Current version is based on v2.2,

Current version hosted on BitAddress is v2.4.

If GitHub has a version tagged for v2.5 that might mean release is imminent.  Does v2.5 have encrypted wallets?

You need to do it with raw transactions.  If you use the satoshi client then you can use it; or you can use if you want.

That may not even be necessary.

If the original transaction didn't get relayed very well because it was below 0.01 BTC and no fee then a node running Bitcoin-Qt wouldn't know about the original transaction and thus wouldn't have a problem creating a spend transaction.  So simply importing one of the private keys used in that transaction to Bitcoin-Qt and spending it (with a fee) might be all that is needed.

But seeing your suggestion to use ... that is probably an even better idea than trying to get a Bitcoin-Qt set up just for this one transaction.
1263  Bitcoin / Bitcoin Technical Support / Re: Addresses are missing, cannot create new address in Bitcoin wallet on: April 12, 2013, 06:33:01 AM
I'm not sure what's going on, but when I go to my bitcoin wallet's address book, my addresses are missing, and I cannot create a new one either. When I try to create a new one, it's prompting me for an address as well as a name for the address. Previously, the address field was grayed out and it would generate that on its own. My balance and transactions are valid, so it's not as if the whole program is not working, just the address book. Probably completely missing something here. Any ideas?

I can't even tell for sure what client you are on from your description.  Are you talking Bitcoin-Qt client?  Or some other client?

This arrangement is ideal for people who like to bend the rules without breaking the law

Does that mean something like buying two one-way trips with a layover in the desired destination but then not continuing on the last leg of each trip?

I don't have any immediate travel needs so I won't waste your time with a request, but if you have any recent trips like to a commonly requested destination where you've already done the research and could share that here I think it would be interesting.  I'ld like to see how that compares to what I'ld find if I were to try to do that search myself.
1265  Bitcoin / Bitcoin Discussion / Re: What are you guys down about? The future of Bitcoin never looked so bright! on: April 12, 2013, 02:25:53 AM
You can think what you want, but this is IMO the point of no return. 

I'll agree there.  Still having roughly a $1 billion total dollar valuation (TDV) after "the crash" says something. 

Even with many merchants essentially having been frozen, unable to determine price, the number of transactions occurring for the day barely dipped. 

And BitPay never stopped processing transactions, just that the exchange rate varied wildly minute to minute:

And every day there are more merchants coming onboard.

I just read about BitFetch, which pulls torrent files for you so you can download them without a torrent client (after paying BitFetch to grab the file for you).  Services like that would not exist without Bitcoin.  Those businesses alone are enough to justify a $1 billion total dollar valuation (TDV) for all bitcoins.
1266  Bitcoin / Bitcoin Technical Support / Re: Tech help needed with Instawallet claim process on: April 12, 2013, 01:22:12 AM
The wallet that sent funds to the Instawallet is a Blockchain wallet.

I have no clue how to do this. Can anyone please advise?

Sign in to

 - Receive Money tab
Locate address for transaction that funded one of your deposits to Instawallet

Click on Actions pull-down tab.

Click Sign message.

For the message, you can do anything you want  (e.g., "The Instawallet at is mine." )
and then on the claim form give
1.) Your bitcoin address used to sign the message (and used to fund the Instawallet)
2.) that message (e.g., in quotes above)
3.) the signed message

What is happening here? They're closed... Is this just fulfilling the last orders?

For a total of like 2 BTC.  Someone in #mtgox on IRC was wondering why when a Dwolla transfer finally got credited that those funds were used to buy 2 BTC immediately.

So these two might be related.

For those not familiar with CBC, it's Canada's public broadcasting corporation with nationwide coverage.

"The Current" is the primetime country-wide morning radio show on CBC-1.

Yup, ... the media is pulling out all the stops.

As Big Investors Emerge, Bitcoin Gets Ready for its Close-Up

Cameron and Tyler Winklevoss have been many things in a short time: Olympic rowers. Nemeses of Mark Zuckerberg. Characters on “The Simpsons.” Now they can add a new label: bitcoin moguls.
The Winklevii — as they are popularly known — say they own nearly 1 percent of that, or some $11 million.
Now mainstream investments in the digital money are starting to emerge. On Thursday, a group of venture capitalists, including Andreessen Horowitz, announced that they were funding a bitcoin-related company, OpenCoin.
But the 6-foot-5 Winklevii were unfazed by the latest tumult. Indeed, the brothers said they used the low prices to buy more. They argue that bitcoin will have much further to soar once a broader audience sees its virtues: a unit of exchange that can be moved around the world at the click of a button without requiring any payments to Western Union or American Express.

“People say it’s a Ponzi scheme, it’s a bubble,” said Cameron Winklevoss. “People really don’t want to take it seriously. At some point that narrative will shift to ‘virtual currencies are here to stay.’ We’re in the early days.”
For their part, the Winklevoss twins have used some of their bitcoin to pay for the services of a Ukrainian computer programmer who has worked on the site of their venture capital firm.
In addition to the purchase of bitcoins, they also say they have invested in a bitcoin-related company, but declined to disclose which one.
“It has been four years and it has yet to be discredited as a viable alternative to fiat currency,” said Tyler Winklevoss. “We could be totally wrong, but we are curious to see this play out a lot more.”

