Ethereum to Test Glamsterdam Upgrade Amid Security Concerns
- A public test of the Glamsterdam upgrade is scheduled for October 6, 2026, on the Sepolia testnet.
- The upgrade aims to increase the block gas limit to approximately 200 million, enhancing transaction capacity.
- Developers warned that attackers could exploit fake builder identities in block auctions, potentially disrupting network operations.
- Client teams have until September 29 to ensure compatibility with Sepolia before the test fork.
- A follow-up public test on the Hoodi network is tentatively set for October 27, pending results from Sepolia.
The upcoming Glamsterdam upgrade represents a significant step in Ethereum’s development, following previous upgrades like Fusaka and Pectra. The potential vulnerability in Sepolia’s auction system highlights the need for robust testing before broader implementation.
