Wrote a post on FOCIL resource considerations after reflecting on how clients might implement it. We outlined some concerns about potential bottlenecks, hoping to spark more discussions to move it toward the spec realization phase. Feedback welcome! https://ethresear.ch/t/focil-resource-design-considerations/20457

ePBS breakout #8 notes: https://hackmd.io/@ttsao/epbs-breakout-8 Moving to slot auctions seems imminent at this point, the question is when. If we want to have slot auctions for the very first client devnet, then the sooner the better

Without more than a high-level Ethereum research post or a 35-minute video, it's hard to judge how simple or difficult BRAID is. I'm typically in the "devil is in the details" camp. One thing BRAID simplifies over something like FOCIL is that it doesn't require introducing a third type of actor (inclusion list constructor). Without this additional actor and duty, your slot anatomy flows just the same as today, avoiding conflicts over how to split the 12-second slot time, which I discussed more here: https://ethresear.ch/t/inclusion-list-timing-constraints/20198 BRAID's complexity will revolve around fork choice, consensus changes, and dealing with DOS and free DA. It takes a more from-scratch approach, which is often cleaner but will require more research and engineering cycles to fully understand its full implications.

Hi Davide, ePBS (EIP-7732: block auction) opens the door for APS. It's the first attempt to organize market structure into the protocol. If this is successful, we can look into extending it to slot auction, future slot auction, ET/EA. We have to start somewhere : ) I'm interested to hear feedback on whether ePBS is not forward compatible with APS from you and the RIG team!

New post on inclusion list timing constraints: Different designs bring different timing limitations for inclusion list actors. We argue there's no perfect design due to trade-offs within an Ethereum slot. Feedback welcome. https://ethresear.ch/t/inclusion-list-timing-constraints/20198

New post on builder bidding behaviors in ePBS, inspired by "Strategic Bidding Wars in On-chain Auctions". In the post we explore market changes from MEV-Boost to bid p2p and builder RPC, and discover a new single bluff strategy on p2p. Special thanks to @soispoke for the review! 🔗 https://ethresear.ch/t/builder-bidding-behaviors-in-epbs/20129 🔗 https://arxiv.org/abs/2312.14510

That's the property of this inclusion list mechanism (forward-based): for a block to be accepted, it must also include one inclusion list to be enforced for the next slot proposer.

Here are my slides for ethcc on redefining trust between proposer and builder through ePBS. Today, to use a builder, a proposer MUST trust a relayer, which carries invisible costs across multiple domains: money, latency, fault, schedule, and healthy market dynamics. I argue that these costs become cheaper (or go away) with ePBS. Enjoy! https://docs.google.com/presentation/d/1Jw0EZvkZzzeKWi-yehwLWdIl4VEZ1Le9_ywDrFDS6Oc/edit?usp=sharing

Here are the slides during ethcc on pipelining ethereum consensus & execution. While many discuss pbs for trust, censorship, and latency, few highlight its benefits for better slot utilization, more execution time & DA time. https://docs.google.com/presentation/d/1Il19qu0b7gr7GBUCNkr-aRh8lqxmBX5OSqfv5mVtTAA/edit?usp=sharing
