These giants function primarily as spy networks for paying clients of all sorts and types, in addition to monopolizing and centralizing the Internet; a feature that was not part of the original and revolutionary goals that produced the World Wide Web. + +$Projectname is free and open source. It is designed to scale from a $35 Raspberry Pi, to top of the line AMD and Intel Xeon-powered multi-core enterprise servers. It can be used to support communication between a few individuals, or scale to many thousands and more. + +$Projectname aims to be skill and resource agnostic. It is easy to use by everyday computer users, as well as by systems administrators and developers. + +How you use it depends on how you want to use it. + +It is written in the PHP scripting language, thus making it trivial to install on any hosting platform in use today. This includes self-hosting at home, at hosting providers such as [url=http://mediatemple.com/]Media Temple[/url] and [url=http://www.dreamhost.com/]Dreamhost[/url], or on virtual and dedicated servers, offered by the likes of [url=https://www.linode.com]Linode[/url], [url=http://greenqloud.com]GreenQloud[/url] or [url=https://aws.amazon.com]Amazon AWS[/url]. + +In other words, $Projectname can run on any computing platform that comes with a web server, a MySQL-compatible database, and the PHP scripting language. + +Along the way, $Projectname offers a number of unique goodies: + +[b]Single-click user identification:[/b] meaning you can access sites on $Projectname simply by clicking on links to remote sites. Authentication just happens automagically behind the scenes. Forget about remembering multiple user names with multiple passwords when accessing different sites online. + +[b]Cloning:[/b] of online identities. Your online presence no longer has to be tied to a single server, domain name or IP address. You can clone and import your identity (or channel as we call it) to another server (or, a hub as servers are known in $Projectname). Now, should your primary hub go down, no worries, your contacts, posts[i]*[/i], and messages[i]*[/i] will automagically continue to be available and accessible under your cloned channel. [i](*: only posts and messages as from the moment you cloned your channel)[/i] + +[b]Privacy:[/b] $Projectname identities (Zot IDs) can be deleted, backed up/downloaded, and cloned. The user is in full control of their data. Should you decide to delete all your content and erase your Zot ID, all you have to do is click on a link and it's immediately deleted from the hub. No questions, no fuss. + + +[h2]Additional Resources and Links[/h2] +For more detailed, technical information about Zot, check out the following links: +[list] +[*][url=http://hubzilla.org]Hubzilla project website[/url] +[*][url=https://github.com/redmatrix/hubzilla]Hubzilla core code repository[/url] +[*][url=https://github.com/redmatrix/hubzilla-addons]Hubzilla official addons repository[/url] +[/list] + +[h2]$Projectname Governance[/h2] +Governance relates to the management of a project and particularly how this relates to conflict resolution. + +[h3]Community Governance[/h3] +The project is maintained and decisions made by the 'community'. The governance structure is still evolving. Until the structure is finalised, decisions are made in the following order: + +[ol] +[*] Lazy Consensus + +If a project proposal is made to one of the community governance forums and there are no serious objections in a "reasonable" amount of time from date of proposal (we usually provide 2-3 days for all interested parties to weigh in), no vote needs to be taken and the proposal will be considered approved. Some concerns may be raised at this time, but if these are addressed during discussion and work-arounds provided, it will still be considered approved. + + +[*] Veto + +Senior developers with a significant history of project commits may veto any decision. The decision may not proceed until the veto is removed or an alternative proposal is presented. + + +[*] Community Vote + +A decision which does not have a clear mandate or clear consensus, but is not vetoed, can be taken to a community vote. At present this is a simple popular vote in one of the applicable community forums. At this time, popular vote decides the outcome. This may change in the future if the community adopts a 'council' governance model. This document will be updated at that time with the updated governance rules. +[/ol] + +Community Voting does not always provide a pleasant outcome and can generate polarised factions in the community (hence the reason why other models are under consideration). If the proposal is 'down voted' there are still several things which can be done and the proposal re-submitted with slightly different parameters (convert to an addon, convert to an optional feature which is disabled by default, etc.). If interest in the feature is high and the vote is "close", it can generate lots of bad feelings amongst the losing voters. On such close votes, it is [b]strongly recommended[/b] that the proposer take steps to address any concerns that were raised and re-submit. + + + +[h2]Privacy Policy[/h2] + + +[h3]Summary[/h3] + + +Q: Who can see my content? + +A: By default ANYBODY on the internet, UNLESS you restrict it. $Projectname allows you to choose the privacy level you desire. Restricted content will NOT be visible to "spy networks" and advertisers. It will be protected against eavesdropping by outsiders - to the best of our ability. Hub administrators with sufficient skills and patience MAY be able to eavesdrop on some private communications but they must expend effort to do so. Privacy modes exist within $Projectname which are even resistant to eavesdropping by skilled and determined hub administrators. + +Q: Can my content be censored? + +A: $Projectname (the network) CANNOT censor your content. Server and hub administrators are subject to local laws and MAY remove objectionable content from their site/hub. Anybody MAY become a hub administrator, including you; and therefore publish content which might otherwise be censored. You still MAY be subject to local laws. + + +[h3]Definitions[/h3] + +**$Projectname** + +Otherwise referred to as "the network", $Projectname is a collection of individual computers/servers (aka **hubs**) which connect together to form a larger cooperative network. + +**hub** + +An individual computer or server connected to $Projectname. These are provided by a **hub administrator** and may be public or private, paid or free. + +**hub administrator** + +The system operator of an individual hub. + +[h3]Policies[/h3] + +**Public Information** + +Any information or anything posted by you within $Projectname MAY be public or visible to anybody on the internet. To the extent possible, $Projectname allows you to protect content and restrict who can view it. + +Your profile photo, your channel name, and the location (URL or network address) of your channel are visible to anybody on the internet and privacy controls will not affect the display of these items. + +You MAY additionally provide other profile information. Any information which you provide in your "default" or **public profile** MAY be transmitted to other hubs in $Projectname and additionally MAY be displayed in the channel directory. You can restrict the viewing of this profile information. It may be restricted only to members of your hub, or only connections (friends), or other limited sets of viewers as you desire. If you wish for your profile to be restricted, you must set the appropriate privacy setting, or simply DO NOT provide additional information. + +**Content** + +Content you provide (status posts, photos, files, etc.) belongs to you. $Projectname default is to publish content openly and visible to anybody on the internet (PUBLIC). You MAY control this in your channel settings and restrict the default permissions or you MAY restrict the visibility of any single published item separately (PRIVATE). $Projectname developers will ensure that restricted content is ONLY visible to those in the restriction list - to the best of their ability. + +Content (especially status posts) that you share with other networks or that you have made visible to anybody on the internet (PUBLIC) cannot easily be taken back once it has been published. It MAY be shared with other networks and made available through RSS/Atom feeds. It may also be syndicated on other $Projectname sites. It MAY appear on other networks and websites and be visible in internet searches. If you do not wish this default behaviour please adjust your channel settings and restrict who can see your content. + +**Comments and Forum posts** + +Comments to posts that were created by others and posts which are designated as forum posts belong to you as the creator/author, but the distribution of these posts is not under your direct control, and you relinquish SOME rights to these items. These posts/comments MAY be re-distributed to others, and MAY be visible to anybody on the internet. In the case of comments, the creator of the "first message" in the thread (conversation) to which you are replying controls the distribution of all comments and replies to that message. They "own" and therefore have certain rights with regard to the entire conversation (including all comments contained within it). You can still edit or delete the comment, but the conversation owner also has rights to edit, delete, re-distribute, and backup/restore any or all the content from the conversation. + +**Private Information** + +$Projectname developers will ensure that any content you provide which is designated as PRIVATE will be protected against eavesdropping - to the best of their ability. Private channel content CAN be seen in the database of