Fabian Jahr and Gloria Zhao rejoin me to discuss whether big projects can be done inside Bitcoin core. We delve into AssumeUTXO, ASMap, developer funding, and meritocracy in the developer community.

Summary

In this episode, Stephan discusses the upcoming Bitcoin Core version 28, its new features, and the ongoing development efforts with Fabian and Gloria. They delve into the pace of change within Bitcoin Core, the importance of communication and collaboration in software development, and the challenges faced by developers in getting projects approved. The conversation also covers the AssumeUTXO project, its implications for node operation, and the significance of funding and competing implementations in the Bitcoin ecosystem. The episode concludes with insights into future projects and the collaborative nature of Bitcoin development.
