Questions people ask
What is a Monero spy node?
A node run to watch the network instead of serving it. By operating many nodes, an observer can try to link transactions to the IP address that first broadcast them. Spy nodes cannot see amounts or addresses, and they cannot take funds.
What is the MRL ban list?
A list of IP addresses and ranges that Monero Research Lab contributors identified as likely spy nodes. Node operators can load it so their node refuses to connect to those addresses. It is opt-in and signed by several Monero developers.
How do I use the ban list on my own node?
Download
ban_list.txt and start monerod with --ban-list /path/to/ban_list.txt, or add enable-dns-blocklist=1 to use the DNS-based list. See our guide to running your own node.An IP is not on the list. Is the node safe?
Not necessarily. The list only covers addresses that were identified, and operators can move. A remote node always sees your IP address and when you send. Use your own node, or connect through Tor, if that matters to you.
Do you log the IP I check?
No. The list is loaded with this page and the comparison runs in your browser, so the address you type is not sent to us.
