Digital Cash: What It Is & How It Works • Lars Hupel • GOTO 2023

This presentation was recorded at GOTO Amsterdam 2023. #GOTOcon #GOTOams https://gotoams.nl Lars Hupel - Chief Evangelist at Giesecke+Devrient @larsr_h RESOURCES https://mastodon.hupel.info/@lars https://linkedin.com/in/lars-hupel https://lars.hupel.info ABSTRACT When we think of "electronic payments", there are a lot of different interpretations: bank cards, credit cards, PayPal and the likes, mobile money, and cryptocurrencies. But they all work in widely different ways. Lately, many central banks – including the European Central Bank – have started investigating or piloting digital currencies to introduce yet another way to pay electronically. In this talk, I will explain the technical (and social) differences between those payment methods and give insights into how such a digital currency platform could be designed.
