A bug in Geth causes a fork

A major consensus bug has affected over half of the Ethereum network’s nodes, resulting in those operating the older versions of Geth splitting from the main blockchain. Ethereum software developer Marius van der Wijden revealed that an unknown group or individual exploited a flaw affecting earlier versions of Geth.

 

Wijden pointed out that as a result of the bug, Geth clients and Ethereum nodes running software v1.10.7 or earlier are also at risk of splitting from the main network. He added that users that validators need to update their nodes over the next few hours. Failure to do so would cause them to vote on invalid committees.

The vulnerability current affects older versions of Geth clients, mostly v1.10.7 and earlier. These versions represent roughly 75% of all Ethereum nodes. Furthermore, at least 73% of Geth clients are operating the older versions. As such, roughly 54% of Ethereum nodes are currently operating with a major infrastructure bug.

Some market analysts are concerned that the bug could result in double-spending attacks on the Ethereum network. Yearn.finance founder Andre Cronje warned users to be careful at the moment. “Stay away from doing [transactions] for a while till confirmed, unless you are sure you are submitting to latest Geth,” Cronje said.

This bug is a major deal for the Ethereum network

The Ethereum network has been previously threatened by software bugs, but this latest one is one of the biggest to ever face the blockchain. Although some nodes have split off from the main network, there are no consequences to that action at the moment.

Currently, it seems most Ethereum miners are operating updated versions of Ethereum. Thus, implying that the network hash rate is supported by the longest chain. The nodes still using the older Geth versions are unable to access the main blockchain. Hence, while there is a possibility of an exploit hitting the Ethereum network, the blockchain appears to be stable for now.

Yes. We've consistently identified winners across multiple cycles. Bitcoin under $1,000, Ethereum under $70, Solana under $10, WIF from $0.003 to $5, PopCat from $0.004 to $2, SPX blasting past $1.70, and our latest pick has already 200X'd since June 2025. Everything is timestamped and public record.

No. When we founded Cryptonary in 2017 the market was new to everyone. We intentionally created content that was easy to understand and actionable. That foundational principle is the crux of Cryptonary. Taking complex ideas and opportunities and presenting them in a way a 10 year old could understand.

Signal vs noise. We filter out 99.9% of garbage projects, provide data backed analysis, and have a proven track record of finding winners. Not to mention since Cryptonary's inception in 2017 we have never taken investment, sponsorship or partnership. Compare this to pretty much everyone else, no track record, and a long list of partnerships that cloud judgements.

We share highly sensitive, time-critical research. Once it's out, it can't be "returned." That's why membership is annual only. Crypto success takes time and commitment. If someone is not willing to invest 12 months into their future, there is no place for them at Cryptonary.
