<h3>SimpleX advantage:</h3>
<p>SimpleX ensures data and meta-data privacy</p>
<p>with a new protocol design – it delivers messages</p>
<p>without using senders' and recipients' identifiers,</p>
<p>unlike any other messaging platform.</p>

<h2>What is the solution?</h2>
<p>
To create secure encrypted channel you need an existing secure channel

<p>Any alternative solution can be compromised.</p>

SimpleX chat - see
<a href="https://github.com/simplex-chat/simplex-messaging" target="_blank"

It uses different encryption keys for each message queue - the key is passed via existing

<h3>Communication integrity</h3>
<p>
Each chat uses two (or more) simplex queues for duplex communication. Each message contains the
hash of the previous message to detect if messages are lost or changed.
