Could bisq’s use of Tor provide any risk exposure to bisq users?
Good question. Haven’t read this in detail yet. however, i don’t believe Bisq ever sends anything over clearnet so it shouldn’t be an issue… although I may be wrong here. If a user is using a bitcoin node that isn’t going through tor then perhaps.
From what i remember reading exit nodes are being used to switch out peoples bitcoin addresses with malicious ones. As long as the communication remains within Tor you’re fine.
