The talk explores the challenges of the L2s communicating with L1, including the finalization limitations, security risks, and attack vectors. We focus on spaceTEE and how it can enhance the pre-confirmations and security for its users and L2s.
This talk will explore the challenges of L2s communicating with L1, including finalization limitations, security risks, and attack vectors. A key focus will be on how robust L1 (Spacecoin) can support L2s, improving both efficiency and security for its users. Additionally, the role of TEEs (especially SpaceTEE) in enhancing pre-confirmations and securing cross-layer interactions will be discussed, highlighting their potential to address critical scalability and trust issues.
As a part of the interaction of L2s with L1, they can communicate with the robust infrastructure of spaceTEEs that can provide an attestation that a certain data transition is valid.
Filip Rezabek received the Master of Science degree in communications engineering from the Technical University of Munich, in 2020. He is currently pursuing the Ph.D. degree with the Chair of Network Architectures and Services. His research interests include network security, applied and threshold cryptography, and distributed systems resilience and robustness. Besides, he is active in the area of TSN with focus on intra-vehicular networks and smart manufacturing. For both areas are important aspects of reproducible experiments
