Beacon API PRs #630. Can we merge both before DevNet 8? Jason Vranek / Shane Moore (SSV) / client teams
Sparse blob pool (EIP-8070) Engine API changes mandatory for DevNet 8. Are we going ahead with this plan? There was an update on ACDT that the we might revisit this later — Bosul
DevNet 8 launch readiness & timeline — Stefan has the spec sheet ready; target was early August
Other topics:
EIP-8061 SFI decision — Increase exit/consolidation churn. CFI’d since ACDC #171, implemented and tested since DevNet-1, deferred SFI decision since May 28. Long overdue — can we SFI now? Pooja / testing team
Glamsterdam:
First public testnet timeline - are we on track for september? With DevNet 8(the public devnet) planned for August, any blocking issues? Testing progression on track?
Hegota(1h15m):
Non-headliner EIP submission deadline — TODAY — Window closes August 6. New PFI requests raised on the issue, set the stage for what will happen today (Its a proposal window date, its meant to introduce a topic as a contender for non-headliner in the Hegota. Not CFI/SFI decision today on these EIPs, its merely to introduce the topic and give us the time over the next months to move them from PFI to CFI. For sensitive topics, we will do our best to flag when they are to be discussed.)
The meeting focused on reviewing EIP (Ethereum Improvement Proposal) submissions for the upcoming Hekota hard fork, with discussions covering multiple technical proposals and their potential impacts on the Ethereum network. Key topics included Barnabas’s update on DevNet 7 bugs and the planned launch of DevNet 8, followed by presentations of various EIPs including EIP 8359 for BeaconBlock reporting fields, EIP 8363 for tapered issuance burn (which received significant debate about its timing and approach), and EIP 8371 for distributed blob space reconstruction. The team also reviewed EIP 8142 for BLS column propagation and anti-correlation attestation penalties, with detailed technical discussions about implementation challenges and potential impacts on network performance and security. Multiple participants raised concerns about the timing of issuance-related proposals, with Greg requesting withdrawal of the tapered issuance EIP due to insufficient time for proper community discussion before the Hekota deadline.

The meeting covered several key topics related to Ethereum development. Parithosh led discussions on DevNet updates, where Barnabas reported that most clients except Prism were syncing correctly, and DevNet 8 was planned for launch the following week with a named testnet specification. Hanibu presented EIP 8359 proposing a new BeaconBlock reporting field to improve client diversity tracking, addressing limitations of current graffiti watermarks. Barnabé presented a proposal for reducing slot times from 12 to 10 seconds in the Hegota fork, discussing technical considerations including contract compatibility and infrastructure impacts. The team also reviewed EIPs for VOPS profile eligibility and execution payload propagation in blobs, with Thomas and Camille presenting their respective proposals. Key decisions included moving forward with the slot time reduction proposal and continuing discussions on the technical implementations in follow-up channels.
Kamil and Potuz discussed concerns about EIP proposals affecting block propagation timelines and PTC attestation deadlines. Kamil clarified that execution payload propagation would reuse existing columns while maintaining current deadlines, though the specific implementation details remain to be determined. Csaba presented EIP 8371, proposing to distribute blob space reconstruction work across nodes to reduce CPU load on supernodes and improve system robustness through low-topic notifications and row-based allocation.
Jerome presented EIP-8363, a proposal to introduce a tapered burn mechanism that would reduce the staking incentive once the staking ratio exceeds 50%. He argued that the current endless incentive to stake poses security and centralization risks, and the proposed solution aims to prevent high staking ratios by 2028. Dima and other participants raised concerns about the potential negative impact on small validators and the risk of centralization, questioning the real returns for stakers and the complexity of implementation. Jerome acknowledged the complexity of the topic and invited further feedback, emphasizing the need for a smooth transition if the proposal is implemented.
The meeting focused on discussing Jerome’s EIP proposal regarding issuance curve changes for Ethereum. Key concerns were raised about the timing of the proposal, with Greg suggesting it should be withdrawn for the Jakarta fork due to insufficient preparation time. The discussion included debate about whether solo stakers would be protected under the new proposal, with Oisin expressing concerns about reducing the Nakamoto coefficient. The group also reviewed updates on anti-correlation attestation penalties from Oisin and discussed retiring 0x00 validators from NCEAT, with NC presenting two separate EIPs for this purpose. The conversation ended with a vote selecting the polar bear as the new mascot for Ethereum.
Next Steps:
Bosul: Discuss the EIP 8070 engine APIs purchase update (making V4 and C4 mandatory) in the interop chat on ETH R&D. If no counter-objection by ACDT on Monday, add it to DevNet 8.
Barnabas: Target to launch DevNet 8 early next week, possibly around Tuesday.
Barnabas: Have the DevNet 8 spec up by Monday or Tuesday, on the day of the net launch.
Barnabé: Reach out to big contracts (e.g., Lido, Arbitrum) identified in the survey about hard-coded 12-second slot assumptions.
Kamil: Discuss the EIP 8142 (blob columns propagation) on the peer-to-peer call or on ETH R&D.
Jerome: Consider withdrawing the EIP 8363 (Tapered Issuance Burn) from consideration for Hekota based on community feedback.
Jerome: Answer all comments on the EIP 8363 thread on ETH Magicians.
Oisin: Further discuss and refine the EIP 7716 (anti-correlation attestation penalties) parameters based on community feedback.
NC: Further discuss the proposals for 0x00 BLS validator retirement and balance sunset on ETH R&D.