every involved hub administrator, but private messages are obscured in the database. The latter means that it is very difficult, but NOT impossible for this content to be seen by a hub administrator. Private channel content and private messages are also stripped from email notifications. End to end encryption is provided as an optional feature and this CANNOT be seen, even by a determined administrator. + +[h3]Identity Privacy[/h3] + +Privacy for your identity is another aspect. Because you have a decentralized identity in $Projectname, your privacy extends beyond your home hub. If you want to have complete control of your privacy and security you should run your own hub on a dedicated server. For many people, this is complicated and may stretch their technical abilities. So let's list a few precautions you can make to assure your privacy as much as possible. + +A decentralized identity has a lot of advantages and gives you al lot of interesting features, but you should be aware of the fact that your identity is known by other hubs in $Projectname network. One of those advantages is that other channels can serve you customized content and allow you to see private things (such as private photos which others wish to share with you). Because of this those channels need to know who you are. But we understand that sometimes those other channels know more from you than you might desire. For instance the plug-in Visage that can tell a channel owner the last time you visit their profile. You can easily OPT-OUT of this low level and we think, harmless tracking. + +* You can enable [Do Not Track (DNT)](http://donottrack.us/) in your web browser. We respect this new privacy policy proposal. All modern browsers support DNT. You will find it in the privacy settings of your browsers or else you can consult the web browser's manual. This will not affect the functionality of $Projectname. This setting is probably enough for most people. + +*You can [disable publication](settings) of your channel in our channel directory. If you want people to find your channel, you should give your channel address directly to them. We think this is a good indication that you prefer extra privacy and automatically enable "Do Not Track" if this is the case. + +* You can have a blocked hub. That means that all channels and content on that hub is not public, and not visible to the outside world. This is something only your hub administrator can do. We also respect this and automatically enable "Do Not Track" if it is set. + +[h3]Censorship[/h3] + +$Projectname is a global network which is inclusive of all religions and cultures. This does not imply that every member of the network feels the same way you do on contentious issues, and some people may be STRONGLY opposed to the content you post. In general, if you wish to post something that you know may nor be universally acceptable, the best approach is to restrict the audience using privacy controls to a small circle of friends. + +$Projectname as a network provider is unable to censor content. However, hub administrators MAY censor any content which appears on their hub to comply with local laws or even personal judgement. Their decision is final. If you have issues with any hub administrator, you may move your account and postings to another site which is more in line with your expectations. Please check (periodically) the [Terms of Service](help/TermsOfService) of your hub to learn about any rules or guidelines. If your content consists of material which is illegal or may cause issues, you are STRONGLY encouraged to host your own (become a hub administrator). You may still find that your content is blocked on some hubs, but $Projectname as a network cannot block it from being posted. + +$Projectname RECOMMENDS that hub administrators provide a grace period of 1-2 days between warning an account holder of content that needs to be removed and physically removing or disabling the account. This will give the content owner an opportunity to export their channel meta-data and import it to another site. In rare cases the content may be of such a nature to justify the immediate termination of the account. This is a hub decision, not a $Projectname decision. + +If you typically and regularly post content of an adult or offensive nature, you are STRONGLY encouraged to mark your account "NSFW" (Not Safe For Work). This will prevent the display of your profile photo in the directory except to viewers that have chosen to disable "safe mode". If your profile photo is found by directory administrators to be adult or offensive, the directory administrator MAY flag your profile photo as NSFW. There is currently no official mechanism to contest or reverse this decision, which is why you SHOULD mark your own account NSFW if it is likely to be inappropriate for general audiences. + +[h1]Features[/h1] + +[h2]$Projectname in a Nutshell[/h2] + +TL;DR + +$Projectname provides distributed web publishing and social communications with [b]decentralised permissions[/b]. + +So what exactly are "decentralised permissions"? They give me the ability to share something on my website (photos, media, files, webpages, etc.) with specific people on completely different websites - but not necessarily [i]everybody[/i] on those websites; and they do not need a password on my website and do not need to login to my website to view the things I've shared with them. They have one password on their own website and "magic authentication" between affiliated websites in the network. Also, as it is decentralised, there is no third party which has the ability to bypass permissions and see everything in the network. + +$Projectname combines many features of traditional blogs, social networking and media, content management systems, and personal cloud storage into an easy to use framework. Each node in the grid can operate standalone or link with other nodes to create a super-network; leaving privacy under the control of the original publisher. + +$Projectname is an open source webserver application written originally in PHP/MySQL and is easily installable by those with basic website administration skills. It is also easily extended via plugins and themes and other third-party tools. + +[h2]$Projectname Features[/h2] + + +$Projectname is a general-purpose web publishing and communication network, with several unique features. It is designed to be used by the widest range of people on the web, from non-technical bloggers, to expert PHP programmers and seasoned systems administrators. + +This page lists some of the core features of $Projectname that are bundled with the official release. As with most free and open source software, there may be many other extensions, additions, plugins, themes and configurations that are limited only by the needs and imagination of the members. + +[h2]Built for Privacy and Freedom[/h2] + +One of the design goals of $Projectname is to enable easy communication on the web, while preserving privacy, if so desired by members. To achieve this goal, $Projectname includes a number of features allowing arbitrary levels of privacy: + +[h3]Affinity Slider[/h3] + +When adding connnections in $Projectname, members have the option of assigning "affinity" levels (how close your friendship is) to the new connection. For example, when adding someone who happens to be a person whose blog you follow, you could assign their channel an affinity level of "Acquaintances". + +On the other hand, when adding a friend's channel, they could be placed under the affinity level of "Friends". + +At this point, $Projectname [i]Affinity Slider[/i] tool, which usually appears at the top of your "Matrix" page, adjusts the content on the page to include those within the desired affinity range. Channels outside that range will not be displayed, unless you adjust the slider to include them. + +The Affinity Slider allows instantaneous filtering of large amounts of content, grouped by levels of closeness. + +[h3]Connection Filtering[/h3] + +You have the ability to control precisely what appears in your stream using the optional "Connection Filter". When enabled, the Connection Editor provides inputs for selecting criteria which needs to be matched in order to include or exclude a specific post from a specific channel. Once a post has been allowed, all comments to that post are allowed regardless of whether they match the selection criteria. You may select words that if present block the post or ensure it is included in your stream. Regular expressions may be used for even finer control, as well as hashtags or even the detected language of the post. + +[h3]Access Control Lists[/h3] + +When sharing content, members have the option of restricting who sees the content. By clicking on the padlock underneath the sharing box, one may choose desired recipients of the post, by clicking on their names. + +Once sent, the message will be viewable only by the sender and the selected recipients. In other words, the message will not appear on any public walls. + +Access Control Lists may be applied to content and posts, photos, events, webpages, chatrooms and files. + +[h3]Single Sign-on[/h3] + +Access Control Lists work for all channels in the grid due to our unique single sign-on technology. Most internal links provide an identity token which can be verified on other $Projectname sites and used to control access to private resources. You login once to your home hub. After that, authentication to all $Projectname resources is "magic". + + +[h3]WebDAV enabled File Storage[/h3] + +Files may be uploaded to your personal storage area using your operating system utilities (drag and drop in most cases). You may protect these files with Access Control Lists to any combination of $Projectname members (including