So, imagine a case where someone was trying to prove that the defendant owned a given bitcoin address corresponding to a brain wallet. The only way to prove ownership is the show that you can produce the private key. If the same principles/rights that apply in the case above applied to a case like that, they wouldn't have to produce the key. Am I missing something or is that absolutely awesome for bitcoin?
If the defendant has used his private key to sign some agreement, it can be used to prove the ownership of that public address as well. Or am i wrong?
