According to BlockBeats, Andreas Kohl, co-founder of the Bitcoin sidechain Sequentia, has claimed responsibility for disrupting 69% of the Dogecoin network. Kohl stated that he executed this operation using an old laptop from El Salvador, exploiting a vulnerability discovered by researcher Tobias Ruck, which led to the crashing of nodes.
Data from Blockchair indicates that prior to the exploitation of this vulnerability, Dogecoin had 647 active nodes. As of the time of writing, the number of active nodes has decreased to 315. This significant reduction in active nodes highlights the impact of the vulnerability on the Dogecoin network's stability and functionality. The incident underscores the importance of network security and the potential risks posed by vulnerabilities within blockchain systems.
