ACDC #190 · EIP-8015 Hegotá Scheduled for Inclusion
AllCoreDevs - Consensus #190 · 2026-10-29
The EIP that cleans up beacon state has been scheduled for inclusion in the Hegotá fork
Scoping for the Hegotá fork wrapped up on this call. EIP-8015 was Scheduled for Inclusion (SFI), four proposals including bundled attestation propagation moved to Considered for Inclusion (CFI), and EIP-8205, the deposit front-running fix, was Declined for Inclusion (DFI).
Why it matters
The candidate list for Hegotá is now effectively settled, so client teams can start implementation and devnet testing. Simulations showed that including bundled attestation propagation and fast payload propagation would halve the bandwidth burden on home nodes and spread large blocks 3 times faster.
Decisions
- EIP-8015 SFI: EIP-8015 (beacon state cleanup) was Scheduled for Inclusion (SFI) in Hegotá. It is a small change that removes unused data from the beacon chain state.
- Handling of 0x00 deposits: The decision on whether to burn the ETH of 0x00 deposits after the fork, or to re-queue the balance as a 0x01 deposit (proposed by Barnabas), was postponed by two weeks. It will be discussed at Devcon and finalized on the next call.
- EIP-8334 CFI: EIP-8334 (bundled attestation propagation) moved to Considered for Inclusion (CFI) in Hegotá. It reduces network bandwidth by sending attestation data in bundles.
- EIP-8383 CFI: EIP-8383 (shorter CL block retention period) was made CFI for Hegotá. It changes a single configuration value to shorten how long nodes keep old blocks.
- EIP-8148 CFI: EIP-8148 (custom validator sweep threshold) was made CFI for Hegotá. It lets validators set their own automatic withdrawal threshold between 32 and 2048 ETH.
- EIP-8411 CFI: EIP-8411 (fast execution payload propagation) was made CFI for Hegotá. It splits large block data into pieces so it spreads across the network faster.
- EIP-8205 DFI: EIP-8205 (deposit front-running fix) was Declined for Inclusion (DFI). Developers acknowledged the problem itself and committed to solving it in the redesign of the post-quantum (PQ) deposit contract.
- Change of moderators: Ben Edgington was nominated as lead moderator of ACDC and Will Corcoran as deputy moderator. This takes effect from the next call in two weeks.
Discussion
How far to specify bid gossip
Two competing PRs fix a bug where builders send a high bid to the network and a low bid directly to the proposer. The call discussed which one to put in the spec.
0x00 deposits after the fork: burn or re-queue
After EIP-8365 blocks creation of 0x00 validators, the call weighed simplicity against protecting funds on whether to burn incoming deposits or leave a reactivation path.
Outcome: Decision postponed by 2 weeks 00:34:21
Deposit front-running: fix now or in PQ
Lido and client teams were divided on whether to prepare for the deposit front-running vulnerability now with EIP-8205, or leave it to the PQ deposit contract redesign that will change things anyway.
Outcome: DFI decision 01:15:09
Bundled attestation propagation and fork transition handling
The call discussed the bandwidth effect of EIP-8334, which bundles attestations in preparation for decoupled consensus, and whether it is worth touching the attestation structure now.
Outcome: CFI decision 00:55:19
