Electronic information cannot self-destruct. It can also be easily be duplicated. If the tx has been broadcast with an appropriate fee, and subsequently heard, it is inevitable it will reach the blockchain. The Bitcoin client is quite aggressive at re-broadcasting to other peers. The cat is out of the bag.
If the recipient is well-connected to the network, they might with some degree of confidence accept a 0-confirmed tx if they have heard no double-spends.
If 'thin' clients started to heavily rely a few exit nodes, and peer numbers dwindled, it might be possible to conspire with large pools to somehow repeal a tx before it was broadcast. However, we'd have bigger problems if this were the case.
Irrevocable transactions is alien to to some people. As is the concept of complete and total responsibility for the storage of one's own store of value (wallet). This is probably the price of a distributed crypto-currency. There is no one to point the finger at.
Just the answer i was looking for. Essentially a 51% is needed for both double sending and repealing in the same. All is good, the world makes sense once again. |

So i do understand the basic principle of seeing that a transaction has been confirmed in the blockchain, however there is definitely a stigma against unconfirmed transactions. My question is, is it even possible for someone to 'take back' an unconfirmed transaction? At the point that it has left your wallet, is it not technically in the recieving wallet until confirmed (just floating around waiting for a confirmation)?
An example is that a transaction to satoshidice can be sent and reward recieved without any confirmations, thats a mindfuck to me.

Ive decided to start selling a few domain names which have 1 year registration to those who want it as i know it can be a pain for some people to pay $10-$15 for a years registration and this gives you an opportunity to pay in BTCitcoins! .5 BTC Domain Name Suffixes:- .com
- .org
- .net
- .biz
- .info
- .name
Please make sure that the domain is available before requesting. If you are at all interested, send me a pm or post here and i will get right on it! Note: These may need up to 24 hours to be fully registered. |

i'd like to send my brother thousands of dollars at a time..so if theres a 12% fee that would kill my pockets..
hmm..
You should use the Bitcoin-OTC then. Maybe it's the best way. Or follow the advice John gave you and get in touch with Tangible Cryptography. The less middleman, the better for you. yeah OTC sellers dont have very high fees in general. sometimes even 1:1 |

thanks guys this is all so confusing.
Me buying bitcoins using my bank account leaves a papertrail no? I have to deposit money into my bank account, then buy bitcoins.
Also, can I cash out the prepaid gift card?
It would show you depositing into the exchange, yes. From there on out, theres very very little to be done about seeing where that went. You can do more than just convert them to a prepaid card though. paypal(recently accepted), deposits to bank accounts, etc. |

The great thing about bitcoins is the anonymity! you deposit USD into an exchange, buy bitcoins, she will have no way of figuring out who's recently bought coins are yours. send them to him, he cashes out, no paper trail. You should also look into https://www.spendbitcoins.com/convert/ for cashout options for him if he doesnt specifically need cold hard cash, or hell, even if he does theres options for that. |

Bitcoin turned my $200 investment into $30000 (during the bubble) into $7000 (now).
I'm a software engineer, and I'm about to start a really awesome job after 10 years at a different company. However, a bitcoin-related job is my dream. They just don't exist yet (at least, not for a guy with 3 kids and a mortgage).
Lightbulb! thank you much  |

Is it wrong that the below image is what came to my mind first when I saw Bitcoin and Trip in the same word/sentence?
No, and that picture just made my archives  |

|
Yes.
I agree with sir troll |

I thought it was about spending bitcoins while tripping on acid.
Me too  Huzzah! I'm not insane! This does not mean you are sane. He could also be insane. Just sayin. Ahh so true. But yet, aren't we all insane? Sanity is a measure of societal acceptance and as we mentally ill see it, society, for the most part, is a paradoxical insanity! |
