The Helios@AI4EU Cafe has presented the Speaker Barbara Guidi (Assistant Professor at the Department of Computer Science of the University of Pisa)
This Café session is a cross-project collaboration between the Horizon 2020 European Research Projects HELIOS and AI4EU in the current Next Generation Internet Program.
Description: Online Social Networks (OSNs) have changed the way of how people interact, however lately people are questioning more and more their business models. During the last ten years, new solutions based on decentralised architectures have been proposed, namely, Decentralized Online Social Networks (DOSNs) and Blockchain Online Social Medias (BOSMs). DOSNs were introduced several years ago and their main goal is the preservation of the privacy of the users in such a way that the data and the content of a user are always under their control. BOSMs leverage the usage of blockchain either to enforce the privacy of the users or to redistribute the wealth generated by the platform through a rewarding system. Steemit is the most stable and well-known BOSM with more than 1 million registered users, where users can create their own Social Network by following other users. This talk presents the characteristics of decentralization and what DOSNs and BOSMs are by presenting existing platforms.
