@xImHoveR Both L1 and L2. L1 needs to be adjusted and expanded to support the needs of L2s. This L1 expansion is also typically referred to as “ZK opcodes”, but it includes more than that.
### Michael Sutton Discusses the Future of Layer 1 and Layer 2 in Blockchain Technology

In a recent discussion on Twitter, Michael Sutton, a distinguished Distributed Systems Researcher and Developer, and one of the core developers of the innovative Kaspa blockchain, shed light on the evolving dynamics between Layer 1 (L1) and Layer 2 (L2) solutions in the world of blockchain technology. His insights emphasized the necessity for L1 to adapt and expand in order to adequately support the diverse needs of L2s.

Sutton highlighted that while L1 is often characterized by its foundational protocols and security layers, it requires significant adjustments to maximize its functionality. This expansion is crucial for the growing ecosystem of Layer 2 solutions, which aim to improve scalability and reduce transaction costs.

He further elaborated that this L1 enhancement is often associated with “ZK opcodes,” a term that refers to zero-knowledge proofs designed for increased efficiency and privacy. However, Sutton pointed out that the scope of this expansion goes beyond just ZK opcodes, encompassing a broader range of technological advancements and optimizations that will enable the seamless interaction between L1 and L2 solutions.

His comments come at a pivotal time as the blockchain community increasingly explores ways to enhance interaction and interoperability between various layers. As the Kaspa project—an initiative characterized by its unique consensus algorithm and high transaction throughput—continues to develop, Sutton’s perspective underscores the importance of creating a robust L1 infrastructure that can support the functionalities expected from advanced L2 solutions.
