Turkish courts upheld the state ordered ban of    Wikipediaon    Friday, according to Voice of America. The crowdsourced    encyclopedia has been inaccessible in Turkey since the end of    April, asThe Washington Post reported, since the    administration of Recep Tayyip Erdoandeclared it a    threat to national security.  
    In response, hacktivists have made a copy of Turkish Wikipedia and posted it    online using a new way of addressing web content called the    InterPlanetary File    System, or IPFS. The Turkish government cant block this    copy of Wikipedia because the format uses a slew of open source    technology to change the way our browsers retrieve data. Its a    decentralized system, which allows the same set of data to live    in multiple places while still enabling browsers to find any    one of them with only a single address.  
    Turkey was able to block Wikipedia because the site has an    address that goes to a real place (that place is a server), so    if they block the wires that lead to that place, they can block    the site. IPFS doesnt address data with a location, it    addresses it by identifying the content itself. The system goes    out and finds the nearest copy of that content. Block access to    one copy, and it will just find another copy.  
    In a talk at TEDxSan Francisco, Juan Benet, the originator of    IPFS, explains the shortcomings of the current way we address    content on the web using the example of a physical library.  
    Imagine we could only reference books by the physical    location of one copy, he says. So, in other words, you want to    readTo Kill a Mockingbird. You go to look it up    and the file catalog tells you that the only place you can find    the book is in one library, in one room, against one wall and    at the end of one shelf. When you go there and its not there,    youre out of luck.  
    Of course, you didnt care about reading that exact copy    ofTo Kill a Mockingbird.Youd be    happy to read any copy. Thats what the IPFS does online. It    encourages copies to live on lots of servers, and the internet    works better when data doesnt have to retrieved from far away.    It also knows how to verify that each copy is exactly the same,    that not one bit of data has been changed.  
    We previously reported on a recent Spotify acquisition,    Mediachain, that used similar technology to track the    attribution of online content.  
    Pages change online all the time, but thats fine too. IPFS    also knows how to keep track of versions of a file. It can show    you the latest updateof a page, but it can also find    prior versions. Version control is a critical aspect of how    Wikipedia works as well, and it was key when we dug into the    whitewashing of the entry concerning     a noted 80s banking crook.  
    It isnt just state actors that can block our access to    content. The current addressing system is vulnerable to        large scale denial-of-service attacks. Even though most of    these attacks arent able to take down sites or cant do it for    long, they still end up costing service providers money, costs    that they then forward on to us.  
    In a decentralized system, it would be very complicated to pull    off a DDoS attack against every copy of a site, and even if an    attacker found every copy, the publisher could just make more.    It gives the good guys a way to go on the offensive.  
    The internet is the planets most important technology, Benet    says in his talk, and he believes it can work better. This    demonstration with a cached copy of a recent version of Turkish    Wikipedia is a good early test.  
    Find the first copy the IPFS teamposted here. If updated versions are saved, the    latest copy can always be found here. There are lots of other ways    to find these files right now, though most of the others    require some help from technical friends, but software to    enhance the systems usability should be in the field very    soon.  
    Moving forward, the IPFS developers hope to create a read/write    version of Wikipedia, so the encyclopedia can function on IPFS    the same way it does on HTTP now, permitting anyone who finds    it to edit its content.  
    Which would also mean that no one could stop users from editing    the site either, making its information nearly impossible to    hide.
