Pectra – Hoodi

Pari: Validator tests are complete; all intended features have been covered and the network looks stable.
Pari: Noted an orphan block on Sepolia (by Teku); believed to be a one-off, and Teku is investigating.
Sam: Continuing to analyze attestation performance.
Terence (Prysm team):

Prysm updated attestation handling – changes merged.
No bugs reported; focus currently on proposer logic, not full network analysis.


pk910: Cross-withdrawal address consolidation is still pending, but other teams have tested and confirmed it’s feasible.
Pari: Will wait to see if Nimbus corrects attestation packing.
Nico: No notable changes in the last 7 days.
Daniel:

Tested 25k validators on one Lighthouse node.



Specs & MEV Testing

Mario Vega: Specs testing ongoing. Test suites being re-reviewed and executed against all clients. No major issues found yet.
MEV testing is active – consistent stream of MEV blocks being observed.
Partition tool has been used to gather client-side fixes, collected from clients’ retrospective reviews.
Pawan: Diff fuzzer has been running all EF test cases for a week – no crashes so far.
Terence: Mainnet fork date update required in upstream specs.
nflaig: Confirmed that update is likely only needed at:
eth-clients/mainnet/config.yaml
Pari: DevOps team will handle the update in the repo.

PeerDAS

Pari shared link: PeerDAS Devnet 6
Barnabas Busa:

Devnet 6 setup in progress with Kurtosis.
Lighthouse and Grandine clients integrated.
Geth team aware of issues; fix pending.


Marius: Code is fixed but slow; better hardware may help.
Pari: PR submitted by Barnabas to Kurtosis. All spam tools expected to work.
Problabs is analyzing mainnet blob usage; report to be published in coming days.
Marius: Geth does not yet support RPC v2 – patch expected tomorrow.
Barnabas: Asked for clarification – whether the fix relates to a v1 wrapper. Parithosh confirmed it.

EOF (EVM Object Format)

Danno:

Working to roll out specs for EOF.
Test plan (including EEST) will be updated.
EVM 1 is already running EEST.
Having 3 clients running will be nice to have – aiming for more.


ETA for EOF Devnet 1 aligns with Pectra fork timeline.
EOF Devnet 2 will include Opcode changes.
Pari asked if PeerDAS EL version is easy to rebase.

Marius + Roman: Confirmed rebasing is straightforward.


After EOF Devnet 1 is stable, Fusaka Devnet planning will start (Interop, June).
Pari shared: EOF Devnet 1
Livestreaming:

Danno: Shared concerns but agreed livestreaming will be needed eventually.
Async fallback: Use Party Lounge when needed.