some third party network members) or make them public. + +[h3]Photo Albums[/h3] + +Store photos in albums. All your photos may be protected by Access Control Lists. + +[h3]Events Calendar[/h3] + +Create and manage events and tasks, which may also be protected with Access Control Lists. Events can be imported/exported to other software using the industry standard vcalendar/iCal format and shared in posts with others. Birthday events are automatically added from your friends and converted to your correct timezone so that you will know precisely when the birthday occurs - no matter where you are located in the world in relation to the birthday person. Events are normally created with attendance counters so your friends and connections can RSVP instantly. + +[h3]Chatrooms[/h3] + +You may create any number of personal chatrooms and allow access via Access Control Lists. These are typically more secure than XMPP, IRC, and other Instant Messaging transports, though we also allow using these other services via plugins. + +[h3]Webpage Building[/h3] + +$Projectname has many "Content Management" creation tools for building webpages, including layout editing, menus, blocks, widgets, and page/content regions. All of these may be access controlled so that the resulting pages are private to their intended audience. + +[h3]Apps[/h3] + +Apps may be built and distributed by members. These are different from traditional "vendor lockin" apps because they are controlled completely by the author - who can provide access control on the destination app pages and charge accordingly for this access. Most apps in $Projectname are free and can be created easily by those with no programming skills. + +[h3]Layout[/h3] + +Page layout is based on a description language called Comanche. $Projectname is itself written in Comanche layouts which you can change. This allows a level of customisation you won't typically find in so-called "multi-user environments". + +[h3]Bookmarks[/h3] + +Share and save/manage bookmarks from links provided in conversations. + + +[h3]Private Message Encryption and Privacy Concerns[/h3] + +Private mail is stored in an obscured format. While this is not bullet-proof it typically prevents casual snooping by the site administrator or ISP. + +Each $Projectname channel has it's own unique set of private and associated public RSA 4096-bit keys, generated when the channels is first created. This is used to protect private messages and posts in transit. + +Additionally, messages may be created utilising "end-to-end encryption" which cannot be read by $Projectname operators or ISPs or anybody who does not know the passcode. + +Public messages are generally not encrypted in transit or in storage. + +Private messages may be retracted (unsent) although there is no guarantee the recipient hasn't read it yet. + +Posts and messages may be created with an expiration date, at which time they will be deleted/removed on the recipient's site. + + +[h3]Service Federation[/h3] + +In addition to addon "cross-post connectors" to a variety of alternate networks, there is native support for importation of content from RSS/Atom feeds and using this to create special channels. Also, an experimental but working implementation of the Diaspora protocol allows communication with people on the Friendica and Diaspora decentralised social networks. This is currently marked experimental because these networks do not have the same level of privacy and encryption features and abilities as $Projectname and may present privacy risks. + +There is also experimental support for OpenID authentication which may be used in Access Control Lists. This is a work in progress. Your $Projectname hub may be used as an OpenID provider to authenticate you to external services which use this technology. + +Channels may have permissions to become "derivative channels" where two or more existing channels combine to create a new topical channel. + +[h3]Privacy Groups[/h3] + +Our implementation of privacy groups is similar to Google "Circles" and Diaspora "Aspects". This allows you to filter your incoming stream by selected groups, and automatically set the outbound Access Control List to only those in that privacy group when you post. You may over-ride this at any time (prior to sending the post). + + +[h3]Directory Services[/h3] + +We provide easy access to a directory of members and provide decentralised tools capable of providing friend "suggestions". The directories are normal $Projectname sites which have chosen to accept the directory server role. This requires more resources than most typical sites so is not the default. Directories are synchronised and mirrored so that they all contain up-to-date information on the entire network (subject to normal propagation delays). + + +[h3]TLS/SSL[/h3] + +For $Projectname hubs that use TLS/SSL, client to server communications are encrypted via TLS/SSL. Given recent disclosures in the media regarding widespread, global surveillance and encryption circumvention by the NSA and GCHQ, it is reasonable to assume that HTTPS-protected communications may be compromised in various ways. Private communications are consequently encrypted at a higher level before sending offsite. + +[h3]Channel Settings[/h3] + +When a channel is created, a role is chosen which applies a number of pre-configured security and privacy settings. These are chosen for best practives to maintain privacy at the requested levels. + +If you choose a "custom" privacy role, each channel allows fine-grained permissions to be set for various aspects of communication. For example, under the "Security and Privacy Settings" heading, each aspect on the left side of the page, has six (6) possible viewing/access options, that can be selected by clicking on the dropdown menu. There are also a number of other privacy settings you may edit. + +The options are: + + - Nobody except yourself. + - Only those you specifically allow. + - Anybody in your address book. + - Anybody on this website. + - Anybody in this network. + - Anybody authenticated. + - Anybody on the Internet. + + +[h3]Public and Private Forums[/h3] + +Forums are typically channels which may be open to participation from multiple authors. There are currently two mechanisms to post to forums: 1) "wall-to-wall" posts and 2) via forum @mention tags. Forums can be created by anybody and used for any purpose. The directory contains an option to search for public forums. Private forums can only be posted to and often only seen by members. + + +[h3]Account Cloning[/h3] + +Accounts in $Projectname are referred to as [i]nomadic identities[/i], because a member's identity is not bound to the hub where the identity was originally created. For example, when you create a Facebook or Gmail account, it is tied to those services. They cannot function without Facebook.com or Gmail.com. + +By contrast, say you've created a $Projectname identity called [b]tina@$Projectnamehub.com[/b]. You can clone it to another $Projectname hub by choosing the same, or a different name: [b]liveForever@Some$ProjectnameHub.info[/b] + +Both channels are now synchronized, which means all your contacts and preferences will be duplicated on your clone. It doesn't matter whether you send a post from your original hub, or the new hub. Posts will be mirrored on both accounts. + +This is a rather revolutionary feature, if we consider some scenarios: + + - What happens if the hub where an identity is based suddenly goes offline? Without cloning, a member will not be able to communicate until that hub comes back online (no doubt many of you have seen and cursed the Twitter "Fail Whale"). With cloning, you just log into your cloned account, and life goes on happily ever after. + + - The administrator of your hub can no longer afford to pay for his free and public $Projectname hub. He announces that the hub will be shutting down in two weeks. This gives you ample time to clone your identity(ies) and preserve your$Projectname relationships, friends and content. + + - What if your identity is subject to government censorship? Your hub provider may be compelled to delete your account, along with any identities and associated data. With cloning, $Projectname offers [b]censorship resistance[/b]. You can have hundreds of clones, if you wanted to, all named different, and existing on many different hubs, strewn around the internet. + +$Projectname offers interesting new possibilities for privacy. You can read more at the <<Private Communications Best Practices>> page. + +Some caveats apply. For a full explanation of identity cloning, read the <HOW TO CLONE MY IDENTITY>. + +[h3]Multiple Profiles[/h3] + +Any number of profiles may be created containing different information and these may be made visible to certain of your connections/friends. A "default" profile can be seen by anybody and may contain limited information, with more information available to select groups or people. This means that the profile (and site content) your beer-drinking buddies see may be different than what your co-workers see, and also completely different from what is visible to the general public. + +[h3]Account Backup[/h3] + +Red offers a simple, one-click account backup, where you can download a complete backup of your profile(s). + +Backups can then be used to clone or restore a profile. + +[h3]Account Deletion[/h3] + +Accounts can be immediately deleted by clicking on a link. That's it. All associated content is then deleted from the grid (this includes posts and any other content produced by the deleted profile). Depending on the number of connections you have, the process of deleting remote content could take some time but it is scheduled to happen as quickly as is practical. + +[h3][size=20]Content Creation[/h2] + +[h3]Writing