|
<p>Every name and subdomain in BNS has a DID. The encoding is slightly different
|
|
for subdomains, so the software can determine which code-path to take.</p>
|
|
|
|
<ul>
|
|
<li>
|
|
<p>For on-chain BNS names, the <code class="highlighter-rouge"><span class="p">{</span><span class="err">address</span><span class="p">}</span></code> is the same as the Bitcoin address
|
|
that owns the name. Currently, both version byte 0 and version byte 5
|
|
addresses are supported (i.e. addresses starting with <code class="highlighter-rouge">1</code> or <code class="highlighter-rouge">3</code>, meaning <code class="highlighter-rouge">p2pkh</code> and
|
|
<code class="highlighter-rouge">p2sh</code> addresses).</p>
|
|
</li>
|
|
<li>
|
|
<p>For off-chain BNS subdomains, the <code class="highlighter-rouge"><span class="p">{</span><span class="err">address</span><span class="p">}</span></code> has version byte 63 for
|
|
subdomains owned by a single private key, and version byte 50 for subdomains
|
|
owned by a m-of-n set of private keys. That is, subdomain DID addresses start
|
|
with <code class="highlighter-rouge">S</code> or <code class="highlighter-rouge">M</code>, respectively.</p>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>The <code class="highlighter-rouge"><span class="p">{</span><span class="err">index</span><span class="p">}</span></code> field for a subdomain’s DID is distinct from the <code class="highlighter-rouge"><span class="p">{</span><span class="err">index</span><span class="p">}</span></code> field
|
|
for a BNS name’s DID, even if the same created both names and subdomains.
|
|
For example, the name <code class="highlighter-rouge">abcdefgh123456.id</code> has the DID <code class="highlighter-rouge">did:stack:v0:16EMaNw3pkn3v6f2BgnSSs53zAKH4Q8YJg-0</code>,
|
|
because it was the first name created by <code class="highlighter-rouge">16EMaNw3pkn3v6f2BgnSSs53zAKH4Q8YJg</code>.
|
|
However, <code class="highlighter-rouge">16EMaNw3pkn3v6f2BgnSSs53zAKH4Q8YJg</code> <em>also</em> created <code class="highlighter-rouge">jude.statism.id</code>
|
|
as its first subdomain name. The DID for <code class="highlighter-rouge">jude.statism.id</code> is
|
|
<code class="highlighter-rouge">did:stack:v0:SSXMcDiCZ7yFSQSUj7mWzmDcdwYhq97p2i-0</code>. Note that the address
|
|
<code class="highlighter-rouge">SSXMcDiCZ7yFSQSUj7mWzmDcdwYhq97p2i</code> encodes the same public key hash as the address
|
|
<code class="highlighter-rouge">16EMaNw3pkn3v6f2BgnSSs53zAKH4Q8YJg</code> (the only difference between these two
|
|
strings is that the first is base58check-encoded with version byte 0, and the
|
|
second is encoded with version byte 63).</p>
|
|
|
|
<p>You can see this play out in practice with the following code snippit:</p>
