 This repository contains a collection of Android apps built on top of [IPv8](https://github.com/MattSkala/kotlin-ipv8) (our P2P networking stack) and [TrustChain](https://github.com/Tribler/kotlin-ipv8/blob/master/doc/TrustChainCommunity.md) (a scalable, distributed, pair-wise ledger). All applications are built into a single APK, following the concept of [super apps](https://home.kpmg/xx/en/home/insights/2019/06/super-app-or-super-disruption.html) – an emerging trend that allows to provide an ecosystem for multiple services within a single all-in-one app experience.
