Ethereum’s upcoming Glamsterdam upgrade clears rehearsal for a big jump in capacity
The test network raised its limit on work per block toward 200 million gas as developers prepare for a proposed October 6 public test.

Ethereum’s latest rehearsal for its Glamsterdam upgrade continued confirming blocks after adopting new block-building rules earlier this week, clearing a key test before a proposed October 6 rollout on the Sepolia public test network.
Nethermind, software used by computers that run Ethereum, followed on Wednesday with a performance test covering one of Glamsterdam’s biggest changes.
Its client completed all 2,302 tests while processing 570.7 billion gas in three minutes and 15 seconds, an average of about 2.9 billion gas per second.
A 200 million limit would let Ethereum absorb more activity before users begin outbidding one another for block space, which could make fee spikes less severe when trading surges or a popular token launch clogs the network.
