I've been chatting w/ the flashbots folks about mitigations to prevent liveness failures around the external builder network post-merge and we are narrowing in on a suggestion to implement a "circuit breaker" in the event that a relay fails to release blocks they are responsible for.

I'd like a few minutes to discuss the solution and get feedback from CL teams as this is best implemented as a policy in the beacon node software.

edit: here is a WIP proposal for what a MVP of this could look like: https://hackmd.io/@ralexstokes/BJn9N6Thc

I'll walk through this on the spec call and posting here in case anyone wants to review ahead of time

I would like to briefly go over expected EL's behaviour around multiple terminal blocks received via PoW gossip

I would also like to confirm CLs agree with this PR: ethereum/builder-specs#38

which disables use of the builder network through the merge transition.

It reflects our discussion from the last call and I would like a final ACK before merging.

If there is time I would like to gather opinions of others about this PR: ethereum/builder-specs#41 which aims to standardize a proposer config file format and make it reusable across CL clients and mev-boost. A lot of the discussion happened already in this PR: flashbots/mev-boost#154

If there is a time I would like to discuss this PR ethereum/consensus-specs#2955 and general behaviour of a node if it ends up with the fork choice state which doesn't have viable branches in a block tree

I would like to raise the current incompatibility between LH and Geth with TransitionConfigurationV1 before the TTD has been announced.

I don't really mind what happens here, I would just like to see a standard so that users can start making their nodes merge-ready as soon as possible.
