Librefin: Building a FOSS UPI App

Approved
Session Description

2 years ago, we announced the LibreFin project at IndiaFOSS to chart a way forward to a FOSS UPI app. This time, we have updates and a demo.

The talk will cover:

  1. A quick demo of a FOSS UPI Payment†

  2. Recent developments in UPI and how they relate to our work (UPI Lite, UPI Lite X, UPI Circle)

  3. Copyright Law and Reverse Engineering and legality of building an interoperable FOSS solution.

  4. Technical details about the reverse engineering work involved in building this.

  5. A community call for contributing to the project.

† - Our demo is still a work in progress, but should be ready by IndiaFOSS.

Key Takeaways

  • Why do we need a FOSS UPI app?

  • What does it take to build an interoperable FOSS app?

  • Copyright law and interoperability exemptions in India

  • A little about the technical architecture behind UPI.

Sounds like a very hot button issue in the Indian FOSS world. Be sure to point out the non FOSS nature of the current setup and how new merchant are/were gate-kept. If handled well it could be on of the best talks.

This is a very cool topic and a lot of people including myself would look forward to know the underlying details of UPI and how an open client can be made. I would love to see this become real, because I really dont like the idea of other apps snooping into their users' buying histories or patterns.
