For Cancun: https://eips.ethereum.org/EIPS/eip-6465 (separate from 6404 transactions/receipts)

[timbeiko]

@etan-status should we also add this to the SSZ breakout?

[etan-status]

Vitalik's post and EIP-6404 should be enough for the SSZ breakout. The primary discussion point to address is about the ossification of common transaction fields vs the unrestricted Union/Onion. For all other SSZ aspects, the current infrastructure (Ethereum Magicians threads and Discord) should be sufficient.

Have split EIP-6466 (Receipts) and EIP-6465 (Withdrawals) from EIP-6404, and will update them according to the SSZ breakout discussion as well.

For the next ACDE (this GH issue), EIP-6465 should be discussed for inclusion in Cancun. Execution clients will require SSZ support for EIP-4844 anyway, so Cancun seems to be a good target to get withdrawals migrated.

I'd like a few minutes to discuss and get feedback on this PR to standardize the txpool API
ethereum/execution-apis#353

[tersec]

Would like to discuss the upcoming status of the minimal preset on the execution layer, since https://github.com/ethereum/execution-apis/blob/main/src/engine/experimental/blob-extension.md#blobsbundlev1 means that now the EL needs to care in some way via the engine API.
