PSA: the Unknown Payload error code used in the 4844 engine API changed to match the regular engine API unknown payload error code again (we missed an update last year). See https://github.com/ethereum/execution-apis/pull/399/files

If we have a time it would be great to discuss merging getPayloadV3 with getBlobsBundleV1 Engine API methods

Traveling so unlikely to make this. Update: we have tested the following on devnet with multiple prsym nodes:

• State transition passes spec tests
• Validators signing and broadcasting blobs
• Nodes Syncing blocks and blobs by range
• Blobs by root on special cases

We should be ready for multiclient devnet

Added @protolambda @mkalinin, and noted @terencechain - TY for the update!

I'm also not going to be able to make it but here is a Lighthouse update:

• Jimmy has been working on testing locally https://hackmd.io/@jimmygchen/H1XUtBIfn
• We're passing deneb EF tests for spec release v1.3.0-rc.5, but this doesn't include the TX type update, it would be good if we could get a CL spec release candidate with all changes we intend to include in the devnet so we can make sure we are passing EF tests
• We're still working on ironing out single block + blob lookups as well as fixing some gossip verification
• We could make 1 week for a devnet target, would prefer 2 weeks

if prysm is ready with the following proposed spec for devnet 5: https://hackmd.io/@inphi/HJZo4vQGn, lodestar/ethereumjs can do devnet with prsym / any other EL

Talking of spec tests, are the new spec tests with 0x03 type version out?

Talking of devnet 5 specs, it would be nice if these PRs could be reviewed/merged:

• Add corresponding proofs to BlobsBundleV1 execution-apis#392
• Update EIP-4844: Decouple blobs EIPs#6610

I also propose optional inclusion of this PR for devnet5:

• Add blob signing endpoints beacon-APIs#302
