Episode notes

Rolps will have this market of it's billions of dollars of M.E.V extracted from Ethereum in the next few years, says Josh Goldfarb. Roll ups are not giving up something just the point of using shared sequence there is not that the sequence or is providing them with decentralization that they would be able to do," he said. "There's also an ideological perspective here right like not going like to in the weeds here right but like you know arbitrum very obviously has like an opinionated take on like M.e.V. and what they believe to be a more correct or fair distribution"

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.
