I’ve been looking at what it would take to build TEEs with much better security assumptions (and much greater success at being secure within those assumptions) This podcast gives a great overview of why one would even want to do this and how Accompanying blogpost: https://writings.flashbots.net/ZTEE2-Supply-Chains

Just published a piece with Christoph which frames all of the research going into “propsing rights allocation” (i.e. ePBS, APS, ET etc) There are a bunch of designs, posts and papers but its not always clear how it all relates to each other. We try to clarify that Some opinions and open questions also included https://collective.flashbots.net/t/isolating-attesters-from-mev/3837?u=quintus

The recent bok victories are so much more satisfying when you take into account the new players and strategies we’re trialing

Nice new post from Christoph Schlegel at Flashbots tl;dr: APS designs with an inelastic supply of "proposing rights" lead to more market concentration than elastic supply I.e. having a fixed number of exec tickets likely leads-to-winner-takes-all unlike systems that resemble PoS in which people can stake as much as they like This is one of a number of recent pieces that have been narrowing down the design space for Ethereum’s proposing rights allocation (APS, ePBS etc) https://collective.flashbots.net/t/inelastic-vs-elastic-supply-why-proof-of-stake-could-be-less-centralizing-than-execution-tickets/3816?u=quintus

In case anyone's missed it, here's intel's response to the recent claimed vuln tl;dr: Seems theres a bunch of reasons not to worry about this specific "vuln" Ofc the broader point that TEE-based systems should be designed in anticipation of failures is still valid https://www.intel.com/content/www/us/en/security-center/announcement/intel-security-announcement-2024-08-29-001.html

Great article to learn how TEEs (don’t) really work and some fixes https://collective.flashbots.net/t/closing-the-intel-tdx-page-fault-side-channel-or-the-case-for-tdexit-notify/3775

Can’t tell if “wallet” is a terrible name for the software users use to control their keys because its so much more than moving and custodying funds Or if its a great name because it frames more of our identity snd the information we put out into the world as valuable

If your boss offered you a promotion in exchange for sexual favours would that be bad practice because he has your career branching on secret bits? (This is a joke to clear)

What are the important differences between execution tickets and have a new class of stakers who get paid only for proposing blocks? Both see people depositing capital and then random selection weighted by deposit Is the primary diff is that tickets are tradeable?

Been thinking about things in this direction with execution ticket conversations heating up https://m.youtube.com/watch?si=ECRd8DCMOC9Ewzn5&v=XYg_0rt9pv8&feature=youtu.be
