==List of anonymous P2P networks and clients==
{{See also|Comparison of file sharing applications}}
<!-- Please keep this list in alphabetical order -->
<!-- Please do not add any applications which do not allow file transfer without anybody knowing your IP. Having a proxy which takes the blame is NOT anonymous, private nets are NOT anonymous -->

===Public P2P clients===
* Classified-ads - an [[Open-source software|open source]] DHT-based decentralized messaging and voice app. Allows users to not expose any personal details but does not hide network addresses of nodes.
* DarkMX<ref>{{Cite web |url=https://darkmx.app/ |title=DarkMX |access-date=2022-03-29 |archive-date=2022-02-10 |archive-url=https://web.archive.org/web/20220210110604/https://darkmx.app/ |url-status=live }}</ref> - a file-sharing client modeled on [[WinMX]]/[[Tixati]] with a built-in implementation of Tor.
* [[CryptoNote#DigitalNote .28XDN.29|DigitalNote XDN]] - an open-source anonymous [[Decentralized computing|decentralized]] encrypted messaging system based on blockchain technology
* [[Freenet]] - a censorship-resistant [[distributed file system]] for anonymous publishing (open source, written in Java)
* [[GNUnet]] - a P2P [[Software framework|framework]], includes anonymous file sharing as its primary application ([[GNU Project]], written in C, alpha status)
* [[Perfect Dark (P2P)|Perfect Dark]] - a Japanese file-sharing client based on a distributed data store.  One can see the IP address of connected nodes, but not what they are up or downloading.  Amoeba<ref>{{Cite web|url=https://archive.org/details/amoeba_5.1.8|title = Amoeba 5.1.8 (The next generation P2P file sharing software)}}</ref> is a similar client/network.
* [[Tribler]] - an [[Open-source software|open source]] [[BitTorrent]] [[Client (computing)|client]]. It can be set to have neighboring nodes act as proxies between one's client and the torrent swarm.  The proxy can see what file is being uploaded, but most nodes in the swarm only see the exit node.
* [[ZeroNet]] - a decentralized [[Internet]]-like [[computer network|network]] of peer-to-peer users. Allows tunneling of HTTP-traffic through Tor.

====I2P clients====
* [[I2P]] - a fully [[Decentralized computing|decentralized]] overlay network for strong anonymity and [[end-to-end encryption]], with many applications (P2P, browsing, distributed anonymous e-mail, [[instant messaging]], [[Internet Relay Chat|IRC]], ...) running on top of it (free/open source, platform-independent)
* [[I2P#Email|I2P-Bote]] an anonymous, secure (end-to-end encrypted), serverless mail application with remailer functionality for the I2P network
* [[I2P#Instant messaging|I2P-Messenger]] an anonymous, secure (end-to-end encrypted), serverless instant messenger for the I2P network
* [[I2P#File sharing|I2PSnark]] - an anonymous [[BitTorrent (protocol)|BitTorrent]] client for the I2P network
* [[I2Phex]] - a [[Gnutella]] client which communicates anonymously through I2P
* iMule - an [[aMule]] port running under I2P network
* [[Robert (P2P Software)]] - another anonymous [[BitTorrent (protocol)|BitTorrent]] client for the I2P network
* [[Tahoe-LAFS|I2P-Tahoe-LAFS]] - a censorship-resistant [[distributed file system]] for anonymous publishing and file sharing (open source, written in Python, pre-alpha status)
* [[Vuze]] (formerly Azureus) -  a [[BitTorrent client]] with the option of using [[I2P]] or [[Tor (anonymity network)|Tor]] (initially open source, written in Java)
* [[BiglyBT]] -  a successor to [[Vuze]]. A [[BitTorrent client]] where downloads can be routed through [[I2P]], and searches carried out through [[Tor (anonymity network)|Tor]] (open source, written in Java)
* MuWire<ref>{{Cite web |title=MuWire - Easy Anonymous File Sharing |url=https://muwire.com/ |url-status=live |archive-url=https://web.archive.org/web/20200823094455/https://muwire.com/ |archive-date=2020-08-23 |access-date=2020-08-22 |website=muwire.com}}</ref> - is a filesharing software, with chat rooms. Even if running inside the I2P network, it is not called a 'I2P client' because it has a I2P router embedded, so this makes it a standalone software. The project got shut down on 14 February 2023<ref>{{cite web |title=Shutdown notice and Java I2P warning (#178) · zlatinb/Muwire@8dbd094 |url=https://github.com/zlatinb/muwire/commit/8dbd0944ff07780a73d6895f8455e1da0e60db61 |website=[[GitHub]]}}</ref> but recently it seemingly got unarchived on Github, the developer said that it is possible to import connections from a .txt file for MuWire to work, which is now provided in the releases.<ref>{{Cite web |title=Update README.md with instructions to import connections from a friend · zlatinb/muwire@651c9f3 |url=https://github.com/zlatinb/muwire/commit/651c9f3e944b07adf92fb2ac6d74eaa31423eff5 |access-date=2024-08-23 |website=GitHub |language=en}}</ref>

