<p><strong>Namecoin</strong> is an experimental open-source technology which improves decentralization, security, censorship resistance, privacy, and speed of certain components of the Internet infrastructure such as DNS and identities.</p>
<p>(For the technically minded, Namecoin is a key/value pair registration and transfer system based on the Bitcoin technology.)</p>
<p><em>Bitcoin frees money – Namecoin frees DNS, identities, and other technologies.</em></p>
<div class="row">

<h2 id="what-can-namecoin-be-used-for">What can Namecoin be used for?</h2>
<ul>
<li>Protect free-speech rights online by making the web more resistant to censorship.</li>
<li>Human-meaningful Tor .onion domains.</li>
<li>Decentralized TLS (HTTPS) certificate validation, backed by blockchain consensus.</li>
<li>Access websites using the .bit top-level domain.</li>
<li>Attach identity information such as GPG and OTR keys and email, Bitcoin, and Bitmessage addresses to an identity of your choice.</li>
</ul>
</div>
<div class="col-md-6">
<h2 id="what-does-namecoin-do-under-the-hood">What does Namecoin do under the hood?</h2>
<ul>
<li>Securely record and transfer arbitrary names (keys).</li>
<li>Attach a value (data) to the names (up to 520 bytes).</li>
<li>Transact the digital currency namecoins (NMC).</li>
<li>Like bitcoins, Namecoin names are difficult to censor or seize.</li>
<li>Lookups do not generate network traffic (improves privacy).</li>
</ul>
<p><strong>Namecoin</strong> was the first fork of <a href="https://bitcoin.org">Bitcoin</a> and still is one of the most innovative “altcoins”. It was first to implement <a href="https://bitcoin.stackexchange.com/questions/273/how-does-merged-mining-work">merged mining</a> and a <a href="/dot-bit/">decentralized DNS</a>. <strong>Namecoin</strong> was also the first solution to <a href="https://en.wikipedia.org/wiki/Zooko%27s_triangle">Zooko’s Triangle</a>, the long-standing problem of producing a naming system that is simultaneously secure, decentralized, and human-meaningful.</p>

<p><strong><a href="/2025/09/27/encasha-off-chain-sshfp-records.html">2025-09-27</a></strong> Since Encaya now supports off-chain <code class="highlighter-rouge">TLSA</code> records (used for TLS server authentication), this begs a question: can something similar be done for <code class="highlighter-rouge">SSHFP</code> records (used for SSH server authentication)?</p>

<p><strong><a href="/2025/09/23/is-post-quantum-namecoin-tls-feasible.html">2025-09-23</a></strong> As the shelf life of most public-key cryptography nears its quantum-induced termination, many protocols are moving toward post-quantum (PQ) cryptography. PQ crypto, defined as cryptosystems that are believed to be secure against both classical and quantum cryptanalysis, is an active research area, with rapid advances happening in both the cryptosystems and the attacks. It would be nice if we had more time to research secure PQ cryptosystems, but alas we do not have that luxury. TLS is thus beginning to deploy PQ crypto. Which begs the question: how is Namecoin affected by PQ crypto adoption in TLS?</p>

<p><strong><a href="/2025/09/20/generate-nmc-cert-is-now-ncgencert.html">2025-09-20</a></strong> If you’ve used <code class="highlighter-rouge">generate_nmc_cert</code> to set up a Namecoin TLS server, you’ve probably found the interface a tad vexing. Examples of such weirdness:</p>

<p><strong><a href="/2025/09/11/hashed-tlsa-records-in-encaya.html">2025-09-11</a></strong> As long-time readers will be aware, probably the biggest innovation of Namecoin’s TLS functionality is that it uses a special form of TLS certificates that happens to work well in mainstream web browsers, via the interoperability magic of AIA and PKCS#11. This avoids having to patch web browsers or intercept TLS connections (either of which would introduce nontrivial security liabilities).</p>

<p><strong><a href="/2025/09/07/whats-maximum-length-aia-issuer-url-windows-11-cryptoapi.html">2025-09-07</a></strong> For those of you who haven’t seen my various conference talks about Namecoin TLS, AIA (<em>Authority Information Access</em>) is a mechanism for a TLS certificate to provide a URL where you can find the certificate of its issuer. Namecoin does some, uh, <em>creative</em> things with AIA. For reasons that will be elaborated on in a future post (don’t worry, all will be explained there), I wanted to know the maximum length of the URL that AIA can link to.</p>
