Glamsterdam Hardfork Tracker

Glamsterdam is the next planned Ethereum hardfork after Fusaka. This page is a running tracker for everything ETH Daily is following — scope, headliner EIPs, devnet status, the post-fork gas-limit path, and the multi-year push toward faster finality. Updated as devnets ship and new EIPs are added or removed.

What Is Glamsterdam

Glamsterdam follows Fusaka and pairs two execution-layer headliners — Enshrined Proposer-Builder Separation (ePBS) and Block-Level Access Lists (BALs) — with a basket of supporting EIPs covering state-creation gas repricing, a new gas-limit schedule, and groundwork for private and frame transactions.

The fork's combined effect is to:

• Move proposer-builder separation into the protocol via ePBS.

• Make execution parallelizable at the block level via BALs.

• Reprice state-creation gas so a higher block gas limit doesn't translate into unbounded state growth.

• Open the gas-limit path to a 200M floor after Glamsterdam.

• Lay groundwork for the longer-term move toward under-10-second finality.

Mainnet activation has not been scheduled. Devnets are in flight; All Core Devs is iterating on scope.

Headliner EIPs

EIP-7732 — Enshrined Proposer-Builder Separation (ePBS)

ePBS moves the proposer-builder split into the protocol, replacing the out-of-protocol MEV-Boost relay model. It is the first headliner scheduled for Glamsterdam and is the prerequisite that unlocks the higher post-fork gas limit.

EIP-7928 — Block-Level Access Lists (BALs)

BALs make a block's storage access pattern explicit, enabling parallel execution and lowering the cost of re-execution for full nodes and provers. See the ETH Daily Block-Level Access Lists explainer.

Supporting EIPs

Declined / Deferred

• FOCIL (Fork-Choice Enforced Inclusion Lists) — declined for Glamsterdam, deferred to Heka. See FOCIL Declined For Glamsterdam.

Devnet Status

The Glamsterdam devnet series is run by ethpandaops, combining EL features from bal-devnet-* with CL features from consensus-specs alpha releases.

• devnet-4 is the current head, combining consensus-specs alpha-8, bal-devnet-7, and the new Engine API targetGasLimit path used by clients to coordinate the post-fork gas limit ramp.

• Earlier devnets (1–3) integrated BALs, ePBS scaffolding, and the EIP-8037 state-gas reprice.

With devnet-4 head stabilization confirmed following the Platåberget testnet activation, Glamsterdam activated on Sepolia on October 6, 2026, at 13:53 UTC at epoch 353,024 and finalized at 14:24 UTC. Hoodi on October 26 and mainnet as soon as December 2 remain tentative pending confirmation. Read the Sepolia activation report. While Glamsterdam focuses on execution primitives like BALs and ePBS, deferred headliners including FOCIL and Frame Transactions (EIP-8141) transition forward to Hegotá. Live dashboards are maintained at ethpandaops; ETH Daily updates this section as each new devnet ships.

Gas Limit & Throughput

Core devs agreed to target a 200 million gas limit floor after Glamsterdam. The path is unlocked by three interlocking changes:

• ePBS makes higher gas limits operationally viable by enshrining the builder role.

• BALs make execution parallelizable, keeping verification cost manageable.

• EIP-8037 reprices state-creation gas so the higher limit doesn't blow out state growth.

Finality Direction

Glamsterdam is a step on the longer roadmap toward decoupled consensus and faster finality. Ben Edgington's Upgrading Finality blog series lays out a practical path from ~1,000-second finality to under 10 seconds; ETH Daily's recap is Ethereum Targets 10-Second Finality.