Posts[/h3] + +$Projectname supports a number of different ways of adding rich-text content. The default is a custom variant of BBcode, tailored for use in $Projectname. You may also enable the use of Markdown if you find that easier to work with. A visual editor may also be used. The traditional visual editor for $Projectname had some serious issues and has since been removed. We are currently looking for a replacement. + +When creating "Websites", content may be entered in HTML, Markdown, BBcode, and/or plain text. + +[h3]Deletion of content[/h3] +Any content created in $Projectname remains under the control of the member (or channel) that originally created it. At any time, a member can delete a message, or a range of messages. The deletion process ensures that the content is deleted, regardless of whether it was posted on a channel's primary (home) hub, or on another hub, where the channel was remotely authenticated via Zot ($Projectname communication and authentication protocol). + +[h3]Media[/h3] +Similar to any other modern blogging system, social network, or a micro-blogging service, $Projectname supports the uploading of files, embedding of videos, linking web pages. + +[h3]Previewing/Editing[/h3] +Post can be previewed prior to sending and edited after sending. + +[h3]Voting/Consensus[/h3] +Posts can be turned into "consensus" items which allows readers to offer feedback, which is collated into "agree", "disagree", and "abstain" counters. This lets you gauge interest for ideas and create informal surveys. + + +[h3]Extending $Projectname[/h3] + +$Projectname can be extended in a number of ways, through site customisation, personal customisation, option setting, themes, and addons/plugins. + +[h3]API[/h3] + +An API is available for use by third-party services. This is based originally on the early Twitter API (for which hundreds of third-party tools exist). It is currently being extended to provide access to facilities and abilities which are specific to $Projectname. Access may be provided by login/password or OAuth and client registration of OAuth applications is provided. + + + + +[h1]What is Zot?[/h1] + +Zot is the protocol that powers $Projectname, providing three core capabilities: Communications, Identity, and Access Control. + +The functionality it provides can also be described as follows: + + - a relationship online is just a bunch of permissions + - the internet is just another folder + +[h2]Communications[/h2] + +Zot is a revolutionary protocol which provides [i]decentralised communications[/i] and [i]identity management[/i] across the grid. The resulting platform can provide web services comparable to those offered by large corporate providers, but without the large corporate provider and their associated privacy issues, insatiable profit drive, and walled-garden mentality. + +Communications and social networking are an integral part of the grid. Any channel (and any services provided by that channel) can make full use of feature-rich social communications on a global scale. These communications may be public or private - and private communications comprise not only fully encrypted transport, but also encrypted storage to help protect against accidental snooping and disclosure by rogue system administrators and internet service providers. + +Zot allows a wide array of background services in the grid, from offering friend suggestions, to directory services. You can also perform other things which would typically only be possibly on a centralized provider - such as "Wall to Wall" posts. Private/multiple profiles can be easily created, and web content can be tailored to the viewer via the [i]Affinity Slider[/i]. + +You won't find these features at all on other decentralized communication services. In addition to providing hub (server) decentralization, perhaps the most innovative and interesting Zot feature is its provision of [i]decentralized identity[/i] services. + +[h2]Identity[/h2] + +Zot's identity layer is unique. It provides [i]invisible single sign-on[/i] across all sites in the grid. + +It also provides [i]nomadic identity[/i], so that your communications with friends, family, and or anyone else you're communicating with won't be affected by the loss of your primary communication node - either temporarily or permanently. + +The important bits of your identity and relationships can be backed up to a thumb drive, or your laptop, and may appear at any node in the grid at any time - with all your friends and preferences intact. + +Crucially, these nomadic instances are kept in sync so any instance can take over if another one is compromised or damaged. This protects you against not only major system failure, but also temporary site overloads and governmental manipulation or censorship. + +Nomadic identity, single sign-on, and $Projectname's decentralization of hubs, we believe, introduce a high degree of degree of [i]resiliency[/i] and [i]persistence[/i] in internet communications, that are sorely needed amidst global trends towards corporate centralization, as well as mass and indiscriminate government surveillance and censorship. + +As you browse the grid, viewing channels and their unique content, you are seamlessly authenticated as you go, even across completely different server hubs. No passwords to enter. Nothing to type. You're just greeted by name on every new site you visit. + +How does Zot do that? We call it [i]magic-auth[/i], because $Projectname hides the details of the complexities that go into single sign-on logins, and nomadic identities, from the experience of browsing on the grid. This is one of the design goals of $Projectname: to increase privacy, and freedom on the web, while reducing the complexity and tedium brought by the need to enter new passwords and user names for every different sight that someone might visit online. + +You login only once on your home hub (or any nomadic backup hub you have chosen). This allows you to access any authenticated services provided anywhere in the grid - such as shopping, blogs, forums, and access to private information. This is just like the services offered by large corporate providers with huge user databases; however you can be a member of this community, as well as a server on this network using a $35 Rasberry Pi. Your password isn't stored on a thousand different sites, or even worse, only on a few sites like Google and Facebook, beyond your direct control. + +You cannot be silenced. You cannot be removed from the grid, unless you yourself choose to exit it. + +[h2]Access Control[/h2] + +Zot's identity layer allows you to provide fine-grained permissions to any content you wish to publish - and these permissions extend across $Projectname. This is like having one super huge website made up of an army of small individual websites - and where each channel in the grid can completely control their privacy and sharing preferences for any web resources they create. + +Currently, the grid supports communications, photo albums, events, and files. This will be extended in the future to provide content management services (web pages) and cloud storage facilities, such as WebDAV and multi-media libraries. Every object and how it is shared and with whom is completely under your control. + +This type of control is available on large corporate providers such as Facebook and Google, because they own the user database. Within the grid, there is no need for a huge user databaseon your machine - because the grid [i]is[/i] your user database. It has what is essentially infinite capacity (limited by the total number of hubs online across the internet), and is spread amongst hundreds, and potentially millions of computers. + +Access can be granted or denied for any resource, to any channel, or any group of channels; anywhere within the grid. Others can access your content if you permit them to do so, and they do not even need to have an account on your hub. Your private photos cannot be viewed, because permission really work; they are not an addon that was added as an afterthought. If you aren't on the list of allowed viewers for a particular photo, you aren't going to look at it. + + +[h1]Credits[/h1] + +Thanks to all who have helped and contributed to the project and its predecessors over the years. +It is possible we missed in your name but this is unintentional. We also thank the community and +its members for providing valuable input and without whom this entire effort would be meaningless. + +It is also worth acknowledging the contributions and solutions to problems which arose from +discussions amongst members and developers of other somewhat related and competing projects; +even if we have had our occasional disagreements. + +[list] +[li]Mike Macgirvin[/li] +[li]Fabio Comuni[/li] +[li]Simon L'nu[/li] +[li]marijus[/li] +[li]Tobias Diekershoff[/li] +[li]fabrixxm[/li] +[li]tommy tomson[/li] +[li]Simon[/li] +[li]zottel[/li] +[li]Christian Vogeley[/li] +[li]Jeroen van Riet Paap (jeroenpraat)[/li] +[li]Michael Vogel[/li] +[li]erik[/li] +[li]Zach Prezkuta[/li] +[li]Paolo T[/li] +[li]Michael Meer[/li] +[li]Michael[/li] +[li]Abinoam P.

