If time permits, I'd love to chat about the current status of (block, slot) fork choice analysis for ePBS. As analysis done in these documents:

Besides the current post-anti and ex-anti analysis of two slots sandwich attacks, what other analysis/attack is worth studying over. One example is multi-slot liveness attack. As the performance of network conditions becomes worse, chain growth stops completely if block latency is > 3 seconds. Whether a backoff scheme is necessary to facilitate chain progression during periods of extended latency

If there's time (writing here mostly for the next breakout) I'd like to brainstorm how an "off-protocol" solution actually would play out. It seems to me that ePBS makes any out of protocol solution very very hard to be viable.

I wrote a post today on out-of-protocol timelines under ePBS: https://hackmd.io/@ttsao/comp_epbs_timelines. It's the worst of both worlds.
