<br><br>It is very common to have a dental emergency -- a fractured tooth, an abscess, or severe pain when chewing. Over-the-counter pain medication is just masking the problem. Seeing an emergency dentist is critical to getting the source of the problem diagnosed and corrected as soon as possible.<br><br>Here are some common dental emergencies:<br>Toothache: The most common dental emergency. This generally means a badly decayed tooth. As the pain affects the tooth's nerve, treatment involves gently removing any debris lodged in the cavity being careful not to poke deep as this will cause severe pain if the nerve is touched. Next rinse vigorously with warm water. Then soak a small piece of cotton in oil of cloves and insert it in the cavity. This will give temporary relief until a dentist can be reached.<br><br>At times the pain may have a more obscure location such as decay under an old filling. As this can be only corrected by a dentist there are two things you can do to help the pain. Administer a pain pill (aspirin or some other analgesic) internally or dissolve a tablet in a half glass (4 oz) of warm water holding it in the mouth for several minutes before spitting it out. DO NOT PLACE A WHOLE TABLET OR ANY PART OF IT IN THE TOOTH OR AGAINST THE SOFT GUM TISSUE AS IT WILL RESULT IN A NASTY BURN.<br><br>Swollen Jaw: This may be caused by several conditions the most probable being an abscessed tooth. In any case the treatment should be to reduce pain and swelling. An ice pack held on the outside of the jaw, (ten minutes on and ten minutes off) will take care of both. If this does not control the pain, an analgesic tablet can be given every four hours.<br><br>Other Oral Injuries: Broken teeth, cut lips, bitten tongue or lips if severe means a trip to a dentist as soon as possible. In the mean time rinse the mouth with warm water and place cold compression the face opposite the injury. If there is a lot of bleeding, apply direct pressure to the bleeding area. If bleeding does not stop get patient to the emergency room of a hospital as stitches may be necessary.<br><br>Prolonged Bleeding Following Extraction: Place a gauze pad or better still a moistened tea bag over the socket and have the patient bite down gently on it for 30 to 45 minutes. The tannic acid in the tea seeps into the tissues and often helps stop the bleeding. If bleeding continues after two hours, call the dentist or take patient to the emergency room of the nearest hospital.<br><br>Broken Jaw: If you suspect the patient's jaw is broken, bring the upper and lower teeth together. Put a necktie, handkerchief or towel under the chin, tying it over the head to immobilize the jaw until you can get the patient to a dentist or the emergency room of a hospital.<br><br>Painful Erupting Tooth: In young children teething pain can come from a loose baby tooth or from an erupting permanent tooth. Some relief can be given by crushing a little ice and wrapping it in gauze or a clean piece of cloth and putting it directly on the tooth or gum tissue where it hurts. The numbing effect of the cold, along with an appropriate dose of aspirin, usually provides temporary relief.<br><br>In young adults, an erupting 3rd molar (Wisdom tooth), especially if it is impacted, can cause the jaw to swell and be quite painful. Often the gum around the tooth will show signs of infection. Temporary relief can be had by giving aspirin or some other painkiller and by dissolving an aspirin in half a glass of warm water and holding this solution in the mouth over the sore gum. AGAIN DO NOT PLACE A TABLET DIRECTLY OVER THE GUM OR CHEEK OR USE THE ASPIRIN SOLUTION ANY STRONGER THAN RECOMMENDED TO PREVENT BURNING THE TISSUE. The swelling of the jaw can be reduced by using an ice pack on the outside of the face at intervals of ten minutes on and ten minutes off.<br><br>Here's more about [http://www.youtube.com/watch?v=90z1mmiwNS8 Dentists in DC] stop by the web page.

'''Freenet''' is a [[peer-to-peer]] platform for [[censorship]]-resistant communication. It uses a decentralized [[distributed data store]] to store information, and has a suite of [[free software]] for working with this data store. Both Freenet and some of its associated tools were originally designed by [[Ian Clarke (computer scientist)|Ian Clarke]],<ref name="time">{{cite news|url=http://www.time.com/time/magazine/article/0,9171,997286,00.html|title=The Infoanarchist|last=Cohen|first=Adam|date=26 June 2000|work=[[TIME]]|accessdate=18 December 2011}}</ref><ref name="guardian">{{cite news|url=http://www.guardian.co.uk/technology/2009/nov/26/dark-side-internet-freenet|title=The dark side of the internet|last=Beckett|first=Andy|date=26 November 2009|work=[[The Guardian]]|accessdate=26 November 2009}}</ref> who defines Freenet's goal as providing [[freedom of speech]] with strong anonymity protection.
 
Freenet works by storing small encrypted snippets of content distributed on the computers of its users and connecting only through intermediate computers which pass on requests for content and sending them back without knowing the contents of the full file, similar to how [[Router (computing)|routers]] on the Internet route [[Network packet|packets]] without knowing anything about files—except with caching, a layer of strong encryption, and without reliance on [[Centralized computing|centralized structures]]. This allows users to publish anonymously or retrieve various kinds of information. Freenet has been under continuous development since 2000.
 
Since Version 0.7 (2008), it offers two modes of operation: a [[Darknet (file sharing)|darknet]] mode in which it connects only to friends, and an opennet-mode in which it connects to any other Freenet user. Both modes can be used together. When a user changes to pure darknet operation, Freenet becomes very difficult to detect from the outside. The [[transport layer]] created for the darknet mode allows communication over restricted routes as commonly found in [[mesh networking|mesh networks]], as long as these connections follow a [[Small-world network|small-world]] structure.
 
