Ethereum’s Glamsterdam test gets last-minute fix before major capacity jump
One of Ethereum’s main validator clients updated its software hours before a Sepolia test that will raise the amount of work each block can hold to 200 million gas.

Summary
- Ethereum developers released a last-minute Prysm update to ensure validators automatically produce blocks with a 200 million gas limit during the Glamsterdam upgrade’s Sepolia test.
- Without the update or a manual configuration change, some validators would have continued producing blocks at Sepolia’s previous 60 million gas limit, undermining the capacity test.
- The test will assess whether validators can reliably handle blocks more than three times larger before developers determine an appropriate capacity for Ethereum’s main network.
