ACDC #185 · EIP-7610 Excluded from Glamsterdam

AllCoreDevs - Consensus #185 · 2026-08-20

Drops an EIP that only added performance burden, and EIP-8253 solves the problem instead.

EIP-7610 was officially cancelled in Glamsterdam, and four EIPs, including EIP-8253 which replaces it, were accepted as candidates for the next fork, Hegotá. Testnet fork dates were also proposed for the first time: Sepolia on September 28 and Hoodi on October 26.

Why it matters

With testnet fork dates proposed, the Glamsterdam mainnet rollout is coming into view. If Sepolia, the dapp-focused testnet, forks first, application developers can test the gas repricing changes ahead of time.

Decisions

Discussion

Can the builder deposit cache be trusted across a fork transition

Six hours before the call, when the Gloas fork activated on devnet 8, several clients stalled on cache problems while processing about 16,000 builder deposits, and a debate began over whether the same design is safe on mainnet.

EIP-8379: can the Engine API be optional

The Nimbus side proposed an Engine API extension that makes the CL the single source of truth for sync as a Hegotá candidate, and the question became whether it can be an optional implementation like other networking EIPs.

Outcome: PFI decision 00:54:23

Does the CL block retention period need to be reduced

A proposal (EIP-8383) emerged saying that the constant underlying the retention period should be halved because of the introduction of EIP-8061 in Glamsterdam, but opinions split from the start on why it should change at all.

Outcome: PFI decision 00:54:23

Hegotá tier rankings: the same A means different things

All client teams agreed to publish their Hegotá candidate EIPs sorted into S/A/B/D tiers by mid-September, and how to read the tier labels immediately became a point of debate.
