ACDT#41: Call Minutes + Insights
The call where developers raised concerns about PeerDAS readiness
Good evening,
Today, Ethereum developers shared updates on the launch of Fusaka Devnet-2, which has been pushed back by a day. They also discussed key blockers to PeerDAS and EIP 7907 implementations.
Below is the full call summary for All Core Developers Testing (ACDT) call #41.
(Takeaways on ACDT #41 are featured below for premium subscribers.)
Yours truly,
Christine D. Kim
Fusaka Devnet-2:
Developers were unable to launch Fusaka Devnet-2 on Monday, June 23, as planned in All Core Developers Execution (ACDE) #214 due to a lack of readiness on the part of consensus layer (CL) client teams.
They are now aiming to launch the devnet tomorrow, June 24.
PeerDAS:
Developers discussed a proposed change to the
engine_getBlobsV2
API method, suggested by Ethereum Foundation Researcher Raúl Kripalani, that would help optimize blob propagation at the networking level.Kripalani said he would update his pull request (PR) based on today’s call discussion for further feedback from developers.
Sunnyside Labs, formerly known as Test in Prod, is a core development team of the Optimism Collective. They presented new analysis on bottlenecks and room for improvement in clients with their implementations of PeerDAS.
Developers agreed that further analysis on client bottlenecks is needed before they can set a schedule for increasing the blob capacity in Fusaka. They also noted that to do this analysis, they need to freeze PeerDAS specifications, which they haven’t yet done.
EIP 7907:
Ethereum Foundation Researcher Jochem Brouwer presented benchmarking analysis that he conducted with Geth developer Marius van der Wijden on the impact of larger contract code sizes on client performance. Brouwer said he will add the tests he performed to the shared “Ethereum execution specifications tests” repository. He said further tests on this EIP are needed.
Developers reaffirmed that EIP 7907 still needs to be updated in accordance with the decisions made on ACDE #214, where developers agreed to reduce the contract code size limit in EIP 7907 from 256 KB to 48 KB. This change to the EIP will not be tested in Fusaka Devnet-2. It will go into Fusaka Devnet-3.

The development timeline for PeerDAS is a major unknown impacting Fusaka readiness for Ethereum mainnet.
