# About Concordia |
||||
|
|
||||
|
## What |
||||
|
|
||||
|
Concordia is a forum platform (remember forums? 🤩) that focuses on user privacy and direct democratic voting. It is a |
||||
|
FOSS distributed via its Gitlab [repository][concordia-repository] and Docker [repository][concordia-docker-hub] under |
||||
|
the [MIT][concordia-license] license. |
||||
|
|
||||
|
## Why |
||||
|
|
||||
|
The value of privacy, freedom of speech and democracy are diminishing in modern software. Even more so in social media |
||||
|
platforms. Users are called to select between being the product of companies that sell their personal information and |
||||
|
being shut out of the modern, digital society. |
||||
|
|
||||
|
Concordia, much like other projects of this kind, provides an alternative to this predicament. |
||||
|
|
||||
|
## How |
||||
|
|
||||
|
Concordia uses decentralized technologies, namely the Ethereum blockchain and its smart contracts, as well as the |
||||
|
distributed database OrbitDB that's based on the decentralized network IPFS. These technologies make Concordia |
||||
|
impervious to censorship and guaranty the immutability of user information and anonymity while enabling user |
||||
|
authentication that makes trusted, direct voting possible. |
||||
|
|
||||
|
You can read more about the technological stack in Concordia's [whitepaper][concordia-whitepaper]. |
