Starting today, <a 10 href="https://taler-ops.ch/">Taler Operations AG</a> is legally operating the 11 GNU Taler payment system in Swiss Francs open to individuals and businesses in 12 Switzerland. We consider this a public beta, primarily because at this point 13 there are no shops accepting the payment system. While a few rough edges 14 remain, we believe at this point operating the system is legal and users assets 15 are safe. We are also committed to ensuring backwards compatibility of every 16 future release to the previous release. 17 <br> 18 We encourage business owners and developers in Switzerland to set to work on 19 accepting GNU Taler. We have prepared various <a 20 href="https://tutorials.taler.net/">tutorials</a> on how to get started. We 21 encourage you to use the <a href="https://ich.taler.net/">Integrator Community 22 Hub</a> to receive community support. 23 </p> 24 <h4>About GNU Taler</h4> 25 <p> 26 GNU Taler is a Free Software payment system that preserves the privacy of 27 payers while ensuring that income is visible to authorities. Regulated 28 payment service providers use the Taler protocol to issue digital cash 29 denominated in a fiat currency. The digital cash tokens are stored in 30 electronic <a href="https://wallet.taler.net/">wallets</a> under the full 31 control of its respective owner. The payment service provider has an escrow 32 bank account holding the equivalent of all digital cash in circulation. 33 <br> 34 Merchants redeeming digital cash receive aggregate transactions over the 35 respective amount into their regular bank account. Digital cash transactions 36 happen basically instantly, and must be performed online to prevent 37 double-spending. 38 <br> 39 Support exists for <a 40 href="https://www.taler.net/papers/suerf2023en.pdf">offline 41 points-of-sales</a> to accept transactions where only the customer is 42 online. GNU Taler is <a href="">scalable</a> and technologically suitable for 43 regional currencies (such as <a href="https://netzbon.ch/">eNetzbon</a>), 44 commercial deployments (such as <a href="https://taler-ops.ch/">Taler 45 Operations AG</a>) or <a 46 href="https://www.snb.ch/en/mmr/papers/id/working_paper_2021_03">central bank 47 digital currencies (CBDC)</a>. 48 </p> 49 <h4>Changes in GNU Taler v1.0</h4> 50 <p> 51 For GNU Taler v1.0 we addressed over 200 individual issues.
