What is Freenet?

Freenet is free software which lets you publish and obtain information on the Internet without fear of censorship. To achieve this freedom, the network is entirely decentralized and publishers and consumers of information are anonymous. Without anonymity there can never be true freedom of speech, and without decentralization the network will be vulnerable to attack.

Communications by Freenet nodes are encrypted and are “routed-through” other nodes to make it extremely difficult to determine who is requesting the information and what its content is.

Users contribute to the network by giving bandwidth and a portion of their hard drive (called the “data store”) for storing files. Unlike other peer-to-peer file sharing networks, Freenet does not let the user control what is stored in the data store. Instead, files are kept or deleted depending on how popular they are, with the least popular being discarded to make way for newer or more popular content. Files in the data store are encrypted to reduce the likelihood of prosecution by persons wishing to censor Freenet content.

The network can be used in a number of different ways and isn’t restricted to just sharing files like other peer-to-peer networks. It acts more like an Internet within an Internet. For example Freenet can be used for:

* Publishing websites or ‘freesites’
* Communicating via message boards
* Content distribution
* Sending email messages

Unlike many cutting edge projects, Freenet long ago escaped the science lab, it has been downloaded by over 2 million users since the project started, and it is used for the distribution of censored information all over the world including countries such as China and the Middle East. Ideas and concepts pioneered in Freenet have had a significant impact in the academic world. Our 2000 paper “Freenet: A Distributed Anonymous Information Storage and Retrieval System” was the most cited computer science paper of 2000 according to Citeseer, and Freenet has also inspired papers in the worlds of law and philosophy. Ian Clarke, Freenet’s creator and project coordinator, was selected as one of the top 100 innovators of 2003 by MIT’s Technology Review magazine.

The Philosophy behind Freenet

1. A Disclaimer
There are many reasons why people get involved in the Freenet Project. Some share the views outlined in this document; some share variations of these views, which are also served by what we are trying to achieve; and some just enjoy the technical challenge. These are the ideas which motivated me to architect the system in the first place, but not necessarily the views that everyone involved in the Freenet project holds.

2. Suggested prior reading
For this document to make sense, you should probably know what Freenet is. You can get a good overview on the What is Freenet? page.

3. The importance of the Free flow of information
Freedom of speech, in most western cultures, is generally considered to be one of the most important rights any individual might have. Why is the freedom to share ideas and opinions so important? There are several ways to answer this question.

3.1 Communication is what makes us human
One of the most obvious differences between mankind and the rest of the animal kingdom is our ability to communicate sophisticated and abstract concepts. While we constantly discover that animal’s communication ability is more sophisticated than previously assumed, it is unlikely that any other animal approaches our own level of ability in this area.

3.2 Knowledge is good
Most people, given the option of knowing something and not knowing something, will choose to have more information rather than less. Wars have been won and lost over who was better-informed. This is because being better-informed allows us to make better decisions, and generally improve our ability to survive and be successful.

3.3 Democracy assumes a well informed population
Many people today live under democratic governments, and those who don’t, probably want to. Democracy is an answer to the question of how to create leaders, while preventing them from abusing that power. It achieves this by giving the population the power to regulate their government through voting, yet the ability to vote does not necessarily mean that you live in a democratic country. For a population to regulate their government effectively it must know what their government is doing, they must be well informed. It is a feedback loop, but this loop can be broken if the government has the power to control the information the population has access to.

4. Censorship and freedom
Everyone values their freedom, in fact, many consider it so important that they will die for it. People like to think that they are free to form and hold whatever opinions they like, particularly in western countries. Consider now that someone had the ability to control the information you have access to. This would give them the ability to manipulate your opinions by hiding some facts from you, by presenting you with lies and censoring anything that contradicted those lies. This is not some Orwellian fiction, it is standard practice for most western governments to lie to their populations, so much so, that people now take it for granted, despite the fact that this undermines the very democratic principles which justify the government’s existence in the first place.

