ZeroNet is a very powerful system for decentralized distributed dynamic web sites and services. The user starts downloading and seeding website data upon visiting it, following BitTorrent principle. But unlike other similar systems, ZeroNet allows creating full-fledged blogs with comments, forums, video hostings, wiki sites, chats, email and git.
ZeroNet splits website data from website code: the data is stored in .json files and combined into sqlite databases with defined scheme, which allows to implement mind-bending features: local search in all opened websites in a meaning of milliseconds, all-site real-time RSS-like update stream.
ZeroNet provides standardized authentication system similar to OAuth, NAT and Tor support.
The system works really fast, is user-friendly, has modern user interface with small but convenient features like global night/day theme switch for all sites.
I believe that ZeroNet is underrated and intentionally uploaded silent version of the disk only to ZeroNet Git, to attract new users.
