hack?  The attacker still has access to the private keys of all the addresses from your old wallet, so you would want to immediately discontinue using that wallet, even if you did "resecure" it.

Look in the top right corner of every page for current forum time.  It is a few minutes slow.
993  Bitcoin / Bitcoin Discussion / Re: Bitcoin Hack at 6:22pm EST on: April 25, 2013, 11:07:51 PM
I don't buy it.  You just signed up for a bitcointalk.org account on 4/9/13, yet you have quite a lot more than 500 Bitcoins, and you've had a number of regular transactions since at least as far back as 9/14/12?  But on the forum, you're dabbling in microtrades of LTC and FC worth less than 1 BTC?

Nope, sorry.  You found a large recent transaction, then posted it as if it was yours.  You're looking for sympathy and free handouts.

Want to prove me wrong?  Sign a message with any one of the addresses from which your funds were supposedly stolen.


OP said that only one of the above addresses was his.  I retract my statement.
994  Bitcoin / Hardware / Re: BFL ASIC STATUS Shipped on: April 25, 2013, 08:43:34 PM

Nice "Butterfly Labs" logo on the boxes. It will make it easy for thieves to pick out the money machines.

Josh said they would ship in "neutral" brown boxes with no logos. Oh well, another one of Josh's bogus messages ...

I'm looking forward to the next couple of months for the forum to be full of messages like this: "help!!!!!!!!!! my BFL shipment got lost!!!!!!!!!!!".

By your logic, video cards should be in plain brown packaging too, as they are also money machines.

The merit to plain packaging, is that it protects the original box. eg. wrap it in brown paper.
*should be SHIPPED in plain brown packaging.  And they are.

I found a great address pre-generated, and I really want to use the PHYZERO code. It will not work. Sad
Sorry, use PHY99 for now... I can't get the free one to work with bitpay invoices.  Sad
998  Bitcoin / Hardware / Re: BFL's Jalapeno exists - I have one in my hand and just uploaded a video on: April 25, 2013, 07:37:25 PM

It is also worth noting that, between June 23rd and today, the price of BTC has gone up 27x while the difficulty has gone up 9x.  So, it is actually 3 times as profitable to mine today as it was back on June 23rd, 2012.  If anything, isn't that the opposite of scam?  The money-making product you bought will actually make 3 times MORE money as was projected when you first ordered it?

Look, you and I are not going to agree on the semantics of this BUT what I would ask you to think about is whether the above is reasonable to bring into the debate at all?   BFL has no control over that only over their claims of being superior and their constant claims of delivering in the fall of 2012.

I would argue that your statement above is akin to the 100 MPG car company citing a drop in the price of gas as an excuse as to why my 100 MPG car, that only gets 30MPG is "fine".  
Dude, you were the one who brought money-making into the debate in the first place:

Everyone here understands that delivering at a 14,000GH/s Network rate compared to at 120,000GH/s is VERY different.  When you have been emphatically told you are receiving it at the 14,000 point and you get it when the device will produce 1/9th of what you assumed, you have been scammed.
And I don't know why you brought that up, only to later say this:

BFL has no control over that
If you're going to argue about something, at least be consistent about where you stand.
999  Bitcoin / Hardware / Re: BFL's Jalapeno exists - I have one in my hand and just uploaded a video on: April 25, 2013, 06:46:54 PM

I get the animosity towards bfl because of josh and the delays, but from what i see they are an actual business  with facilities employees etc. They shipped fpga product and asics now. Really , do you seriously still think its a scheme, vs poor project and perception mangement?

I would think COGS on a Jallie would be around $80.  Then there are operating costs (think rent, wages of 22, electric, ads, phone etc) to cover with the gross profit of $67, which they could not cover at this production rate.
So, to answer your other question, it really depends on what you mean by scam/scheme.   Using pre-order money to conduct research and development of a product you have no experience nor idea how to produce is a scam.   It was not presented that way.   It was not presented as "give me your money to TRY and make an asic but btw, I have never done this before and I am assuming you can google a clue (or buy one with a quarter so to speak)".
It was presented as "we will ship an amazing product in three months and everyone else is an idiot (implying BFL were the EXPERTS at making ASICS).   That is a scam.

To your point of "they are now delivering".   Everyone here understands that delivering at a 14,000GH/s Network rate compared to at 120,000GH/s is VERY different.  When you have been emphatically told you are receiving it at the 14,000 point and you get it when the device will produce 1/9th of what you assumed, you have been scammed.

Sort of like pre-ordering a betamax and getting it in 1988.
It's not a scam if you get your money back.  BFL has always honored refund requests.

BFL also made no guarantees regarding the network difficulty.

It is also worth noting that, between June 23rd and today, the price of BTC has gone up 27x while the difficulty has gone up 9x.  So, it is actually 3 times as profitable to mine today as it was back on June 23rd, 2012.  If anything, isn't that the opposite of scam?  The money-making product you bought will actually make 3 times MORE money as was projected when you first ordered it?
