New minor crypto PR just dropped: ethereum/consensus-specs#3214

KZG libraries should adapt their codebase (c-kzg-4844 is already conformant)

[terencechain]

I want to confirm again what goes into eip4844-devnet 4. Consensus spec v1.3.0-rc.1 which includes:

Consensus layer

• gwei for withdrawal amounts for engine api
• historical summaries
• genesis fork version for bls changes

Execution layer

• gwei for withdrawal amounts for engine api
• make engine_getPayloadVN fork agnostic
• EIP-6122 : Forkid checks based on timestamps
• EIP-4895 : Withdrawals
• EIP-3651: Warm COINBASE
• EIP-3855 : PUSH0
• EIP-3860 : Limit/meter initcode

Did I miss anything?

[terencechain]

Also a preliminary 👍🏼 on eip4844-devnet4 timeline. Next Monday is good? or we want it before that

[timbeiko]

@asn-d6 @terencechain added both to the agenda!

Would like to bring this one up as well: ethereum/execution-apis#355

I'm not sure if this is already implemented in the 4844 versions EL clients, but in Lighthouse, we'd like to call the same endpoints through the fork.
