Ethereum delays Glamsterdam test after security devs flag risk to existing contracts

Ethereum core developers officially called off the Monday launch of the Hoodi testnet after security researchers highlighted critical flaws in the upcoming Glamsterdam upgrade. The problematic code involved new gas rule modifications that could inadvertently allow smart contracts to permanently log and store failed operational states on-chain. Demonstrations by audit teams proved this vulnerability could introduce unforeseen edge cases and data bloat across multiple active decentralized applications. By halting the testnet rollout, developers prevented a potentially dangerous configuration from propagating to more advanced staging environments. The decision underscores the complexity of implementing low-level gas optimizations without destabilizing legacy smart contract compatibility. The community will now re-evaluate the gas logic changes and establish safer implementation pathways for future testing iterations.
