Anonymous payments

As an anonymization service we try to make it possible to pay for premium accounts anonymously.

Using prepaid cards

One can buy prepaid cards at a lot of newspaper stands, gas stations and supermarkets anonymously using cash. In Germany there is a limit of 100 €/month due to the Gesetz über das Kreditwesen (Banking Act).

JonDonym offers European users and North Americans the option to pay anonymously via paysafecard cash codes. Outlets selling paysafecard cash codes close to you may be found with the "Find sales outlets" search on the website of the provider. In order to a guarantee a smooth and anonymous deployment of cash codes you should consider the following advices:

  • Buy cash codes which fit to the premium rate you want to purchase for one-time usage. It is not possible to use more than one cash codes for one payment.

  • Refrain from checking the cash codes before using them. Use the codes immediately for your JonDonym premium account after purchasing them. Due to restrictive security settings cash codes are blocked automatically if they are entered from more than one IP address.

  • Use JonDonym for the payment. During the payment both paysafecard's website and the webshop of JonDos GmbH are accessed. In order to avoid a deanonymization by means of your IP address reliably we recommend using JonDo + JonDoFox for the payment. There are no constraints regarding the mix cascade you may want to use.

  • If your cash code got blocked automatically, please write an email to the support of paysafecard. If you provide a copy of that cash code you will get a new one which is unblocked.

Using Bitcoin anonymously

Bitcoin is a digitial peer-to-peer currency without a central and administrating institution. JonDos GmbH is accepting Bitcoins as payment for premium accounts.

Without proper precautions paying with Bitcoins is not anonymous. All transactions are saved in a publicly available "eternal logfile". Researchers of the Darmstadt University of Technology have provided an analysis of Bitcoin's anonymity on the Chaos Communication Congress 2011. Another analysis was published by D. Ron und A. Shamir. They were able to identify the IP addresses of users and link the different Bitcoin addresses of an account. For an example informations about the Bitcoin usage of Wikileaks were published. Until March 2012 Wikileaks used 83 Bitcoin addresses and got 2605.25 BTC from supporters.

As Bitcoin relies on exchanging data over the Internet you may use JonDonym in order to stay anonymous during Bitcoin transactions. Thereby, two separate problems need to get solved:

  1. Administration of your Bitcoin wallet without revealing your IP address.

    You may use a webservice with JonDo and JonDoFox to manage your Bitcoins anonymously. Blockchain and StrongCoin are offering the administration of an anonymous eWallet on their web servers. Registration at StrongCoin just needs an email address additionally and is suited for smartphones as well. Access to the wallet is protected by the commmon combination of username and password.

  2. Buying Bitcoins with a pseudonym which cannot be linked to your real identity.

    You can buy Bitcoins by cash or send cash by snail mail without bank transfer and without leaking identificable informations to the Bitcoin seller.

    • You may use the website LocalBitcoins.com to search for contacts of Bitcoin seller near your location and buy Bitcoins via in-person meeting.
    • You may use the IRC channel #bitcoin-otc in the Freenode network to contact a Bitcoin seller. Offers of sale you may find in the open order book. On IRC you may approach a prospective salesman and negotiate arbitrary methods for the money transfer. A web interface for the chat is available if you did not like an IRC client like Pidgin. You may stay anonymous by unsing JonDonym. There is an option to register a pseudonym (it is not mandatory, though) which needs an OpenPGP key. As a registered user you may earn reputation.
  3. Pay with Bitcoins

    If you buy virtual goods like JonDonym premium coupons you can pay it anonymously with Bitcoins. If you buy real world goods keep in mind you have to give out a shipping address which may compromise your Bitcoin account. Do not use an anonymous Bitcoin account for this purpose. Create a new account and don't link both accounts together.