1272  Bitcoin / Bitcoin Discussion / Re: How do I attempt a double spend? on: April 10, 2013, 10:21:09 PM
... umm for science  Wink

But in all seriousness, I attempted to send some trivial amount (.1 mBTC) without a fee from the Android wallet app and the transaction has been hanging in limbo for the better part of a week, leaving a few bitcents that I can't use. My understanding is that the only way to use those coins is to a) wait an indeterminate amount of time until that transaction gets accepted or b) double spend that "chunk" to myself with a fee to get it into the block chain in short order.

From the Bitcoin Android wallet app?  or from for Android?   or something else?

That's a long time for a transaction to hang out there without getting a confirmation.  The original sender must be re-broadcasting it periodically (which is what the client is supposed to do).  

But because it has an output below 0.01 BTC and it has no fee, not all nodes are relaying it.  So you still might be able to spew out a double spend that would get relayed.

So if you have the private key for the address from one of the inputs for that send transaction you can import that address into the Bitcoin-Qt client, or Multibit, or Electrum, etc. and try to spend from one of those.  You'll have the same problem if the amount is below 0.01 BTC  and you don't pay a fee though so make sure to pay the freight.

[Update: Just remember though, with Bitcoin-Qt if that is a failed double spend attempt there's no way to delete the offending transaction from the wallet (without using the third party tool, pywallet, to perform wallet surgery).  So don't do this with your normal wallet.dat for Bitcoin-Qt, or at least make a backup right before so you can restore the old one if the double spend attempt never confirms.]

Can you give me some names of the bitcoin wallet services that got hacked in 2011

Maybe in this list?

List of Major Bitcoin Heists, Thefts, Hacks, Scams, and Losses

There was really only one "E-Wallet" that saw losses, MyBitcoin.  There were a couple of exchanges in which accountholders had losses, like Bitcoin7, and some services ... like Mooncoin, but E-Wallet services MyBitcoin was the biggie.   And that's long long gone.
1274  Economy / Trading Discussion / Re: Mt.Gox to US bank - avr time on: April 10, 2013, 04:08:29 PM
Follow up to question below.

Your question will vary based on a few factors including how much you are transferring, is your account verified, what day of the week is it, what hour of the day is it, the size of the payout queue, the size of the support queue if there is a problem, the color of "the developer"'s socks, and more.

If you are asking for International wire, that will always be at best about a half day because of the difference in time zones.

For the transfer from Mt. Gox to Dwolla, that can range from very quick (hour to several hours range).     Once they do the send though the Dwolla transaction (an account-to-account A2A transaction) is instant.   

Then your withdrawal from Dwolla is about two business days, assuming you've already linked a bank account to your Dwolla account.  They may do a hold if they decide to require your identity (upload a photo of your driver's license).
1275  Bitcoin / Press / Re: 2013-04-09 What Bitcoin Is Teaching Us on: April 10, 2013, 10:43:14 AM
Here's the money shot:

Here’s what beautiful about this experience: It doesn’t matter in the slightest what Paul Krugman thinks. It doesn’t matter how many economic experts Paul Krugman lines up to oppose Bitcoin. It doesn’t matter how many Nobel Prize winners denounce it and oppose it. That’s because Bitcoin is not a “policy” invented by elite and privileged intellectuals. It is a market-based currency, one created by an entrepreneur and chosen by market players.
[emphasis mine]

And that is exactly the message that needs to be shared.

If bitcoin continues on its current trajectory being wildly successful (specifically its recognition and use as a currency) and that success will bring huge shifts and dislocations, then there will be a huge shifts and dislocations.  (And hopefully they come to the bloated financial sector first  Grin )  But it is like the entertainment industry saying how they don't like MP3 sharing.  Well, they can stomp their feet and make a bunch of theatrics but in the end MP3s will be shared.  Bitcoin, like the internet, routes around "damage".

The genie is out of the bottle.

1278  Bitcoin / Development & Technical Discussion / Re: Make transactions in blockchain untracable on: April 09, 2013, 12:13:06 AM
If we trust cryptography we dont need to see the transactions to accept that double spending has not occured - correct?


This is the data that is needed.

A transaction is a signed section of data that is broadcast to the network and collected into blocks. It typically references previous transaction(s) and dedicates a certain number of bitcoins from it to one or more new public key(s) (Bitcoin address).

1279  Bitcoin / Development & Technical Discussion / Re: Make transactions in blockchain untracable on: April 08, 2013, 11:25:02 PM
Is it technically possible to encrypt the blockchain so the transactions becomes totally impossible to trace for others than the two parts involved in the transaction?

The reason: make it impossible for government to trace how much bitcoins you have, who you have transactions with and so on.

The architecture of the Bitcoin ledger is such that each node can verify that a transaction has not been previously spent.  There's no way to verify that the transaction hasn't previously been spent without knowing the address and the transaction details (transaction hash and index).

There is a somewhat related project, Open Transactions, that allows Bitcoin transactions with blinding.

Does anyone know anything about this service?

It is hosted at the same IP address as  They also are registered with privacy protection.  And it was another service that, if successful, would receive payment and then hold large amounts of funds until eventual payout.   Which is an interesting coincidence.
