-Although this implementation model has proven to be highly functional and has improved significantly over the years, its centralized logic is accompanied by a number of problems. Firstly, users are required to trust their personal data to the administrative authority of the respective application. Maintaining full control over them, the latter gains the ability to process, share and censor them, either to serve its own interests or to comply with other authorities in power. Furthermore, there is no guarantee of data availability, as, at any time, the server can be disconnected indefinitely and for a variety of reasons, such as a cyber attack or a natural disaster.

-These are some of the key factors that have led to the rapid development of a wide range of innovating open source software, that are based on technologies such as blockchain and peer-to-peer networks. The aforementioned technologies, although at a relatively early stage, are already powerful tools for creating distributed and decentralized applications.

+The goal of this thesis is the implementation of an autonomous social platform by utilizing decentralization technologies. This implementation will firstly return the ownership of the data to the end user and secondly provide transparent democratic voting processes. The above are provided in a context resistant to both faults and attacks, as well as attempts at censorship and falsification.
-which, by utilizing decentralization technologies, on the one hand will return the ownership of the data to the end user, on the other hand will provide transparent democratic voting processes. These in a context resistant to both faults and attacks, as well as attempts at censorship and falsification.
 
-The developed proof of concept application "Concordia" approaches the above goal by combining Ethereum and IPFS, in order to define a digital space, that is decentralized both at architectural and political level.
