Glamsterdam Hoodi Testnet Announcement

What happened

The Glamsterdam network upgrade is now scheduled for the Hoodi testnet, following its activation on Sepolia on October 6. It advances Ethereum's scaling roadmap with enshrined proposer-builder separation, block-level access lists, and gas pricing changes.

Confirmed

Global impact / market context

These changes aim to make Ethereum handle more activity and price network use more accurately. Block space is how users pay to store data or run code, so new pricing rules could change what developers and companies pay to build on Ethereum.

Analyst inference

Testing on Hoodi follows the Sepolia activation, showing the upgrade is moving through Ethereum's final trial stages before any main network release. This matters for ETH holders and teams that depend on Ethereum's fees and processing speed.

Analyst inference

What to watch

1. Watch the Hoodi testnet run the Glamsterdam upgrade and see whether its new gas pricing and access list features work without errors. Confirmed
2. Watch for a future main network activation date, since a successful Hoodi test would be the final step before real users face the changes. Proposed
3. Watch whether developers change how they build applications if block-level access lists lower costs and enshrined proposer-builder separation alters who can produce blocks. Analyst inference
