Should have an update on 4444s based on the outcome how client teams weigh in on this document: https://notes.ethereum.org/M41Oj3WyRVSC36Rr0c-Tjg

[protolambda]

I would like to propose a simple change to EIP-7702, before it is too late and the Pectra spec is frozen: change the auth.chain_id size limit back to uint256.

This is key to enable future more interoperable chain configurations and elastic chain instantiations, by binding the identity to the config/pre-state of the chain. And other ethereum protocol rules allow uint256 chain IDs, so why start arbitrarily limiting them here?

See eth-magicians comment for more context: https://ethereum-magicians.org/t/eip-7702-set-eoa-account-code/19923/326

I'd like to revert removal of NewBlock(Hashes) in eth/69: ethereum/EIPs#9133

[CarlBeek]

I'd like to discuss EIP-7808 with reserves half of the Tx-Type range for use by the RollCall process. (Much like we did with EIP-7587 for precompiles.)

[0xwormhole]

I have extended the technical specification for EIP-7503 in this pull request: ethereum/EIPs#9080

I cannot participate in the call directly. I would appreciate feedback from core developers on my changes. Is the proposed implementation plan satisfactory? What should be changed or improved?

I am not an expert in cryptography. I cannot provide a complete implementation of this part of the EIP. How should we proceed?

What is the process for including these changes in an Ethereum hard fork?

Thank you!

Alternative proposal for removing chain_id in EIP-7702 authorization tuple: ethereum/EIPs#9152

[MarekM25]

I want to provide an update regarding the changes in EIP-2537.

Gas costs updates:

• EIP-2537: Gas pricing MAP, MUL and ADD operations
• EIP-2537: Gas pricing pairing operations
• EIP-2537: MSM gas repricing

And discuss the decision about EIP-2537: Remove redundant MUL precompiles. This PR has support from the six people involved in the BLS discussion. If there are no objections, we should proceed with merging it

[dcrapis]

I would like to announce a working group that Ansgar and I are starting in January to coordinate a benchmarking effort on EVM opcodes and resources.

We want to update resource consumption approximations from the table that was initially used to set gas costs, in a more principled way. This will enable changes to opcode costs and also contribute to our ongoing research on a multi-dimensional fee mechanism.

Ansgar will also introduce related topics that we can also potentially address in the working group (refund structure, access list and state warming at the block level).

[timbeiko]

@pipermerriam @protolambda @yperbasis @CarlBeek @0xwormhole @fjl @MarekM25 @dcrapis I've added all your agenda items in order of urgency. Hopefully we manage to get through all of them on the call!

[arnetheduck]

ethereum/consensus-specs#4064 is relevant for the group of execution client developers - specifically, an option to put a limit on the size of the transaction list in an execution payload is being considered.