The distributed datastore of Freenet is used by many third-party programs and plugins to provide [[microblogging]] and media sharing,<ref name="sone">{{cite web | url=http://new-wiki.freenetproject.org/Sone|title=Sone, a pseudonymous microblogging plugin for Freenet}}{{self-published inline|date=August 2013}}</ref> anonymous, decentralised version tracking,<ref name="infocalypse">{{cite web | url=http://mercurial.selenic.com/wiki/Infocalypse | title=Infoclypse: A Mercurial plugin for decentral, anonymous versiontracking and code-sharing over freenet}}{{self-published inline|date=August 2013}}</ref> blogging,<ref name="floghelper">{{cite web | url=https://github.com/freenet/plugin-FlogHelper-staging|title=Flog Helper: Easy Blogging over Freenet}}</ref> a generic [[web of trust]] for decentralized [[Anti-spam techniques|spam resistance]],<ref name="weboftrust">{{cite web|url=http://new-wiki.freenetproject.org/WoT|title=Web Of Trust: A freenet plugin for pseudonymous, decentral spam resistance}}{{self-published inline|date=August 2013}}</ref> Shoeshop for using Freenet over [[Sneakernet]],<ref name="shoeshop">{{cite web| title=Freenet over Sneakernet.

Freenet has always been free software, but for most of its history it required users to install [[proprietary software|proprietary]] Java software.  In 2011, this problem was solved and Freenet can now also work with the free [[OpenJDK]] Java system.
 
==Features and user interface of the Freenet==
Freenet is different from most other peer-to-peer applications, both in how users interact with it and in the security it offers.  It separates the underlying network structure and protocol from how users interact with the network; as a result, there are a variety of ways to access content on the Freenet network.  The simplest is via FProxy, which is integrated with the node software and provides a web interface to content on the network.  Using FProxy, a user can browse freesites (websites that use normal [[HTML]] and related tools, but whose content is stored within Freenet rather than on a traditional web server).  The web interface is also used for most configuration and node management tasks. Through the use of separate applications or plugins loaded into the node software, users can interact with the network in other ways, such as forums similar to web forums or Usenet or interfaces more similar to traditional p2p "filesharing" interfaces.
 
While Freenet provides an [[HTTP]] interface for browsing freesites, it is not a [[Proxy server|proxy]] for the [[World Wide Web]]; Freenet can only be used to access content that has been previously inserted into the Freenet network.  In this way, it is more similar to [[Tor (anonymity network)#Hidden services|Tor's hidden services]] than to anonymous proxy software like [[Tor (anonymity network)|Tor's proxy]].
 
Freenet's focus lies on [[Freedom of speech|Free speech]] and anonymity. Because of that, Freenet acts different at certain points that are (direct or indirect) related to the anonymity part. Freenet attempts to protect the anonymity of both people inserting data into the network (uploading) and those retrieving data from the network (downloading).  Unlike file sharing systems, there is no need for the uploader to remain on the network after uploading a file or group of files.  Instead, during the upload process, the files are broken into chunks and stored on a variety of other computers on the network. When downloading, those chunks are found and reassembled.  Every node on the Freenet network contributes storage space to hold files, and bandwidth that it uses to route requests from its peers.
 
As a direct result of the anonymity requirements, the node requesting a datum does not normally connect directly to the node that has it; instead, the datum is routed across several intermediaries, none of which know which node requested the datum or which one had it.  As a result, the total bandwidth required by the network to transfer a file is higher than in other systems, which can result in slower transfers, especially  for unpopular content.
 
Since Version 0.7, Freenet offers two different levels of security: Opennet and Darknet. With Opennet, users connect to arbitrary other users. With Darknet, users connect only to "friends" with whom they previously exchanged [[Public-key cryptography|Public Keys]], named node-references. Both modes can be used together.
 
==Content==
Freenet's founders argue that true [[freedom of speech]] comes only with true anonymity, and that the beneficial uses of Freenet outweigh its negative uses.<ref name="philosophy">[https://freenetproject.org/philosophy.html The Philosophy behind Freenet]</ref> Their view is that free speech, in itself, is not in contradiction with any other consideration — the information is not the crime.  Freenet attempts to remove the possibility of any group imposing their beliefs or values on any data.  Although many states censor communications to different extents, they all share one commonality in that a body must decide what information to censor and what information to allow.  What may be acceptable to one group of people may be considered offensive or even dangerous to another.  In essence, the purpose of Freenet is that nobody is allowed to decide what is acceptable.
 
Reports of Freenet's use in authoritarian nations is difficult to track due to the very nature of Freenet's goals. One group, Freenet-China, used to translate the Freenet software to Chinese and distribute it within China on CD and floppy disk until mid-2003.<ref>http://freenet-china.org/{{full|date=August 2013}}{{failed verification|date=August 2013}}</ref>
 
==Technical design==
{{See also|Cryptography}}
The Freenet [[file sharing]] network stores documents and allows them to be retrieved later by an associated key, as is now possible with protocols such as [[HyperText Transfer Protocol|HTTP]]. The network is designed to be highly survivable, with all internal processes completely anonymized and decentralized across the network. The system has no central servers and is not subject to the control of any one individual or organization, including the designers of Freenet. Information stored on Freenet is distributed around the network and stored on several different nodes. Encryption of data and relaying of requests makes it difficult to determine who inserted content into Freenet, who requested that content, or where the content was stored. This protects the anonymity of participants, and also makes it very difficult to censor specific content.  Content is stored encrypted, making it difficult for even the operator of a node to determine what is stored on that node.  This provides [[plausible deniability]], and in combination with the request relaying means that [[Safe harbor (law)|safe harbor]] laws that protect service providers may also protect Freenet node operators.<ref>{{cite web|url=https://emu.freenetproject.org/pipermail/chat/2009-February/001872.html|last=Toseland|first=Matthew |title=Does Freenet qualify for DMCA Safe Harbor? |deadurl=no |accessdate=27 January 2013}}{{self-published inline|date=August 2013}}</ref>
 
===Distributed storage and caching of data===
Unlike other [[P2P network]]s, Freenet not only transmits data between nodes but actually stores them, working as a huge distributed cache.
To achieve this, each node allocates some amount of disk space to store data; this is configurable by the node operator, but is typically several GB (or more).
 
