We thank CodeBlau for their work, and NLnet and the European Commission's Horizion 2020 NGI initiative for funding this work.

Exchange ready for external security audit

2020-04-01

We received a grant from NLnet foundation to pay for an external security audit of the GNU Taler exchange cryptography, code and documentation. We spent the last four months preparing the code, closing almost all of the known issues, performing static analysis, fixing compiler warnings, improving test code coverage, fuzzing, benchmarking, and reading the code line-by-line. Now, we are now ready to start the external audit. This April, CodeBlau will review the code in the Master branch tagged CodeBlau-NGI-2019 and we will of course make their report available in full once it is complete. Thanks to NLnet and the European Commission's Horizion 2020 NGI initiative for funding this work.

GNU Taler v0.5.0 released

2018-04-01

We are happy to announce the release of GNU Taler v0.5.0. The main new feature is customer tipping, which allows merchants to pay small rewards directly into a customer's wallet. Technical improvements include numerous performance improvements and bug fixes, as well as a new, simpler to use API for merchants that also enables the implementation of GNU Taler wallets on platforms that do not support WebExtensions.

Taler Web Payments paper published

2016-09-01

We just finished the camera-ready version of our paper on how to use Taler for Web payments. This paper does not discuss the cryptography behind Taler, but focuses on the practical aspects of how the wallet and the merchants interact over the Web. Hence, this paper should be a good read for anyone who wants to integrate Taler support with their Web site. We have posted the paper here.
