Upgrading the MEV Supply Chain w/ Drew Van Der Werff (Com...

What this episode covers

Rex sits down with Drew Van Der Werff, founder of Commit-Boost and Fabric, to talk about the future of Ethereum block production: from validator autonomy and pre-confirmations to full-slot auctions, inclusion lists, and what a more robust PBS pipeline might look like. They dig into how Commit-Boost turns the validator stack into an “app store” for block construction, why derivatives on blockspace could actually stabilize Ethereum, and where TEEs fit (or don’t) alongside ZK. The conversation zooms out to the state of the Ethereum social layer, the role of the EF and client teams, and why Drew splits his time between cutting-edge protocol work and running a very real-world American machine shop.Referenced Links:Previous conversation with Drew Van Der WerffOpportunities and Considerations of Ethereum’s Blockspace FutureGrounded Relay: Superpowers from Relay Coordination

The issues being decided in the halls of government every day have real and lasting impact on all our lives, but discussing politics is extremely unpleasant. It is very difficult today to have a calm, adult conversation about politics. Are the people screaming on TV, the radio, and online really who “we” are? Are they really representative of mainstream America or are they just really aggressive and loud? I believe the adults just got tired of it and walked away, but their silence is not consent. This podcast is the test of that theory. If you see fit to tune in, I will present news of the day, analysis and commentary while doing my best to check my feelings at the door and let you, the listeners, decide what it means to you. No ominous music, no angry rants, just a relaxed conversation and positive vibe. Politics, for reasonable people.
