As far as i know the "master key" is only for messages. Anyway, the client is opensource so it's not like they can hide a code that will let someone control everyone  |

Those who have large investments in bitccoin can revive it on their own to maintain their investment. The rest of the users profit as well from the open source design. |

There is no master key. That would make it all worthless.
The "master key" in this case is the key that is used to sign messages that get broadcast to all nodes, for instance to warn of a security vulnerability. As far as I know, that particular key isn't used for anything else, but I'm not sure of that. There is no such of that kind of master key, either. That was only a proposal discussed a couple years ago that never went anywhere. It's been used several times. If you install an old client, you will see a warning at the bottom that says that it is insecure and needs to be updated. That warning message is actually stored in the blockchain. |

so if gavin gave the CIA that key. then the cia could corrupt the blockchain whenever they want? or at least make a malicious bitcoin client "update"

The functionality is just for messaging, it can't force an update or anything like that. Worst that I think could happen is they send a message that shows at the bottom of the client window that says the client needs to be upgraded because of a security problem. But then, they would also have to create a bogus update, get it signed with a DIFFERENT key that is used for software releases, and upload it to github/sourceforge without being detected. It would be difficult and complicated to pull off. |

No. The only thing that this key can do is signing an alert message that propagates through the network. Satoshi, Gavin and theymos have this key, IIRC. |

It's been used several times. If you install an old client, you will see a warning at the bottom that says that it is insecure and needs to be updated. That warning message is actually stored in the blockchain. No, it's not. It's an alert message that is being broadcast into the network. Each client can decide if/how show it. Also, in principle, different clients could use different signing keys. |

So what you are saying is that such messages are being shuffled around in limbo via the P2P network, but don't touch the blockchain ever? |

No. And what "method" are we talking about, because I know of no such method. |

Yes - if Gavin has been consorting with Harry Potter recently (I see no evidence he hasn't). |

The cia is more likely to use bitcoin than destroy it. There is nothing better to pay spies with overseas  |

I wouldn't be even a little surprised if it turned out Satoshi and Bitcoin are creations of the CIA
Doesn't matter really. The day they open-sourced it, they lost control over it. Now everybody can benefit from Bitcoin, and nobody can control it without using **significant** money and resources. And I mean multi-billion-dollar-significant (however even that money doesn't guarantee success). The Internet is also a creation of the military. Who cares ? |