===Private P2P clients===
[[Private P2P]] networks are P2P networks that only allow some mutually trusted computers to share files. This can be achieved by using a central server or [[Direct Connect (protocol)#Hublists|hub]] to authenticate clients, in which case the functionality is similar to a private [[File Transfer Protocol|FTP]] server, but with files transferred directly between the clients. Alternatively, users can exchange passwords or keys with their friends to form a decentralized network.

Examples include:
* [[Syncthing]] - is a [[free software|free]], [[open source software|open-source]] [[peer-to-peer]] [[file synchronization]] application. It can sync files between devices. Data security and data safety are built into the design of the software.
* [[Resilio Sync]] - a proprietary alternative to [[Syncthing]]

===Private F2F (friend-to-friend) clients===
[[Friend-to-friend]] networks are P2P networks that allows users only to make direct connections with people they know. Passwords or digital signatures can be used for authentication.

Examples include :
* [[Filetopia]] - not anonymous but encrypted friend-to-friend. File sharing, chat, internal mail service
* [[OneSwarm]] - a backwards compatible BitTorrent client with privacy-preserving sharing options, aims to create a large F2F network.
* [[Retroshare]] - filesharing, serverless email, instant messaging, VoIP, chatrooms, and decentralized forums.

===Hypothetical or defunct networks===

====Hypothetical====
The following networks only exist as design or are in development
* [[anoNet]] - extensible IP anonymizer with steganography support (in development)
* [[Crowds (anonymity network)|Crowds]] - Reiter and Rubin's system for "blending into a crowd" has a known attack
* [[P2PRIV]] - Peer-to-Peer diRect and anonymous dIstribution oVerlay - anonymity via virtual links parallelization - currently in development and has significant, unsolved problems in a real world environment

* Race ([[Resilient Anonymous Communication for Everyone]]) - A project by DARPA to build an anonymous, attack-resilient mobile communication system that can reside completely within a network environment, capable of avoiding large-scale compromise by preventing compromised information from being useful for identifying any of the system nodes because all such information is encrypted on the nodes at all times, even during computation; and preventing communications compromise by virtue of obfuscating communication protocols.

===Anonymous P2P in a wireless mesh network===
It is possible to implement anonymous P2P on a [[wireless mesh network]]; unlike fixed Internet connections, users don't need to sign up with an ISP to participate in such a network, and are only identifiable through their hardware.

Protocols for [[wireless mesh network]]s are [[Optimized Link State Routing Protocol]] (OLSR) and the follow-up protocol [[B.A.T.M.A.N.]], which is designed for decentralized auto-IP assignment. See also [[Netsukuku]].

Even if a government were to outlaw the use of wireless P2P software, it would be difficult to enforce such a ban without a considerable infringement of personal freedoms. Alternatively, the government could outlaw the purchase of the wireless hardware itself.
