china will go thru 5500 soon, they already punctured it and now they are oversold
Having seen my magic, perhaps you can now publicly acknowledge that I have 10,000 bitcoins, apologize, stfu and gtfo. OK?
If you want to prove that just sign a message with an address holding 10k and put that signed message in your signature - no need for nobody to "acknowledge", that would be a hard cold proof.
That's pure non spoofable crypto, heart and soul of Bitcoin.
That's not hard cold proof. It's susceptible to Man in the Middle attack.
Care to elaborate that? How could rpietila perform "a man in the middle attack" and make bitcointalk.org users to believe he signed a message with an address holding 10k BTC if he is not in control of an address with such an amount?
Because there is nothing linking the Bitcoin address to his forum account. Hypothetically speaking, he could just ask a friend who has access to 10K BTC to sign a message and just post it. The difference is there is the possibility he can get 10K BTC account to sign a message, but he may not necessary control it.
But that's no man in the middle attack, in that case Risto would just be "borrowing" the coins for a specific purpose - signing the message, which is a proof he can have access (at least for that very purpose of signing the message) to 10k coins.
In any case, only a retard would accept to use 10k of his own coins to sign a message like "this coins belong to Risto Pietila", in practical terms Risto's "friend" would be handing to Risto the control of those bitcoins. That's like signing a contract, explain to a judge that "it was just a favor".
No.
The owner of those coins could sign the message
for him. Risto would never need to control them. Virtualfaqs is right.
Finally:
If I have to prove on a forum that I own a $10M mansion, how about uploading a valid and verifiable contract of ownership of such mansion in my name? Wouldn't you consider that a proof of ownership?
Justin Bieber could be my friend and he could have signed a contract transferring to me the ownership of his mansion as a favour, but without ever handing to me the keys. I might never have intention to ask him for the keys nor to live in his mansion, I could just want to show off in here... But JB agreeing to underwrite such a contract is beyond retarded and plainly ridiculous. As retarded, ridiculous and unlikely as expecting someone to cryptographically sign a message such as
"This 10k BTC belong to Risto Pietila" with an address holding 10k BTC that do NOT belong to Risto.
Probably you do not fully understand the strong implications of such a message - any cryptographically signed message is potentially binding, and that's why the QT client warns you about signing only messages to which content you fully agree. If Risto has such "friends" that sign those messages for him I congratulate and envy him.
