Decisions
- •SFI decisions remain with ACD, not ACDT — 00:24:21
- •DevNet3 EIPs eligible for SFI one week after stability demonstrated — 00:26:16
- •Incomplete EIPs (e.g., 7637 gas repricing) excluded from SFI until finalized — 00:27:43
Highlights
- Epbs Status:
- ·ePBS DevNet0: Prysm/Lighthouse/Lodestar working; Teku cannot sync or propose — 00:17:33
- ·Exits not functional yet; deposits working correctly — 00:18:03
- ·Alpha3 released; DevNet1 will likely use PTC lookahead version (Alpha4) — 00:19:03
- Eip Status Process:
- ·SFI process discussion: Should EIPs move to SFI after successful DevNet? — 00:21:00
- ·Proposed SFI candidates from DevNet2: 7708, 7778, 7843, 8024 — 00:22:41
- ·Decision deferred to ACD; SFI only for stable EIPs without interaction risks — 00:24:39
- Bal Devnet Progress:
- ·BAL DevNet2: ~100% participation achieved; Erigon fixed proposal issues today — 00:10:28
- ·BAL DevNet3: EVM fuzzing breaks clients quickly; hash mismatches across implementations — 00:15:06
- ·DevNet3 blockers: CREATE/CALL operations cause BAL hash divergence in Nimbus/Reth — 00:16:34
- Blob Devnet Updates:
- ·BlobDevNet0: Partial cells spec finalized; Prysm bugs blocking progress — 00:08:28
- ·Testnet rollout planned once clients optimistic; limited validator subset first — 00:09:19

hello

- Barnabas
wouldn’t this be better to do in the breakout room?
- Stefan Starflinger
- FLCL
Are new tests planned?
- spencer
Replying to "Are new tests plan..." We'll have another release but it wont change much. Just a single test case.
- jochem-brouwer
If fuzzing and then network breaks then it means testing coverage is missing?
- FLCL
Reacted to "We'll have another r..." with 👍

Reacted to "We'll have another..." with 👍
- spencer
Replying to "Are new tests plan..." This is the test case mentioned by dragan: `tests/amsterdam/eip7954_increase_max_contract_size/test_max_initcode_size.py::test_max_initcode_size_gas_metering_via_create[fork_Amsterdam-create_opcode_CREATE-state_test-short_one_gas]`
- Toni Wahrstätter
To add to jochem's qu., any specific EIPs that break?
- Stefan Starflinger
Replying to "If fuzzing and then ..." yes and no, not all tests are being passed yet
- jochem-brouwer
Heeft gereageerd op "yes and no, not al..." met 👍
- Dragan Rakita
Reacted to "This is the test cas..." with 👍
- terence
Prysm is not ready yet, we need to merge a PR, give us 2 days
- terence
For exit
- felipe
Replying to "If fuzzing and the..." https://hive.ethpandaops.io/ should we add a run for bal-devnet-3 here to track client status?
- terence
Yes, can we do alpha4
- nflaig
did some updates to our checkpoint cache serving @Barnabas should be fine to add to checkpoint-z again
- Barnabas
Reacted to "did some updates to ..." with 👍
- Stefan Starflinger
Replying to "To add to jochem's q..." 8037 gas accounting causing BAL hash missmatch
- Barnabas
I’d propose SFI-ing: 7708 7778 7843 8024
- Potuz
Reacted to "did some updates to ..." with 👍
- Dragan Rakita
Reacted to "I’d propose SFI-ing:..." with ➕
- Stefan Starflinger
Replying to "To add to jochem's q..." For example: CREATE, CALL-with-value, or precompile calls. Nimbus records different storage/account accesses than geth for these operations. Simple eoatx passes. Only evm-fuzz triggers the divergence.
- nixo
i think if ACDE/C is responsible, we can be a bit more proactive there
- FLCL
Replying to "Are new tests planne..." Ty!

I’d do SFI devnet 3 maybe a week after its been stable
- Barnabas
also I
- Jen
Reacted to "I’d do SFI devnet 3 ..." with 👍
- spencer
Reacted to "I’d propose SFI-i..." with ➕
- Stefan Starflinger
Replying to "To add to jochem's q..." reth: Bug likely in how CREATE/CREATE2 tracks code changes or how storage reads vs writes are classified during contract deployment. The hash is computed by alloy compute_block_access_list_hash() which is shared, so the divergence is in the BAL
- spencer
Will aim to add draft PR to update 7723 aligning on what we have spoke about. Few interactions and in passing devnet etc
- Barnabas
"Fully baked”
- Barnabas
Reacted to "Like this one. Will ..." with 👍
- Barnabas
Replying to "I’d propose SFI-ing:..." 7773 you mean?
- Potuz
how?
- spencer
Replying to "I’d propose SFI-i..." both :)

I see Transfer to room, but it requires room code
