According to a number of reports and data from analytical websites, the Ethereum (ETH) blockchain has split into at least two versions due to a number of Geth nodes failing to upgrade to the proper chain. On Friday afternoon, the Ethereum network’s communication channel, “Go Ethereum,” tweeted about the event. The old version of the Geth client is used by more than 70% of the Ethereum network’s nodes. On August 24, the Twitter account Go Ethereum told the public about the upgrade and said: “Heads up. Geth v1.10.8 is out, fixing a security vulnerability in all live versions of Geth. All Geth users need to update. Further details will be provided at a later date to avoid attacks on Ethereum and downstream projects.”
