ZeroNet uses cryptography (Bitcoin library) and BitTorrent DHT (centralized trackers) to build a distributed censorship-resistant network.
The I2P network provides strong privacy protections for communication over the Internet. Many activities that would risk your privacy on the public Internet can be conducted anonymously inside I2P.
IPFS is a global, versioned, peer-to-peer filesystem. It combines ideas from Git, BitTorrent, Kademlia, SFS, and the web. It is like a single bittorrent swarm, exchanging git objects. IPFS provides an interface as simple as the HTTP web, but with permanence built in.
Hyphanet (former Freenet) is free software which lets you anonymously share files, browse and publish "freesites".
GNUnet is a framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. A first service implemented on top of the networking layer allows anonymous censorship-resistant file-sharing.
Hypercore Protocol is a peer-to-peer data network built on the Hypercore logs. Hypercores are signed, append-only logs. They're like lightweight blockchains without the consensus algorithm. As with BitTorrent, as more people "seed" a dataset it will increase the...
dn42 is a big dynamic VPN, which employs Internet technologies (BGP, whois database, DNS, etc). Participants connect to each other using network tunnels (GRE, OpenVPN, Tinc, IPsec) and exchange routes thanks to the Border Gateway Protocol.
Librevault is an open-source peer-to-peer file synchronization program, designed with convenience and privacy in mind. Our goal is to make a better alternative to BitTorrent Sync and Syncthing.
Beaker is a an experimental peer-to-peer web browser based on Hyper protocol. It's licensed MIT, and supports plugins for adding new protocols and Web APIs.
