S15 E13: Robin Linus on BitVM & Permissionless Bitcoin Development

Robin Linus talks about BitVM, trust minimized sidechains, and everything else which enables permissionless development in Bitcoin. Thanks to BitVM, in the next couple of years we'll see many more scaling solutions such as sovereign rollups.
