Builders & Relays in ePBS @_eltitan highlighted two main changes from @titanbuilderxyz persp: 1. Auction mechanism will adapt from open second price to blind first price 2. Need for staked collateral increases barrier to entry for new builders details:

the Free Option Problem remains one of most important issues for ePBS and is extensively discussed by @mikeneuder @hasufl @Data_Always @terencechain @potuz_eth @barnabemonnot & others e.g. in these threads: https://t.co/hb1QTWoGKp

IMH(umble)O, the free-option problem should be seen as a P0 bug in our thinking about ePBS! 🪲🛑 without getting bogged down in the greeks, the intuition is simple: builders *will be* incentivized to intentionally miss slots – especially during periods of high volatility.

Free Option Problem: if with ePBS the builder has the "free option" to cancel the exec payload just before PTC deadline, how often will that lead to empty blocks? details here by Flashbots: https://t.co/DSyGRNN3fS prev brought up by @_julianma & RIG: https://t.co/S0kaARO7fs

As you can see, different EIPs have second order effects on preconfirmations and create a very dynamic environment for teams and adoption. For a detailed breakdown of how different EIPs impact preconfirmation compatibility, read the full research here:

In proposals like MCP, inclusion preconfirmations remain compatible. However, execution preconfirmations break if no proposer can enforce priority over the final block content

However, APS introduces specialized execution proposers via auctions or lotteries. Inclusion preconfirmations are compatible only if the proposer is elected before the slot begins and either doesn’t resell or can enforce commitments when resold. Is this realistic?

For example, FOCIL is fully compatible with both inclusion and execution preconfirmations. It doesn't require any changes to existing protocols, making it a smooth fit in the evolving Ethereum landscape and one less thing for preconf teams to worry about

The research explored a range of different EIPs and found that some are compatible with existing preconfirmation protocols, but others require adjustments and coordination across parties to ensure they continue to work as Ethereum evolves
