Episode notes

Calle gets into into the future of financial and communication privacy, exploring how tools like Cashu and BitChat could help Bitcoiners survive in an increasingly hostile regulatory environment.


He breaks down why privacy is essential for democracy, the lessons from the original Crypto Wars, and how eCash can offer near-perfect transaction privacy.


Calle explains the history behind David Chaum’s invention, the trade-offs Bitcoin made for auditability, and why eCash mints could be run by communities for both Lightning payments and private internet services. As well as BitChat as a censorship-resistant messenger and the growing legal risks faced by privacy developers.


In this episode:


- Why financial privacy is as important as free speech


- Lessons from the Crypto Wars 1.0


- How Chaumian eCash works and why it’s unmatched for privacy


- Offline payments and tap-to-pay Bitcoin


- The risks and pressures facing privacy developers today