Files on Freenet are typically split into multiple small blocks, with additional blocks added to provide [[Forward error correction|redundancy]].  Each block is handled independently, meaning that a single file may have parts stored on many different nodes.
 
Information flow in Freenet is different from networks like [[eMule]] or [[BitTorrent (protocol)|BitTorrent]]:
# A user wishing to share a file or update a freesite "inserts" the file "to the network"
# After "insertion" is finished, the publishing node is free to shut down, because the file is stored in the network. It will remain available for other users whether or not the original publishing node is online. No single node is responsible for the content; instead, it is replicated to many different nodes.
 
Two advantages of this design are high reliability and anonymity. Information remains available even if the publisher node goes offline, and is anonymously spread over many hosting nodes as encrypted blocks, not entire files.
 
The key disadvantage of the storage method is that no one node is responsible for any chunk of data. If a piece of data is not retrieved for some time and a node keeps getting new data, it will drop the old data sometime when its allocated disk space is fully used. In this way Freenet tends to 'forget' data which is not retrieved regularly (see also [[Freenet#Effect|Effect]]).
 
While users can insert data into the network, there is no way to delete data. Due to Freenet's anonymous nature the original publishing node or owner of any piece of data is unknown. The only way data can be removed is if users don't request it.
 
===Network===
The network consists of multiple nodes, which depends on the size of the network. These nodes pass messages among themselves. Typically, a host computer on the network runs the software that acts as a node, and it connects to other hosts running that same software to form a large distributed network of peer nodes. Some nodes are end user nodes, from which documents are requested and presented to human users. Other nodes serve only to route data. All nodes communicate with each other identically — there are no dedicated "clients" or "servers". It is not possible for a node to rate another node except by its capacity to insert and fetch data associated with a key. This is unlike most other P2P networks where node administrators can employ a ratio system, where users have to share a certain amount of content before they can download.
 
Freenet may also be considered a [[small world network]].
 
The Freenet protocol is intended to be used on a network of complex topology, such as the Internet ([[Internet Protocol]]). Each node knows only about some number of other nodes that it can reach directly (its conceptual "neighbors"), but any node can be a neighbor to any other; no hierarchy or other structure is intended. Each message is routed through the network by passing from neighbor to neighbor until it reaches its destination. As each node passes a message to a neighbor, it does not know or care whether the neighbor will forward the message to another node, or is the final destination or original source of the message. This is intended to protect the anonymity of users and publishers.
 
Each node maintains a data store containing documents associated with keys, and a routing table associating nodes with records of their performance in retrieving different keys.
 
===Protocol===
[[File:Freenet Request Sequence ZP.svg|thumb|A typical request sequence. The request moves through the network from node to node, backing out of a dead-end (step 3) and a loop (step 7) before locating the desired file.]]
 
The Freenet protocol uses a [[key-based routing]] protocol, similar to [[distributed hash table]]s. The routing algorithm changed significantly in version 0.7. Prior to version 0.7, Freenet used a [[heuristic routing]] algorithm where each node had no fixed location, and routing was based on which node had served a key closest to the key being fetched (in version 0.3) or which is estimated to serve it faster (in version 0.5).  In either case, new connections were sometimes added to downstream nodes (i.e. the node that answered the request) when requests succeeded, and old nodes were discarded in least recently used order (or something close to it). Oskar Sandberg's research (during the development of version 0.7) shows that this "path folding" is critical, and that a very simple routing algorithm will suffice provided there is path folding.{{citation needed|date=July 2013}}
 
The disadvantage of this is that it is very easy for an attacker to find Freenet nodes, and connect to them, because every node is continually attempting to find new connections. In version 0.7, Freenet supports both 'Opennet' (similar to the old algorithms, but simpler), and "[[Darknet (file sharing)|Darknet]]" (all node connections are set up manually, so only your friends know your node's IP address). Darknet is less convenient, but much more secure against a distant attacker.{{citation needed|date=July 2013}}
 
This change required major changes in the routing algorithm. Every node has a location, which is a number between 0 and 1. When a key is requested, first the node checks the local data store. If it's not found, the key's hash is turned into another number in the same range, and the request is routed to the node whose location is closest to the key. This goes on until some number of hops is exceeded, there are no more nodes to search, or the data is found. If the data is found, it is cached on each node along the path. So there is no one source node for a key, and attempting to find where it is currently stored will result in it being cached more widely. Essentially the same process is used to insert a document into the network: the data is routed according to the key until it runs out of hops, and if no existing document is found with the same key, it is stored on each node. If older data is found, the older data is propagated and returned to the originator, and the insert "collides".{{citation needed|date=July 2013}}
 
But this only works if the locations are clustered in the right way. Freenet assumes that the Darknet (a subset of the global social network) is a [[small-world network]], and nodes constantly attempt to swap locations (using the [[Metropolis–Hastings algorithm]]) in order to minimize their distance to their neighbors. If the network actually is a small-world network, Freenet should find data reasonably quickly; ideally on the order of [[Big O notation|<math>O\left\{\left[log\left(n\right)\right]^2\right\}</math>]] hops. However, it does not guarantee that data will be found at all.{{citation needed|date=July 2013}}
 
