Regulated 15 payment service providers use the Taler protocol to issue digital cash 16 denominated in a fiat currency. The digital cash tokens are stored in 17 electronic <a href="https://wallet.taler.net/">wallets</a> under the full 18 control of its respective owner. The payment service provider has an escrow 19 bank account holding the equivalent of all digital cash in circulation. 20 </p> 21 <p> 22 Merchants redeeming digital cash receive aggregate transactions over the 23 respective amount into their regular bank account. Digital cash transactions 24 happen basically instantly, and must be performed online to prevent 25 double-spending. 26 </p> 27 <p> 28 Support exists for <a 29 href="https://www.taler.net/papers/suerf2023en.pdf">offline 30 points-of-sales</a> to accept transactions where only the customer is 31 online. GNU Taler is <a href="https://www.taler.net/papers/boss2022thesis.pdf"> 32 scalable</a> and technologically suitable for 33 regional currencies (such as <a href="https://netzbon.ch/">eNetzbon</a>), 34 commercial deployments (such as <a href="https://taler-ops.ch/">Taler 35 Operations AG</a>) or <a 36 href="https://www.snb.ch/en/mmr/papers/id/working_paper_2021_03">central bank 37 digital currencies (CBDC)</a>. 38 </p> 39 <h4>Changes in GNU Taler v1.6</h4> 40 <p> 41 For GNU Taler v1.6 we addressed over 200 individual issues.