It allows anybody to publicly or <strong>privately</strong> publish a range of web/media/personal content. The cross-domain privacy implementation is unique and somewhat revolutionary, as identity and access rights are negotiated by servers invisibly in the background.<br><br>Hubzilla is free and open source. It is designed to scale from a $35 Raspberry Pi, to top of the line AMD and Intel Xeon-powered multi-core enterprise servers. It can be used to support communication between a few individuals, or scale to many thousands and more.<br><br>Hubzilla aims to be skill and resource agnostic. It is easy to use by everyday people, as well as by systems administrators and developers. <br><br>How you use it depends on how you want to use it. <br><br>It is written in the PHP scripting language, thus making it trivial to install on any hosting platform in use today. This includes self-hosting at home, at hosting providers such as <a href="http://mediatemple.com/">Media Temple</a> and <a href="http://www.dreamhost.com/">Dreamhost</a>, or on virtual and dedicated servers, offered by the likes of <a href="https://www.linode.com">Linode</a>, <a href="http://greenqloud.com">GreenQloud</a> or <a href="https://aws.amazon.com">Amazon AWS</a>.<br><br>In other words, Hubzilla can run on any computing platform that comes with a web server, a MySQL-compatible database, and the PHP scripting language. <br><br>Along the way, Hubzilla offers a number of unique goodies: <br><br><strong>Single-click user identification:</strong> meaning you can access sites on Hubzilla simply by clicking on links to remote sites. Authentication just happens automagically behind the scenes. Forget about remembering multiple user names with multiple passwords when accessing different sites online.<br><br><strong>Cloning:</strong> of online identities. Your online presence no longer has to be tied to a single server, domain name or IP address. You can clone and import your identity (or channel as we call it) to another server (or, a hub as servers are known in Hubzilla). Now, should your primary hub go down, no worries, your contacts, posts<em>*</em>, and messages<em>*</em> will automagically continue to be available and accessible under your cloned channel. <em>(*: only posts and messages as from the moment you cloned your channel)</em><br><br><strong>Privacy:</strong> Hubzilla identities (Zot IDs) can be deleted, backed up/downloaded, and cloned. The user is in full control of their data. Should you decide to delete all your content and erase your Zot ID, all you have to do is click on a link and it's immediately deleted from the hub. No questions, no fuss. -</p> - -<h2 id="resources-links">Resources and Links</h2> -<ul> - <li><a href="http://hubzilla.org">Hubzilla project website</a></li> - <li><a href="https://github.com/redmatrix/hubzilla">Hubzilla core code repository</a></li> - <li><a href="https://github.com/redmatrix/hubzilla-addons">Hubzilla official addons repository</a></li> -</ul> - -<h2 id="project-governance">Governance</h2> - -<br><br>Governance relates to the management of a project and particularly how this relates to conflict resolution.<br><br><h3>Community Governance</h3><br><br>The project is maintained and decisions made by the 'community'. The governance structure is still evolving. Until the structure is finalised, decisions are made in the following order:<br><br><ul class="listdecimal" style="list-style-type: decimal;"><li> Lazy Consensus<br><br>If a project proposal is made to one of the community governance forums and there are no serious objections in a "reasonable" amount of time from date of proposal (we usually provide 2-3 days for all interested parties to weigh in), no vote needs to be taken and the proposal will be considered approved. Some concerns may be raised at this time, but if these are addressed during discussion and work-arounds provided, it will still be considered approved. <br></li><li> Veto<br><br>Senior developers with a significant history of project commits may veto any decision. The decision may not proceed until the veto is removed or an alternative proposal is presented.<br></li><li> Community Vote<br><br>A decision which does not have a clear mandate or clear consensus, but is not vetoed, can be taken to a community vote. At present this is a simple popular vote in one of the applicable community forums. At this time, popular vote decides the outcome. This may change in the future if the community adopts a 'council' governance model. This document will be updated at that time with the updated governance rules. <br></li></ul><br><br>Community Voting does not always provide a pleasant outcome and can generate polarised factions in the community (hence the reason why other models are under consideration). If the proposal is 'down voted' there are still several things which can be done and the proposal re-submitted with slightly different parameters (convert to an addon, convert to an optional feature which is disabled by default, etc.). If interest in the feature is high and the vote is "close", it can generate lots of bad feelings amongst the losing voters. On such close votes, it is <strong>strongly recommended</strong> that the proposer take steps to address any concerns that were raised and re-submit. - - - -<h2 id="project-privacy-policy">Privacy Policy</h2> - -<h3>Summary</h3> - -<p>Q: Who can see my content?</p> - -<p>A: By default ANYBODY on the internet, UNLESS you restrict it. Hubzilla allows you to choose the privacy level you desire. Restricted content will NOT be visible to "spy networks" and advertisers. It will be protected against eavesdropping by outsiders - to the best of our ability. Hub administrators with sufficient skills and patience MAY be able to eavesdrop on some private communications but they must expend effort to do so. Privacy modes exist within Hubzilla which are even resistant to eavesdropping by skilled and determined hub administrators.</p> - -<p>Q: Can my content be censored?</p> - -<p>A: Hubzilla (the network) CANNOT censor your content. Server and hub administrators are subject to local laws and MAY remove objectionable content from their site/hub. Anybody MAY become a hub administrator, including you; and therefore publish content which might otherwise be censored. You still MAY be subject to local laws.</p> - -<h3>Definitions</h3> - -<p><strong>Hubzilla</strong></p> - -<p>Otherwise referred to as "the network", Hubzilla is a collection of individual computers/servers (aka <strong>hubs</strong>) which connect together to form a larger cooperative network.</p> - -<p><strong>hub</strong></p> - -<p>An individual computer or server connected to Hubzilla. These are provided by a <strong>hub administrator</strong> and may be public or private, paid or free.</p> - -<p><strong>hub administrator</strong></p> - -<p>The system operator of an individual hub.</p> - -<h3>Policies</h3> - -<p><strong>Public Information</strong></p> - -<p>Any information or anything posted by you within Hubzilla MAY be public or visible to anybody on the internet. To the extent possible, Hubzilla allows you to protect content and restrict who can view it.</p> - -<p>Your profile photo, your channel name, and the location (URL or network address) of your channel are visible to anybody on the internet and privacy controls will not affect the display of these items.</p> - -<p>You MAY additionally provide other profile information. Any information which you provide in your "default" or <strong>public profile</strong> MAY be transmitted to other hubs in Hubzilla and additionally MAY be displayed in the channel directory. You can restrict the viewing of this profile information. It may be restricted only to members of your hub, or only connections (friends), or other limited sets of viewers as you desire. If you wish for your profile to be restricted, you must set the appropriate privacy setting, or simply DO NOT provide additional information.</p> - -<p><strong>Content</strong></p> - -<p>Content you provide (status posts, photos, files, etc.) belongs to you. Hubzilla default is to publish content openly and visible to anybody on the internet (PUBLIC). You MAY control this in your channel settings and restrict the default permissions or you MAY restrict the visibility of any single published item separately (PRIVATE). Hubzilla developers will ensure that restricted content is ONLY visible to those in the restriction list - to the best of their ability.</p> - -<p>Content (especially status posts) that you share with other networks or that you have made visible to anybody on the internet (PUBLIC) cannot easily be taken back once it has been published. It MAY be shared with other networks and made available through RSS/Atom feeds. It may also be syndicated on other Hubzilla sites. It MAY appear on other networks and websites and be visible in internet searches. If you do not wish this default behaviour please adjust your channel settings and restrict who can see your content.</p> - -<p><strong>Comments and Forum posts</strong></p> - -<p>Comments to posts that were created by others and posts which are designated as forum posts belong to you as the creator/author, but the distribution of these posts is not under your direct control, and you relinquish SOME rights to these items. These posts/comments MAY be re-distributed to others, and MAY be visible to anybody on the internet. In the case of comments, the creator of the "first message" in the thread (conversation) to which you are replying controls the distribution of all comments and replies to that message. They "own" and therefore have certain rights with regard to the entire conversation (including all comments contained within it). You can still edit or delete the comment, but the conversation owner also has rights to edit, delete, re-distribute, and backup/restore any or all the content from the conversation.</p> - -<p><strong>Private Information</strong></p> - -<p>Hubzilla developers will ensure that any content you provide which is designated as PRIVATE will be protected against eavesdropping - to the best of their ability. Private channel content CAN be seen in the database of every involved hub administrator, but private messages are obscured in the database. The latter means that it is very difficult, but NOT impossible for this content to be seen by a hub administrator. Private channel content and private messages are also stripped from email notifications. End to end encryption is provided as an optional feature and this CANNOT be seen, even by a determined administrator.