5. The solution
The only way to ensure that a democracy will remain effective is to ensure that the government cannot control its population’s ability to share information, to communicate. So long as everything we see and hear is filtered, we are not truly free. Freenet’s aim is to allow two or more people who wish to share information, to do so.

6. Isn’t censorship sometimes necessary?
Of course no issue is black and white, and there are many who feel that censorship is a good thing in some circumstances. For example, in some European countries propagating information deemed to be racist is illegal. Governments seek to prevent people from advocating ideas which are deemed damaging to society. There are two answers to this however. The first is that you can’t allow those in power to impose “good” censorship, without also enabling them to impose “bad” censorship. To impose any form of censorship a government must have the ability to monitor and thus restrict communication. There are already criticisms that the anti-racism censorship in many European countries is hampering legitimate historical analysis of events such as the second world war.

The second argument is that this “good” censorship is counter-productive even when it does not leak into other areas. For example, it is generally more effective when trying to persuade someone of something to present them with the arguments against it, and then answer those arguments. Unfortunately, preventing people from being aware of the often sophisticated arguments used by racists, makes them vulnerable to those arguments when they do eventually encounter them.

Of course the first argument is the stronger one, and would still hold-true even if you didn’t accept the second. Basically, you either have censorship, or you don’t. There is no middle-ground.

7. But why is anonymity necessary?
You cannot have freedom of speech without the option to remain anonymous. Most censorship is retrospective, it is generally much easier to curtail free speech by punishing those who exercise it afterward, rather than preventing them from doing it in the first place. The only way to prevent this is to remain anonymous. It is a common misconception that you cannot trust anonymous information. This is not necessarily true, using digital signatures people can create a secure anonymous pseudonym which, in time, people can learn to trust. Freenet incorporates a mechanism called “subspaces” to facilitate this.

8. And what of copyright?
Of course much of Freenet’s publicity has centered around the issue of copyright, and thus I will speak to it briefly. The core problem with copyright is that enforcement of it requires monitoring of communications, and you cannot be guaranteed free speech if someone is monitoring everything you say. This is important, most people fail to see or address this point when debating the issue of copyright, so let me make it clear:

You cannot guarantee freedom of speech and enforce copyright law

It is for this reason that Freenet, a system designed to protect Freedom of Speech, must prevent enforcement of copyright.

9. But how will artists be rewarded for their work without copyright?

Firstly, even if copyright were the only way that artists could be rewarded for their work, then I would contend that freedom is more important than having professional artists (those who claim that we would have no art do not understand creativity: people will always create, it is a compulsion, the only question is whether they can do it for a living).

Secondly, it could be questioned whether copyright is effective even now. The music industry is one of the most vocally opposed to enhancements in communication technology, yet according to many of the artists who should be rewarded by copyright, it is failing to do so. Rather it has allowed middle-men to gain control over the mechanisms of distribution, to the detriment of both artists and the public.

10. Alternatives to Copyright

Fortunately it won’t come to this. There are many alternative ways to reward artists. The simplest is voluntary payment. This is an extension of the patronage system which was frequently used to reward artists prior to copyright, where a wealthy person would fund an artist to allow them to create full-time. The Internet permits an interesting extension of this idea, where rather than having just one wealthy patron, you could have hundreds of thousands, contributing small amounts of money over the Internet.

We actually practice what we preach in this regard too, on the 15th of March 2001 the Freenet Project started taking donations, and within a week we had collected over $1000.

11. More sophisticated approaches: Fairshare

Of course some people ridicule this idea on the basis (I assume) that nobody would ever pay for something unless forced to do so (despite significant evidence to the contrary). While I disagree with their rather depressing outlook on humanity, there are more sophisticated mechanisms which do appeal to people’s self-interest, such as “Fairshare”, where people can buy in to artists much as a venture capitalist will buy into an idea they like, and if that artist is successful they will be rewarded in proportion to their original contribution. This has the nice effect of encouraging people to give more money to obscure artists who they believe have potential. If their investment doesn’t pay-off, then they still have the satisfaction that they contributed to an artist whose work they enjoy.
