This article introduces the first installment of a 10-episode video series dedicated to the crucial topic of Bitcoin privacy, which was filmed at the bitcoin++ Privacy Edition in Riga and other locations. Each episode in the series aims to delve into various aspects of Bitcoin privacy, including practical tools for private Bitcoin usage and an examination of surveillance techniques employed in the digital realm. A core tenet explored is the symbiotic relationship between privacy and censorship resistance, positing them as two inseparable sides of the same coin. The series emphasizes that when interactions cannot be conducted privately, they become public knowledge, rendering participants vulnerable to external pressures such as shunning, shaming, jailing, or other forms of penalization. Consequently, without privacy, the very foundation of censorship resistance is undermined, leading most individuals to inevitably censor themselves.

The second episode of this insightful series features a discussion with Calle, the visionary creator behind the Cashu ecash protocol. This conversation focuses on the pervasive erosion of privacy in the modern internet landscape. In an era dominated by large, seemingly free internet platforms, the true cost of access is often paid through the sacrifice of personal privacy, primarily to fuel advertising revenue models. This prevalent economic structure of the internet represents a significant departure from its foundational vision, where users were expected to pay for access to resources—a concept evident in the original HTTP protocol's inclusion of the '402 Payment Required' error message from its inception. The dialogue with Calle explores how Cashu, by facilitating Bitcoin micropayments, presents a promising opportunity to reverse this trend. It offers a pathway to rebuild a privacy-respecting internet, aligning with the initial designs and aspirations for the world wide web.
