<h1>Spritely/Goblin<a class="headerlink" href="#spritely-goblin" title="Permalink to this heading">#</a></h1>
<p>The Spritely Institute is likely the closest in spirit and design to what we are considering with p2p-ld, and have significant experience having previously worked on <a class="reference internal" href="../social/activitypub.html#activitypub"><span class="std std-ref">ActivityPub</span></a>. The primary point of departure is their focus on building applications and running code, rather than structuring and sharing data — so their work is largely complementary.</p>
<p>Overlapping design choices include</p>
<ul class="simple">
<li><p>Emphasis on making a social, rather than a technological system!</p></li>
<li><p>Capability security vs ACLs - Containers of other identities might be a useful way of coordinating who gets capabilities, but implementing them as capabilities rather than access checks makes for a much richer space of interaction and mutation.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">Goblins</span></code> as “addressable entities with encapsulated behavior” are similar to <span class="target" id="index-0"></span>Containers</p></li>
<li><p>Distributed objects: we imagine containers as being instantiated in multiple places at once and being acted on by multiple actors. Spritelys use of the “Unum Pattern” focused on distributed behavior rather than distributed data is something we plan on following up on and re-evaluating some of our designs. One place we may diverge is in our emphasis of forking and activity that doesnt need to be explicitly approved: actors need not necessarily operate on the same shared object, but might make their own assertions, links, and so forth that dont directly change the object as owned by the original actor.</p></li>
</ul>
<p>Stuff we can learn from</p>
<ul class="simple">
<li><p>A lot</p></li>
<li><p>Promise Pipelining to reduce roundtrips</p></li>
<li><p>Implementation of protocol agnosticisim in OCapN</p></li>
<li><p>Discussion of safety of computing base and evaluation environment</p></li>
</ul>
<p>Their description of <em>portable encrypted storage</em> (<span class="target" id="index-1"></span>Storage; Portability) is also extremely useful:</p>
<blockquote>
<div><ol class="arabic simple">
<li><p>Documents must be <strong><span class="target" id="index-2"></span>Content Addressed</strong> and <strong>location agnostic.</strong> In other words, the name of the particular resource is based on information stemming from the content itself rather than a particular network location. Generally this name is the hash of the corresponding document in the case of immutable documents and a public key (or hash thereof) in the case of mutable documents.</p></li>
<li><p>Both <strong><span class="target" id="index-3"></span>immutable and mutable documents</strong> must be supported, with the latter generally being built upon the former.</p></li>
<li><p>Documents must be <strong><span class="target" id="index-4"></span>encrypted</strong> such that the documents can be stored in locations that are oblivious to their actual contents. Only those possessing read capabilities should be able to access the documents contents.</p></li>
<li><p>Documents should be <strong>chunked</strong> so that they are not vulnerable to sizeof-file attacks.</p></li>
<li><p>Reading (and, in the case of mutable documents, writing) documents must be accessed through abstract <strong>capabilities.</strong></p></li>
<li><p>Files must be network agnostic, meaning that they are not only location agnostic but agnostic even to a specific network structure. peer-to-peer, client-to-server, and sneakernet networks all should be supported with the same object URIs between them.</p></li>
</ol>
