Friend Recommendation and Content Sharing in Decentralized Online Social Networks


Current Online Social Networks (OSNs) are platforms managed in a central manner and impose many restrictions for their users: they lose control over their data and cannot individualize their platforms. Although decentralized alternatives exist, they have a lack of ease of use and important features such as friend recommendations. Therefore, in this project you will set up a decentralized OSN using existing technologies to send messages, share status updates etc. and beyond, design and implement sophisticated algorithms to enable two crucial features: friend recommendations and content sharing. People using this solutions shall be able to easily set up their own social profile and experience the cool features OSNs offer nowadays.


  • Research existing solutions of decentralized social networks and decentralized micro blogging software
  • Use the most promising technologies you researched about to set up a Decentralized OSN (DOSN) providing basic functionalities
  • Extend the DOSN by a friend recommendation function and the ability of content sharing


  • Experiences with Social Networks, Blogging / CMS, Recommender Systems
  • Sound knowledge of web protocols to enable content sharing
  • Creativity and understanding of algorithms to develop a friend recommendation system
