If the Mixes of a cascade are spread over several countries, the law enforcement agencies of all these countries would have to work together to reveal someone's identity. It was pointed out though that the new feature was covered by the AN.ON threat model and not a security leak by itself.ДЄs a reaction to the threat from local authorities, the system has spread internationally. Tracing activities back in the past is still technically not possible for the operators, but anonymity now extends only to the time-point that a surveillance court order is issued.

For the Dresden Mix, the feature continues to be part of their software until today.

The feature was made transparent by publishing the changed source code on August 18, 2003, and subsequently criticized by many users. AN.ON then decided to introduce a crime detection function in the server software in order to make this possible. In July 2003, the German BKA obtained a warrant to force the Dresden Mix operators to log access to a specific web address, which was hosting child pornography. However, all Mix operators have to sign a voluntary commitment not to keep such logs, and for any observer it is difficult to infiltrate all operators in a long cascade. The online activities of the user can be revealed only if all Mixes of a Cascade work together by keeping log files and correlating their logs.

Cost free Cascades are still in operation, although they do not offer the low latency, multiple Mixes per Cascade or guaranteed bandwidth the commercial ones do. As contractors of Jondos GmbH must ensure sufficient throughput of their mixes, anonymous web browsing at speeds 30-50вЂ‰kBit/s is possible. JonDonym mix cascades are mostly operated by SMEs in multiple countries and mix cascades always include three mix servers for advanced security. ДЄs a consequence, the JAP client has been renamed to JonDo and the service itself from AN.ON to JonDonym. Jondos GmbH has taken over development and continues to work on an improved blocking resistance function that would make it easier for users from restrictive countries to get a connection to the system. Use of JonDonym has been (and still is) free, but since financial backing of the original university research project ran out on 22 June 2007, a startup, Jondos GmbH, was founded by members of the original project team. More users on a cascade improve anonymity, but a large number of users might diminish the speed and bandwidth available for a single user.Д¬ost, name change and commercial service The speed and availability of the service depends on the operators of the Mixes in the cascades, and therefore varies.

As discussed below, solutions like international distribution of the relays and the additional use of Tor can somewhat mitigate this loss of independence. This has for example led to the issues mentioned below, where court orders essentially gave all control over the whole system to the German government.

However, it means that all the relays used for JonDonym-mediated connections are known and identified, and therefore potentially targeted very easily by hackers, governmental agencies or lobbying groups. This is different from peer-to-peer based anonymity networks like Tor and I2P, whose anonymization proxies are anonymous themselves, which means the users have to rely on unknown proxy operators. Users may choose by themselves whom of these operators they will trust, and whom they won't. a group of anonymization proxies) offered by independent organisations. The JonDonym client program allows the user to choose among several Mix Cascades (i.e.
