Ethereum developers cancelled the Glamsterdam upgrade planned for Oct. 26 on the Hoodi testnet. Security concerns about gas accounting reportedly prompted the move, and no new Hoodi date or mainnet date has been set.
Ethereum developers cancelled the Glamsterdam upgrade scheduled for Oct. 26 on the Hoodi testnet, leaving node operators needing software that will not activate the fork. Ethereum Foundation DevOps contributor Barnabas Busa merged a rollback of Hoodi's network configuration on Oct. 22.
Rollback removes activation settings
The rollback removes the execution- and consensus-layer activation settings. It also drops the scheduled increase in Hoodi's gas limit to 200 million.
However, the cancellation requires changes to software already distributed. An open Besu pull request says Hoodi nodes running version 26.10.0 will still activate Amsterdam, Glamsterdam's execution-layer component, at the original timestamp until they run a release containing the reversal.
Protocol Watch Research & Advisory founder Christine D. Kim told operators: "Revert to an older release without the Hoodi upgrade scheduled", or wait for a new version from their execution-layer client team.
Gas-accounting concerns drive the decision
Kim attributed the cancellation to security issues identified by ChainSecurity. ChainSecurity's analysis focuses on EIP-8037 and EIP-8038, which change state-creation and state-access gas accounting.
According to the analysis, the changes can replenish available gas or alter what the remaining gas can pay for. That can let a contract's failure-handling code finish where it previously would have reverted, turning an operation that should remain retryable into a permanent failure.
No new dates set
The rollback sets no replacement Hoodi date, and mainnet activation was already undecided. Before the cancellation, the Oct. 22 developer agenda said teams aimed to select a mainnet date at the following week's consensus call if Hoodi went smoothly.
