Contemporary trends are frightening: mass-surveillance is enabled by tracking consumers though payments, payment processors can and do impose economic death sentences on NGOs, business or individuals they disagree with, and oligopolies established by Big Tech charge excessive rent on their platforms in the form of high transaction fees. Alternative currencies using blockchains are mostly renowned for impractically low transaction rates, excessive energy consumption and virtually exclusive use for speculation and criminal transactions. With GNU Taler, we are creating an electronic payment system that is Free Software and (according to experts) compatible with existing regulations, including KYC, AML and GDPR. Payments are processed in existing currencies like Euros. Taler offers customers privacy when they spend their electronic cash, but at the same time ensures that income is transparent to the state (facilitating anti-corruption and tax-collection efforts). Taler scales to millions of transactions per second, and is also environmentally responsible due to transaction costs substantially below those of cash or credit cards. As a result, consumers will finally be able to make micropayments. This will provide an alternative for funding of online journalists, bloggers and content creators, relieving their current dependence on advertisement revenue for their income. As a reserve-based system, Taler also has advantages for economically disadvantaged populations, as consumers need neither a bank account nor credit-worthiness. Our Free Software implementation can be modified to accomodate disabled people and to include educational features to teach users financial responsibility. Parents will be able to set budgets and restrict purchases of their children to age-appropriate goods and services. Taler's core technology is implemented and documented (https://docs.taler.net/) by the GNUnet (e.V.) community and Taler Systems SA (a business we founded to provide commercial support). We integrated the payment system with various demonstrator applications, from Web shops (such as WooCommerce) to in-person payments via QR code or NFC. The Taler wallet is available as a WebExtension for Chrome, Firefox and Brave, and also as an App for Android. There are ongoing discussions with several central banks (ECB, SNB) about the use of Taler as a CBDC. We also have a German community bank partnering with us to bring the system into commercial operation. Several organizations (like the Tor Project and various publishers) have signed letters of intent to deploy Taler as soon as we have regulatory approval and are in operation. A demo of online services that use GNU Taler for payments is available at https://demo.taler.net/. For regulatory approval, we need to still enhance the wallet with backup functionality, improve the documentation, and find a way to fund independent security audits. Additional funding is sought to port the Taler wallet to further platforms, add financial education features that analyze a user's spending on their own device, improve the documentation, and to translate our user interfaces into more languages. We will deploy the Taler system inside the University of Applied Sciences in Bern for internal payments in Q1 2020. After this small-scale operation that requires no regulatory approval, we will complete the integration with the German bank and proceed to document the system for regulatory approval. Once approved, we will launch the system with our media partners. Various non-profits have already signalled their support (Wau Holland Foundation, Renewable Freedom Foundation, DigitalCourage, as well as many individual Ashoka fellows, including people involved with Wikipedia and Change.org). After the launch, we will work in parallel on the integration with more and more platforms and also continue to push the development of the consumer's wallet (financial education, accessibility, translation). If we can show significant up-take, we envision to eventually transition the system to become a centrally banked digital currency operated by the respective central bank as legal tender. \end{document}