Eventually, either the document is found or the hop limit is exceeded. The terminal node sends a reply that makes its way back to the originator along the route specified by the intermediate nodes' records of pending requests. The intermediate nodes may choose to cache the document along the way. Besides saving bandwidth, this also makes documents harder to censor as there is no one "source node."{{citation needed|date=July 2013}}
 
===Effect===
[[File:Freenet datastore specialisation.ani.gif|thumb|450px|right|The effect of the node specialising on the particular location.]]
Initially, the locations are distributed randomly (whether on Opennet or Darknet). This means that routing of requests is essentially random. But since different nodes have different randomness, they will disagree about where to send a request, given a key. So the data in a newly started Freenet will be distributed somewhat randomly.{{citation needed|date=July 2013}}
 
As location swapping (on Darknet) and path folding (on Opennet) progress, nodes which are close to one another will increasingly have close locations, and nodes which are far away will have distant locations. Data with similar keys will be stored on the same node.{{citation needed|date=July 2013}}
 
The result is that the network will self-organize into a distributed, clustered structure where nodes tend to hold data items that are close together in key space. There will probably be multiple such clusters throughout the network, any given document being replicated numerous times, depending on how much it is used. This is a kind of "[[spontaneous symmetry breaking]]", in which an initially symmetric state (all nodes being the same, with random initial keys for each other) leads to a highly asymmetric situation, with nodes coming to specialize in data that has closely related keys.{{citation needed|date=July 2013}}
 
There are forces which tend to cause clustering (shared closeness data spreads throughout the network), and forces that tend to break up clusters (local caching of commonly used data). These forces will be different depending on how often data is used, so that seldom-used data will tend to be on just a few nodes which specialize in providing that data, and frequently used items will be spread widely throughout the network. This automatic mirroring counteracts the times when [[web traffic]] becomes overloaded, and due to a mature network's intelligent routing, a network of size ''n'' should only require log(''n'') time to retrieve a document on average.{{citation needed|date=July 2013}}
 
===Keys===
Keys are [[hash function|hashes]]: there is no notion of [[semantic closeness]] when speaking of key closeness. Therefore there will be no correlation between key closeness and similar popularity of data as there might be if keys did exhibit some semantic meaning, thus avoiding bottlenecks caused by popular subjects.{{citation needed|date=July 2013}}
 
There are two main varieties of keys in use on Freenet, the [https://wiki.freenetproject.org/FreenetCHKPages Content Hash Key] (CHK) and the [https://wiki.freenetproject.org/FreenetSSKPages Signed Subspace Key] (SSK).
 
A CHK is a [[SHA-256]] hash of a document (after encryption, which itself depends on the hash of the plaintext) and thus a node can check that the document returned is correct by hashing it and checking the digest against the key. This key contains the meat of the data on Freenet. It carries all the binary data building blocks for the content to be delivered to the client for reassembly and decryption. The CHK is unique by nature and provides tamperproof content. A hostile node altering the data under a CHK will immediately be detected by the next node or the client. CHKs also reduce the redundancy of data since the same data will have the same CHK.{{citation needed|date=July 2013}}
 
SSKs are based on [[public-key cryptography]]. Currently Freenet uses the [[Digital Signature Algorithm|DSA]] algorithm. Documents inserted under SSKs are signed by the inserter, and this signature can be verified by every node to ensure that the data is not tampered with. SSKs can be used to establish a verifiable [[pseudonymity|pseudonymous]] identity on Freenet, and allow for documents to be updated securely by the person who inserted them. A subtype of the SSK is the Keyword Signed Key, or KSK, in which the key pair is generated in a standard way from a simple human-readable string. Inserting a document using a KSK allows the document to be retrieved and decrypted if and only if the requester knows the human-readable string; this allows for more convenient (but less secure) [[Uniform Resource Identifier|URIs]] for users to refer to.{{citation needed|date=July 2013}}
 
==Scalability==
A [[Computer networking|network]] is said to be scalable if its performance does not deteriorate even if the network is very large. The scalability of Freenet is being evaluated, but similar architectures have been shown to scale logarithmically.<ref>{{cite book |doi=10.1145/335305.335325 |chapter=The Small-World Phenomenon: An Algorithmic Perspective |title=Proceedings of the thirty-second annual ACM symposium on Theory of computing |year=2000 |last1=Kleinberg |first1=Jon |isbn=978-1-58113-184-0 |pages=163–70 |chapterurl=http://www.cs.cornell.edu/home/kleinber/swn.pdf}}</ref> This work indicates that Freenet can find data in <math>O(\log^2 n)</math> hops on a small-world network (which includes both opennet and darknet style Freenet networks), when ignoring the caching which could improve the scalability for popular content. However, this scalability is difficult to test without a very large network. Furthermore, the security features inherent to Freenet make detailed performance analysis (including things as simple as determining the size of the network) difficult to do accurately. As of now, the scalability of freenet has yet to be tested.
 
