A major consensus bug has affected more than half of the nodes on the Ethereum network, causing those running older versions of Geth to be separated from the mainnet.
According to Ethereum software developer Marius van der Wijden, an attacker took advantage a vulnerability affecting older versions of Geth, one of Ethereum’s software clients. According to the developer, Geth clients and Ethereum nodes running software v1.10.7 or earlier run the risk of being separated from the network.
“Infura and the big exchanges seem to be on the right side of the fork, so all transactions through metamask should be fine,” said van der Wijden. “Users running validators should update their nodes quickly (in the next 10 hours, I think), otherwise they would vote for invalid committees.”
A chain split has occurred on the Ethereum mainnet. The issue was resolved in the v1.10.8 release announced previously. Please update your nodes, if you haven’t already!
