Ethereum Glamsterdam Test Gets Last-Minute Prysm Fix Before 200M Gas Jump
Ethereum’s Sepolia testnet moved to a 200 million block gas limit as part of work on the Glamsterdam upgrade, up from about 60 million. Prysm v7.2.1 was released hours before the test to add the new gas schedule, after a default setting had kept validators at 60 million gas.
What this rests on
What it means
Each sentence links inside to the piece that supports it.
Developers and node operators watching Sepolia will see a test environment handling a much larger execution budget than before, with Prysm updated just hours ahead of the change. That means the immediate focus is on whether clients and validators can work through the higher gas setting now visible on the testnet, not on a mainnet change yet.
In practice, the test changes what Sepolia can process in each block, but the network is not yet showing full use of that capacity in the sampled blocks. The six-minute voting window and the fact that all 32 scheduled blocks were proposed show the mechanics of the test, while the current setup still leaves mainnet unchanged.
What remains open is how far this testnet setting will carry beyond Sepolia, since the live experiment does not commit to the same gas limit on mainnet. What would settle that is a later decision or deployment that sets the mainnet block gas limit, but that is not stated here.
Market reaction
The move was larger before the first headline than after. That is an observation, not an explanation: the market also moves on things nobody publishes.
