      </code></pre><h2 id="howitworks">How It Works</h2>
      <p>CryptPad uses a variant of the <a href="https://en.wikipedia.org/wiki/Operational_transformation">Operational transformation</a> algorithm which is able to find distributed consensus using a Nakamoto Blockchain, a construct popularized by <a href="https://en.wikipedia.org/wiki/Bitcoin">Bitcoin</a>. This way the algorithm can avoid the need for a central server to resolve Operational Transform Edit Conflicts and without the need for resolving conflicts, the server can be kept unaware of the content which is being edited on the pad.</p>
