What is a mix?
A mix is a proxy computer within a mix network, or a mix cascade, that collects the encoded messages sent by the various users of a communications network. Subsequently, it changes the codes of these messages and their order for the transmission to next mix in line. There, this procedure takes place anew. The last mix of the route, or the cascade, finally identifies the actual receiver and delivers the encoded message to them. A mix network guarantees an effective form of anonymization in the internet and works very reliably even when only one mix is working reliably.
