Trustchain - creating trust play online

Kotlin implementation of Trustchain and IPv8 with rich networking: multihoming of local Bluetooth+4G, decentral social networking, UDP hole punching, etc.

A collection of mini apps built on top of IPv8 (a P2P networking stack) and TrustChain (a scalable, distributed, pair-wise ledger). All applications are built into a single APK, following the concept of super apps an emerging trend that allows to provide an ecosystem for multiple services within a single all-in-one app experience.

PeerChat
PeerChat implements a fully functional prototype of a distributed messaging app. First, the users have to exchange the public keys by scanning each other's QR code, or by copy-pasting the hexadecimal public keys. This guarantees authenticity of all messages which are signed by their author. It prevents man-in-the-middle and impersonation attacks.

Luxury Communism
Luxury communism is an Android application built on top of IPv8 and Trustchain, and is integrated into the Trustchain Superapp. It is a proof-of-concept implementation of a DAO system using Trustchain and Bitcoin. Trustchain is used for communication and bookkeeping while the Bitcoin blockchain is used to have collective multi-signature wallets for each DAO. The content of the app is split up in several tabs:

MusicDAO
In short, the MusicDAO is an IPv8 app where users can share and discover tracks on the trustchain. Track streaming, downloading, and seeking interactions are done using JLibtorrent.

TrustChain Explorer
TrustChain Explorer allows to browse the TrustChain blocks stored locally on the device and crawl chains of other connected peers.
