Ethereum postpones Glamsterdam Hoodi testnet launch over security risks
Image: CointelegraphEthereum developers have postponed the Glamsterdam hard fork on the Hoodi testnet after security researchers identified gas-related risks affecting existing smart contracts. The upgrade changes gas pricing for state creation and state access. Reports differ on the Hoodi schedule, with one saying activation was set for October 26 and another saying it was delayed. No mainnet activation date has been announced.
Key points
- Glamsterdam is an Ethereum protocol upgrade that changes gas pricing for state creation and state access.
- The upgrade is being tested on the Hoodi testnet before any mainnet deployment.
- Ethereum developers postponed the Hoodi testnet deployment after security researchers flagged gas-related risks.
- No mainnet activation date for Glamsterdam has been announced.
Why it matters
The delay leaves Glamsterdam's mainnet timeline open, and the flagged gas changes could affect how existing smart contracts handle failed transactions. Developers were told to check their contracts.
What's unclear
One report said the Hoodi testnet activation was scheduled for October 26, while another said the deployment was postponed.
