Privacy preserving and transparent payments
Taler is a new electronic payment system under development at Inria. Today, this website only presents the advantages our system is expected to provide. We expect to make the payment system available to the general public in 2017.
Unlike Bitcoin or cash payments, Taler ensures that governments can learn their citizen's total income and thus collect sales, value-added or income taxes. Taler is thus a currency for the mainstream economy, and not the black market.
When you pay with Taler, your identity does not have to be revealed to the merchant. The bank, government and exchange will also never learn how you spent your electronic money. However, you can prove that you paid in court if necessary.
Taler is free software from GNU implementing an open protocol. Anybody is welcome to inspect our code and integrate our reference implementation into their applications.
Taler is designed to work on the Internet. Using a so-called RESTful protocol over HTTP or HTTPS, Taler is easy to integrate with existing Web applications.
Taler uses an electronic exchange holding financial reserves in existing currencies. This means that Taler is not a new currency with the inherent currency fluctuation risks, but instead the cryptographic coins correspond to existing currencies, such as US Dollars, Euros or even Bitcoins.
