Regarding autoprecompiles enablement (or any static code analysis effort). Would it be realistic to require quest programs to provide basic-block annotations?

In my experience it shouldn't be needed (in the specific case of current autoprecompiles)

We should consider integrating zkboost-client into CL clients.
- Justin Traglia
Replying to "We should consider i..." Can chat about this async.
- Justin Traglia
So we don’t need another 3rd party piece of software.
- Kevaundray Wedderburn
Replying to "We should consider i..." I think for verification it makes a lot of sense
- Francesco Risitano
@Justin Traglia the idea is that a validator A can equivocate. They can send an invalid proof to node B and send a valid proof to node C. Node B will now reject all proofs from Validator A so even if node C forwards the valid proof to node B they will reject it. Therefore there is a discrepancy / lack of consensus on what proofs are valid.

How do we envision the HW usage ramping over time as new GPUs are released?
- Guillaume
who has access to these clusters ?
- Stefan Starflinger
Replying to "How do we envision t..." What do you refer to with usage, how well zkEVM utilizes the GPU compute resources?
- Ladislaus
https://zkevm.ethereum.foundation/blog/cryptography-research-update
- Kevaundray Wedderburn
Replying to "who has access to th..." Currently it will be pandaOPs + EF zkEVM team
- Yi Sun
Replying to "How do we envision t..." E.g. would we move to 6090 when released
- Stefan Starflinger
Replying to "How do we envision t..." I assume new GPUs will always be around 10-10% more efficient and it would make sense over time to replace old hardware with new hardware.

- Justin Traglia
Replying to "@Justin Traglia the ..." Hmm I see. This is a problem because provers cannot currently be slashed. Alternatively, we could allow/verify proofs from other peers if the proof is different, even if you received a bad proof before. There’s some level of trust that peers have successfully verified before forwarding. I’m a little worried that having everyone re-sign a 300KiB message will be a waste of resources.
- Francesco Risitano
Replying to "@Justin Traglia the ..." Is the message size significant? I would assume you just sign a root?
- Manu
Replying to "We should consider i..." Ideally the BN should call a lib for the verification, like done with the KZG lib.
- Justin Traglia
Replying to "@Justin Traglia the ..." Oh, is that it? Maybe that’s not so bad.
- Justin Traglia
Replying to "We should consider i..." I agree.
- Francesco Risitano
Replying to "We should consider i..." Yeah I think we can integrate proof verification into the proof engine
- Kevaundray Wedderburn
Replying to "We should consider i..." Yeah I agree, right now its easier to have this docker for ease of development and versioning
- Francesco Risitano
