<h1 id="overview-of-subdomains">Overview of subdomains</h1>
<p>BNS names are strongly-owned because the owner of its private key can generate
valid transactions that update its zone file hash and owner. However, this comes at the
cost of requiring a name owner to pay for the underlying transaction in the
blockchain. Moreover, this approach limits the rate of BNS name registrations
and operations to the underlying blockchain’s transaction bandwidth.</p>
<p>BNS overcomes this with subdomains. A <strong>BNS subdomain</strong> is a type of BNS name whose state
and owner are stored outside of the blockchain, but whose existence and
operation history are anchored to the
blockchain. In the example table in the <a href="#resolving-bns-names">Resolving BNS
Names</a> section, the names <code class="highlighter-rouge">cicero.res_publica.id</code> and
<code class="highlighter-rouge">podsaveamerica.verified.podcast</code> are subdomains.</p>
<p>Like their on-chain counterparts, subdomains are globally
unique, strongly-owned, and human-readable. BNS gives them their own name state
and public keys.</p>
<p>Unlike on-chain names, subdomains can be created and managed
cheaply, because they are broadcast to the
BNS network in batches. A single blockchain transaction can send up to 120
subdomain operations.</p>
<p>This is achieved by storing subdomain records in the <a href="/core/atlas/overview.html">Atlas Network</a>.
An on-chain name owner broadcasts subdomain operations by encoding them as
<code class="highlighter-rouge">TXT</code> records within a DNS zone file. To broadcast the zone file,
the name owner sets the new zone file hash with a <code class="highlighter-rouge">NAME_UPDATE</code> transaction and
replicates the zone file via Atlas. This, in turn, replicates all subdomain
operations it contains, and anchors the set of subdomain operations to
an on-chain transaction. The BNS node’s consensus rules ensure that only
valid subdomain operations from <em>valid</em> <code class="highlighter-rouge">NAME_UPDATE</code> transactions will ever be
stored.</p>
<p>For example, the name <code class="highlighter-rouge">verified.podcast</code> once wrote the zone file hash <code class="highlighter-rouge">247121450ca0e9af45e85a82e61cd525cd7ba023</code>,
which is the hash of the following zone file:</p>

Figure 2: Subdomain lifetime with respect to on-chain name operations. A new
subdomain operation will only be accepted if it has a later "sequence=" number,
and a valid signature in "sig=" over the transaction body. The "sig=" field
includes both the public key and signature, and the public key must hash to
the previous subdomain operation's "addr=" field.
Thesubdomain-creation and subdomain-transfer transactions for
"cicero.res_publica.id" are broadcast by the owner of "res_publica.id".
However, any on-chain name ("jude.id" in this case) can broadcast a subdomain
update for "cicero.res_publica.id".
</code></pre>
</div>
<p>Subdomain operations are ordered by sequence number, starting at 0. Each new
subdomain operation must include:</p>
<ul>
<li>The next sequence number</li>
<li>The public key that hashes to the previous subdomain transaction’s address</li>
<li>A signature from the corresponding private key over the entire subdomain
operation.</li>
</ul>
<p>If two correctly-signed but conflicting subdomain operations are discovered
(i.e. they have the same sequence number), the one that occurs earlier in the
blockchain’s history is accepted. Invalid subdomain operations are ignored.</p>
<p>Combined, this ensures that a BNS node with all of the zone files with a given
subdomain’s operations will be able to determine the valid sequence of
state-transitions it has undergone, and determine the current zone file and public
key hash for the subdomain.</p>

<p>Unlike an on-chain name, a subdomain owner needs an on-chain name owner’s help
to broadcast their subdomain operations. In particular:</p>
<ul>
<li>A subdomain-creation transaction can only be processed by the owner of the on-chain
name that shares its suffix. For example, only the owner of <code class="highlighter-rouge">res_publica.id</code>
can broadcast subdomain-creation transactions for subdomain names ending in
<code class="highlighter-rouge">.res_publica.id</code>.</li>
<li>A subdomain-transfer transaction can only be broadcast by the owner of the
on-chain name that created it. For example, the owner of
<code class="highlighter-rouge">cicero.res_publica.id</code> needs the owner of <code class="highlighter-rouge">res_publica.id</code> to broadcast a
subdomain-transfer transaction to change <code class="highlighter-rouge">cicero.res_publica.id</code>’s public key.</li>
<li>In order to send a subdomain-creation or subdomain-transfer, all
of an on-chain name owner’s zone files must be present in the Atlas network.
This lets the BNS node prove the <em>absence</em> of any conflicting subdomain-creation and
subdomain-transfer operations when processing new zone files.</li>
<li>A subdomain update transaction can be broadcast by <em>any</em> on-chain name owner,
but the subdomain owner needs to find one who will cooperate. For example,
the owner of <code class="highlighter-rouge">verified.podcast</code> can broadcast a subdomain-update transaction
created by the owner of <code class="highlighter-rouge">cicero.res_publica.id</code>.</li>
</ul>
<p>That said, to create a subdomain, the subdomain owner generates a
subdomain-creation operation for their desired name
and gives it to the on-chain name owner.
The on-chain name owner then uses Atlas to
broadcast it to all other BNS nodes.</p>
<p>Once created, a subdomain owner can use any on-chain name owner to broadcast a
subdomain-update operation. To do so, they generate and sign the requisite
subdomain operation and give it to an on-chain name owner, who then packages it
with other subdomain operations into a DNS zone file
and sends them all out on the Atlas network.</p>
<p>If the subdomain owner wants to change the address of their subdomain, they need
to sign a subdomain-transfer operation and give it to the on-chain name owner
who created the subdomain. They then package it into a zone file and broadcast
it.</p>
<h2 id="subdomain-registrars">Subdomain Registrars</h2>
<p>Because subdomain names are cheap, developers may be inclined to run
subdomain registrars on behalf of their applications. For example,
the name <code class="highlighter-rouge">personal.id</code> is used to register Blockstack application users without
requiring them to spend any Bitcoin.</p>
<p>We supply a reference
implementation of a <a href="https://github.com/blockstack/subdomain-registrar">BNS Subdomain Registrar</a>
to help developers broadcast subdomain operations. Users would still own their
subdomain names; the registrar simply gives developers a convenient way for them
to register and manage them in the context of a particular application.
Please see the <a href="/core/naming/tutorial_subdomains.html">tutorial on running a subdomain registrar</a> for
details on how to use it.</p>
