The team discussed updates on the upcoming Fusaka fork, with Barnabas reporting successful shadow fork tests showing 100% participation. Dustin provided an update on the Nimbus client bug fix, which is expected soon. The team reviewed the Fusaka mainnet plan and discussed incident response coordination. For Glamsterdam, various clients reported progress on ePBS implementations, with some aiming for late December or early January for devnet testing. The team also touched on the topic of trustless payments in relation to EIP-7732, with Alex noting some community questions about its implications.
The team discussed the inclusion of FOCIL in the Glamsterdam fork and its potential commitment for the HECA fork. While some members advocated for SFI’ing FOCIL for HECA, others expressed concerns about making early commitments and the need to follow the headliner process. The group also debated the current EIP scoping process, with Barnabas suggesting a need to rethink how they decide which EIPs make it into which fork, particularly given plans for two forks per year. The team agreed to continue discussions on FOCIL’s inclusion and the overall EIP scoping process, with further decisions to be made asynchronously.
The team discussed the inclusion of Fossil in Glamsterdam and H-star, agreeing that CFI (Candidate For Inclusion) is the most appropriate path forward given the current process and timeline constraints. They determined that SFI (Softly For Inclusion) would dilute the meaning of the process, while CFI provides a clear path for Fossil to potentially be included in H-star, though not guaranteed. Ansgar emphasized that the core developers’ agreement to include Fossil in H-star is more important than finding the perfect process tool, as any changes to the inclusion would require significant justification.
The meeting focused on the inclusion of FOCIL in the Glamsterdam and HECA events. The group decided to proceed with DFI (Definitely For Inclusion) for Glamsterdam, while leaving the decision for HECA open. They agreed to move forward with the headliner process for HECA in a few months, with FOCIL as a priority. The team also discussed other CL EIPs for Glamsterdam and the need to start testing FOCIL soon.
The team discussed three EIPs related to staking mechanics. They agreed to CFI 8080, which fixes the consolidation queue issue, and to DFI 8071. The decision on whether to also implement 8061, which includes changes to the churn limits, was deferred to a future call. The team also discussed EIP 8062, which proposes a 5 BIPS withdrawal fee for OX01 validators during withdrawals. While some members expressed concerns about the timing and potential negative impact on solo stakers, others suggested waiting until after the Glamsterdam upgrade to consider such changes.
The meeting focused on discussions about validator consolidation and fast finality in Ethereum. Anders emphasized the need for a smaller validator set to improve finality, while Dima and others debated the feasibility of incentivizing consolidation without rewarding larger validators. The group agreed to defer a decision on custom ceilings for 0x02 validators, but Enrico and others expressed concerns about the impact of improved 0x02 features on fast finality. The conversation ended with a proposal to DFI EIP 8062, with the understanding that further work is needed to improve 0x02 and address the challenges of validator consolidation.
The meeting focused on discussing several EIPs related to Ethereum’s consensus and client implementations. The team decided to move forward with CFI (Consensus Finality Improvement) for Fossil and DFI (Distributed Finality Improvement) for Glamsterdam. They also discussed EIP 7688, which adds stable containers to the SSZ spec, and leaned towards including it but decided to take more time to assess its full complexity. The team agreed to revisit the decision on EIP 7688 in the next ACDE call. Additionally, there was some confusion and debate about whether to SFI (Soft Finality Improvement) or CFI Fossil for Heka, which was left unresolved and will be discussed further in the next ACDE meeting.