</p> - -<h3>Identity Privacy</h3> - -<p>Privacy for your identity is another aspect. Because you have a decentralized identity in Hubzilla, your privacy extends beyond your home hub. If you want to have complete control of your privacy and security you should run your own hub on a dedicated server. For many people, this is complicated and may stretch their technical abilities. So let's list a few precautions you can make to assure your privacy as much as possible.</p> - -<p>A decentralized identity has a lot of advantages and gives you al lot of interesting features, but you should be aware of the fact that your identity is known by other hubs in Hubzilla network. One of those advantages is that other channels can serve you customized content and allow you to see private things (such as private photos which others wish to share with you). Because of this those channels need to know who you are. But we understand that sometimes those other channels know more from you than you might desire. For instance the plug-in Visage that can tell a channel owner the last time you visit their profile. You can easily OPT-OUT of this low level and we think, harmless tracking.</p> - -<ul> -<li>You can enable <a href="http://donottrack.us/">Do Not Track (DNT)</a> in your web browser. We respect this new privacy policy proposal. All modern browsers support DNT. You will find it in the privacy settings of your browsers or else you can consult the web browser's manual. This will not affect the functionality of Hubzilla. This setting is probably enough for most people.</li> -<br> - -<li>You can <a href="settings">disable publication</a> of your channel in our channel directory. If you want people to find your channel, you should give your channel address directly to them. We think this is a good indication that you prefer extra privacy and automatically enable "Do Not Track" if this is the case.</li> -<br> - -<li>You can have a blocked hub. That means that all channels and content on that hub is not public, and not visible to the outside world. This is something only your hub administrator can do. We also respect this and automatically enable "Do Not Track" if it is set.</li> -</ul> - -<h3>Censorship</h3> - -<p>Hubzilla is a global network which is inclusive of all religions and cultures. This does not imply that every member of the network feels the same way you do on contentious issues, and some people may be STRONGLY opposed to the content you post. In general, if you wish to post something that you know may nor be universally acceptable, the best approach is to restrict the audience using privacy controls to a small circle of friends.</p> - -<p>Hubzilla as a network provider is unable to censor content. However, hub administrators MAY censor any content which appears on their hub to comply with local laws or even personal judgement. Their decision is final. If you have issues with any hub administrator, you may move your account and postings to another site which is more in line with your expectations. Please check (periodically) the <a href="help/TermsOfService">Terms of Service</a> of your hub to learn about any rules or guidelines. If your content consists of material which is illegal or may cause issues, you are STRONGLY encouraged to host your own (become a hub administrator). You may still find that your content is blocked on some hubs, but Hubzilla as a network cannot block it from being posted.</p> - -<p>Hubzilla RECOMMENDS that hub administrators provide a grace period of 1-2 days between warning an account holder of content that needs to be removed and physically removing or disabling the account. This will give the content owner an opportunity to export their channel meta-data and import it to another site. In rare cases the content may be of such a nature to justify the immediate termination of the account. This is a hub decision, not a Hubzilla decision.</p> - -<p>If you typically and regularly post content of an adult or offensive nature, you are STRONGLY encouraged to mark your account "NSFW" (Not Safe For Work). This will prevent the display of your profile photo in the directory except to viewers that have chosen to disable "safe mode". If your profile photo is found by directory administrators to be adult or offensive, the directory administrator MAY flag your profile photo as NSFW. There is currently no official mechanism to contest or reverse this decision, which is why you SHOULD mark your own account NSFW if it is likely to be inappropriate for general audiences.</p> - - - -<h1 id="features">Features</h1> -<p> - <strong><span style="font-size: 24px;">Hubzilla in a Nutshell</span></strong><br><br>TL;DR <br><br>Hubzilla provides distributed web publishing and social communications with <strong>decentralised permissions</strong>.<br><br>So what exactly are "decentralised permissions"? They give me the ability to share something on my website (photos, media, files, webpages, etc.) with specific people on completely different websites - but not necessarily <em>everybody</em> on those websites; and they do not need a password on my website and do not need to login to my website to view the things I've shared with them. They have one password on their own website and "magic authentication" between affiliated websites in the network. Also, as it is decentralised, there is no third party which has the ability to bypass permissions and see everything in the network.<br><br>Hubzilla combines many features of traditional blogs, social networking and media, content management systems, and personal cloud storage into an easy to use framework. Each node in the grid can operate standalone or link with other nodes to create a super-network; leaving privacy under the control of the original publisher. <br><br>Hubzilla is an open source webserver application written originally in PHP/MySQL and is easily installable by those with basic website administration skills. It is also easily extended via plugins and themes and other third-party tools. <br><br><strong><span style="font-size: 24px;">Hubzilla Features</span></strong><br><br><br>Hubzilla is a general-purpose web publishing and communication network, with several unique features. It is designed to be used by the widest range of people on the web, from non-technical bloggers, to expert PHP programmers and seasoned systems administrators.<br><br>This page lists some of the core features of Hubzilla that are bundled with the official release. As with most free and open source software, there may be many other extensions, additions, plugins, themes and configurations that are limited only by the needs and imagination of the members.<br><br><strong><span style="font-size: 20px;">Built for Privacy and Freedom</span></strong><br><br>One of the design goals of Hubzilla is to enable easy communication on the web, while preserving privacy, if so desired by members. To achieve this goal, Hubzilla includes a number of features allowing arbitrary levels of privacy:<br><br><strong>Affinity Slider</strong><br><br>When adding connnections in Hubzilla, members have the option of assigning "affinity" levels (how close your friendship is) to the new connection. For example, when adding someone who happens to be a person whose blog you follow, you could assign their channel an affinity level of "Acquaintances". <br><br>On the other hand, when adding a friend's channel, they could be placed under the affinity level of "Friends".<br><br>At this point, Hubzilla <em>Affinity Slider</em> tool, which usually appears at the top of your "Matrix" page, adjusts the content on the page to include those within the desired affinity range. Channels outside that range will not be displayed, unless you adjust the slider to include them.<br><br>The Affinity Slider allows instantaneous filtering of large amounts of content, grouped by levels of closeness.<br><br><strong>Connection Filtering</strong><br><br>You have the ability to control precisely what appears in your stream using the optional "Connection Filter". When enabled, the Connection Editor provides inputs for selecting criteria which needs to be matched in order to include or exclude a specific post from a specific channel. Once a post has been allowed, all comments to that post are allowed regardless of whether they match the selection criteria. You may select words that if present block the post or ensure it is included in your stream. Regular expressions may be used for even finer control, as well as hashtags or even the detected language of the post. <br><br><strong>Access Control Lists</strong><br><br>When sharing content, members have the option of restricting who sees the content. By clicking on the padlock underneath the sharing box, one may choose desired recipients of the post, by clicking on their names.<br><br>Once sent, the message will be viewable only by the sender and the selected recipients. In other words, the message will not appear on any public walls.<br><br>Access Control Lists may be applied to content and posts, photos, events, webpages, chatrooms and files. <br><br><strong>Single Sign-on</strong><br><br>Access Control Lists work for all channels in the grid due to our unique single sign-on technology. Most internal links provide an identity token which can be verified on other Hubzilla sites and used to control access to private resources. You login once to your home hub. After that, authentication to all Hubzilla resources is "magic".<br><br><br><strong>WebDAV enabled File Storage</strong><br><br>Files may be uploaded to your personal storage area using your operating system utilities (drag and drop in most cases). You may protect these files with Access Control Lists to any combination of Hubzilla members (including some third party network members) or make them public.