GNU Taler is a free software-based microtransaction and electronic payment system.[3][4] Unlike most other decentralized payment systems, GNU Taler does not use a blockchain.[5] A blind signature is used to protect the privacy of users as it prevents the exchange from knowing which coin it signed for which customer.[5]

The project is led by Florian Dold and Christian Grothoff[6] of Taler Systems SA. Taler is short for the "Taxable Anonymous Libre Economic Reserves"[7][8] and alludes to the Taler coins in Germany during the Early Modern period. It has vocal support from GNU Project founder Richard Stallman.[9] Stallman has described the program as "designed to be anonymous for the payer, but payees are always identified."[10] In a paper published in Security, Privacy, and Applied Cryptography Engineering, GNU Taler is described as meeting ethical considerations – the paying customer is anonymous while the merchant is identified and taxable.[11][12] An implementation is provided by Taler Systems SA.[13][14]
