The GNU Taler project, promoted by the Free Software Foundation and developed in the GNU framework in collaboration with INRIA,
 is a new free software system for electronic payments under development.

Unlike BitCoin or cash payments, Taler will be aimed at ensuring that governments can easily track their citizens’ income and thus collect sales, value-added or income taxes. Taler will not be a new currency, but use an electronic mint holding financial reserves in existing currencies such as U.S. dollars, euros or bitcoin.
