The world’s second-largest cryptocurrency network, in terms of market capitalization, Ethereum, saw a chain split as a software bug affected a large quantity of full node clients. In mid-August, developers discovered a vulnerability and distributed an update called “Hades Gamma” to resolve the problem. However, a large number of full node clients did not leverage the patch and the network forked.
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.
