Join us on our nineteenth Bitcoin Socratic Seminar! A special thank you to our sponsor, Btrust for food and refreshments.
MC: Michael Ariwaodo
Michael opened with a talk on Cashu, a Chaumian ecash protocol built on Bitcoin and Lightning, with a clean spec and growing reference implementations.
He covered the core problem Cashu solves, its history, minting and melting, and how to get involved in the community. On the cryptography, he explained the Blind Diffie-Hellman Key Exchange that makes mint-side unlinkability possible, how the NUT specifications turn that into a concrete mint and wallet API, and why a string of characters can be money. He wrapped up with a demo of a Cashu wallet, mints and their configurations.
MC: Nonso Amadi
Nonso walked us through Lnaudit, a project he is building to give security reporting on possible vulnerabilities in Lightning setups. It learns from the postmortems of some of the biggest hacks in Bitcoin so that future nodes are better secured, and it uses AI and other tools to keep learning from new vulnerabilities and keep pace with changes in the security world.
The session covered the lesson from historical evidence, the security visibility gap in Lightning tooling, what Lnaudit does and the actions it recommends, why it is written in Go, what it is not, how to use it, and the roadmap.
