This is a neat, little game. Maybe I'll try it sometime.  |

OP was online recently, but doesn't seem to be responding to thread or PM's so far.  |

How much would you offer if I added it to my website?
I will PM right now.

Well, it seems that this situation is going to be resolved soon. They will certainly secure their site from this flaw and avoid a repeat of this incident again in the future.  |

However, since I use a strong password + 2-factor login authentication at blockchain in addition to having 2-factor login authentication on my e-mail account, I think that I shouldn't have anything to worry about.

Every time you send a bitcoin transaction from your blockchain.info wallet, the blockchain.info software needs to use a private key to sign that transaction. If they re-use an R value that they used on a previous transaction, and you are re-using the same bitcoin address in your blockchain.info wallet for multiple transactions, then attackers that monitor the bitcoin network will be able to compute the private key. They won't need your "strong" password, and they won't need your 2-factor login. The hacker can simply create and broadcast a transaction that empties your wallet. Should such an event take place, shouldn't Blockchain.info be held liable? After all, it's their system that would have caused the screw-up! |

It's back up but it looks strange now!   |

Thanks for the explanation Danny! Well I can tell you that I am certainly not interested in that level of technical detail.  However, since I use a strong password + 2-factor login authentication at blockchain in addition to having 2-factor login authentication on my e-mail account, I think that I shouldn't have anything to worry about. I recently had a blockchain issue where my ip address was changed from my modem and I had ip security authentication enabled and got blocked from my account. I contacted support with my details and they reinstated my account 2 weeks later.  |

Mr. Burns...Are you attempting to burn Bitcoin?  Why such a snide remark |
|
|
|
|
I would be very grateful if someone could explain what is this R-Value problem I am reading about.

So what's up with Hashie |

Your work is very professional but your maximum prices are simply too high in my opinion. If I want something, I'll consider buying from you. |
|
|
|
I am very interested in this campaign, I will submit soon. |

If you have any Full Member accounts for only 0.1BTC, I would be happy to oblige. |
|

Wow!!! This was a very interesting read. |
|
|
|
Sounds like a complete waste of money to me but that's just my opinion. After all, one man's trash is another man's treasure!  |
|
|
|
I would take it for 0.1 BTC...but your minimum is a little too rich for my blood. |
|
|
|
Price seems a bit high in my opinion!  |
|
|
|
Well this thread is quite enlightening. Thanks for the info on the value of such accounts.  |
|
|
|
Why would anyone want to buy that account? It's basically worthless! You must be joking! |
|
|
|
I really like lotteries, so I'm going to give it a try! |
