A bug on the Ethereum blockchain’s most popular software client, Geth, has created a fork in the network. This means that the Ethereum blockchain is currently processing two chains simultaneously, which—if unresolved—could potentially cause a double-spend attack.
A double-spend attack means that the same cryptocurrency is spent twice, essentially turning a cryptocurrency into a counterfeit, inflating the asset and lowering its value.
The bug in question is only present in older versions of the client, or those that came before the Geth v1.10.8 update. The update is also called “Hades Gamma.”
Ethereum developers previously disclosed this bug on August 18.
PSA: On Tuesday Aug 24th, Geth will issue a hotfix to a high severity security issue. Please make any necessary preparations to upgrade to the upcoming release (v.1.10.8). #ethereum #geth
