ZK proofs are only required for communication between rollups or exit of funds back to L1. Otherwise confirmations times are fast (as fast as L1)—the L2 node simply needs to execute the transactions included in the DAG in order (similarly to a krc-20 indexer following the DAG for…

**Understanding the Importance of ZK Proofs in Rollup Communication: Insights from Michael Sutton**
Michael Sutton, a prominent Distributed Systems Researcher and Developer, and one of the core developers of the innovative Kaspa blockchain, recently shared his insights on the necessity of Zero-Knowledge (ZK) proofs in communication between rollups and fund exits to Layer 1 (L1) blockchains. His tweet, dated December 10, 2024, brought attention to the operational efficiencies of Layer 2 (L2) transactions and the role they play in enhancing confirmation speeds.
Sutton explained that ZK proofs are only essential in specific scenarios: when rollups communicate with each other or when funds are being pulled back to L1. In all other cases, he emphasized, the confirmation times can be as rapid as those of L1. The L2 node processes transactions by executing them in a Directed Acyclic Graph (DAG) order, similar to how a token indexer operates within the Kaspa network. This method allows L2 solutions to maintain high-speed performance without compromising security and efficiency, demonstrating Kaspa’s capability in handling complex transaction environments.
This insight underscores the technical sophistication of Kaspa, particularly in the realm of decentralized finance (DeFi) and scalability solutions. By prioritizing swift transaction confirmations and minimizing the dependency on ZK proofs, Kaspa positions itself as a formidable player in the evolving landscape of blockchain technology.
