- •ePBS circuit breakers should track missing payloads (not beacon blocks); no standardization required, client-specific implementations acceptable — 00:17:01
Highlights
- Client Updates:
- ·ePBS circuit breakers: Prysm uses consensus-block-based breaker (acknowledged as incorrect for ePBS); needs updating to track missing payloads, not beacon blocks — 00:14:46

- ·Glamsterdam mascot vote open; voting closes July 8 — 00:51:37
- Testing Progress:
- ·Pre-fork slashing test planned on devnet-6 just before Gloas fork activation — 00:09:20
- ·EIP-8282 contract constants under discussion: target=8, max=64 preferred over current 32/256; reduces builder withdrawability delay — 00:44:04
- Fork Status And Schedule:
- ·glamsterdam-devnet-6 launched hours ago; Gloas fork in ~40 min; EL: Besu, ethrex, Geth; CL: all except Teku — 00:07:25
- ·glamsterdam-devnet-5 stable for 3 weeks; Lighthouse range-sync bug outstanding; Prysm peering bug resolved — 00:07:33
- ·Spec bug (consensus-specs #5399) confirmed valid by Terrence; patch targeting devnet-7 — 00:10:24
- Eip Proposals Glamsterdam:
- ·EIP-7688 (progressive containers): 3 clients yes (Nimbus, Lodestar, Lighthouse), 3 maybe (Prysm, Teku, Grandine); targeting devnet-7; DFI deferred — 00:26:52
- ·EIP-8080 (consolidation exit mechanism): DFI'd; authors encouraged to re-propose for Hegota — 00:35:14
- ·EIP-8282 (builder execution requests): old contract on devnet-6 for workflow testing; updated contract (fee-per-enqueue) targets devnet-7; external audit post-devnet-7 (~end of July) — 00:42:34
Action Items

Circuit breakers should be client specific imo
- terence
We haven’t even thought about circuit breaker yet
- Justin Traglia
I vote to leave flexible.

We haven’t. But I believe we should some common baseline...

maybe we could have a circuitbreaker breakout 😂

it's different than pre-ePBS because consensus chain doesn't break

If we put more work on the cl, we can start on frames for the el already
- Eitan Seri-Levi
Reacted to "If we put more work ..." with 😂
- Barnabas
Replying to "If we put more work ..." most of the cls are already on the devnet, and we had to delay launch of the devnet due to el’s not being ready just fyi
- Parithosh Jayanthi
Replying to "If we put more work ..." The thing is this EIP solves the 8192 deposit overflow issue as well
- Etan (Nimbus)
Replying to "If we put more work ..." SSZ frames!

Because the constant could just be raised too, super simple with 8282. What this eip solves is stable 4788 proofs

Grandine maybe, it really depends if there will be left enough of time after ePBS works.
- Parithosh Jayanthi
Reacted to "Grandine maybe, it really depends if there will be left enough of time after ePBS works." with 👍
- kasey
IMO if it doesn’t go into devnet-7 it should be in devnet-8, I’m against DFI
- Parithosh Jayanthi
- Greg K | Lido
May I ask why to DFI?
- Dima Gusakov | Lido
But it is good for ETH in general

Reacted to "33% of eth is staked. hold my beer" with 🤪
- Marius Van Der Wijden (M)
In my opinion we should not waste complexity for this "gap". It's just not important imho
- Greg K | Lido
Isn't it important allowing entities to cheat and exit faster than everyone else?
- Greg K | Lido
Especially when some of them create a product out of it
- terence
Replying to "In my opinion we sho..." I tend to agree with this. We should do only if it’s a “strong must have”. But ill leave this decision to whether that’s true
- Francesco
I can repropose but I am not going to champion the EIP, if someone wants to do it go ahead
- Parithosh Jayanthi
- Marius Van Der Wijden (M)
If clients have not looked into it at all we should dfi it
- Nico Flaig
it's on devnet-6 already

We do need to slash validators on devnet5 right
- Dima Gusakov | Lido
Replying to "We do need to slash ..." There are a few slashed on devote-6
- Dima Gusakov | Lido
Replying to "We do need to slash ..." So it will be tested there
- Francesco
Re: 8080, iirc this was discussed at interop mainly. The call transcripts have essentially nothing about it
- Justin Traglia
I support setting target=8, max=64.
- Toni Wahrstätter
Sounds like a good trade off
- Parithosh Jayanthi
Replying to "Re: 8080, iirc this ..." Thank you! I was just frantically searching where that was too
- Parithosh Jayanthi
Replying to "Re: 8080, iirc this ..." We can prep some doc indicating the issues then by next acd
- Kevaundray Wedderburn
Do we have a date for when we want to freeze changes and then start/finish external audits for 8282?

it would be 3 constants?
- Justin Traglia
Replying to "it would be 3 consta..." The 3rd one is in the consensus-specs.
- Barnabas

Replying to "Do we have a date fo..." so probably end of Jul

Sounds a but brittle tbh

I would rather replace the contract

maybe pr against the sys contract repo?

How often do we expect a single builder to deposit?

- Toni Wahrstätter
64 sounds like more than enough
- Nico Flaig
Reacted to "I support setting ta..." with 👍
- Justin Traglia
Replying to "Sounds a but brittle..." My opinion is that dynamic limits are probably not necessary. I think it’s unlikely that we’ll change them later. It just took us a while to decide on the values.
- Justin Traglia
Reacted to "64 sounds like more ..." with 👍
- Nico Flaig
Replying to "64 sounds like more ..." to be clear that's the max, the target=8, but the expected rate of builder deposits in the normal case is likely far below 1 per payload
- Justin Florentine (Besu)
LUCID needs CL oversight!
- Toni Wahrstätter
Replying to "64 sounds like more ..." Right. I think that's fine
- Barnabas
Devnet 7 spec sheet is up: https://notes.ethereum.org/@ethpandaops/glamsterdam-devnet-7
- Toni Wahrstätter
Replying to "64 sounds like more ..." Maybe we could set the target to idk 16 or 32. What matters is that it's capped

Key decisions
EIP-7688 (progressive containers) targeted for devnet-7; not DFI'd; revisit if devnet-6 instability warrants it
devnet-7EIP-8080 (consolidation-based exits) DFI'd from Glamsterdam; authors may re-propose for Hegota
DFIePBS circuit breakers should track missing payloads (not beacon blocks); no standardization required, client-specific implementations acceptable
