![]() As Tor uses SOCKS, I2P tends to fare better for security than Tor, but keep in mind most people will not have a threat model where this would be of concern, as attacks tend to be highly complex. Also along these lines, I2P's API was created for anonymity, unlike SOCKS, which is designed for functionality. Essentially, all peers participate in routing for others. This means transparent load balancing of messages across multiple peers, rather than a single path. I2P is packet switched, instead of circuit switched, like the Tor network. Helping this is the fact that peers are selected by continuously profiling and ranking performance, rather than trusting claimed capacity. I2P was designed and optimized for hidden services, which are much faster than in Tor, as the network is fully distributed and self-organizing. ![]() This is the fundamental difference between I2P and the Tor network. Steps have been taken to provide a better environment for hosting services rather then providing out-proxies. I2P was designed with the internal network in mind. This centralization reduces complexity at each node and can efficiently address Sybil attacks. Tor takes the directory-based approach, providing a centralized point to manage the overall 'view' of the network, as well as gather and report statistics, as opposed to I2P's distributed network model. This means that the Tor client typically runs faster and with a smaller memory footprint. On that note, Tor is written in C, as opposed to I2P's Java. In fact, Tor receives a good amount of money for its maintenance and development, and this shows in the form of its excellent documentation and white papers. Tor also has advantages in that it holds a large number of talented developers, some of them are even funded. Tor is a simple SOCKS proxy, so your only choice is to be a relay, exit node, or client node. The only reason anyone would be changing the I2P config would be to set up port forwarding, and that's a bit out of this article's scope (though a great idea for a future one). This is because there are many more exit nodes on the Tor network then on I2P, and with the ability to use TLS and bridges, Tor also performs better at evading state-level firewalls (think China and Iran). In my Tor article, I mentioned it was better designed as an out-proxy than I2P is. As a result, it has been studied much more in depth by both the white hat and black hat communities. Tor has been around quite a while longer then I2P. Let's take a look at each in more detail. It's how this is performed that draws its contrasts. This way, each router can only see the router that sent it the packets and the router it in turn must send the packets to. However, they achieve this in slightly different ways.Īs a quick recap, onion routing involves wrapping your packets in multiple layers of encryption, in a system where each router that passes it along only has the key to decrypt its layer and none of the others. Tor and I2P are both anonymizing networks, allowing people to tunnel out of their open and non-secure environments. But first, let's take a brief jump back into the Deep Web to better explain these tools in order to give you the knowledge to make more informed choices. With this article, I am going answer those questions and better explain the pros and cons of each, breaking down the networks, pitfalls, and things you should know to be safe. I'd like to thank all of you for letting me know what was on your minds, as you should always! While my initial four articles were meant as an introduction, I ended up receiving a lot of interesting comments and messages asking the technical differences between the two. ![]() I covered the two largest anonymity networks on the Internet today, Tor and I2P. Mattermost is an open source platform for secure collaboration across the entire software development lifecycle.In my recent Darknet series, I attempted to connect the dots on the Deep Web. I2P+ is a soft-fork of the Java I2P Anonymizing Network Layer - this is a mirror of Lokinet is an anonymous, decentralized and IP based overlay network for the internet. RetroShare is a Free and Open Source cross-platform, Friend-2-Friend and secure decentralised communication platform. □ I2P: End-to-End encrypted and anonymous Internet Starting from an application for secure publication of files, it has grown to include all kinds of basic protocol components and applications towards the creation of a GNU internet. Our goal is to replace the old insecure Internet protocol stack. GNUnet is an alternative network stack for building secure, decentralized and privacy-preserving distributed applications. ![]() ZeroNet - Decentralized websites using Bitcoin crypto and BitTorrent network When comparing Freenet and i2p.i2p you can also consider the following projects: ![]()
