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.
