Ethereum Faces Chain Split After Node Operators Fail Geth Hotfix Update

Ethereum is making headlines again. It’s been just reported that Ethereum experienced a chain split due to a number of network validators, also called nodes, failing to upgrade their software.

A few days ago, the dev team behind the popular Ethereum software client Geth released an emergency hotfix to a security vulnerability in its code that would have prevented certain users from producing blocks.

Disclosing a vulnerability

The Go Ethereum team had disclosed a vulnerability on August 18.

They said that they would release a patch but did not specify the exact nature of the vulnerability in an effort to prevent an attack:

“The exact attack vector will be provided at a later date to give node operators and dependent downstream projects time to update their nodes and software,” wrote Ethereum team lead Péter Szilágyi on Aug. 24 GitHub patch notes.

It’s also worth noting the fact that in an interview with CoinDesk, Go Ethereum developer Marius Van Der Wijden who noted he was speaking in a personal capacity and not as a rep of the Ethereum Foundation or Go Ethereum, said that after the disclosure an exploit was inevitable.

“I knew that someone would eventually find the bug,” he said. “I just hoped that more people would have updated in time.”

It’s also worth noting the fact that this is not the first time when ETH experienced a chain split due to users running outdated versions of the Geth.

Regarding ETH’s price today, at the moment of writing this article, the coin is trading in the green. ETH is now priced at $3,225.
