Monero releases ‘Flourine Fermi’ update to fight spy nodes

Monero’s “Fluorine Fermi” update enhances privacy by fighting nodes that try to link user IP addresses to their transactions.

Privacy blockchain Monero has rolled out a new client update to provide users with greater security against “spy nodes” on the network.

The “Fluorine Fermi” software update was announced via X on Thursday, with the team stating it is “a highly recommended release.”

The term “spy nodes” is part of the vernacular used in the Monero community. It refers to malicious nodes, groups of nodes, or botnets that have the potential to calculate and match IP addresses to transactions conducted on the network. 

The changes focus on providing greater data protection and node matching protocols, such as an improved peer selection algorithm that works to avoid connecting to multiple nodes in the same range of IP addresses and an increase in the limit of subaddresses (unique one-time addresses) that can be created at once. It also includes some general reliability and stability fixes.
