High Severity Ethereum Geth Nodes Crash, ETH Hashrate Drops, ETC Remains Safe
Sunday, an Ethereum miner discovered an error stemming from a memory leak that reduced the RAM usage of Ethereum mining rigs, leading to a sudden drop in hashrate and security levels. Temporary solution. The Ethereum development team quickly responded to the attack by implementing an update called Geth 1.4.12 as a temporary solution. All miners and node operators were advised to update immediately, to refrain from geth nodes running out of memory and crashing on block. According to the Ethereum security alert, the memory bug in geth has been marked as a high severity security issue and is....

The Ethereum platform came under DOS attack yesterday, hours before the launch of Ethereum DevCon 2 conference in Shanghai. The Ethereum community had a small scare yesterday after a bug was discovered on the platform. The bug affecting geth nodes built on Go Programming Language was reported as a security alert of high severity on Ethereum blog earlier yesterday. The bug in Ethereum protocol resulted in the crash of geth nodes following memory issues. The issue surfaced hours before the launch of Ethereum DevCon 2 in Shanghai. The issue was determined to be a DOS attack on the platform,....
The Ethereum community is reeling after what appears to be another attack on the network. All nodes running the Geth client appear to be affected. Geth Nodes Running Out of Memory. Ethereum developer and co-founder Jeffrey Wilcke posted a Security Alert on the official Ethereum blog on 18 September. Geth nodes, he said, were “running out of memory and crashing on block 2283416“. He advised users to switch to an alternate client until the problem is fixed. Geth is the the command line interface for running a full Ethereum node implemented in Go. While Geth clients are not a majority on the....
“Stay away from doing [transactions] for a while till confirmed, unless you are sure you are submitting to latest Geth,” advised Andre Cronje. A major consensus bug has affected more than half the Ethereum network’s nodes, causing those running older versions of Geth to split from the main network.According to Ethereum software developer Marius van der Wijden, an attacker exploited a vulnerability affecting earlier versions of Geth, one of Ethereum's software clients. According to the developer, Geth clients and Ethereum nodes running software v1.10.7 or earlier are at risk of splitting....
On August 31, 2022, Ethereum Classic’s hashrate reached another all-time high (ATH) this year at block height 15,850,811. Ethereum Classic’s global hashpower surpassed the 40 terahash per second (TH/s) region on Wednesday. Despite the fact that the network’s hashrate has risen a great deal, Ethereum’s hashrate remains relatively unchanged with just over 1,000 TH/s dedicated to the network.

Almost immediately after all geth nodes crashed due to an out of memory bug, the Ethereum development team released yet another urgent announcement to miners regarding a computational DDoS attack, which significantly delayed nodes and miners in processing blocks. Jeffrey Wilcke, the Ethereum co-founder and lead developer, released a statement to ask all miners and developers to switch to parity mining instead of utilizing geth nodes, which caused some trouble in authenticating and validating some blocks due to the EXTCODESIZE opcode. Wilcke further explained that the Ethereum development....
