Bitcoin Core 31.0 Privacy Bug Exposes Sender IP Address
- Privacy Vulnerability: Bitcoin Core 31.0's private broadcast feature has a bug that can expose the sender's IP address under specific network conditions, affecting users who rely on this feature for privacy, particularly those sensitive to privacy risks, potentially allowing their transactions to be monitored.
- Mechanism of the Bug: The issue arises when private broadcast connects to an IPv4 or IPv6 peer that supports BIP324 v2 transport; if the v2 handshake fails, the system falls back to a direct connection, revealing the sender's clearnet IP address and undermining user privacy protections.
- Recommended Workarounds: Until Bitcoin Core 31.1 is released, affected users can mitigate the risk by disabling the feature with -privatebroadcast=0 or routing all outbound traffic through Tor, ensuring their IP address remains concealed and protecting their transaction privacy.
- Importance of Network Privacy: This bug highlights the risks to Bitcoin privacy at the network layer, as the exposure of a clearnet IP can be combined with timing and geolocation data, threatening user anonymity and emphasizing the need for users to be vigilant about their privacy measures.
