GNU Taler: beyond digital money (WHY2025)

What this episode covers

In this talk you will learn how [GNU Taler](https://taler.net/), a privacy-focused payment system, leverages the properties of digital tokens and blind signatures to enable a wide array of use cases such as discount coupons, subscriptions, and tax-deductible donation receipts; all while preserving untraceability in customer-to-merchant transactions.
