According to Cointelegraph, Andreas Kohl, co-founder of Bitcoin sidechain Sequentia, claims he has disrupted 69% of Dogecoin network nodes using an old laptop from El Salvador.
Data from Blockchair shows that before the vulnerability was exploited, Dogecoin had 647 active nodes. Currently, Dogecoin only has 315 active nodes.
Kohl stated that he caused the node crash by exploiting a vulnerability discovered by researcher Tobias Ruck.
