Rusty Russell rejoins me on the show to talk about a new idea for a bitcoin soft fork that hopefully avoids some of the ‘horse trading’ dynamic that existed amongst other proposals. Listen in to learn more about the different paradigm that Rusty introduces here, so that developers can build more functionality and efficiency in, hopefully so that more people can use Bitcoin in self-custody.
