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 </p> 34 <p> 35 Merchants redeeming digital cash receive aggregate transactions over the 36 respective amount into their regular bank account. Digital cash transactions 37 happen basically instantly, and must be performed online to prevent 38 double-spending. 39 </p> 40 <p> 41 Support exists for <a 42 href="https://www.taler.net/papers/suerf2023en.pdf">offline 43 points-of-sales</a> to accept transactions where only the customer is 44 online. GNU Taler is <a href="">scalable</a> and technologically suitable for 45 regional currencies (such as <a href="https://netzbon.ch/">eNetzbon</a>), 46 commercial deployments (such as <a href="https://taler-ops.ch/">Taler 47 Operations AG</a>) or <a 48 href="https://www.snb.ch/en/mmr/papers/id/working_paper_2021_03">central bank 49 digital currencies (CBDC)</a>. 50 </p> 51 <h4>Changes in GNU Taler v1.2</h4> 52 <p> 53 For GNU Taler v1.2 we addressed over 50 individual issues.
