 <h2>SimpleX platform</h2>
 <p>We are building a new platform for distributed Internet applications where privacy of the messages <em>and</em> the network matter. <a href="https://github.com/simplex-chat/simplex-chat">SimpleX Chat</a> is our first application, a messaging application built on the SimpleX platform.</p>
 <h3>The first (and the only?) messaging platform without user identifiers of any kind - 100% private by design!</h3>
-<p>To protect identities of users and their connections, instead of user identifiers visible to the servers and/or the network (that are used by all other messaging platforms), SimpleX Chat uses <a href="https://csrc.nist.gov/glossary/term/Pairwise_Pseudonymous_Identifier">pairwise identifiers</a> of connections between the users – there are two queues in each connection, each queue having 2 different identifiers to send and to receive the messages. It increases the number of used identifiers to the square of the number of users, making it more difficult (or impossible) to determine who is talking to whom. I <a href="./20220711-simplex-chat-v3-released-ios-notifications-audio-video-calls-database-export-import-protocol-improvements.md#why-having-users'-identifiers-is-bad-for-the-users?">wrote previously</a> why it is bad for the users' privacy to have any identifiers, even random numbers, associated with their profiles.</p>
