Ethereum entered the week with Glamsterdam’s feature set largely decided but its public testing environment still gated by gas benchmarks and cross-client compatibility. In parallel, execution-layer teams began defining what Hegotá might build on top of that foundation.

Glamsterdam and Hegotá are separate forks, but their engineering assumptions are now tightly coupled.

The week in brief

  • Devnet 8 was named Platåberget and designed as a public-facing testnet.
  • The launch remained gated by final gas-repricing benchmarks.
  • Block-Level Access List output still needed cross-client alignment.
  • Eight execution-layer EIPs entered Hegotá evaluation.
  • Client teams continued work on discv5 and node-information compatibility.

Upgrade watch · Glamsterdam

Platåberget was designed to start before Glamsterdam activation and cross the fork after genesis. That makes the transition observable by wallets, validators, and infrastructure instead of testing only a chain born with the new rules already active.

The network would complement—not replace—smaller experimental devnets. A stable public environment and a chaotic engineering environment serve different purposes.

Execution layer

The unresolved work was concentrated in details with broad downstream impact: gas pricing, Block-Level Access List RPC output, node discovery, and Engine API behavior. These are exactly the boundaries where independently developed clients must present one Ethereum to external tooling.

Hegotá horizon

Eight execution proposals entered early evaluation. The themes were more important than the count:

  • Reduce transaction dependencies to support parallel execution.
  • Make gas accounting and proofs easier to interpret.
  • Lower the cost of smart-account deployment.
  • Expose transaction state changes for safer verification.
  • Remove obsolete header structures and selected specialized precompiles.

None of these proposals was approved by entering the evaluation set. Their specifications, security properties, implementation cost, and interaction with Glamsterdam still needed review.

What to watch next week

  1. Final gas benchmark results.
  2. Resolution of Block-Level Access List compatibility tests.
  3. Platåberget’s launch configuration and validator bootstrap.
  4. The close of Hegotá’s consensus proposal window.

Signals reviewed: ACDE #242 agenda and call materials, client compatibility reports, and the Glamsterdam/Hegotá meta-EIP discussions.
