The coins aren't in limbo. Such a transaction would not be accepted by the network so your 12 BTC is still usable in another valid transaction.
Yes, but the client instantly deducts the 20 as soon as it says "payment sent"... long before the network has a chance to see that it's invalid. So the client says 0.00 even though only 8 out of 20 was a double spend. Maybe I do have a corrupt wallet.dat (or several). I'm not ruling that out. |

Well, the above scenario appears to have happened to me.
I'll try to gather real-life details shortly... m0Ray was helping out with it in another thread.

Please imagine the following scenario:
I have a new wallet on device A which I receive 2 transactions:
12 BTC
8 BTC
So my balance is 20 BTC.
I then copy that wallet.dat to an installation on device B.
From device B, I spend exactly 8 BTC, leaving a balance of 12 BTC
(I assume this spend should come directly from the address that received 8 BTC so 'change' will not be an issue).
Let's say this 8 BTC spend gets old and has many confirmations.
Now, I go back to device A, which still shows a total balance of 20 BTC.
I then 'spend' the whole 20 BTC, dropping the balance to 0.00 in the client display.
This transaction should never be confirmed as 8 of it is a double spend, so my question is:
How to get the 12 legitimate coins back from this state of limbo and back into my balance?

Loads almost instantly for me. Chrome 11.0.696.68, Ubuntu 11.04. Scroll wheels work. Really cool project.
Okay, don't know then... I left the page open for 15 minutes and it's a really nice looking page, but no globe  Chrome 11.0.696.68, Windows Version 5.1 (Build 2600.xpsp_sp3_gdr.101209-1647 : Service Pack 3) Edit: Nevermind, I forgot I didn't have Direct X installed since I re-installed Windows recently... downloading it now |

Okay, installed a fresh copy of 0.3.21, replaced wallet.dat with my old one and let it download the block chain to 125784. And that transaction is finally showing as confirmed. Now a separate issue... Could someone make sense of this one for me? (Sorry, copying text from Transaction Details window still doesn't work in this version either).  This has also been unconfirmed for a long time, and it's not in a block yet (cite blockexplorer.com), but also not listed as unconfirmed on http://bitcoincharts.com/bitcoin/That site normally lists any unconfirmed transactions that I search for, but not this one. I'm wondering if somehow a double-spend has occurred and this will be unconfirmed forever. (This wallet balance is 0.00). ...But how can you tell for sure if that is the case, or if I just need to wait longer for it to show up somewhere? Thanks very much. |

Doesn't work for me in Chrome 11. (Globe doesn't show up at all).
Shows for me on Chrome 11.0.696.68 Also, the scroll wheel does zoom in Chrome... doesn't seem to work in Firefox 4, though it could be due to an addon. That's exactly the version of Chrome I have. Most of the page loads, just not the globe... how long should it take? |

To view, you need a WebGL compatible browser. That is Firefox 4 or Chrome 9+ I think. Doesn't work for me in Chrome 11. (Globe doesn't show up at all). |

If you already redownloaded after the problem developed, then doing it again probably won't help. You can't have gotten a bad copy, since Bitcoin checks the blocks before adding them to the database (unless you manually replaced the files).
Okay uh, I just deleted the block chain before I read your post  Anyway, I was on 3.20 so I'm getting 3.21 now and obviously I'll be getting the block chain again. |

You also need to delete blk0001.dat and blkindex.dat. I think this is a rescan bug.
Damn, really? I just re-downloaded it 2 days ago. Perhaps it's the node that I'm adding that has a bad copy of it? Could someone else give me a node to connect to so that I can be sure I'm not getting it from the aforementioned x.x.x.x? Thanks. p.s. Thanks for the code m0Ray, it'll be an interesting read, however I haven't compiled C since uni quite a few years ago now. |

 All of these (inputs+outputs) are in blocks as shown by blockexplorer.com. |

I've got this problem too... deleted everything in the data dir except for: wallet.dat blk0001.dat blkindex.dat restarted bitcoin with: bitcoin -addnode=x.x.x.x -rescan -debug and it still tells me the following is 0/unconfirmed: (Uuuh, actually, copy+paste has never worked for me in the Transaction Details window on Windows XP client). I've tried Ctrl-C, Ctrl+Ins, drag-n-drop, right-clicking the text with the mouse... nothing will copy it to the clipboard.

I once had this too. If your payment gets confirmations, it'll be received. Contact the person you was sending the payment to.
Thanks, it's weird, they got it and obviously their server got a data post, but mybitcoin still only shows the 'payment timed out' page. I guess it's no problem, just mybitcoin's error page could be more helpful. |

Hi,
I was making a payment via mybitcoin.com, and I did actually make the payment (I can see it in my client as 0/unconfirmed) however somehow the broadcast didn't reach mybitcoin quick enough and it says:
PAYMENT TIMED OUT! We didn't receive a payment from you. Try again.
I tried refreshing the page but it just says the same thing, so my question is, how can I try again without spending double?!
Thanks

I've been trying to find documentation on what the sendfrom function actually returns... True or false or something more detailed? try {
$bitcoin->sendfrom($acc,$addr,(float)$amt);
} catch (Exception $e) {
die($e);
}
Edit: Okay just did a test and it appears to return a txid... is this documented anywhere handy yet? Had no luck searching for it in Google. |

I'd suggest removing/replacing the "it is anonymous" claim.
And the 'no one can track your purchases' claim, actually. |

Again, you pick a website for which you don't have to guess.... Again, a famous newspaper will do.
My point was only that there is no website so famous that foreigners will be able to read it and validate it (and 'not have to guess'), however a QR code can be embedded in a site of any language. |

Is BBBB.com taken?
As far as I'm aware, every 4-letter combination is... all 456,976 of them. |

I don't really see how that's more convenient than photographing your baseball card with the nytimes.com in background.
Oh wait a minute, the nytimes.com solution doesn't require you to scan any sort of fancy QR code.
My point is that your idea doesn't really solve any problem in a much more elegant way than the outlined solution.
The OP mentioned that it would take a lot of time to authenticate if the newspaper were Chinese... on the flip side, a photo of the NY Times may take a long time for a Chinese/Other person to authenticate. This is why I specifically mentioned a newspaper website, not a physical newspaper. If you can scan a QR code and verify a signature with a smartphone, chances are that you can access any newspaper website. If you went to a Chinese website and it looked exactly like in the photo, how would that help you to know how recent it is? You could guess that the website is updated every day, but what if it isn't? If the page is completely stale (and only contains foreign language), you'd have no way of knowing how old the photo is. |
