In this episode, Bitcoin Developer Sergio Lerner joins the show to discuss Bitcoin’s latest development battles–from the OP_RETURN data wars to the future of programmable Bitcoin through BitVMX. He argues that filtering Bitcoin transactions restricts innovation, outlines the real-world financial use cases enabled by protocols like RSK, and explains how new Bitcoin Layer 2s can enhance scalability and security without altering Bitcoin’s base layer. We also touch on Bitcoin’s long-term viability, mining centralization, and the cultural rift with broader crypto. Enjoy!
