The Monero Research Lab (MRL)

The Monero Research Lab (MRL) has decided to recommend that all Monero node operators enable a ban list of suspected spy node IP addresses. The spy nodes can reduce the privacy of Monero users.

UPDATE 14 January 2026:

MRL ban list version 2 released. It is available at the same URL as before: raw.githubusercontent.com/Boog900/monero-ban…ban_list.txt. It is recommended to update to the latest ban list. The vast majority of spy nodes in the old ban list have switched to different IP addresses.
