Limitations of Lightning for Mass Self-Custody

In this episode, Kevin Hurley, CTO and co-founder of Lightspark, discusses the Layer 2 solution called Spark, which aims to enhance Bitcoin's scalability and user experience. He shares insights from his journey transitioning from the Libra project to building on Bitcoin, addressing challenges faced with the Lightning Network, and the unique features of Spark, including its architecture, user experience, and future developments. The conversation also touches on trust, privacy, tokenization, and the importance of community engagement in the Spark ecosystem.

Takeaways:

🔸Spark aims to provide a scalable and user-friendly Layer 2 solution for Bitcoin.
