ACDC #183 · Devnet-7 EIPs SFI finalized in bulk
AllCoreDevs - Consensus #183 · 2026-07-23
All EIPs slated for Glamsterdam have moved up to the final inclusion stage.
All Glamsterdam EIPs included in devnet-7 were moved to SFI (Scheduled for Inclusion) without objection, and four new EIPs were accepted as candidates for the next fork, Hegotá.
Why it matters
SFI confirmation means the features targeted for Glamsterdam are effectively locked in, and the schedule toward devnet-8 in August and the public testnet in September stays on track. The Hegotá candidates accepted alongside show the direction of next-generation work such as attestation bandwidth savings and post-quantum (PQ) readiness.
Decisions
- Devnet-7 SFI: All EIPs included in devnet-7 are moved to SFI (Scheduled for Inclusion), and a status change PR is opened. This means the Glamsterdam upgrade scope is effectively finalized.
- EIP-8334 bundle: EIP-8334 Bundled Attestation Propagation was accepted as a Hegotá candidate. It is backward compatible, but it will be made mandatory at the fork so that all clients support it.
- EIP-8341 commit: EIP-8341 Partial Execution Payload Commitments was accepted as a Hegotá candidate. Builders commit only to the header fields other than the state root, which buys them computation time.
- EIP-8321 RANDAO: EIP-8321 Hash-Chain RANDAO was accepted as a Hegotá candidate. However, there are strong objections that the iterative post-quantum approach is premature, so discussion continues in the post-quantum Discord channel.
- EIP-8015 cleanup: EIP-8015, removing the deposit and ETH1 data fields, was accepted as a Hegotá candidate. It clears out the outdated deposit-monitoring remnants from before Electra from the state.
Discussion
EIP-8334 Bundled Attestation Propagation
An optimization that saves bandwidth by deduplicating attestation data at the network layer. The proposer first introduced it in order to have it accepted as a Hegotá candidate.
Outcome: PFI decision 00:25:37
EIP-8341 Partial Execution Payload Commitments
A lightweight alternative to the delayed state root, in which the builder commits in its bid only to the EL header fields other than the state root. It was discussed in comparison with EIP-7862.
EIP-8321 Hash-Chain RANDAO
A proposal to replace the BLS-based RANDAO with hash chain preimages for post-quantum (PQ) security. It drew broad debate over whether the iterative approach is right or premature.
Outcome: PFI decision 00:41:51
Engine API REST/SSZ refactoring
It was discussed in order to pick out the eth_ methods that CL clients still need, as Geth rebuilds the Engine API on REST/SSZ.
