Unfortunately, I won't be able to make it this week due to traveling. Here is the pr/issue I'm looking for feedback on. We don't have to bring them up in the call. Aync feedback is also fine 🙏🏼

Small updates on my PRs again:

• [EIP-4844] Reduce Throughput EIPs#5863
  is merged, with the understanding that it might be changed again once we have collected metrics
• [EIP-4844] Return Modulus From Precompile EIPs#5864
  some more discussion around return value encoding. I reached out to the Solidity team for feedback, will make a decision after that.
• Update EIP-4844: Disable Blob Transaction Broadcast EIPs#5930
  new PR, open question: Should it be required behavior to not auto-broadcast blob transactions? EIP-5793 makes this behavior possible, but not mandatory.

Testing / tooling updates

Implementing it this week and will circle back. Apologies for the delay, busy last few weeks.

Our understanding of scope:

• CLI which takes as inputs:
  • Number of blocks to run experiment for (N)
  • Total data to consume per block (len)
  • Chunk size (chunk-size)
  • Private Key with enough ETH to sign the transactions
  • RPC URL that will not drop the transactions
• Logic: Loop N times:
  • Generate len random bytes vector
  • Chunk it to len / chunk-size byte vectors with chunk-size length each
  • Create len / chunk-size transactions: Each byte vec is inserted to the calldata field (NOT 4844 blob related)
• Submit to RPC (or builder to bypass the mempool 128kb limit
