Episode notes

Espresso and Astrid are building a shared sequencer network. The idea is to get all these different roll ups to regain interoperability, not only share security but also decentralization. Ben: Roll up design is more flexible and how you can do the sharding. It doesn't kind of box you into like one kind of sharding mechanism as a whole.

Join us on 0xResearch as Josh Bown (Astria) and Ben Fisch (Espresso Systems) join us to discuss the role of shared sequencers in the modular future. Josh and Ben explain how shared sequencers remove the risk of censorship, liveness and regulation for rollups while creating a layer for atomic composability. Will L2s choose to leverage a shared sequencer? What is the value proposition? Where will value and MEV capture occur? We discuss all of this and more!

And as usual, we start the episode with our analyst bullpen to discuss Voltz v2 cross-margining, Crypto's mobile-first UX improvement and an update on Arbitrum.
