Technology Stack of the I2P-based, Free and Fully Distributed Banking Technology DIVA: Presentation at FOSSASIA 2021

The presentation at FOSSASIA, held in March 2021, is about the technology stack of the I2P based, fully distributed banking and exchange technology DIVA. DIVA is a software package licenced under AGPLv3, produced by the not-for-profit association DIVA.EXCHANGE. Konrad, the lead architect, shows how to install DIVA, how to run DIVA on your local device and hence how to become your own local I2P based, fully distributed bank and exchange. How to become part of this open source and free technology project rounds off the lecture. This article provides an overview of each section of the lecture and access to the recording of the lecture.
