Re: Signed message... breaking?

So i am writing with signed message question again, this time i couldn't find info.

So signed messages proves something, for example, that we are owner of wallet or account or something else(most common uses that i found on this forum), and everyone trusts it.

But what if person that signs it, lies about it? It shouldn't be hard to use tor, new wallet, and that's all. So why signed messages are so trusted?

If you are confused with like, someone can lie about themselves and scam anyone, then you didn't get the concept completely.
I think people are allowed to provide their bitcoin address on their profile as well they have a thread where they can stake their address and as long as it gets older and you gain trust, then only you will be proven trustworthy, else using new wallet and signing a message for anything couldn't get your work done if your intention is to scam. That's why you need to stay alert, and if you are unsure about such problems, you can let a third party to come between that person and you for anything, like your trade to become more secure.

That's for your large answer. Also, how can i know how old any wallet(or address?) Is?

The point is that you posted an address to receive payment in the past, or you have staked the address on the forum. So that essentially proves that you owned the address whilst you are still being trustworthy and dealing with bitcoins.

Say, if you take a 1 year holiday from the forum and come back, people suspect you to be hacked.

If you can sign a message that is able to reflect that you still own the old address, that's how you prove that you're not a hacked account.
