Open Publish has a lot more going on that just that single repo!<p>There&#x27;s a whole suite of supporting services for interfacing with the blockchain, parsing the blockchain, creating transactions.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;blockai" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;blockai</a><p>One piece that we&#x27;re using in production and hopefully publicly releasing soon is the state engine that turns blockchain transactions in to a state of asset ownership. We run our own public access state engine endpoint behind this module so anyone can query about published documents or ownership here:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;blockai&#x2F;openpublish-state" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;blockai&#x2F;openpublish-state</a><p>We built another service called Bitstore, a content-addressable cloud storage web service that uses Bitcoin public key infrastructure for authentication and payment, and it pairs nicely.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;blockai&#x2F;bitstore-client" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;blockai&#x2F;bitstore-client</a><p>I&#x27;m on Freenode as &quot;williamcotton&quot;. You can msg me and I&#x27;ll give you a link to our staging server to show you the full system.<p>As for how IPFS relates to Xanadu, IPFS is very much interested in the &quot;permanent web&quot;:<p><a href="https:&#x2F;&#x2F;neocities.org&#x2F;permanent-web" rel="nofollow">https:&#x2F;&#x2F;neocities.org&#x2F;permanent-web</a><p><i>&quot;Where links do not break as versions change; where documents may be closely compared side by side and closely annotated; where it is possible to see the origins of every quotation; and in which there is a valid copyright system-- a literary, legal and business arrangement-- for frictionless, non-negotiated quotation at any time and in any amount.&quot;</i><p><a href="http:&#x2F;&#x2F;www.xanadu.com.au&#x2F;ted&#x2F;XUsurvey&#x2F;xuDation.html" rel="nofollow">http:&#x2F;&#x2F;www.xanadu.com.au&#x2F;ted&#x2F;XUsurvey&#x2F;xuDation.html</a><p>Open Publish is an attempt to build a content-addressable copyright system that pairs with the content-addressable delivery system that IPFS is building with the hopes to create something along the lines of what Ted Nelson was envisioning.<p>BTW, BitTorrent is another great example of a related content-addressable delivery system.<p>Content-addressable systems are at the root of Xanadu-like systems and it seems like the web is headed that way!
