It looks like a bug in older variations of Ethereum (ETH) Geth shopper, specifically variations v1.10.07 and earlier, has brought on a cut up.
“Fork between newest geth and older geth on mainnet. Keep away from doing txs for awhile until confirmed, except you’re certain you’re submitting to newest geth,” tweeted Yearn Finance Founder Andre Cronje, advising: “Go for a stroll exterior, all of us want it.”
Per ethernodes.org, Geth is the most well-liked Ethereum shopper that accounts for 74.63% of the community nodes. Out of those, over 72% of Geth nodes are working older variations of the shopper, which means that the bug might have an effect on roughly 54% of Ethereum nodes. An address has additionally been identified by The Block Analysis because the handle that exploited the bug.
The bug might result in double spend exploits the place customers spend cryptocurrency however the transaction is overwritten on an alternate chain.
Polygon (beforehand – Matic Community) mentioned that the majority most validators have already upgraded to the newest Geth/Bor model on the Polygon PoS (proof-of-stake) mainnet. “The workforce is monitoring the community for now,” they said.

The bug was initially discovered someday previous to August 24, 2021, and was instantly shared and acknowledged by the Go Ethereum workforce. Sentnl, the workforce who found the bug throughout Telos EVM audit, mentioned that the bug was “of a excessive severity” and demanded an “emergency sizzling patch.”
Go Ethereum builders then launched a patch on August 24 but it surely works solely for individuals who have since up to date their node.
None of them will ask their customers to improve their nodes although.:thinking_face:
PS: Improve your Geth nodes to 1.10.8! :raised_hands:https://t.co/n2LHAr09dA

All Ethereum node runners are inspired to replace their Geth purchasers to v1.10.8.
That is nonetheless a creating story.
At 15:23 UTC, ETH is buying and selling at USD 3,248. It is up 4.3% in a day and three.3% in per week.
It seems that someone found the bug we fixed in @go_ethereum v1.10.8 and exploited it inflicting all geth nodes with earlier variations to separate from the community. In case you are working v1.10.7 or earlier please replace!!!

Not serious for ethereum. The majority of miners are on the updated geth that is not exploitable and longest chain is operating as expected.
For other chains that have forked versions of geth, things could get weird https://t.co/1xfYkxo5lR
