How does Freenet Work?
Freenet operates through a decentralized network of nodes distributed across multiple machines, where encrypted data is stored and retrieved collaboratively by users.
Essentially, users share their unused hard drive space to contribute to the storage and retrieval of information. To interact with the network, users utilize a program that combines the functionalities of a web browser and a file-sharing client.
When a user requests information or initiates file sharing, the requested files are divided into smaller chunks and distributed across numerous nodes within the Freenet network.
This decentralized storage approach ensures redundancy and enhances data availability. Additionally, the encryption employed by Freenet makes it extremely difficult to track the origin or destination of data requests.
Consequently, it becomes nearly impossible to determine the source of a request for a particular node or where the requested data is ultimately headed. This robust encryption mechanism reinforces user privacy and anonymity within the Freenet ecosystem.
What is Hyphanet?
Hyphanet, derived from Freenet, originated as a student project led by Ian Clarke. The project led to the publication of a seminal paper in 2001 titled “Freenet: A Distributed Anonymous Information Storage and Retrieval System,” which garnered significant attention within the computer science community in 2002.
Distinguishing itself from other dark web technologies like Tor and I2P, Hyphanet serves as a pure dark web platform with no access to the regular internet. It operates as a fully distributed, peer-to-peer network focused on anonymous publishing and secure data storage.
Upon joining the Hyphanet network, users agree to allocate a portion of their local disk space, referred to as a datastore, for secure encryption and sharing. Other Hyphanet members can then download fragments of files from these datastores, akin to the mechanism of BitTorrent.
While Hyphanet’s core framework supports basic file hosting, volunteer developers have extended its functionality to encompass features like websites and message boards. However, due to inherent limitations, websites on Hyphanet are static and lack dynamic content.
An advantage of Hyphanet lies in its ability to preserve web pages and data even after the original host disappears. Nevertheless, inactive data may eventually become inaccessible, akin to the de-indexing process observed in BitTorrent when files are no longer seeded actively.
