Modular March EP 15: Where Espresso Fits In The Modular Thesis

We really enjoyed this presentation. While we’ve had multiple shared sequencers talks on Modular March, each one has been far different. Today’s deep dive is around the game theory and incentive designs behind creating a rollup ecosystem which feels completely seamless and interoperable. At its core, Espresso leverages a two part system to enforce how transactions are ordered and finalized across rollups via its sequencer. This system mirrors Ethereum's, but with a twist, aiming to streamline interactions between different rollups and thereby improve user experience significantly. We discussed the based sequencing approach, their auction & lottery mechanism, and where Espresso fits in the broader modular thesis. While we are bullish on Espresso (and Ellie is amazing), we didn’t let their vision go untouched so to speak. There were areas where we pushed back around the incentive designs and whether or not this would actually work in practice. We also tried to understand why potentially making things more complex is really the solution for scaling the modular L2 landscape. Also, if Espresso is another chain with trust assumptions, what tradeoffs does that bring for rollup operators? Finally the big question…Will rollup operators really want to use Espresso if it could cause a big revenue reduction? Ellie flipped that narrative on its head, ever so graciously. She helped us understand how Espresso works under the hood and answered our questions. We were impressed and left feeling extremely optimistic on shared sequencing. Happy April Fools Day (no jokes here, yet!) & let’s have a great week!

Modular March EP 13: Where Across Fits In The Modular Thesis

Again, we find ourselves returning to the interoperability and fragmentation problem of the modular expansion. We’ll keep it real, there is nothing innovative of building hundreds of siloed execution environments. Even if you value sovereignty as much as the rest of us, having reachable allies in the onchain world is a necessity. As new L2s and appchains are launched (which is happening at an alarmingly high rate), the ability to seamlessly interact across chains becomes crucial for the broader adoption and user experience. In today’s video, we set out to learn if an intent-based design is a viable solution. We had the pleasure of sitting down with Hart, co-founder of UMA & Across, to discuss why he believes intents are the future of interoperability. This design employs third-party actors, known as relayers or solvers, who provide the liquidity needed for cross-chain transactions, thereby allowing sub one second transfers and enhanced security (no ‘honeypots’ for hackers). But, as always, we pushed back. Is there really a way to scale an intents based design to 1000s of chains? Is value transfer the only necessity of bridging in crypto or is there also a demand for messaging? Why are solvers sometimes slow to fill orders vs. extremely quick in other scenarios? We really vibe with Hart well, and he wasn’t fearful of any questioning on his mental models. We enjoyed hearing his perspectives and learning from him. You probably will, too.
