1. Right.
2. NO. It only needs to save the state as of the last proven point (i.e., that which is encoded in the last SCU). To be more safe regarding reorgs it might need to save the state at the time of L1’s recent pruning point, but not before.

**Understanding Michael Sutton’s Insights on State Management in Distributed Systems**
In a recent Twitter exchange, Michael Sutton, a prominent Distributed Systems Researcher and Developer, and one of the core developers of the groundbreaking blockchain project Kaspa, shared key insights into state management within Layer 2 (L2) solutions. His comments specifically addressed the need for L2 systems to handle state savings effectively to enhance security and efficiency.
Sutton clarified that an L2 system only needs to save its state based on the last proven point—essentially, the information encoded in the most recent State Commitment Update (SCU). This approach significantly simplifies the state-saving process, as it allows for reliance on proven data points that ensure the integrity and continuity of the system.
Moreover, he highlighted that while storing the state as of the last SCU is generally sufficient, there may be added safety in saving the state at the time of Layer 1 (L1) pruning points. This consideration becomes crucial in scenarios involving reorganization (reorgs) in the blockchain, which can impact the reliability of the data if not handled properly.
Sutton’s remarks underscore the importance of efficient state management in the context of distributed ledger technologies like Kaspa, where speed and scalability are critical. As one of the pioneers working on the Kaspa project, Sutton’s insights reflect the ongoing efforts to refine Layer 2 solutions, thereby enhancing user experience and system robustness.
