Monero Developers Release Privacy Upgrade “Fluorine Fermi” Against Spy Nodes
Enhancing anonymity in the Monero network
The Monero (XMR) development team has released a new client update — version 0.18.4.3 “Fluorine Fermi”, aimed at further protecting users’ anonymity against so-called “spy nodes” that attempt to correlate IP addresses with blockchain transactions.The update introduces a redesigned peer selection algorithm, which prevents the client from connecting to multiple nodes within the same IP range — a common tactic used by surveillance networks to de-anonymize transactions.
Technical improvements and stability fixes
In addition to the enhanced privacy logic, developers have increased the subaddress creation limit and implemented numerous stability fixes to improve the overall reliability of the Monero client.The network update builds on Monero’s ongoing efforts to counter deanonymization techniques that exploit network-layer metadata, rather than the blockchain itself.
Dandelion++ integration for advanced privacy
Alongside the client update, the team introduced additional privacy software, Dandelion++, designed to obfuscate the origin of transactions by reshaping how they propagate across the network.The protocol makes it significantly harder for adversaries to link IP addresses with specific wallet transactions, even when monitoring multiple entry nodes simultaneously.
Market reaction and XMR price movement
Following the announcement, XMR’s price briefly surged to $347 — its highest level in three weeks — before settling near $340, according to CoinMarketCap.Analysts believe that the update could strengthen Monero’s position as the leading privacy-centric cryptocurrency amid tightening global surveillance measures.
Conclusion
The Fluorine Fermi update represents another milestone in Monero’s technical evolution, focusing on long-term network integrity and resistance to deanonymization.By integrating solutions like Dandelion++ and improving node selection algorithms, Monero continues to set the standard for privacy in decentralized finance.
