L2 Interoperability via Collaborative SNARKs by Ben Fisch | Devcon SEA

Sat, Feb 15, 2025, 02:53 PM · 25:26

Can contracts across rollups interact synchronously while maintaining horizontal scalability? The L2 interoperability problem can be viewed through the lens of collaborative SNARKs, where a coordinator splits a witness over N provers who collectively generate a proof, and the work each prover does should decrease linearly in N (horizonal scaling). This talk presents a solution for the special case of L2 interoperability and motivates new design constraints for SNARKs.
