I2P

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.

As far as I'm aware, this anonymous overlay network has recieved few if any audits from a reputable source. They're slow but meticulous in their development cycles. Such a system isn't as easy to configure as something like the Tor Browser, but is just as easy to initially setup. I recommend for scholars, developers wishing to help, and those who are just curious. (Side note: This project has been bundled into TAILS, or The Amnesic Incognito Live System, which likely warrents some inherent value to the privacy and anonymity people can achieve with this service/program.) I may release a full fledged review in the future.

The I2P network is great, but this software is written in Java (so, slow and eating many resources) and obsolete. Happyfully, there is a great alternative written in C++: i2pd.

So far I get a Win 10 error message, "can not find javaw".. I got that on both my computers.

'The main I2P client implementation uses Java.' - so you have to install it. If you've already done it, try to reinstall it.

Amazing in theory, disappointment is practice. I2P has too little content because there are few users, and few users because there is little content. No one needs anonymity if there is nothing to do on the network. It's a vicious circle that will never allow I2P to be anything revolutionary.

The I2P network contains more sites than you think. See reg.i2p, notbob.i2p, isitup.i2p, et cetera.

But the Java I2P software is obsolete, see the much better i2pd written in C++.

I2P, Freenet & ZeroNet are entire ecosystems each one. They are not only gates to circumvent censorship and you can't use them as VPNs.

The idea that you can go to a website, without being able to discover who or where they are, and conversely without them being able to identify you, is absolutely amazing. The I2P ecosystem, in my brief exposure to it, is functional but exceedingly slow and unreliable, even when compared with Tor which has some similar properties. Also the address book system and lookup services seems a bit clunky. I hope this improves as more people start to get involved and use the system, because it feels like an important step towards freedom on the Internet.

What is I2P?

I2P is an anonymizing network, offering a simple layer that identity-sensitive applications can use to securely communicate. All data is wrapped with several layers of encryption, and the network is both distributed and dynamic, with no trusted parties.

Many applications are available that interface with I2P, including mail, peer-peer, IRC chat and others.

Alternative i2p Clients: https://geti2p.net/en/about/alternative-clients

The main I2P client implementation uses Java. If for some reason you can't use Java on your device, there are alternative implementations developed by community members.

i2pd i2pd is a I2P client implementation in C++. As of early 2016, i2pd is became stable enough to be used in production, and since summer 2016 it fully implements all I2P APIs.

Kovri Kovri is active i2pd fork developed for Monero cryptocurrency.

Go-I2P Go-I2P is I2P client developed using the Go programming language. The project is in early development.
