A significant consensus bug has affected greater than half the Ethereum community’s nodes, inflicting these operating older variations of Geth to separate from the principle community.
In response to Ethereum software program developer Marius van der Wijden, an unknown particular person or group exploited a vulnerability affecting earlier variations of Geth, considered one of Ethereum’s software program shoppers. In response to the developer, Geth shoppers and Ethereum nodes operating software program v1.10.7 or earlier are vulnerable to splitting from the community.
“Customers that run validators have to replace their nodes shortly (within the subsequent 10h I believe) as they might in any other case vote on invalid committees,” stated van der Wijden.
A series cut up has occurred on the Ethereum mainnet. The problem was resolved within the v1.10.8 launch introduced beforehand. Please replace your nodes, if you have not already!

Binance Good Chain’s Twitter account and others had beforehand warned Geth shoppers to replace to v1.10.8, which claimed to have a hotfix for the vulnerability within the earlier variations. Ethereum Digital Machine- or EVM-compatible chains might also be in danger. In response to information from Ethernodes.org, 74.6% of all Ethereum nodes are operating Geth, with solely 28.4% of Geth shoppers at the moment operating v1.10.8, which means roughly 53% of all nodes on the community are doubtlessly in danger.
“Avoid doing [transactions] for some time until confirmed, except you might be certain you might be submitting to newest Geth,” suggested Yearn.finance founder Andre Cronje

Although software program bugs have beforehand threatened nodes on the Ethereum community, this incident appears to be one of many greatest affecting a serious blockchain. In August 2020, roughly 12% of the community’s nodes had been unusable after a bug compromised half of the Parity nodes and all OpenEthereum nodes.
On the time of publication, the worth of Ether (ETH) appears to be unaffected by the cut up. Knowledge from Cointelegraph Markets Professional exhibits the ETH worth is $3,241, having risen greater than 4% within the final 24 hours.