==Darknet versus Opennet==
As of version 0.7, Freenet supports both "[[Darknet (file sharing)|darknet]]" and "[[opennet]]" connections.  Opennet connections are made automatically by nodes with opennet enabled, while darknet connections are manually established between users that know and trust each other. Opennet connections are easy to use, but darknet connections are more secure against attackers on the network, and can make it difficult for an attacker (such as an oppressive government) to even determine that a user is running Freenet in the first place.  For users in such places, the darknet option may be a requirement in order to avoid prosecution by such a government.{{citation needed|date=July 2013}}
 
The core innovation in Freenet 0.7 is to allow a globally scalable darknet, capable (at least in theory) of supporting millions of users.  Previous darknets, such as [[WASTE]], have been limited to relatively small disconnected networks.  This scalability is made possible by the fact that human relationships tend to form [[small-world network]]s, a property that can be exploited to find short paths between any two people. The work is based on a speech given at [[DEF CON (convention)|DEF CON 13]] by [[Ian Clarke (computer scientist)|Ian Clarke]] and Swedish mathematician [[Oskar Sandberg]].  Furthermore, the routing algorithm is capable of routing over a mixture of opennet and darknet connections, allowing people who have only a few friends using the network to get the performance from having sufficient connections while still receiving some of the security benefits of darknet connections.  This also means that small darknets where some users also have opennet connections are fully integrated into the whole Freenet network, allowing all users access to all content, whether they run opennet, darknet, or a hybrid of the two.{{citation needed|date=July 2013}}
 
==Post-2008 development==
[[File:freenet darknet.png|thumb|The Freenet 0.7 darknet peers list.]]
 
Freenet 0.7, released on 8 May 2008, is a major re-write incorporating a number of fundamental changes. The most fundamental change is support for [[Darknet (file sharing)|darknet]] operation, described above. Other modifications include switching from [[Transmission Control Protocol|TCP]] to [[User Datagram Protocol|UDP]], which allows [[UDP hole punching]] along with faster transmission of messages between peers in the network.{{citation needed|date=July 2013}}
 
Freenet 0.7.5, released on 12 June 2009, offers a variety of improvements over 0.7. These include reduced memory usage, faster insert and retrieval of content, significant improvements to the FProxy web interface used for browsing freesites, and a large number of smaller bugfixes, performance enhancements, and usability improvements.  Version 0.7.5 also shipped with a new version of the Windows installer.{{citation needed|date=July 2013}}
 
As of build 1226, released on 30 July 2009, features that have been written and will be included in version 0.8 include significant security improvements against both attackers acting on the network and physical seizure of the computer running the node.  Like version 0.7.5, version 0.8 will be based on the 0.7 code.  Other features likely to be included in version 0.8 are continued improvements to both performance and security, as well as usability enhancements and bug fixes.{{citation needed|date=July 2013}}
 
As of build 1397, released on 17 August 2011, there have been large scale experiment with new load management (NLM) to increase throughput and reduce the impact of hostile nodes on the network. As of build 1405, work is still ongoing to adapt freenet internals for default usage of NLM.{{citation needed|date=July 2013}}
 
== Tools and applications ==
[[File:frost screenshot.png|thumb|Screenshot of Frost running on [[Microsoft Windows]]]]
 
Unlike many other P2P applications Freenet does not provide comprehensive functionality itself. Freenet is modular and features an [[Application programming interface|API]] called Freenet Client Protocol (FCP) for other programs to use to implement services such as [[message boards]], [[file sharing]], or [[online chat]].{{citation needed|date=July 2013}}
 
===Forums===

It uses a decentralized distributed data store to store information, and has a suite of free software for working with this data store. Both Freenet and some of its associated tools were originally designed by Ian Clarke,[1][2] who defines Freenet's goal as providing freedom of speech with strong anonymity protection.

Freenet works by storing small encrypted snippets of content distributed on the computers of its users and connecting only through intermediate computers which pass on requests for content and sending them back without knowing the contents of the full file, similar to how routers on the Internet route packets without knowing anything about files—except with caching, a layer of strong encryption, and without reliance on centralized structures. This allows users to publish anonymously or retrieve various kinds of information. Freenet has been under continuous development since 2000.

Since Version 0.7 (2008), it offers two modes of operation: a darknet mode in which it connects only to friends, and an opennet-mode in which it connects to any other Freenet user. Both modes can be used together. When a user changes to pure darknet operation, Freenet becomes very difficult to detect from the outside. The transport layer created for the darknet mode allows communication over restricted routes as commonly found in mesh networks, as long as these connections follow a small-world structure.

The distributed datastore of Freenet is used by many third-party programs and plugins to provide microblogging and media sharing,[3] anonymous, decentralised version tracking,[4] blogging,[5] a generic web of trust for decentralized spam resistance,[6] Shoeshop for using Freenet over Sneakernet,[7] and many more.

Freenet has always been free software, but for most of its history it required users to install proprietary Java software. In 2011, this problem was solved and Freenet can now also work with the free OpenJDK Java system.

Features and user interface of the Freenet

Freenet is different from most other peer-to-peer applications, both in how users interact with it and in the security it offers. It separates the underlying network structure and protocol from how users interact with the network; as a result, there are a variety of ways to access content on the Freenet network. The simplest is via FProxy, which is integrated with the node software and provides a web interface to content on the network. Using FProxy, a user can browse freesites (websites that use normal HTML and related tools, but whose content is stored within Freenet rather than on a traditional web server). The web interface is also used for most configuration and node management tasks. Through the use of separate applications or plugins loaded into the node software, users can interact with the network in other ways, such as forums similar to web forums or Usenet or interfaces more similar to traditional p2p "filesharing" interfaces.

While Freenet provides an HTTP interface for browsing freesites, it is not a proxy for the World Wide Web; Freenet can only be used to access content that has been previously inserted into the Freenet network. In this way, it is more similar to Tor's hidden services than to anonymous proxy software like Tor's proxy.

Freenet's focus lies on Free speech and anonymity. Because of that, Freenet acts different at certain points that are (direct or indirect) related to the anonymity part. Freenet attempts to protect the anonymity of both people inserting data into the network (uploading) and those retrieving data from the network (downloading). Unlike file sharing systems, there is no need for the uploader to remain on the network after uploading a file or group of files. Instead, during the upload process, the files are broken into chunks and stored on a variety of other computers on the network. When downloading, those chunks are found and reassembled. Every node on the Freenet network contributes storage space to hold files, and bandwidth that it uses to route requests from its peers.

