F-Droid Architecture for Reproducible Apps

F-Droid has been bringing reproducible builds to the Free Software Android ecosystem since 2015. We have complete build automation for managing source from upstream, building them and publishing them via a secure pipeline. We have automatic rebuilders that confirm that apps have been reproducibly and point out the differences when not. We include best practices for trustworthy software: open source, transparent reviews, reproducible builds, user-chosen curation, etc. In this project, we will research how users evaluate trustworthiness, and use this to fix pain points and develop better strategies for communicating our key benefits. We will also improve F-Droid's automation to ship more reproducibly built, reviewed apps at a faster pace. We'll expand reproducible builds as a practice by improving integration and easing deployment. This makes it easier for people to not only understand and appreciate the importance of these essential practices, but to adopt them in practice.
