I'd like to bring up the topic of moving the call to eth-o-clock in the future to align with other breakout rooms. The day can stay the same if there's no conflict with the protocol call calendar. Additionally, should we consider increasing the frequency as peerDAS might get more limelight?

[jimmygchen]

I'd like to discuss:

• Schedule for peerdas-devnet-4 launch
• What are the state of KZG libraries? Have both c-kzg and rust-eth-kzg been audited and production-ready? Is the longer term plan to maintain both libraries?

Spec discussion:

• What outstanding work remains on the PeerDAS spec?
  • Validator custody: nodes are required to download all additional columns within the DA window when their CGC increases, do we need to explicitly spec this out?
  • Distributed blob building: do we need any form of this in PeerDAS? if so, what are the minimum requirements?
  • DAS parameters for production: do we need further research in this area? e.g. is 128 column subnets what we should aim for? This may require increasing peer counts in some clients.

Thanks for everyone who joined the breakout call today!

Summary:

• All clients have made good progress and are mostly devnet-4 ready 🎉
• peerdas-devnet-4 will be launched shortly 🚀
• Teams started discussing peerdas-devnet-5 scope and ways to test distributed blob building.
• There were some discussions to add more details to validator custodty and distributed blob building in the consensus spec.
• Pari will start a poll on moving this call to a 3pm UTC from the next call, and change this breakout call to weekly!