As a direct result of the anonymity requirements, the node requesting a datum does not normally connect directly to the node that has it; instead, the datum is routed across several intermediaries, none of which know which node requested the datum or which one had it. As a result, the total bandwidth required by the network to transfer a file is higher than in other systems, which can result in slower transfers, especially for unpopular content.

Since Version 0.7, Freenet offers two different levels of security: Opennet and Darknet. With Opennet, users connect to arbitrary other users. With Darknet, users connect only to "friends" with whom they previously exchanged Public Keys, named node-references. Both modes can be used together.

Content

Freenet's founders argue that true freedom of speech comes only with true anonymity, and that the beneficial uses of Freenet outweigh its negative uses.[8] Their view is that free speech, in itself, is not in contradiction with any other consideration — the information is not the crime. Freenet attempts to remove the possibility of any group imposing their beliefs or values on any data. Although many states censor communications to different extents, they all share one commonality in that a body must decide what information to censor and what information to allow. What may be acceptable to one group of people may be considered offensive or even dangerous to another. In essence, the purpose of Freenet is that nobody is allowed to decide what is acceptable.

Reports of Freenet's use in authoritarian nations is difficult to track due to the very nature of Freenet's goals. One group, Freenet-China, used to translate the Freenet software to Chinese and distribute it within China on CD and floppy disk until mid-2003.[9]

The Hexacube is offering new ec launch singapore business property for sale Singapore investors want to contemplate. Residents of the realm will likely appreciate that they'll customize the business area that they wish to purchase as properly. This venture represents one of the crucial expansive buildings offered in Singapore up to now. Many investors will possible want to try how they will customise the property that they do determine to buy by means of here. This location has offered folks the prospect that they should understand extra about how this course of can work as well.

Singapore has been beckoning to traders ever since the value of properties in Singapore started sky rocketing just a few years again. Many businesses have their places of work in Singapore and prefer to own their own workplace area within the country once they decide to have a everlasting office. Rentals in Singapore in the corporate sector can make sense for some time until a business has discovered a agency footing. Finding Commercial Property Singapore takes a variety of time and effort but might be very rewarding in the long term.

In 12 months 2013, c ommercial retails, shoebox residences and mass market properties continued to be the celebrities of the property market. Models are snapped up in report time and at document breaking prices. Builders are having fun with overwhelming demand and patrons need more. We feel that these segments of the property market are booming is a repercussion of the property cooling measures no.6 and no. 7. With additional buyer's stamp responsibility imposed on residential properties, buyers change their focus to commercial and industrial properties. I imagine every property purchasers need their property funding to understand in value. The Freenet file sharing network stores documents and allows them to be retrieved later by an associated key, as is now possible with protocols such as HTTP. The network is designed to be highly survivable, with all internal processes completely anonymized and decentralized across the network. The system has no central servers and is not subject to the control of any one individual or organization, including the designers of Freenet. Information stored on Freenet is distributed around the network and stored on several different nodes. Encryption of data and relaying of requests makes it difficult to determine who inserted content into Freenet, who requested that content, or where the content was stored. This protects the anonymity of participants, and also makes it very difficult to censor specific content. Content is stored encrypted, making it difficult for even the operator of a node to determine what is stored on that node. This provides plausible deniability, and in combination with the request relaying means that safe harbor laws that protect service providers may also protect Freenet node operators.[10]

Distributed storage and caching of data

Unlike other P2P networks, Freenet not only transmits data between nodes but actually stores them, working as a huge distributed cache. To achieve this, each node allocates some amount of disk space to store data; this is configurable by the node operator, but is typically several GB (or more).

Files on Freenet are typically split into multiple small blocks, with additional blocks added to provide redundancy. Each block is handled independently, meaning that a single file may have parts stored on many different nodes.

Information flow in Freenet is different from networks like eMule or BitTorrent:

  1. A user wishing to share a file or update a freesite "inserts" the file "to the network"
  2. After "insertion" is finished, the publishing node is free to shut down, because the file is stored in the network. It will remain available for other users whether or not the original publishing node is online. No single node is responsible for the content; instead, it is replicated to many different nodes.

Two advantages of this design are high reliability and anonymity. Information remains available even if the publisher node goes offline, and is anonymously spread over many hosting nodes as encrypted blocks, not entire files.

The key disadvantage of the storage method is that no one node is responsible for any chunk of data. If a piece of data is not retrieved for some time and a node keeps getting new data, it will drop the old data sometime when its allocated disk space is fully used. In this way Freenet tends to 'forget' data which is not retrieved regularly (see also Effect).

While users can insert data into the network, there is no way to delete data. Due to Freenet's anonymous nature the original publishing node or owner of any piece of data is unknown. The only way data can be removed is if users don't request it.

Network

The network consists of multiple nodes, which depends on the size of the network. These nodes pass messages among themselves. Typically, a host computer on the network runs the software that acts as a node, and it connects to other hosts running that same software to form a large distributed network of peer nodes. Some nodes are end user nodes, from which documents are requested and presented to human users. Other nodes serve only to route data. All nodes communicate with each other identically — there are no dedicated "clients" or "servers". It is not possible for a node to rate another node except by its capacity to insert and fetch data associated with a key. This is unlike most other P2P networks where node administrators can employ a ratio system, where users have to share a certain amount of content before they can download.

Freenet may also be considered a small world network.