<br><br><strong>Photo Albums</strong><br><br>Store photos in albums. All your photos may be protected by Access Control Lists.<br><br><strong>Events Calendar</strong><br><br>Create and manage events and tasks, which may also be protected with Access Control Lists. Events can be imported/exported to other software using the industry standard vcalendar/iCal format and shared in posts with others. Birthday events are automatically added from your friends and converted to your correct timezone so that you will know precisely when the birthday occurs - no matter where you are located in the world in relation to the birthday person. Events are normally created with attendance counters so your friends and connections can RSVP instantly. <br><br><strong>Chatrooms</strong><br><br>You may create any number of personal chatrooms and allow access via Access Control Lists. These are typically more secure than XMPP, IRC, and other Instant Messaging transports, though we also allow using these other services via plugins. <br><br><strong>Webpage Building</strong><br><br>Hubzilla has many "Content Management" creation tools for building webpages, including layout editing, menus, blocks, widgets, and page/content regions. All of these may be access controlled so that the resulting pages are private to their intended audience. <br><br><strong>Apps</strong><br><br>Apps may be built and distributed by members. These are different from traditional "vendor lockin" apps because they are controlled completely by the author - who can provide access control on the destination app pages and charge accordingly for this access. Most apps in Hubzilla are free and can be created easily by those with no programming skills. <br><br><strong>Layout</strong><br><br>Page layout is based on a description language called Comanche. Hubzilla is itself written in Comanche layouts which you can change. This allows a level of customisation you won't typically find in so-called "multi-user environments".<br><br><strong>Bookmarks</strong><br><br>Share and save/manage bookmarks from links provided in conversations. <br> <br> <br><strong>Private Message Encryption and Privacy Concerns</strong><br><br>Private mail is stored in an obscured format. While this is not bullet-proof it typically prevents casual snooping by the site administrator or ISP. <br><br>Each Hubzilla channel has it's own unique set of private and associated public RSA 4096-bit keys, generated when the channels is first created. This is used to protect private messages and posts in transit.<br><br>Additionally, messages may be created utilising "end-to-end encryption" which cannot be read by Hubzilla operators or ISPs or anybody who does not know the passcode. <br><br>Public messages are generally not encrypted in transit or in storage. <br><br>Private messages may be retracted (unsent) although there is no guarantee the recipient hasn't read it yet.<br><br>Posts and messages may be created with an expiration date, at which time they will be deleted/removed on the recipient's site. <br><br><br><strong>Service Federation</strong><br><br>In addition to addon "cross-post connectors" to a variety of alternate networks, there is native support for importation of content from RSS/Atom feeds and using this to create special channels. Also, an experimental but working implementation of the Diaspora protocol allows communication with people on the Friendica and Diaspora decentralised social networks. This is currently marked experimental because these networks do not have the same level of privacy and encryption features and abilities as Hubzilla and may present privacy risks.<br><br>There is also experimental support for OpenID authentication which may be used in Access Control Lists. This is a work in progress. Your Hubzilla hub may be used as an OpenID provider to authenticate you to external services which use this technology. <br><br>Channels may have permissions to become "derivative channels" where two or more existing channels combine to create a new topical channel. <br><br><strong>Privacy Groups</strong><br><br>Our implementation of privacy groups is similar to Google "Circles" and Diaspora "Aspects". This allows you to filter your incoming stream by selected groups, and automatically set the outbound Access Control List to only those in that privacy group when you post. You may over-ride this at any time (prior to sending the post). <br><br><br><strong>Directory Services</strong><br><br>We provide easy access to a directory of members and provide decentralised tools capable of providing friend "suggestions". The directories are normal Hubzilla sites which have chosen to accept the directory server role. This requires more resources than most typical sites so is not the default. Directories are synchronised and mirrored so that they all contain up-to-date information on the entire network (subject to normal propagation delays). <br> <br><br><strong>TLS/SSL</strong><br><br>For Hubzilla hubs that use TLS/SSL, client to server communications are encrypted via TLS/SSL. Given recent disclosures in the media regarding widespread, global surveillance and encryption circumvention by the NSA and GCHQ, it is reasonable to assume that HTTPS-protected communications may be compromised in various ways. Private communications are consequently encrypted at a higher level before sending offsite.<br><br><strong>Channel Settings</strong><br><br>When a channel is created, a role is chosen which applies a number of pre-configured security and privacy settings. These are chosen for best practives to maintain privacy at the requested levels. <br><br>If you choose a "custom" privacy role, each channel allows fine-grained permissions to be set for various aspects of communication. For example, under the "Security and Privacy Settings" heading, each aspect on the left side of the page, has six (6) possible viewing/access options, that can be selected by clicking on the dropdown menu. There are also a number of other privacy settings you may edit. <br><br>The options are:<br><br> - Nobody except yourself.<br> - Only those you specifically allow.<br> - Anybody in your address book.<br> - Anybody on this website.<br> - Anybody in this network.<br> - Anybody authenticated.<br> - Specific people you provide a Guest Access Token to in order to access a specific item.<br> - Anybody on the Internet.<br><br><br><strong>Public and Private Forums</strong><br><br>Forums are typically channels which may be open to participation from multiple authors. There are currently two mechanisms to post to forums: 1) "wall-to-wall" posts and 2) via forum @mention tags. Forums can be created by anybody and used for any purpose. The directory contains an option to search for public forums. Private forums can only be posted to and often only seen by members.<br><br><br><strong>Account Cloning</strong><br><br>Accounts in Hubzilla are referred to as <em>nomadic identities</em>, because a member's identity is not bound to the hub where the identity was originally created. For example, when you create a Facebook or Gmail account, it is tied to those services. They cannot function without Facebook.com or Gmail.com. <br><br>By contrast, say you've created a Hubzilla identity called <strong>tina@Hubzillahub.com</strong>. You can clone it to another Hubzilla hub by choosing the same, or a different name: <strong>liveForever@SomeHubzillaHub.info</strong><br><br>Both channels are now synchronized, which means all your contacts and preferences will be duplicated on your clone. It doesn't matter whether you send a post from your original hub, or the new hub. Posts will be mirrored on both accounts.<br><br>This is a rather revolutionary feature, if we consider some scenarios:<br><br> - What happens if the hub where an identity is based suddenly goes offline? Without cloning, a member will not be able to communicate until that hub comes back online (no doubt many of you have seen and cursed the Twitter "Fail Whale"). With cloning, you just log into your cloned account, and life goes on happily ever after. <br><br> - The administrator of your hub can no longer afford to pay for his free and public Hubzilla hub. He announces that the hub will be shutting down in two weeks. This gives you ample time to clone your identity(ies) and preserve yourHubzilla relationships, friends and content.<br><br> - What if your identity is subject to government censorship? Your hub provider may be compelled to delete your account, along with any identities and associated data. With cloning, Hubzilla offers <strong>censorship resistance</strong>. You can have hundreds of clones, if you wanted to, all named different, and existing on many different hubs, strewn around the internet. <br><br>Hubzilla offers interesting new possibilities for privacy. You can read more at the <<Private Communications Best Practices>> page.<br><br>Some caveats apply. For a full explanation of identity cloning, read the <HOW TO CLONE MY IDENTITY>.<br><br><strong>Multiple Profiles</strong><br><br>Any number of profiles may be created containing different information and these may be made visible to certain of your connections/friends. A "default" profile can be seen by anybody and may contain limited information, with more information available to select groups or people. This means that the profile (and site content) your beer-drinking buddies see may be different than what your co-workers see, and also completely different from what is visible to the general public. <br><br><strong>Account Backup</strong><br><br>Hubzilla offers a simple, one-click account backup, where you can download a complete backup of your profile(s). <br><br>Backups can then be used to clone or restore a profile.