#GlamsterdamOnSepolia
About GlamsterdamOnSepolia
Ethereum’s Glamsterdam upgrade activated on the Sepolia testnet on Oct 6, marking a key step before mainnet. It introduces enshrined proposer-builder separation (ePBS) and block-level access lists (BALs) to support L1 scaling. Sepolia’s gas limit was raised from about 60M to 200M for testing; Ethereum mainnet’s gas limit has not been raised to 200M. Activation dates for Hoodi and mainnet remain undecided.

Ethereum’s Glamsterdam test runs near 200 million gas per block after upgrade
The Sepolia rehearsal has raised its processing budget more than threefold, but sampled blocks used less than half that allowance.

Key News & Narratives
· Ethereum's Glamsterdam Testnet: The biggest upgrade since The Merge goes live on Sepolia today, bundling EIP-7732 (enshrined PBS) and EIP-7928 (parallel processing). Mainnet targets Q4 2026.
· Macro Backdrop: September NFP came in at just 29K vs 90K expected, cutting October rate hike odds. However, the 10-year Treasury yield holds near 5.25%, keeping pressure on risk assets.

Glamsterdam activates on the Sepolia testnet today, testing changes to how Ethereum blocks are built and validated, including ePBS and block-level access lists.
These are meaningful infrastructure changes aimed at improving L1 scalability and reducing reliance on external block-building infrastructure.
Mainnet timing is still undecided.

Ethereum has a live stress test in ~3 hours.
At 13:53 UTC today, Glamsterdam activates on Sepolia. The upgrade rewires block production with ePBS and enables parallel execution groundwork via block-level access lists—while validators can test gas limits as high as 200M.
ETH is $2,694.08 on OKX, +0.23%/24h.
This isn’t mainnet. It’s the rehearsal for Ethereum’s next scaling era.
Sepolia testnet validators: update your nodes.
Today at ~4pm, we’ll see Glamsterdam (Gloas + Amsterdam) go live on Sepolia.
This marks a major milestone for Glamsterdam and for Ethereum more broadly.
Glamsterdam’s main focus has been scaling, but at the same time the fork also reduces trust requirements, improves sync, and harmonizes resource pricing to improve DoS resistance as the chain scales.
It will likely be the largest Ethereum fork since the Merge, and it has been ambitious from the beginning.
ePBS and BALs were selected as headliners early on, and the fork’s theme - scaling - evolved quite naturally from there. When core devs later decided to reprice the EVM as well, the fork’s surface area increased quite a lot and Glamsterdam became a much broader upgrade than initially expected.
That also meant more work across specs, clients, tooling, and testing. Almost a year of benchmarking, implementation work, refining specs, testing and devnets followed, and over time Glamsterdam has really started to harden.
It has also been the first fork where AI played a major role across basically the whole pipeline: research, benchmarking, testing, client implementations, and security audits, which is interesting to witness.
One can clearly feel the accelerated pace at the frontlines: while Sepolia is forking to Glamsterdam, core devs are already busy shipping the first Hegota devnets.
Ethereum is not yet where it needs to be, but we’re getting there. Fork after fork, the chain becomes more scalable, more robust, and more capable.
And with post-quantum security likely becoming one of the main focus areas over the next few years, there is still a lot ahead.
