amsterdam upgrade on the Hoodi test network after researchers found that proposed gas-accounting changes could alter how existing smart contracts handle failed transactions. – ChainSecurity found that EIP-8037 and EIP-8038 could leave some contracts with more or less gas than expected, potentially making errors permanent or causing otherwise valid operations to fail. – No replacement date has been announced for the Hoodi test or its planned 200 million gas limit, and Ethereum’s mainnet upgrade date remains unconfirmed. Ethereum developers have called off Monday’s Glamsterdam upgrade on the Hoodi test network after security researchers identified a problem that could change how existing smart contracts handle failed transactions, potentially allowing errors to become permanent
The upgrade was due to activate on Oct. 26 at 17:42:48 UTC. Developers postponed it during Thursday’s All Core Devs Execution meeting to investigate how a proposed change to Ethereum’s gas accounting interacts with contracts already running on the main network. No replacement date has been announced.
The concern centers on EIP-8037, which changes how Ethereum charges for creating new records in its database. The proposal is intended to limit the growth of that database as Ethereum increases the number of transactions its network can process. Security firm ChainSecurity published an analysis on Oct. 13 showing that the change, combined with EIP-8038, could alter how contracts respond when another contract they call runs out of gas, or the fees used to pay the network’s operators.
