RetroShare is much more than a backup for centralized solutions. It is a self-organizing network, where malicious actors are marginalized by majority vote and eventually excluded.
You are free to create your own channels. There is no hierarchy. Private groups/chats/channels/circles/nodegroups can be created, too.
The bright nodes are ON 24/7 (our own IDs) and the dark nodes are occasional visitors (1st degree separation). Any of +2000 nodes worldwide can be used to access public boards
In the boot phase we are invitation only. If you want to help testing reply here and get an invitation PM. Don't send me PMs from other lemmy instances --- had to ban due to spam. PMs from monero.town are fine.