The Freenet protocol is intended to be used on a network of complex topology, such as the Internet (Internet Protocol). Each node knows only about some number of other nodes that it can reach directly (its conceptual "neighbors"), but any node can be a neighbor to any other; no hierarchy or other structure is intended. Each message is routed through the network by passing from neighbor to neighbor until it reaches its destination. As each node passes a message to a neighbor, it does not know or care whether the neighbor will forward the message to another node, or is the final destination or original source of the message. This is intended to protect the anonymity of users and publishers.

Each node maintains a data store containing documents associated with keys, and a routing table associating nodes with records of their performance in retrieving different keys.

Protocol

A typical request sequence. The request moves through the network from node to node, backing out of a dead-end (step 3) and a loop (step 7) before locating the desired file.

The Freenet protocol uses a key-based routing protocol, similar to distributed hash tables. The routing algorithm changed significantly in version 0.7. Prior to version 0.7, Freenet used a heuristic routing algorithm where each node had no fixed location, and routing was based on which node had served a key closest to the key being fetched (in version 0.3) or which is estimated to serve it faster (in version 0.5). In either case, new connections were sometimes added to downstream nodes (i.e. the node that answered the request) when requests succeeded, and old nodes were discarded in least recently used order (or something close to it). Oskar Sandberg's research (during the development of version 0.7) shows that this "path folding" is critical, and that a very simple routing algorithm will suffice provided there is path folding.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

The disadvantage of this is that it is very easy for an attacker to find Freenet nodes, and connect to them, because every node is continually attempting to find new connections. In version 0.7, Freenet supports both 'Opennet' (similar to the old algorithms, but simpler), and "Darknet" (all node connections are set up manually, so only your friends know your node's IP address). Darknet is less convenient, but much more secure against a distant attacker.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

This change required major changes in the routing algorithm. Every node has a location, which is a number between 0 and 1. When a key is requested, first the node checks the local data store. If it's not found, the key's hash is turned into another number in the same range, and the request is routed to the node whose location is closest to the key. This goes on until some number of hops is exceeded, there are no more nodes to search, or the data is found. If the data is found, it is cached on each node along the path. So there is no one source node for a key, and attempting to find where it is currently stored will result in it being cached more widely. Essentially the same process is used to insert a document into the network: the data is routed according to the key until it runs out of hops, and if no existing document is found with the same key, it is stored on each node. If older data is found, the older data is propagated and returned to the originator, and the insert "collides".Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

But this only works if the locations are clustered in the right way. Freenet assumes that the Darknet (a subset of the global social network) is a small-world network, and nodes constantly attempt to swap locations (using the Metropolis–Hastings algorithm) in order to minimize their distance to their neighbors. If the network actually is a small-world network, Freenet should find data reasonably quickly; ideally on the order of hops. However, it does not guarantee that data will be found at all.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

Eventually, either the document is found or the hop limit is exceeded. The terminal node sends a reply that makes its way back to the originator along the route specified by the intermediate nodes' records of pending requests. The intermediate nodes may choose to cache the document along the way. Besides saving bandwidth, this also makes documents harder to censor as there is no one "source node."Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

Effect

The effect of the node specialising on the particular location.

Initially, the locations are distributed randomly (whether on Opennet or Darknet). This means that routing of requests is essentially random. But since different nodes have different randomness, they will disagree about where to send a request, given a key. So the data in a newly started Freenet will be distributed somewhat randomly.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

As location swapping (on Darknet) and path folding (on Opennet) progress, nodes which are close to one another will increasingly have close locations, and nodes which are far away will have distant locations. Data with similar keys will be stored on the same node.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

The result is that the network will self-organize into a distributed, clustered structure where nodes tend to hold data items that are close together in key space. There will probably be multiple such clusters throughout the network, any given document being replicated numerous times, depending on how much it is used. This is a kind of "spontaneous symmetry breaking", in which an initially symmetric state (all nodes being the same, with random initial keys for each other) leads to a highly asymmetric situation, with nodes coming to specialize in data that has closely related keys.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

There are forces which tend to cause clustering (shared closeness data spreads throughout the network), and forces that tend to break up clusters (local caching of commonly used data). These forces will be different depending on how often data is used, so that seldom-used data will tend to be on just a few nodes which specialize in providing that data, and frequently used items will be spread widely throughout the network. This automatic mirroring counteracts the times when web traffic becomes overloaded, and due to a mature network's intelligent routing, a network of size n should only require log(n) time to retrieve a document on average.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

Keys

Keys are hashes: there is no notion of semantic closeness when speaking of key closeness. Therefore there will be no correlation between key closeness and similar popularity of data as there might be if keys did exhibit some semantic meaning, thus avoiding bottlenecks caused by popular subjects.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

There are two main varieties of keys in use on Freenet, the Content Hash Key (CHK) and the Signed Subspace Key (SSK).