<br><br><strong>Account Deletion</strong><br><br>Accounts can be immediately deleted by clicking on a link. That's it. All associated content is then deleted from the grid (this includes posts and any other content produced by the deleted profile). Depending on the number of connections you have, the process of deleting remote content could take some time but it is scheduled to happen as quickly as is practical.<br><br><strong><span style="font-size: 20px;">Content Creation</span></strong><br><br><strong>Writing Posts</strong><br><br>Hubzilla supports a number of different ways of adding rich-text content. The default is a custom variant of BBcode, tailored for use in Hubzilla. You may also enable the use of Markdown if you find that easier to work with. A visual editor may also be used. The traditional visual editor for Hubzilla had some serious issues and has since been removed. We are currently looking for a replacement. <br><br>When creating "Websites", content may be entered in HTML, Markdown, BBcode, and/or plain text.<br><br><strong>Deletion of content</strong><br>Any content created in Hubzilla remains under the control of the member (or channel) that originally created it. At any time, a member can delete a message, or a range of messages. The deletion process ensures that the content is deleted, regardless of whether it was posted on a channel's primary (home) hub, or on another hub, where the channel was remotely authenticated via Zot (Hubzilla communication and authentication protocol).<br><br><strong>Media</strong><br>Similar to any other modern blogging system, social network, or a micro-blogging service, Hubzilla supports the uploading of files, embedding of videos, linking web pages.<br><br><strong>Previewing/Editing</strong> <br>Post can be previewed prior to sending and edited after sending.<br><br><strong>Voting/Consensus</strong><br>Posts can be turned into "consensus" items which allows readers to offer feedback, which is collated into "agree", "disagree", and "abstain" counters. This lets you gauge interest for ideas and create informal surveys. <br><br><br><strong>Extending Hubzilla</strong><br><br>Hubzilla can be extended in a number of ways, through site customisation, personal customisation, option setting, themes, and addons/plugins. <br><br><strong>API</strong><br><br>An API is available for use by third-party services. Access may be provided by login/password or OAuth and client registration of OAuth applications is provided. Also available is a Twitter API <em>plugin</em> which provides compatibility with dozens of third-party clients and apps. -</p> - -<h1 id="zot">Zot protocol</h1> -<p> - <strong>What is Zot?</strong><br><br>Zot is the protocol that powers Hubzilla, providing three core capabilities: Communications, Identity, and Access Control.<br><br>The functionality it provides can also be described as follows: <br><br> - a relationship online is just a bunch of permissions<br> - the internet is just another folder<br><br><strong><span style="font-size: 20px;">Communications</span></strong><br><br>Zot is a revolutionary protocol which provides <em>decentralised communications</em> and <em>identity management</em> across the grid. The resulting platform can provide web services comparable to those offered by large corporate providers, but without the large corporate provider and their associated privacy issues, insatiable profit drive, and walled-garden mentality.<br><br>Communications and social networking are an integral part of the grid. Any channel (and any services provided by that channel) can make full use of feature-rich social communications on a global scale. These communications may be public or private - and private communications comprise not only fully encrypted transport, but also encrypted storage to help protect against accidental snooping and disclosure by rogue system administrators and internet service providers. <br><br>Zot allows a wide array of background services in the grid, from offering friend suggestions, to directory services. You can also perform other things which would typically only be possibly on a centralized provider - such as "Wall to Wall" posts. Private/multiple profiles can be easily created, and web content can be tailored to the viewer via the <em>Affinity Slider</em>. <br><br>You won't find these features at all on other decentralized communication services. In addition to providing hub (server) decentralization, perhaps the most innovative and interesting Zot feature is its provision of <em>decentralized identity</em> services.<br><br><strong><span style="font-size: 20px;">Identity</span></strong> <br><br>Zot's identity layer is unique. It provides <em>invisible single sign-on</em> across all sites in the grid. <br><br>It also provides <em>nomadic identity</em>, so that your communications with friends, family, and or anyone else you're communicating with won't be affected by the loss of your primary communication node - either temporarily or permanently. <br><br>The important bits of your identity and relationships can be backed up to a thumb drive, or your laptop, and may appear at any node in the grid at any time - with all your friends and preferences intact. <br><br>Crucially, these nomadic instances are kept in sync so any instance can take over if another one is compromised or damaged. This protects you against not only major system failure, but also temporary site overloads and governmental manipulation or censorship. <br><br>Nomadic identity, single sign-on, and Hubzilla's decentralization of hubs, we believe, introduce a high degree of degree of <em>resiliency</em> and <em>persistence</em> in internet communications, that are sorely needed amidst global trends towards corporate centralization, as well as mass and indiscriminate government surveillance and censorship.<br><br>As you browse the grid, viewing channels and their unique content, you are seamlessly authenticated as you go, even across completely different server hubs. No passwords to enter. Nothing to type. You're just greeted by name on every new site you visit. <br><br>How does Zot do that? We call it <em>magic-auth</em>, because Hubzilla hides the details of the complexities that go into single sign-on logins, and nomadic identities, from the experience of browsing on the grid. This is one of the design goals of Hubzilla: to increase privacy, and freedom on the web, while reducing the complexity and tedium brought by the need to enter new passwords and user names for every different sight that someone might visit online.<br><br>You login only once on your home hub (or any nomadic backup hub you have chosen). This allows you to access any authenticated services provided anywhere in the grid - such as shopping, blogs, forums, and access to private information. This is just like the services offered by large corporate providers with huge user databases; however you can be a member of this community, as well as a server on this network using a $35 Rasberry Pi. Your password isn't stored on a thousand different sites, or even worse, only on a few sites like Google and Facebook, beyond your direct control.<br><br>You cannot be silenced. You cannot be removed from the grid, unless you yourself choose to exit it.<br><br><strong><span style="font-size: 20px;">Access Control</span></strong><br><br>Zot's identity layer allows you to provide fine-grained permissions to any content you wish to publish - and these permissions extend across Hubzilla. This is like having one super huge website made up of an army of small individual websites - and where each channel in the grid can completely control their privacy and sharing preferences for any web resources they create. <br><br>Currently, the grid supports communications, photo albums, events, and files. This will be extended in the future to provide content management services (web pages) and cloud storage facilities, such as WebDAV and multi-media libraries. Every object and how it is shared and with whom is completely under your control.<br><br>This type of control is available on large corporate providers such as Facebook and Google, because they own the user database. Within the grid, there is no need for a huge user databaseon your machine - because the grid <em>is</em> your user database. It has what is essentially infinite capacity (limited by the total number of hubs online across the internet), and is spread amongst hundreds, and potentially millions of computers. <br><br>Access can be granted or denied for any resource, to any channel, or any group of channels; anywhere within the grid. Others can access your content if you permit them to do so, and they do not even need to have an account on your hub. Your private photos cannot be viewed, because permission really work; they are not an addon that was added as an afterthought. If you aren't on the list of allowed viewers for a particular photo, you aren't going to look at it. <br><br><strong><span style="font-size: 18px;">Additional Resources and Links</span></strong><br><br>For more detailed, technical information about Zot, check out the following links: <br><br> - <a href="https://github.com/friendica/red/wiki/Zot---A-High-Level-Overview">A high level overview</a><br><br> - <a href="https://github.com/friendica/red/wiki/zot">Zot development specification</a><br><br> - <a href="https://github.com/redmatrix/hubzilla/blob/master/include/zot.php">Zot reference implementation in PHP</a> -</p> - -<h1 id="credits">Credits</h1> -<p> -Thanks to all who have helped and contributed to the project and its predecessors over the years. -It is possible we missed in your name but this is unintentional.
