For full decentralization and security, the limit will be the L1 TPS, but L1 will not need to execute L2 transactions, only to provide data availability for them. For use-cases which do not require such strong guarantees, L2 entities will be able to provide more TPS

**Michael Sutton Discusses Layer 1 and Layer 2 Scalability in Blockchain Systems**
In a recent tweet, Michael Sutton, a prominent Distributed Systems Researcher and Developer, as well as one of the core developers of Kaspa, addressed a critical aspect of blockchain technology concerning scalability and security. Sutton’s commentary highlights the ongoing evolution of blockchain architecture, specifically the interaction between Layer 1 (L1) and Layer 2 (L2) solutions.
“For full decentralization and security,” Sutton stated, “the limit will be the L1 TPS, but L1 will not need to execute L2 transactions, only to provide data availability for them.” Essentially, he is referring to the inherent transaction per second (TPS) limitations of Layer 1 solutions, which operate under stricter security and decentralization protocols. In contrast, Layer 2 solutions have the flexibility to offer significantly higher transaction speeds, as they do not carry the same necessity for robust security and decentralization measures.
This insight is particularly relevant to the Kaspa blockchain, which is designed to push the boundaries of speed and scalability while maintaining security. Kaspa utilizes a unique approach to block production and finality, allowing it to handle a large volume of transactions effectively. By leveraging both L1 and L2 solutions, Kaspa aims to provide a balanced approach to scalability, enabling quicker transactions for use cases that do not necessitate the higher guarantees associated with Layer 1.
Sutton’s observations resonate with the broader conversation in the blockchain community about optimizing performance and user experience. As applications on blockchain networks continue to grow in complexity and volume, the need for efficient transaction processing without compromising security becomes ever more vital.
