Users will now connect to more secure nodes.<\/p>\n<p>General improvements have been added to enhance the network&#8217;s stability and reliability.<\/p>\n<h2 class=\"wp-block-heading\">Guarding Privacy<\/h2>\n<p>As malicious nodes threaten user privacy and contradict the project&#8217;s goals, the Monero community actively seeks solutions: developing security measures, encouraging the launch of personal nodes, and improving software.<\/p>\n<p>At the end of 2024, researchers <a href=\"https:\/\/www.reddit.com\/r\/Monero\/comments\/1hc1ozf\/mrl_recommendation_ban_spy_node_ip_addresses_from\/\">suggested<\/a> that node operators block suspicious IPs and avoid connecting to them. However, this measure is difficult to call effective, as attackers can easily create new &#8220;spy&#8221; addresses.<\/p>\n<p>Another tool promoted by the community is Dandelion++. This software aims to make it more difficult to link IP addresses with transactions.<\/p>\n<p>The issue of Monero&#8217;s privacy came into focus after the <a href=\"https:\/\/forklog.com\/en\/news\/leaked-chainalysis-video-suggests-monero-tracking-method\">leak of a Chainalysis video<\/a> in 2024. In the video, the analytics company demonstrated how it launches numerous nodes in different regions and uses several internet providers to collect IP addresses and transaction timestamps.<\/p>\n<p>In September, the blockchain of the privacy-focused cryptocurrency <a href=\"https:\/\/forklog.com\/en\/news\/monero-experiences-largest-block-reorganisation-in-12-years\">underwent<\/a> its largest reorganization in 12 years.<\/p>\n<p>The mining pool Quibic released a hidden chain that turned out to be longer than the main one.
