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?
A signed message is proof you control a certain bitcoin address, a new address wont do. You are usually asked to sign a message with a specific address that you controlled in the past.
