Workshop on Rollup Sequencer Economics: Small Group Discussion

Ben Fisch

A small group discussion with participation from members of the a16z crypto summer research lab focused on open questions around rollups – horizontally scaling the application layer of Ethereum. This group focused on the question: How is revenue shared among rollups utilizing the same sequencing layer? They briefly touch on elicitation and then focus on the revenue sharing.

All of the groups (including those that focused on how a shared sequencing layer could simultaneously support multiple approaches favored by each individual rollup; and how a shared sequencing layer should think about fees) report out at the end of the session.

About the organizer

Ben is co-founder and CEO of Espresso Systems, which is building a decentralized sequencing and data-availability layer for Ethereum rollups and app-chains. Espresso Systems has partnered with Eigenlayer to deploy this “Layer 1.5” to the Ethereum physical validator set itself, to minimize additional security assumptions and offer Layer 1 validators exposure to value being created at Layer 2. Ben is also an assistant professor of computer science at Yale University. He completed his PhD at Stanford University under the supervision of Dan Boneh. His graduate research on proof systems, including proofs-of-replication and verifiable-delay-functions, contributed to the development of several prominent blockchains including Filecoin, Chia, and Ethereum’s beacon chain.
