+# Vision
+
+## Une plateforme pour tous
+
+Le but de Nexus est de créer un environnement entre le chat youtube (ou plein de gens discutent temporairement et ne se connaissant pas) et un réseau social (ou les gens n'ont pas de place pour discuter vraiment), qui s'appuie sur la blockchain pour la confidentialité et des evenements numériques cool.
+Le but est de faire de vrai salons numériques, des clubs 2.0, ou les utilisateurs se rencontrent et sont amenés à se connaitre.
+
+Une musique vidéo est jouée en fond (differents styles selon les salons) pour l'aspect cosy et etre sur que tout le monde ecoute la meme chose.
+
+## Un fonctionnement décentralisé
+
+La plateforme requiert un login via phantom (+ de wallet à venir) avec une addrese Solana. La platfeforme utilise un token $PLEXUS pour fonctionner. Envoyer un message coute 1$PLEXUS (cout bas mais trace sur la blockchain), chaque message contient ainsi une transaction id qui vérifie que le user à bien dépensé 1$PLEXUS pour envoyer son message.
+
+Changer de username coute 30$PLEXUS et les utilsateurs peuvent choisir une photo de profil NFT.
+
+
+## Des salons détenus par les membres
+
+Le salon doit etre la propriété des membres. des règles / parametres du salon sont gérés par les membres. Chaque salon a donc ses propres règles. Ouvert ou fermé, nombre de membres max, qui est le ou les modérateurs (important pour que le site ne devienne pas un repaire de voleurs / arnaqueurs / criminels), la gouvernance (un chef qui décide, des membres qui votent, votent à la proportionnelle du token, ... ), Les règes du salon, le prix du membership (et le temps de membership, tous sont temporaires car si quelqu'un s'en va, la place ne reste pas bloquée) ..., on peut également imaginer un "pot commun" (récompensees d'evenements, stacker pour gagner des bonus (des emotes, des NFT, ...) )
+
+Des evenements seront organisés, distribuant des $PLEXUS, des NFT, ... . L'aspect communautaire est important, l'aspect cool de la plateforme (l'image) est ULTRA importante.
+Des compétitions entre salons, ... .
+
+
+## Un réeau social
+
+Les membres ont une page personnel qu'ils peuvent mettre à jour / customiser, faire des posts, ... envoyer des messages privés, ... .
+
+
+## Pour aller plus loin
+
+On peut imaginer un boutton IA qui peut lire les messages pour les résumer à la demande de l'utilisateur, ...
