In this conversation with Stephan, David and Simanta discuss the implications of ZK Roll-ups for Bitcoin. They explore the benefits of ZK Roll-ups as a scaling solution, the trade-offs compared to other technologies like Lightning Network and sidechains, and the vision behind Alpen Labs. 

The discussion also touches on the mechanics of ZK Roll-ups, user experience, and the potential impact of BitVM on the ecosystem. The conversation highlights the challenges and limitations of current technology while emphasizing the future possibilities for Bitcoin's programmability and user interaction. 

David & Simanta also address the risks associated with ZK Rollups, particularly in terms of data availability and trust assumptions, while exploring the future of Bitcoin and the implications of increased data usage on the network.
