[SamWilsn]

I'd like to discuss adopting the execution-specs as part of the EIP process.

@timbeiko has sketched up what that might look like, and I'm interested to hear core dev's thoughts.

I'd like to give a quick update on the Flashbots mev-boost relay.

I'd like to announce:

• Engine API RFC
  • [RFC] Engine API: remove INVALID_BLOCK_HASH execution-apis#270
  • [RFC] Engine API: is payload statuses worth reworking? execution-apis#271
• Checkpoint Sync API
  • Checkpoint Sync API beacon-APIs#226

[mkalinin]

I would like to also discuss the following situation:

1. BlockA and BlockB are competing terminal blocks where BlockA.TD >= BlockB.TD
2. A portion of nodes receives BlockA first and do not propagate BlockB because it hasn't fully imported BlockB
3. Nodes that haven't received BlockB because of (2) get stuck at the merge transition block atop of BlockB due to SAFE_SLOTS_TO_IMPORT_OPTIMISTICALLY timeout

My understanding is that (2) won't happen because all EL clients propagate all gossiped blocks after verifying PoW seal. I would like to double check this understanding with client teams.

Closed in favor of #592
