|
|
|
<p>Registering a BNS name costs cryptocurrency. This cost comes from two sources:</p>
|
|
|
|
<ul>
|
|
<li>
|
|
<p><strong>Transaction fees:</strong> These are the fees imposed by the cost of storing the
|
|
transaction data to the blockchain itself. They are independent of BNS, since
|
|
all of the blockchain’s users are competing to have their transactions included
|
|
in the next block. The blockchain’s miners receive the transaction fee.</p>
|
|
</li>
|
|
<li>
|
|
<p><strong>Registration fees:</strong> Each BNS namespace imposes an <em>additional</em> fee on how
|
|
much a name costs. The registration fee is sent to the namespace creator
|
|
during the first year that a namespace exists, and is sent to a burn address
|
|
afterwards. The registration fee is different for each name and is
|
|
determined by the namespace itself, but can be queried in advance by the user.</p>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>Registering a name takes two transactions. They are:</p>
|
|
|
|
<ul>
|
|
<li>
|
|
<p><strong><code class="highlighter-rouge">NAME_PREORDER</code> transaction</strong>: This is the first transaction to be sent.
|
|
It tells all BNS nodes the <em>salted hash</em> of the BNS name, and it pays the
|
|
registration fee to the namespace owner’s designated address (or the burn
|
|
address). In addition, it proves to the BNS nodes that the client knows about
|
|
the current state of the system by including a recent <em>consensus hash</em>
|
|
in the transaction (see the section on <a href="#bns-forks">BNS forks</a> for details).</p>
|
|
</li>
|
|
<li>
|
|
<p><strong><code class="highlighter-rouge">NAME_REGISTRATION</code> transaction</strong>: This is the second transaction to be
|
|
sent. It reveals the salt and the name to all BNS nodes, and assigns the name
|
|
an initial public key hash and zone file hash</p>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>The reason this process takes two transactions is to prevent front-running.
|
|
The BNS consensus rules stipulate that a name can only be registered if its
|
|
matching preorder transaction was sent in the last 24 hours. Because a name
|
|
must be preordered before it is registered, someone watching the blockchain’s
|
|
peer network cannot race a victim to claim the name they were trying to
|
|
register (i.e. the attacker would have needed to send a <code class="highlighter-rouge">NAME_PREORDER</code>
|
|
transaction first, and would have had to have sent it no more than 24 hours
|
|
ago).</p>
|
|
|
|
<p>Registering a name on top of the Bitcoin blockchain takes 1-2 hours. This is
|
|
because you need to wait for the <code class="highlighter-rouge">NAME_PREORDER</code> transaction to be sufficiently
|
|
confirmed before sending the <code class="highlighter-rouge">NAME_REGISTRATION</code> transaction. The BNS nodes
|
|
only register the name once both transactions have at least 6 confirmations
|
|
(which itself usually takes about an hour).</p>
|
|
|
|
<p>Names are registered on a first-come first-serve basis.
|
|
If two different people try to register the same name at the same time, the
|
|
person who completes the two-step process <em>earliest</em> will receive the name. The
|
|
other person’s <code class="highlighter-rouge">NAME_REGISTRATION</code> transaction will be ignored, since it will
|
|
not be considered valid at this point. The registration fee paid by the
|
|
<code class="highlighter-rouge">NAME_PREORDER</code> will be lost. However, this situation is rare in practice—
|
|
as of early 2018, we only know of one confirmed instance in the system’s 3+ years
|
|
of operation.</p>
|
|
|
|
<p>Fully-qualified names can be between 3 and 37 characters long, and consist of
|
|
the characters <code class="highlighter-rouge">a-z</code>, <code class="highlighter-rouge">0-9</code>, <code class="highlighter-rouge">+</code>, <code class="highlighter-rouge">-</code>, <code class="highlighter-rouge">_</code>, and <code class="highlighter-rouge">.</code>. This is to prevent
|
|
<a href="https://en.wikipedia.org/wiki/IDN_homograph_attack">homograph attacks</a>.
|
|
<code class="highlighter-rouge">NAME_REGISTRATION</code> transactions that do not conform to this requirement will be
|
|
ignored.</p>

<p>The consensus hash must be included in the <code class="highlighter-rouge">NAME_PREORDER</code> transaction. The BNS

<p>Registration happens through a BNS client, such as the <a href="https://github.com/blockstack/blockstack-browser">Blockstack
|
|
Browser</a> or
|
|
<a href="https://github.com/blockstack/blockstack.js">blockstack.js</a>.
|
|
The reference BNS clients manage a local Bitcoin wallet, calculate transaction fees
|
|
dynamically and automatically, and broadcast both the <code class="highlighter-rouge">NAME_PREORDER</code> and
|
|
<code class="highlighter-rouge">NAME_REGISTRATION</code> transactions at the right times.</p>
|
|
|
|
<p>If you want to make your own registration client, you should see the
