EIP-4844 Implementers' Call #5

[gakonst]

Code here https://github.com/gakonst/stress4844, tested for 128KB, blocked on finding an MEV Boost builder for 512KB/1024KB etc.

I've been spamming https://goerli.etherscan.io/address/0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa from https://goerli.etherscan.io/address/0xf5f02208279382cb8e6af943dafa8eac418bbdd3.

After 5930 I think we can update the EIP to "review" status. Any objections?

It might be fruitful to spend a few moments discussing whether we want to make sidecars optional when a block has no blob transactions. We have a cryptography PR which fixes an issue presented when this happens: ethereum/consensus-specs#3093

However, if other subsystems would benefit from sidecars being optional, we might be able to set stricter invariants in the cryptography library as well.

One more (hopefully last) spec PR update:

• ethereum/EIPs#5862
  Given that this remains controversial and that we will start with a lower throughput anyway, my recommendation would be to stick with a min data gasprice of 1 and close this PR.
• ethereum/EIPs#5864
  Merged. Ended up going with padded return data, to match the style of existing precompiles.
• ethereum/EIPs#5930
  Waiting for a final review, should hopefully be merged by the time of the call. Blob transactions are only announced, not broadcast.
• ethereum/EIPs#6020
  For completeness: Specifies that excess_data_gas starts at 0 at the fork.

That is super interesting, could you expand on this a bit what this stress test actually does? Does it simulate a (modified) devp2p network? Locally? Distributed? Or does it somehow interact with an existing network simulating an increased load with some tricks?

Anyhow: pretty cool! 🙂 💯

• [EIP-4844] Return Modulus From Precompile EIPs#5864
  Merged. Ended up going with padded return data, to match the style of existing precompiles.

For completeness: Just merged a tiny additional PR to clarify that the return data follows usual EVM big endianness:

• ethereum/EIPs#6026

Closed in favour of #679
