What is Freenet?
- Online threats
- VPN
Overview
Freenet is a free, decentralized, peer-to-peer platform designed for anonymity and anti-censorship purposes. It allows users to share, browse, and search for information on the internet without relying on any central servers or authoritative entities. Freenet's main goals are to protect user privacy and freedom of speech while promoting knowledge dissemination and innovation.

How does Freenet work?
Freenet operates based on a Distributed Hash Table (DHT) , which is a technique to store data across multiple nodes in the network. Each node has a unique identifier called a key and a storage space called data storage. When users want to upload or download data, they use a software client called Freenet node to connect to other nodes in the network. Freenet nodes route the data to the node closest to the corresponding key based on a certain function between the key and the data. As a result, data can be stored and retrieved in a dispersed manner across the network without the need to know the specific location or content of the data.
Features of Freenet
① Decentralized
Freenet operates without any central servers or authoritative entities. It is entirely composed and maintained by users, making it resistant to government control or interference and continuing to function even if individual nodes fail.
② Anonymous
Freenet employs complex encryption and routing algorithms to protect user identity and communications. Users do not need to register or log in, and no traceable information is left behind. Freenet offers two modes: Opennet and Darknet. In Opennet mode, users can randomly connect to any node in the network, while in Darknet mode, they can only connect to nodes they trust. Darknet mode provides greater security and privacy but may make it harder to discover new nodes.
③ Anti-censorship
Freenet utilizes a technique called redundant encoding to protect data from deletion or modification. Redundant encoding involves dividing data into multiple fragments and adding extra information to each fragment so that even if some fragments are lost or damaged, the original data can be recovered from the remaining fragments. This ensures data integrity and availability even if attempts are made to delete or modify certain data.
④ Dynamic
Freenet is a dynamically changing network that adapts based on user needs and behaviors. For example, Freenet allocates storage space and bandwidth based on data popularity and importance, and it optimizes routing strategies and security measures according to network conditions and attack situations. This enables Freenet to adapt to different environments and challenges, improving its performance and stability.
Comparison of Freenet and VPN
Although both Freenet and VPN can help users achieve anonymity and anti-censorship on the internet, they have their respective advantages and disadvantages. Here's a brief comparison:
Advantages of Freenet:
① Completely free, no need for payment or registration.
② Fully decentralized, no reliance on any central servers or authoritative entities.
③ Fully anonymous, no need to disclose any identity or communication information.
④ Completely anti-censorship, unable to delete or modify any data.
Advantages of VPN :
① Fast speeds, no waiting for data transmission in the network.
② Good compatibility, can access any website or service.
③ Easy to use, only need to install a software or application.
④ Flexible and diverse, can choose different servers.
Disadvantages of Freenet:
① Slow speeds, need to wait for data transmission in the network.
② Poor compatibility, can only access content on Freenet.
③ Complex and challenging to use, requiring installation and configuration of a software client.
④ Potential risks, may encounter illegal or malicious content or nodes.
Disadvantages of VPN:
① Not free, requires payment or registration.
② Not decentralized, reliant on specific central servers or authoritative entities.
Why do we recommend MetroVPN?
Based on the above comparison, we can see that both Freenet and VPN have their pros and cons, and there is no perfect solution. Therefore, we recommend that you choose the appropriate tool to protect your privacy and freedom of speech based on your needs and circumstances. If you want to browse and share sensitive or restricted content on the internet, Freenet might be a good option. However, if you simply want to access restricted or blocked websites or services on the internet, MetroVPN might be a better choice.
