World's Second-Leading Crypto Network Ethereum Splits Into Two Chains

The world’s second-largest cryptocurrency network, in terms of market capitalization, Ethereum, saw a chain split today as a software bug affected a large number of full node clients.

World's Second-Leading Crypto Network Ethereum Splits Into Two Chains

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 number of reports and data from analytical web portals show that the Ethereum blockchain has split into at least two versions as a number of Geth nodes did not update to the correct chain. The Twitter communication channel for the Ethereum network called “Go Ethereum” tweeted about the incident on Friday afternoon.

“A chain split has occurred on the Ethereum mainnet,” the Go Ethereum Twitter account said. “The issue was resolved in the v1.10.8 release announced previously. Please update your nodes, if you haven’t already.”

Etheruem developers discovered a vulnerability and subsequently released a patch in mid-August. The patch is called Hades Gamma and it was a “hotfix release to patch a vulnerability in the EVM (CVE-2021-39137).” The blockchain fork, of course, caused it to be a very topical conversation in the crypto universe. For instance, Lucas Nuzzi, tweeted:

The old version of the Geth client is used by more than 70% of the Ethereum network’s nodes. On August 24, the Twitter account Go Ethereum told the public about the upgrade and said: “Heads up. Geth v1.10.8 is out, fixing a security vulnerability in all live versions of Geth. All Geth users need to update. Further details will be provided at a later date to avoid attacks on Ethereum and downstream projects.”
