Incidentally, there are now similar gadgets used for offline hardware wallets:

Piper - A hardware-based paper wallet printer and so much more

New Version of my Offline Paper Wallet Generator

And continued interest in this topic:

Raspberry Pi as an offline wallet?

Rickards describes "a lot of problems with it, we'll get to it in the main program".

So they had more discussion specifically on Bitcoin, or was Bitcoin just something he'ld bring up later during the event?

I want to remove a private key I added a while back that has a lot of spammy transactions (think 'correct horse battery staple', except it's not the one) from my wallet.

How do I do this? Obviously without creating a new wallet and transferring everything there, please don't offer that as an option.

According to the following instructions for a specific pywallet, delete an address is possible:

I guess it only makes fiscal sense to mine on an industrial scale. Who would be interested in colocating bitcoin miner arrays in a datacenter?  Grin

No, that's not correct.

GPU mining is done for, permanently.  It doesn't matter how much you are scaling, it is now unprofitable (or rapidly nearing that point) to mine on GPUs.

But even the small ASIC device (e.g., Jalapeno) is competitive against larger operations ... meaning the cost per Ghash/s for hardware is not that much different whether you are buying a 5.5 Ghash/s Jalapeno or some 1 Thash/s monster, and they are not dramatically different on power consumption (when compared to the value of the bitcoins that are the result).

Now, along with minor visual improvements, this page is going to require a one time password to be entered for any withdrawal operation, if you have tied Google Authenticator to your account.

I notice that simply doing a password reset through e-mail can successfully bypass two-factor authentication (2FA) protection as I can withdraw funds without 2FA after resetting the password.

Shouldn't the 2FA code be required to request a password reset (when 2FA is enabled)?

I wish we could somehow have a second version of bitcoin which held a stabilized value. Today for example it dropped almost 10% in a matter of minutes...that kind swing just makes it hard for joe blow retailer to start accepting it.

Jav is on it!

Indeed, all proof of work based scamcoins are doomed unless they can overtake Bitcoin.

I wouldn't go that far.   Protection simply needs to be at a sufficient level to where performing an attack is both economically costly and unprofitable.  Litecoin might reach that, but I don't know that today it is sufficiently protected.

Mr. Bitcoin goes to Washington
by Jerry Brito

On my panel were representatives from the Bitcoin Foundation, the Tor Project, and the DOJ, and we had a lively discussion about how these technologies can potentially be used by criminals and what these open source communities might be able to do to mitigate that risk.
I was therefore interested in the keynote remarks delivered by Jennifer Shasky Calvery, the Director of the Treasury Department’s Financial Crimes Enforcement Network.  [In particular, she addressed the fact that since there have been several enforcement actions against virtual currency exchangers and providers, the traditional banking sector has been wary of doing business with companies in the virtual currency space.
It would be a shame if [banks] felt they couldn’t do business with an innovative new kind of start-up simply because that start-up has not been (and may never be) adequately defined by a regulator.
Hopefully FinCEN will revisit its guidance now that the conversation has begun, and as other regulators consider new rules, they will hopefully engage the Bitcoin community early in order to avoid ambiguity and uncertainty.

This was originally from Business Insider:

Incidentally, I find it irresponsible at best to write about Litecoin to a general audience without discussing proof-of-work, the risk of 51% attack and the difference between Bitcoin and Litecoin in this regard.

This is a cool idea! Makes me want to form one in Southern California.

What a coincidence!

It was a fantastic event!   There was about 30 people at one point and total attended could have been even higher if some had left early or arrived later.

There wasn't a huge amount of trading ...  but the buyers were paying over spot. 

And there was a special guest appearance too!

Sources please?

The stock market traded at two-month lows after Greece became the first developed nation ever to be lowered to emerging market status by equity index provider MSCI.

The national Greek TV is going dark, though the journalists are offering to work for free using social media (including Youtube).  

Though none of that means Bitcoin will rise, it just means troubles around the world (yes, including Cyprus, Argentina -- like no more sending Western Union out, France -- like no currency sent through the mail, Thailand, India, and more) are not "fixed".  And Bitcoin is one of the options that remain for those looking to diversify their holdings or to transfer their money.

How digital currencies democratize tax evasion
by Tim Fernholz

The two tools Liberty Reserve used to evade financial scrutiny—anonymity and layering transactions through multiple companies—are already embedded in the international financial system. The difference now is merely access and scale.
When offshore financial centers first became trendy many, many years ago, you used to have to go to the offshore location, take the money with you, and deposit it in the bank. Now [open up an offshore bank account] you don’t have to go to Guernsey or Cayman or BVI.
The internet has shrunk the world, and Liberty Reserve and other digital currencies similarly help bring offshore banking to the masses.

Rather than have the math problem computers crunch to verify a block during the mining process--would it be possible to at the same time make the math problem one that would contribute to research efforts?

The reason the Bitcoin network requires a large amount of computing power is to enable decentralization, with a proof-of-work being the tool employed.

But that computing power is for a specific purpose, ... to make it so that the decentralization is immune to corruption.   That's the only reason there is this large amount of computing power.

But the proof-of-work computation that is performed is useless for anything else.  

Now that doesn't mean there computing resources that Bitcoiners will (soon) abandon can't still have use for scientific purposes.

CoinLab was making inroads to doing this but got stuck on how distributed scientific computing is a hard problem to solve with little opportunity to monetize it.

So essentially, the Bitcoin project has paid the way for there to be many tens of thousands of (soon-to-become) unused GPUs that have potential value for doing scientific computing work.
