Door Remote - 06 Oct 2026
Validators on the latest version will start proposing 200 million-gas blocks automatically when Glamsterdam activates on Sepolia at 13:53:36 UTC on Oct. 6.
Blocks proposed at the old limit would have diluted the test, which is meant to show how the network copes with the larger size.
Ethereum has been raising block capacity in steps, testing how far it can go before running a validator becomes too demanding or expensive. More block space can eventually mean room for more trades, stablecoin transfers and other applications before users start competing for space and pushing fees higher.
The 200 million setting applies only to Sepolia, and Glamsterdam has not yet activated on Ethereum's main network.
Tuesday's test will show whether validators can consistently handle blocks more than three times Sepolia's previous default before developers decide how much of that capacity suits Ethereum itself.
