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. First of all, the user is required to trust his personal data to an external entity. 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. In addition, 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 technologiew such as blockchain and peer-to-peer networks. The above, although at a relatively early stage, are already powerful tools for creating distributed and decentralized applications. |

The aim of this thesis is the implementation of an autonomous social platform, |
|||
which, by utilizing decentralization technologies, on the one hand will return the ownership of the staff |
|||
user data, on the other hand, will enable transparent democratic voting processes. These in a context resistant to both faults and attacks, as well as attempts at censorship and falsification. |

The goal of this thesis is the implementation of an autonomous social platform, |
|||
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 decentralized digital space, both at architectural and political level. |

Το άρθρωμα drizzle που χρησιμοποιείται στην υπηρεσία \hyperref[subsection:4-3-2-concordia-application-service]{Concordia Application} είναι μία τροποποιημένη έκδοση της Javascript βιβλιοθήκης Drizzle (και συγκεκριμένα του @drizzle/store\footnote{\url{https://github.com/trufflesuite/drizzle/tree/develop/packages/store}}), η οποία προσφέρεται από τη σουίτα εργαλείων Truffle. Η τροποποιημένη βιβλιοθήκη αναπτύχθηκε στα πλαίσια της διπλωματικής με στόχο τη διευκόλυνση της χρήσης του Drizle και την επιδιόρθωση προβληματικών σημείων της πρωτότυπης βιβλιοθήκης. |

Το άρθρωμα drizzle υλοποιεί τις προγραμματιστικές διεπαφές μέσω των οποίων πραγματοποιείται η επικοινωνία της εφαρμογής με το blockchain. Για την επίτευξη της επικοινωνίας αυτής, η βιβλιοθήκη χρησιμοποιεί τη συλλογή βιβλιοθηκών web3.js η οποία αποτελεί τον πιο διαδεδομένο τρόπο διεπαφής με το blockchain σε αποκεντρωτικές εφαρμογές. Τελικά, παρέχει ένα Redux store, το οποίο συμπεριλαμβάνεται στο κεντρικό store της εφαρμογής. |
