As far a second-generation Freenet, I heard i2p started out as a proposed re-factoring and generalization of Freenet's encrypted transport layer. Are there any plans on using i2p to carry Freenet traffic?
This is correct - while old and new Freenet both rely on a small-world network, they are very different and not compatible. Borrowing from our FAQ[1], the main differences are:
Functionality: The previous version of Freenet (now called Hyphanet) was analogous to a decentralized hard drive, while the current version is analogous to a full decentralized computer.
Real-time Interaction: The current version allows users to subscribe to data and be notified immediately if it changes. This is essential for systems like instant messaging or group chat.
Programming Language: Unlike the previous version, which was developed in Java, the current Freenet is implemented in Rust. This allows for better efficiency and integration into a wide variety of platforms (Windows, Mac, Android, MacOS, etc).
Transparency: The current version is a drop-in replacement for the world wide web and is just as easy to use.
Anonymity: While the previous version was designed with a focus on anonymity, the current version does not offer built-in anonymity but allows for a choice of anonymizing systems to be layered on top.
I can even remember my Motorola Razr being arguably (almost) a smartphone because, while a far cry from Symbian, it could already run Java applications ! (Notably, IIRC, Opera mini ?)
P.S.: Also, I tried Freenet about around that time too ! I'm a bit confused about this being a "new" project... why not naming it "Freenet 2" then ? Why did Freenet "1" had to change its name ??
I2P was created by someone who was previously involved with Freenet, but its design is a lot closer to Tor than to Freenet. Both I2P and Tor are anonymizing proxies, they allow services to be hidden, but they're still centralized.
While they are quite different, there is enough overlap that running Freenet over I2P (or Tor) would be wildly inefficient and slow, so I wouldn't recommend it. Freenet is designed to run over UDP directly.
The new Freenet is designed to allow the creation of completely decentralized services. Briefly, it's a global key-value store in which keys are webassembly code that specify what values are permitted under that key, and the conditions under which those values can be modified. This key-value store is observable, so anyone can subscribe to a key and be notified immediately if the value changes.
This is just scratching the surface, for anyone interested in a much more comprehensive explanation of the new Freenet please see this talk I gave a few months ago: [1] You can also find a FAQ here: [2]
