- Agnish from Nimbus: implement validator custody with column refill mechanism (link)
- Decision needed on inclusion in peerdas-devnet-7
-
Builder Support (Terence)
- Builders serving as super nodes to help with blob retrieval
- Possibility of adding this to builder specification
-
Roadmap to Fusaka
- Confirm plan: peerdas-devnet-7 → peerdas-devnet-8 → fusaka-devnet-0
- peerdas-devnet-8 to include BPO feature
- fusaka-devnet-0 to be based on devnet-8 spec
-
PeerDAS Breakout Room
- Depreciate this call and cover PeerDAS in ACD(?)
- If so, what is the schedule for making this change?
