Ethereum developers have postponed the Glamagate testnet upgrade, which was scheduled for October 26, after security researchers raised concerns about potential risks to existing smart contracts.
The upgrade, known as Hoodi, was intended to implement new gas rules as part of EIP-8037. However, researchers discovered that these changes could allow smart contracts to permanently record failed operations, posing a significant security risk.
Multiple outlets, including CoinDesk and Crypto.news, corroborate that the decision to delay the upgrade was made after these security concerns were brought to light. While CoinDesk highlights the specific issue of failed operations being recorded, Crypto.news focuses on the broader compatibility challenges posed by EIP-8037.
The Ethereum community has been cautious with network upgrades, particularly after past incidents highlighted the importance of thorough testing and risk assessment. The Glamagate upgrade was part of a series of updates aimed at improving the network's efficiency and security.
As of now, the total crypto market cap is $2.8T, with Ethereum's market cap at $292.34B. Ethereum's price is $2393.21, down 2.16% in the last 24 hours and 1.89% over the past week. The broader market is also down, with 
Bitcoin experiencing a 1.58% decline in the same period. The Fear & Greed Index stands at 50, indicating a neutral market sentiment.
