Enabling Secure Web Payments with GNU Taler
GNU Taler is an online payment system that uses Chaum’s blind signatures to provide robust unbreakable privacy for customers along with accountability for merchants. Taler avoids the the performance issues that plague Byzantine fault-tolerant consensus based solutions, and is developed entirely as free software, enabling groups outside the usual financial system to deploy online payments.
These two features, along with Taler being developerd entirely as free software, allow Taler to provide far cheaper transactions than the existing financial system, or block-chain based alternatives. In particular, Taler can realistically be deployed by groups outside the usual financial system.
We will give a demonstration of Taler and a discussion of integrating the merchant software into existing websites. We shall outline the Taler protocol, explaining how it accomplishes goals such as partial spending, and anonymous refunds.
