ACDC #182 · EIP-7928 included Devnet7 confirmed
AllCoreDevs - Consensus #182 · 2026-07-09
Tony's block access list change will be included in devnet7
Agreed to include Tony's block-access-list change and progressive containers in Glamsterdam devnet7 and launch it early next week. The ePBS-related API and the circuit breaker design were also made more concrete.
Why it matters
With devnet7 confirmed for early next week, the main Glamsterdam execution layer changes begin to be validated on a real network. The aim is to buy the ecosystem preparation time by announcing a public devnet targeted for early August, where apps and staking operators can test changes such as repricing ahead of time.
Decisions
- Block access list included: Tony's block-access-list (EIP-7928) change will be included in devnet7 rather than pushed to devnet8. It is a small change, and the clients judged they could incorporate it within a few days.
- Progressive containers: Confirmed that progressive containers will be included in devnet7. Local testing is proceeding with them included.
- Removing blinded payloads: Remove the blinded execution payload from the stateful flow of Produce Block v4. It adds a lot of complexity for a small performance gain, so it is being dropped.
- Gloas public devnet: Targeting early August for a public devnet for testing Gloas apps. It lets apps and staking operators test changes such as repricing ahead of time.
Discussion
Whether to include the block access list change in devnet7
The first issue of the day was whether to include Tony's block-access-list (EIP-7928) change in devnet7 or defer it to the next devnet.
Outcome: Confirmed 00:22:48
ProduceBlock v4 per-builder authentication and configuration (PR #625)
Asked for ecosystem feedback on Beacon API PR #625, which aims to standardize how validators send authentication to builders as block production changes under ePBS.
ePBS circuit breaker approach
The circuit breaker, which falls back when a builder does not release the payload, is a per-client implementation matter, so each team shared which approach it would take.
Debate over the execution payment field in bids
Over the field that carries the execution layer payment a builder promises in the CL block, the Lido side raised the question of whether it is right to put an unverified value on-chain.
