ETH News: Ethereum’s Glamsterdam Test Gets Last-Minute Fix Before Major Capacity Jump
Prysm version 7.2.1 adds the new setting as developers test whether validators can handle blocks more than three times larger.
- Offchain Labs released Prysm version 7.2.1 late Monday, hours before Glamsterdam activates on Sepolia, ensuring validators automatically propose 200 million gas blocks when the upgrade goes live on Tuesday.
- One part of Tuesday's test raises Sepolia's gas limit from 60 million to 200 million, giving Ethereum developers a public environment to see how validators cope with substantially more computation inside each block.
- Validators using previous software versions would have defaulted to 60 million gas, potentially diluting the test; version 7.2.1 removes that step by adding the schedule directly to the client.
- The Ethereum Foundation describes the upgrade as part of its scaling roadmap, incorporating EIP 8037 to manage state creation costs, though the Sepolia test does not raise Ethereum mainnet's gas limit.
- Glamsterdam serves as Ethereum's next major upgrade, activating first on Sepolia where developers rehearse protocol changes; Ethereum mainnet still has no confirmed Glamsterdam activation dates.

Ethereum is testing how much cheaper block space it can safely create
Ethereum has prepared to test a 200 million gas limit on Sepolia under the Glamsterdam upgrade, putting more than three times the network’s previous block capacity through a public test before developers decide what could eventually work on mainnet. According…
From 60M To 200M Gas: How Ethereum's Glamsterdam Fork Tests The Limits Of Block Capacity And Decentralized Coordination
On October 6, 2026, Ethereum reached one of the more consequential milestones in its recent scaling roadmap. At approximately 13:53 UTC, the network’s Sepolia testnet activated the Glamsterdam upgrade — and in doing so, it began an experiment that could eventually redefine how much work a single Ethereum block can contain. The fork did not go entirely to plan, however. In the hours leading up to activation, developers with the Prysm client — one…
Glamsterdam on Sepolia: Ethereum Tests 200M Gas Limit
Ethereum activated Glamsterdam on the Sepolia testnet at 13:53:36 UTC on October 6, letting validators lift the block gas limit target from roughly 60 million to 200 million and putting more than three times the network's previous capacity through a public stress test. The Prysm consensus client released version 7.2.1 on October 5, one day before activation, so validators automatically propose blocks at the 200 million setting once the fork trig…
