Is there any documentation about what Actor is? Can&#x27;t immediately find one. Some sort of non-marketing overview that gives rough ideas on how everything works, with pointers on where to read for the fine details.<p>I mean, are you interconnected with something (Signal interop a-la WhisperPush on CM? XMPP with OMEMO and GCM&#x2F;APN via XEP-0357? Telegram network with Axolotl overlay? Something else?) or you&#x27;re <i>yet another</i> proprietary standalone network?
