Here are some key features of "Osiris":

· Indestructible: The data of the portals are not saved on a single computer, each member of the portal has a copy of them on his hard disk. The same parts of the portal are saved on many connected units, in order to avoid compromising the integrity of the portal if one of them disconnects. This ensures that a portal built with Osiris will last forever.
· Dependability: A portal made with Osiris has many copies of itself on the net, with the guarantee that in case of hardware failure (Broken hard disk, Virus...) it can be rebuilt from another copy. You are not asked for an internet connection to browse it because the data are on your computer. This ensures exceptional speed (You'll be asked for an internet connection if you want to add a contribute).The more people use your portal, the more it will be sure and fast.
· Economical: Osiris allows you to open your portal for free, without the need of an housing/hosting service because the resources are shared by the users registered to the portal.
· Anonymous: In the portal the real user can create as many virtual identities as he want. It's possible to trace the virtual identity which has contributed to the portal, but is impossible to trace the real one, because Osiris doesn't make a difference between the writer and the distributer. Anyway we are talking about reserve, not anonymity, the IP addresses can be seen by anyone, but they cannot be associated with a single user. A bigger portal ensures more anonymity than a small one.
· Safe: A digital signature system ensures continuity to the discussions. Even if we don't know who a user really is, we know that a series of messages have been written by the same person.
· Transparent: Unlike other similar systems, anyone is free to see in clear all contents stored in local and share them, and anyone is free to decide if a content need to be censured or not.
· Anarchic: All the users have the same powers, the portal doesn't have a centralized administration. Anyone can read, write or edit comments and posts. This means that anyone can express his thought, and no one can censor it. Users can only suggest that a particular comment should not be there and propose a censorship, that will be done only if the whole community agree. In order to avoid spammers, Osiris uses a Reputation system, used to create filters for the portal contents. Anyway, you can always create a regular forum, with administrators and moderators.