A CHK is a SHA-256 hash of a document (after encryption, which itself depends on the hash of the plaintext) and thus a node can check that the document returned is correct by hashing it and checking the digest against the key. This key contains the meat of the data on Freenet. It carries all the binary data building blocks for the content to be delivered to the client for reassembly and decryption. The CHK is unique by nature and provides tamperproof content. A hostile node altering the data under a CHK will immediately be detected by the next node or the client. CHKs also reduce the redundancy of data since the same data will have the same CHK.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

SSKs are based on public-key cryptography. Currently Freenet uses the DSA algorithm. Documents inserted under SSKs are signed by the inserter, and this signature can be verified by every node to ensure that the data is not tampered with. SSKs can be used to establish a verifiable pseudonymous identity on Freenet, and allow for documents to be updated securely by the person who inserted them. A subtype of the SSK is the Keyword Signed Key, or KSK, in which the key pair is generated in a standard way from a simple human-readable string. Inserting a document using a KSK allows the document to be retrieved and decrypted if and only if the requester knows the human-readable string; this allows for more convenient (but less secure) URIs for users to refer to.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

Scalability

A network is said to be scalable if its performance does not deteriorate even if the network is very large. The scalability of Freenet is being evaluated, but similar architectures have been shown to scale logarithmically.[11] This work indicates that Freenet can find data in hops on a small-world network (which includes both opennet and darknet style Freenet networks), when ignoring the caching which could improve the scalability for popular content. However, this scalability is difficult to test without a very large network. Furthermore, the security features inherent to Freenet make detailed performance analysis (including things as simple as determining the size of the network) difficult to do accurately. As of now, the scalability of freenet has yet to be tested.

Darknet versus Opennet

As of version 0.7, Freenet supports both "darknet" and "opennet" connections. Opennet connections are made automatically by nodes with opennet enabled, while darknet connections are manually established between users that know and trust each other. Opennet connections are easy to use, but darknet connections are more secure against attackers on the network, and can make it difficult for an attacker (such as an oppressive government) to even determine that a user is running Freenet in the first place. For users in such places, the darknet option may be a requirement in order to avoid prosecution by such a government.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

The core innovation in Freenet 0.7 is to allow a globally scalable darknet, capable (at least in theory) of supporting millions of users. Previous darknets, such as WASTE, have been limited to relatively small disconnected networks. This scalability is made possible by the fact that human relationships tend to form small-world networks, a property that can be exploited to find short paths between any two people. The work is based on a speech given at DEF CON 13 by Ian Clarke and Swedish mathematician Oskar Sandberg. Furthermore, the routing algorithm is capable of routing over a mixture of opennet and darknet connections, allowing people who have only a few friends using the network to get the performance from having sufficient connections while still receiving some of the security benefits of darknet connections. This also means that small darknets where some users also have opennet connections are fully integrated into the whole Freenet network, allowing all users access to all content, whether they run opennet, darknet, or a hybrid of the two.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble.

Post-2008 development

The Freenet 0.7 darknet peers list.

Freenet 0.7, released on 8 May 2008, is a major re-write incorporating a number of fundamental changes. The most fundamental change is support for darknet operation, described above. Other modifications include switching from TCP to UDP, which allows UDP hole punching along with faster transmission of messages between peers in the network.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

Freenet 0.7.5, released on 12 June 2009, offers a variety of improvements over 0.7. These include reduced memory usage, faster insert and retrieval of content, significant improvements to the FProxy web interface used for browsing freesites, and a large number of smaller bugfixes, performance enhancements, and usability improvements. Version 0.7.5 also shipped with a new version of the Windows installer.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

As of build 1226, released on 30 July 2009, features that have been written and will be included in version 0.8 include significant security improvements against both attackers acting on the network and physical seizure of the computer running the node. Like version 0.7.5, version 0.8 will be based on the 0.7 code. Other features likely to be included in version 0.8 are continued improvements to both performance and security, as well as usability enhancements and bug fixes.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble.

As of build 1397, released on 17 August 2011, there have been large scale experiment with new load management (NLM) to increase throughput and reduce the impact of hostile nodes on the network. As of build 1405, work is still ongoing to adapt freenet internals for default usage of NLM.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble.

Tools and applications

Screenshot of Frost running on Microsoft Windows

Unlike many other P2P applications Freenet does not provide comprehensive functionality itself. Freenet is modular and features an API called Freenet Client Protocol (FCP) for other programs to use to implement services such as message boards, file sharing, or online chat.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble.

Forums

Freenet Messaging System (FMS)
FMS was designed to address problems with Frost such as denial of service attacks and spam. Users publish trust lists, and each user only downloads messages from identities they trust and identities trusted by identities they trust. FMS is developed anonymously and can be downloaded from the FMS freesite within Freenet. It does not have an official site on the normal Internet. Is the currently most advanced messaging system for Freenet,Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park. as it features random post delay, support for many identities, and a distinction between trusting a user's posts and trusting their trust list. It is written in C++ and is a separate application from Freenet.

It uses an optimized structure to minimize the number of requests to retrieve new data, and allows supporting a repository by securely reuploading most parts of the data without requiring the owner's private keys.[12]

Libraries

FCPLib
FCPLib (Freenet Client Protocol Library) aims to be a cross-platform natively compiled set of C-based functions for storing and retrieving information to and from Freenet. FCPLib supports Windows NT/2K/XP, Debian, BSD, Solaris, and Mac OS X.
lib-pyFreenet
lib-pyFreenet exposes Freenet functionality to Python programs. Infocalypse uses it.

Freenet 0.5

When Freenet 0.5 (FCon or Freenet Classic Opennet) forked into Freenet 0.7, most users moved to Freenet 0.7.[13] Nevertheless, an active user base on Freenet 0.5 has remained. On 17 December 2011, Freenet 0.5 build 5110 was released, showing Freenet 0.5 to have a steady user base and new development;[14] however, on June 2012, the new developer declared 0.5 dead after having seen only one peer for six months.[15]

Publicity

According to CiteSeer, Ian Clarke's "Freenet: A Distributed Anonymous Information Storage and Retrieval System" was the most cited computer science paper of 2000. Freenet has also had significant publicity in the mainstream press, including articles in the New York Times, and coverage on CNN, 60 Minutes II, the BBC, and elsewhere. The mainstream press coverage has been primarily concerned with Freenet's impact on copyright enforcement, rather than Freenet's asserted goal of freedom of communication.
